Gruedorf Post 2021-02-21

THIS again.

I’ve actually been pretty diligent about development for a while now (despite all of the… everything). This year, I’ve resolved to start being more vocal about what I’m up to, so I can try to build some momentum for an eventual release, and I’ve started by doing biweekly #screenshotsaturday posts on my Twitter account, https://twitter.com/shamuspeveril. After seeing a bunch of people posting here, I figured I’d join in. I’m trying to be protective of my time so that I don’t just end up spending all my time talking about the game instead of making it, but here I am for now. I’m going to be a bit indulgent of my rambling side in this first post; later posts should be more focused.

So, what am I working on?

Ancient History

Let’s start way back in the halcyon days of early 2004. I was feeling the game-making itch again. I decided to look up this old game engine I’d spent a lot of time chatting about and messing around with (and accomplishing very little) years before - Verge! I happened to load it up just a short bit after vecna had made an update saying that Verge 3 was right around the corner. Exciting! What a great time to dive back in!

Journey to Black Mountain

When V3 did actually release a month or so later, we all had a compo (known these days as “a game jam”) to celebrate the release and do some bug-finding. In a week, I built (with my then-girlfriend-now-wife, tulokyn) a small game, Journey to Black Mountain. It was about Kiel, a young healer, setting out to find a rare healing component to help her friend’s sister. It was pretty rough. It was basically a 2d walking simulator with some light puzzles, well before that genre was anything close to established or respected. It didn’t look great, but it had some interesting ideas (at least so I thought) and I liked the characters.

Geas

A few months later, mid-2004, there was another compo, but this time we had two weeks. I wanted to do something about the further adventures of Kiel and her friends, so I came up with another story about them, set five years later. With twice as much time, I obviously planned roughly 10 times as much game, and it went about as well as you expect. We got something submitted but it was very, very far short of what I wanted to do. There were rudimentary bits of the game in there – a combat system, a shop system – but it wasn’t anything remotely complete.

Post-compo Development

After the compo, I did not want to let it go. I liked the characters, and I liked the idea. Worse (?), I had some MORE ideas. I decided I’d keep working on it, and if I’m going to keep working on it, why not expand it into a full game? Why be beholden to the idea I had for a two week game jam? So I kept working on it, developing the systems further and further. I also expanded the story; the original game idea became the first chapter of seven, four playable characters became twelve, and the world ballooned in size (though I will say that I kept myself to a relatively “manageable” world size; the game was contained mostly within a few relatively small kingdoms which I wanted to make fairly dense and interesting, rather than spanning a whole planet with exactly six towns on it).

I released a tech demo of this version in late 2004, and generated some mild excitement!

Rewrite

Unfortunately I started to hate it. As I worked, I got better at coding and art and wanted to bring it up to speed. I brought some people onboard to help me, and as is the way with things, they drifted away. Verge3 got the ability to use Lua instead of VergeC for scripting, and it’s just a much nicer language to work in. Rather than convert everything, I started over from scratch; according to file dates I think it looks like I started new sprites in mid-2006. I drew new sprites and new tiles, made new maps. I ported over some of the systems and rebuilt others. At this point I started numbering my attempts at Geas, optimistically starting with “01”, so just in case I hit my 10th rewrite the directories would still sort correctly. This version looked nice, I still think it does. I worked on this for a couple of years, until some time in 2008. I sat down and worked out that at my current rate of work, it would take me dozens of years to finish.

Cutbacks

That was more than a little disheartening. I decided to change tack, and mercilessly cut huge swaths of what I’d added. I didn’t want to go back to the single “first chapter” idea, because I’d thought too much about the rest of the world, but I cut back the seven chapters to three, and the twelve playable characters to only five, and you’d only ever have access to four at once. The broad strokes of much of the story was there, but I cut out a lot of the later parts of it (which, conveniently, were also the least fleshed out anyway). I cut back the resolution to my old friend 320x240, and started over again.

This was version was what I posted about primarily when I was doing Gruedorf the first time. I made some decent headway, and worked on it until some time in 2010. As with the other versions, though, work on it (along with Gruedorf participation across the board) kind of petered out. Other projects, and other life things, started taking up more of my time.

It’s Just Sleeping

It stayed dormant for a long time. It never really left my thoughts, really, but I wasn’t actively working on it. It was always something I would do in the future, when the time was right. One of the things that I decided wasn’t right for it, anymore, was Verge. Like Geas, it had dried up and development on it basically ceased. There were enough eccentricities and problems with it that I didn’t want to go back to it. I started investigating other things, with the idea that I would eventually get to it.

I tried a few engines, I built a few, even. The most recent was Cozy, a web-technology-based engine. It owes a lot to Verge, really, both in the way I structured things, and many of the things I made them the way they are because I wanted to fix a problem I’d always had with Verge. I built SimpleQuest in that engine, but in the back of my mind what I was building was the Engine That Would Be Used For Geas. I built it, and I released SimpleQuest.

I’d poured a lot of time into building Cozy into the engine I wanted to use for Geas, and I love a lot about the engine. Once SQ was out and done, though, I took some time to really look at it, and see if it fit what I wanted for Geas, and I decided that it didn’t. I was also sick of spending time building engines; looking at Cozy, I saw years of tinkering and tweaking and support, not jumping into more games. That’s why it’s on hiatus, and hasn’t been touched in some time.

I learned a lot building Cozy, though, including what parts of making the game I enjoy and am good at and can do quickly, and which parts I fail at one of those. It also helped me realize that I just do not want to build my own engine. It’s not that I can’t (obviously), it’s just not where I find joy in making games. So I went back to looking at engines. I made myself pro-and-con lists for various engines. There were strong contenders, and I started building prototypes, but I ultimately settled on Godot. It’s not perfect, but it’s the best fit I’ve found so far.

So, back to Geas!

Well… not quite.

What

When I decided to work with Godot, I built an RPG prototype. A little dungeon-y thing that had no real “game” or “story” to it, just a map that had the various things you might do in a Zelda-style game in it. I was satisfied that I could build an RPG in it, and would be reasonably happy doing that. And then I built something else.

I was still looking for excuses not to start on Geas. At this point, there’d been 15+ years of thought and work building it up into a Very Big Thing, and so I looked for reasons not to start on it. Last September, though, in a conversation with friends I realized what I was doing, and I decided it was time to just stop. To stop looking for a reason to avoid it, to look for other unrelated games to make first, and to make a real step towards it.

First thing was to finally document some things. I’ve been holding a lot about Geas in my head, and not keeping it written down. Don’t be like me, kids. I know have the majority of the plot and other ideas I’ve had kicking around written down (unless I forgot them, in which case they are lost to time).

One of the thoughts I’d had in the years about Geas is that Journey to Black Mountain, the initial game, is actually pretty important to the overall character arcs of many of the main characters. The further Geas got from “the next compo game I made” the more it seemed important to make that story accessible in some way other than digging an ancient Verge game out of the archives. I toyed with the idea of making it a small game-within-a-game as a flashback, or something like that.

I decided that, to really make progress toward Geas, I would start with remaking Journey to Black Mountain. I’m keeping the setting, the characters, and the overall point of the plot from the original and throwing out the rest. I’m using this as a way to build a “chapter” of the larger story, and I’ll release it as its own thing. The idea is to cement my understanding of the engine, build myself a library of code and art to lay the foundations for Geas, and to get something out there so I can tweak the foundation so Geas has the best shot it can get.

Black Mountain

So to that end, I’m now building Black Mountain, a complete rewrite and rebuild of the original Journey to Black Mountain story.

I’m working with placeholder art now, that I’m making entirely myself. Current goal is to get a complete end-to-end “draft” version of the game done as quickly as possible, and then figure out how to polish it into a real game. Future plans include potentially another “prequel” game, and then Geas, broken up into chapters and released as such. I’m not entirely decided on whether I’ll keep a stripped down version of it, or go back to the full thing, but I’m leaning toward the latter at the moment. For now, I’m focusing on making Black Mountain stand on its own and to learn as much as possible from it.

At this point, I actually have a lot of the foundational programming work done. Godot does a lot for you but it’s still a generic game engine, so I’ve been focusing on building all the parts I’ll want – maps, exploration, combat, items, equipment, shops, skills, etc etc. It’s pretty close to a real game. I have a bug list as long as my arm (and that’s WITHOUT extensive playtesting with others) and a few core things left to figure out (and procrastinating on those is why I’m here writing my Geas auto-biography). Once I get those sorted out, it’ll be full steam ahead on the draft assets and writing.

See you in a week, maybe.

• Can now add water polygons to the map
• Set up z-indexing so I can have multi-part entities that sort correctly
• Built a “follower” system for having party members on map, but commented it out
• Can now add shadow polygons to the map
• Drop shadows on character entities are not part of the sprite now, they’re an actual shadow
• Started work on hopping off cliffs

Water Polygons

While Black Mountain is a relatively low resolution game and the end result will probably be mostly pixel art, I am not trying to mimic any particular old hardware, nor am I holding myself to any sort of purity test. I am doing my best to avoid actual mixed resolution (because I personally hate it), but I am not going to avoid using modern conveniences like shaders or polygons to do things. The water can be added to a map similar to an entity, but by drawing out a polygon (which Godot’s built-in tools make pretty easy). It is animated, rippling slowly and wobbling the underlying tiles of the background, and I am able to give it a direction for the movement so I should be able to use it for (slow-moving) rivers as well.

Multi-part entities

One thing that I always find annoying with making maps is dealing with thin upright pieces – things that you want the character’s head to render in front of when they’re standing in front of them, and you want the character’s feet to render behind them when they’re standing behind them. To make this easier on myself I actually have a lot of “placeables”, which are basically furniture, and are just entities like the character sprites. I put them in with the sprites on the map layer and they get sorted appropriately.

Unfortunately, this means that you have to be careful with exactly how it’s drawn. Every entity has an origin – for the character it’s the space right between their feet. The origin is the y-position used to determine render order. If the character’s origin is higher on the screen than the placeable’s origin, it gets rendered behind. If it’s lower, it gets rendered in front.

But what about things like rubble strewn on the ground? A treasure chest with coins spilling out of it? This is fine as long as the “floor” layer of the sprite is entirely contained to below its origin, but that’s not always the case, and when that happens you end up with rocks, seemingly lying on the ground, floating on top of the player when they walk there.

To allow for this, entities can now have other parts. Godot has a built in z-index system that gives you an extra means of control over the render sorting that’s happening. It’s a little bit brittle; it’d be easy to make something draw entirely wrong. If I were worried about other people using this I would probably try to do something about it, but if I shoot myself in my own foot, well, I know who to blame.

Shadow Polygons

I feel like any game where you can see the ground beneath the feet of the character benefits from having a drop shadow. I had a drop shadow under the character before, but it was just a hand-sketched partially transparent circle.

The problem with partially transparent things, of course, is that when they overlap, you get a darker spot. This is fine for Venn diagrams but not so much for shadows. So to fix that, I added a shadow layer to my maps.

The shadow layer can have shadows added to it by an entity that lives on the map (or is placed there), and it can also just have shadows added directly to it by the map maker. It works by drawing all of the shadow polygons to a separate surface, and then drawing that surface all at once with transparency. As you can see in the screenshot, the shadows lie underneath the sprites and on top of the background layer of tiles… but it is underneath the foreground layer of tiles. The real assets for the game are going to have to be constructed to deal with this; I’m not exactly sure how I’ll do it but I’m confident I’ll figure it out and that’s good enough for this stage of development. Also for the future is to figure out the best way to make them softer-edged.

Because it was easy, I also added a way to look up if an entity is currently standing in a shadow (other than their own). If they are, I draw them darker too.

Showing Followers on the Map

I always go back and forth on how I feel about having the rest of the party shown on the map as you explore. I could do the classic thing where everybody marches in a line that perfectly follows the leader, but I don’t feel like that would fit with Black Mountain. I put a bit of time into testing something where there are other sprites on the map and they try to catch up to you, but I didn’t really care to make the pathfinding work correctly so they just kind of got hung up on things (I’m fine with monsters getting hung up on things, since it means the player can be clever and escape from them… it’s less great when your party members are too dumb to walk around a tree to catch up to you). I also realized that having them on the map complicates some of the things I’d like to add later… so I turned them back off. I’ve still got the code so you never know, they might come back, but for now you’re just driving the leader around the map.

Hopping Off of Things

One of the things I’d like is for Black Mountain to be a game that feels better to move around in, and involves the characters doing things outside of combat on the map. This is driving a few of my core decisions about the game, and in a sense it’s pushing it a bit away from your traditional jRPGs towards an action RPG – getting a little Zelda in my Final Fantasy, if you will.

To that end, I’m going to be adding some of the staples of more action-oriented RPGs. The first was to add the ability to jump down off of cliffs. The intent of doing this is actually what drove the shadow separation work I rambled about above (along with wanting to deal with the overlapping polygons), so that I could lift the player sprite up off of their shadow to make it seem like they are falling or hovering.

This isn’t quite done. I have the hop and the fall, the shadow separation, etc working, but I’m stuck on the nitty-gritty of figuring out exactly where the character needs to land when they jump off. I know roughly what I want to do, I just need to make sure that the plan doesn’t wind up with the character stuck in a wall or being annoying to set up. Since I’m largely ignoring the grid for a lot of Black Mountain, I can’t just cheat by saying “jump down by 3 tiles”.

That’s it for now! It was actually a pretty productive week, all things considered, even though it felt like a bit of a slog at times. See you next week!

Whatever it is you do/did for the holidays, I hope it’s been enjoyable and relaxing.

Here’s hoping for 2019.

• Finished cliff hopping
• Added gap jumping
• Added block pushing
• Added blocks being pushed off cliff kind of
• Broke everything, rewrote collision handling/movement code
• Shouted my frustration at the cold, uncaring universe

Different Events

There are two classic, straight-forward styles of events in RPGs: I call them “step events” and “triggers”.

Step events are your classic events (like Verge’s zones) where when the character enters the event area, some sort of effect happens. This is good for map boundaries, stair cases, triggering cut scenes when the player character steps in a particular place, etc. (Technically my step events have some configuration which mean I can differentiate between events that I want to happen when the character just touches the edge of the event area, or if their center-point has to be inside of it; which one I use will depend on how I want to tie it to the visuals of the world.)

A trigger is something where the character must face the event area, and press a button to trigger it. These are often solid (though they don’t necessarily have to be), and are used to model doors, switches, people to talk to, soemthing interesting lying on the ground, etc. They’re something that the player is choosing to interact with directly, by pressing a button, rather than something that just sort of happens to them because they stepped in the right (or wrong) place.

I decided to add a third event that seems to be most prevalent in Zelda games, that I’m calling a “push event”. The push event has to be solid, and when you bump into it at first it acts just like a wall. After you continue pressing against it, though, then I run the event code. It’s not rocket science, but it gives me some fun things I can do with it, like requiring you to commit to jumping off of a cliff before actually doing it, or adding weight to blocks you can push – things that are in between just moving around and intentional interaction. They can keep moving through the world with only a brief interruption but also where they won’t just be flinging themselves off of cliffs or kicking boxes out of the way just because they stepped a touch too close.

So, with that I have a couple of things working now…

Hopping Off of Cliffs

I mentioned this last week, but it’s finished now. When you push against the top of the cliff polygon, it figures out where the bottom is and plays an animation of you hopping down. Right now the height can be arbitrarily tall, but it wouldn’t be difficult to add a check for height if I wanted to. If you push against any part of the cliff that doesn’t have a “bottom” below it (e.g. the bottom of the cliff) it ignores the push and just treats it as a wall.

Jumping Over Gaps

Similar to cliff jumping, you can also define a “gap” that can be jumped. Rather than jumping vertically to the bottom, it projects across the area instead and jumps you to the other side if it’s close enough. Similar to the cliff height caveat, the jumpable gap size is currently fixed (to one tile) but could be modified by an item or skill or whatever in the game.

Pushing Blocks

Entities can also be set up to receive pushes, and they work like a push event but can also be moved by the event handling. I haven’t tried it yet, but these could be set up to trigger (some) events when moving, so it should be pretty straightforward to make the classic “push a block onto a floor switch” kind of puzzle! I just need to make sure I don’t inadvertently create the “push a block out of the map and it’s gone forever” kind of puzzle. I could probably leverage this for general NPCs; there’s nothing more annoying than a villager standing in the way and you just kind of have to wait for them to decide to wander out of the way.

Pushing Blocks… Off of Cliffs

I said that I haven’t tried to set up a block “stepping” on a button yet, but I wanted to immediately tackle having blocks that are being pushed trigger other push events – specifically to have them trigger a cliff jump. It actually just kind of worked once I got everything hooked up! Except when it didn’t.

Sometimes, the push just wouldn’t register with the cliff. The player kept being able to trigger it, but the block was inconsistent. I narrowed it down a little – it seemed like the more “flat” the cliff edge was to the block, the less likely it was to trigger the event. It seemed like the issue was rooted in using Godot’s move_and_slide(), a built-in function for kinematic physics bodies which produces (close-ish to) the kind of movement I wanted out of the box… except that it for some reason it was now causing issues.

Rewriting Collision, Again

I hate writing collision and movement code. When I was building SimpleQuest I actually just kind of stopped working on it for weeks (maybe months) when I hit this wall. I didn’t want to ruin my streak of work so I just plowed in. Thankfully, things are a bit easier for me this time. But not much.

It turns out move_and_slide() is a wrapper around a lower-level movement function, move_and_collide(). I didn’t especially want to write all of my own collision detection code (since it would be an enormous waste and of time and it would almost certainly be slower than using the built-in facilities, and most importantly it came with the risk of just killing my forward momentum entirely) so realizing there was a lower-level thing to fall back to was a relief. I just need to deal with the collision resolution, not the detection.

So I re-wrote the resolution. Unfortunately, push events and push events triggered by pushed objects present a lot of issues. In particular, the sliding block will begin colliding with the player first, when squeezed between the player and a push event. This means the push event never really gets the collisions. I suspect this is what was happening internally within move_and_slide() as well. Maybe! Who knows?!

Anyway it was very frustrating but after a few hours of trial and error and reams of debug logging, I think I have it mostly working now. I’m sure I will (unfortunately) have to revisit it some day (I already know it’s not working exactly how I’d like), but at least it’s kind of there now, and I can move on to the next thing. Hopefully next week will be smoother sailing.

• Brainstormed about how I want to handle skills
• Start implementing that

Brainstorming

I wrote some last week about the trouble I’d been having with deciding how I wanted skills etc to work. I waffled a lot, and eventually started building pros and cons lists for various approaches. I ultimately ended up going with a fairly traditional route, and deferred a lot of the more unusual ideas I had for future games. I certainly could change my mind, but for now I at least have a way forward.

And Finally, Progress

I spent basically all week reaching the decision and finally came to it today. So I started implementing SOMETHING so at least I’d have a little to show off.

I’ve had a “Status” section in the menu just kind of hanging around with debug information in it. I wasn’t really sure what to do with it, but I realized that I could finally put it to use. The status section will have three (for now?) sections in it: the default info section, the “spend XP” section, and the attributes section. I may actually move these around and change what the default is, but that’s going to need some playtesting to figure out how these actually flow in practice.

The info section is pretty straightforward – it shows you info about the character. I’m undecided exactly what I’ll put here, but I’ve written a couple sentences of backstory for each character. I may add more random “demographic” information here, or I may add other interesting stuff. Not really sure yet.

Spend XP is where you’ll be “levelling up” your characters. There isn’t a traditional level system in Black Mountain; instead you use XP to buy skills and passive upgrades and such. It isn’t displayed super well at the moment, but there’s a hierarchy of upgrades you can buy, as well as levels of each. The available trees of upgrades depend on the character’s available classes and equipment. I had actually built this interface a while back, but it lived under “Skills”. I’ve moved it here, though, and will repurpose the Skills section into where you actually use your skills outside of combat.

Speaking of skills based on equipment, as I rambled about on twitter a while back, Black Mountain and later games will not have the standard jRPG equipment “treadmill”. I wanted to avoid the classic jRPG silliness of “Here is this amazing legendary sword! … That you will sell to a merchant in two hours because the sword you bought at a merchant in the next town is better”, and strive for something a little more in line with epic fantasy books. A characters’ core equipment will be a part of them, and will grow along with them – changing equipment will happen only very infrequently, and usually as an “upgrade” to an existing piece of equipment or as an expansion of options, rather than replacing them. In Black Mountain, for instance, Kiel uses the sword that her father left behind when he died; it would be ridiculous for her to just toss it aside partway through the journey. Since the equipment is more-or-less fixed (or, in later games, a very small pool), it functions partly as the character’s “class”, and so the character will have skills associated with that particular weapon. (Coincidentally this also happens to mean that I don’t have to worry about inconsistent art for different weapons.)

The last section, Attributes, isn’t done yet. It’s where I’ll show the character’s stats, but I haven’t started work on it yet, so no screenshot. I’m considering switching this to be the default screen, rather than the info section, since the info section will be (relatively?) unchanging, while Attributes may have things the player wants to check on every now and then.

At Least I’m Moving Forward Again

The last two weeks haven’t been great, but I’m glad to have made a choice. Hopefully I’ll be back to my usual productivity next weekend.

I went and made my own engine and released a game with it. Nothing big, just a little freebie on itch – https://speveril.itch.io/simplequest. I’ve got plans for more engine work (maybe even a release that other people can use!) and more games there.

The engine is pretty different than Verge in a lot of ways, but its design is definitely informed by Verge… stuff I liked and stuff I didn’t like as much.

I’m also still occasionally helping Grue with Sully but I’m kind of a flake there. Sorry, Grue.

• Added wall climbing
• Added block pulling
• Made a floor switch that clicks down when the player steps on it or puts a block on it
• Added push/pullable block constraints
• Broke wall climbing somehow
• Fixed wall climbing

Unfortunately screenshots don’t demonstrate most of these super well, but I’ll do what I can.

Wall Climbing

I can now define an area as climbable. If you push against the top or bottom of it, you’ll switch to climbing mode (which currently does not have different art) and you will be able to climb around on the surface. It’s a bit jittery and weird and I haven’t fully put it through its paces so I’ll have to revisit it at some point, but it’s working for now.

Block Pulling

I’m not making a sokoban game. I don’t necessarily want or need to derive a lot of difficulty from constraining exactly how the player can move blocks around, so some (most?) of the time I’m going to want to allow them to pull blocks when they’re able to push them. This will cut down on the possibility for the player to get stuck on puzzles; it’ll also severely curtail the actual allowable difficulty for the puzzles, so it’s something I can toggle individually for a block.

While I was at it I also made it so you can toggle pushability as well, so I can have pull-only blocks. The screenshot may be a little hard to parse, but that block has a sort of debug-graphics black bar that stretches into the wall; when you let go of it, the whole thing will slowly retract back into the wall.

Floor Switch

Having step events (as described last post) isn’t new, so this isn’t that novel, but it’s got a satisfying click to it when you step on it, and it visually changes to show it’s depressed. More importantly, the block can also push it down (but it’s even harder to get a meaningful screenshot of that than it was with the player stand-in sprite).

Block Constraints

I am able to add solid obstructions to a pushable block that constrains it from moving. These constraints are in addition to any normal solid walls, but they don’t block the player (or any other entity) from moving around. The dark polygons on the ground below both blocks in the above screenshots are just visible polygons to help me ensure they’re working correctly, the space constraint obstructions are normally invisible.

That’s All!

That’s it for this week. After the debacle of last week’s collision stuff (and the knowledge (which turned out to be correct) that I would have to delve back into it a bit for this stuff), I kind of dragged my feet on getting into it this week. I’ve got a few more map-interaction “primitives” like this stuff that I need to build, and a few that are on my “maybe” list, and then I’m mostly left with a few small features, a bug list, and “actually building out the story”. I’m looking forward to getting to that part.[0_1615760291123_climbing.mp4](Uploading 100%)

• Made a liftable block
• Changed my mind about how some things should be implemented
• Fixed liftable to fit the new way
• Angrily stared at some docs and my todo list, a lot

Lifting Blocks

To go along with pushing and pulling things, you can also now lift them, and then put them down.

The “liftable” entities play a quick lifting movement animation, which will eventually be accompanied by an animation from the character, and have the player character lift up their arms, but that’s for later. When the character puts the pot down, it triggers floor switches just like a pushable block.

Changing My Mind

Pretty much immediately after getting liftable entities working, I realized that I wanted to implement them in a different way that is more flexible. There was something more pressing to work on, and they worked! So I decided to move on.

But then, once I actually confronted the next thing to work on (see below), I decided to switch back to it and see how well the different implementation worked, and whether it was a lot of work. If it worked out, then I’d probably want to make the same change for pullable/pushables. And it did work out! I haven’t made the change to pullable/pushable blocks yet, but I will. I decided I needed to stop putting off the bigger decisions I needed to make.

Decisions

So far I’ve been implementing a lot of stuff that I’d already decided on, or seemed obvious to me – things like how equipment would work, or just basic navigating around a map. I’m starting to run out of the obvious things, and a big core part of the design that I’ve been been putting off is now an impediment to getting more done.

Black Mountain is intended to be the first in a series of games. As such, I’m building as much as I can with an eye toward re-use in the future. I am not making myself build everything I might ever want in Geas, but I am trying to at least work in that direction. Part of what I want is to have a world that’s a little more reactive than your average jRPG; rather than just invisible monsters, things that wait around to have a button clicked at them, and the ability to script some cutscenes, I want the world to have a bit of logic and physics to how the player interacts with it.

This is what’s been driving my attempts to let you maneuver gaps and cliffs naturally, pick things up, push things around, etc. Some of the things I’ve got planned for the bigger picture I have intentionally put off for this game, which is fine, I can fill them in later.

What I need to actually figure out, though, is whether there are items and skills that the player has that they use out “on the field”. Think of tools like the hookshot or the hammer in Zelda; they can be used as weapons, certainly, but they add specific and meaningful ways to traverse and manipulate the world. I don’t have a clear vision for how I want this part to work; either what tools and skills I want available to the player outside of combat, how different characters and equipment play into it, or even whether I even want to deal with them at all. Once I decide that, I can probably figure out a reasonable stripped down version for Black Mountain, but without a strong guiding idea I’ve been floundering a bit trying to figure out how to begin figuring it out.

After a few days, I am making slow progress on the decision, so I’m not completely stuck at least. I’m currently mapping out the choices I have to make, what options I could choose, and working out the implications of said choices. What I decide will end up tightly intertwined with building maps, combats, and the general minute-to-minute tension of the game, so I want to at least come up with something that feels right on paper, even if it has to change later.

• Figure out that I’ve been drawing maps to the wrong intended scale
• Figure out what the right scale is and how to draw them
• Start building out the first “dungeon” map

Maps

Maps! They’re hard. I’m building them in a bit of a strange way.

Since I’m not building the final maps for the game at the moment, I am trying to develop a workflow that strikes a balance between a couple of points:

1. It has to be relatively fast
2. It has to be relatively easy to change
3. It has to be something that I can give to artists and they can understand it all well enough that they can see how to improve it (and hopefully enjoy it as-is)

I would normally just make some tiles and use tilemaps. That’s something I pretty familiar with, but it turns out… I’m not actually very good at tile art. It takes me a long time and I fuss with it a lot. I could just use some coloured squares, but then I’m losing out on my third goal – it’s not clear what things are. I could FIND some tiles to use but I have a terrible problem that if I sit down to find “relatively good” tiles to work with, I end up looking for the PERFECT tiles. I also don’t want to be constrained by what someone else decided to put into their tileset (and if I let myself start drawing my own tiles then we end up back at the beginning of this paragraph.)

While I’m not a great pixel artist, I am semi-competent with a pencil. All of the art you see in the game so far (in earlier posts) has been drawn by me (I primarly use a Huion tablet and Clip Studio). So I’ve also been pencilling the maps.

This COULD lead to a lot of terrible waste. The first part of the game is set in a forest, so rather than signing myself up to spend the next ten years of my life drawing trees (though I’m sure I’d be quite good at drawing trees by the end), and to avoid having to fight with pasting things in the right order, I’m still using a “tile” engine internally. Godot’s Tilemaps, to be exact.

The other problem with pencilling something is that it is very easy to focus on one thing and ignore the larger picture. With tiles this is kind of okay (most of the time) because you’re focusing on some details in a tile and then piecing together the larger picture late. If you’re actually producing a map’s layout and its “pencils” in one go, though, this isn’t good. It’s a work in progress, but I’ve been gradually refining the process…

The Process

First, I start in Clip Studio. I’ve got a file where I am drawing the entire game (well, it WILL be the entire game eventually) in one big image, with blocky pixels. It’s drawing at roughly a one-fifth scale, and it looks kind of like this:

As you can see it is very light on details. I’m doing some mental planning as I work on this, and have some references within other documents (mostly in Google Drive so I can peck something into them from my phone if I come up with an idea while I’m not at my computer), but they’re quite messy. The grid is a grid overlaid by Clip Studio and it is very very roughly set at about one tile per square.

Since I have all of the maps in the one image, I can also make sure that they line up and roughly fit with each other. This is important to basically no one in the world other than me, but I like that I can do it.

When I decide to move further with a map, I make a new image that is 1:1 full size for that map, and I clip out the section I’m working on from the big “complete game” image, and blow it up to the right size. Then I start pencilling in the shape of the map over it.

I actually work with the rough map more transparent than in the image, but I upped the opacity so it was more obvious. I’m drawing in red because there is a psychological effect that black lines seem more “finished” (or so I’ve heard), and I want this to feel like a draft. It’s just a pencil drawing, so it’s not set in stone.

You’ll notice that there are some features drawn on the map, but I mentioned this is supposed to be a forest. There are no trees! Earlier in development, I pulled out three sizes of trees (cleverly named “small”, “medium”, and “large”), and I’ve divided them into the “below the player” and “above the player” parts. It turns out that Godot’s Tilemaps have a very loose definition of what a “tile” is. It can be any image – whether or not it’s the supposed size of the tile. This means I can just treat my two pieces of tree as tiles on two layers.

So I import my pencilled map into Godot, and then start dropping in the reusable parts like the trees. If they are thing that should exist on the same layer as the player (e.g. a barrel that you can both walk in front of or behind) then I have a separate “entity” layer for them.

The last step to make it useful is to put in the obstructions. I use CollisionPolygon2D instances for this, which Godot has native editing support for. It makes things very colorful.

Then I run the game and wander around to see if I messed anything up! (Spoiler: I usually did.)

Going Forward

I’ve got a lot of map drawing ahead of me. I’m not really entirely sure about this process yet; I’m worried it’s not quite fast enough. This won’t necessarily make for very exciting Gruedorf posts!

But that aside, my next several weeks will probably be a bit constrained anyway. My wife and I are gearing up to move in the while, so we’re doing the whole finding-an-apartment-and-packing-everything-we-own thing. I’m going to do my best to still post on Sundays, but I probably won’t take the time to ramble nearly as much.

Gruedorf Post 2021-06-20

• More maps
• A droppable ladder

Sunday

Hey, did you know it’s Sunday? I forgot.

Ladders

One thing that I appreciate in map design is when you traverse a map multiple times, but when as you go through you open up little short cuts for yourself. I’ve actually implemented the first instance of this in Black Mountain; a rope ladder.

You first encounter the rope ladder rolled up at the top of a cliff. There will be a small cutscene drawing attention to it (mischievous forest spirits up to no good, naturally). You’ll go far, far out of your way to work around a different path and eventually come to the top of the cliff.

If you use the ladder, it’ll flop down, and what was an impassable cliff is now a climbable area.

Aren’t you clever?

This will be useful, because just north of this area is a small boss fight (mischievous forest spirits, again) and then a town. In the town you will be tasked with doing something that involves returning to the forest and unlocking a new area – I certainly don’t want to have to walk all the way back through a damp cave system to get back and forth while testing, so why should I make the player do it?

• made enemy “AI” a little better
• add a display of the enemy name during targeting
• tweak a few places to change how a selection is highlighted to make it more obvious
• some boring (to talk about) refactoring and trying things out that haven’t gotten anywhere yet
• started on building out the village of the fae

I missed last week for personal reasons, which also led to me not getting as much done since then as I’d normally like.

Enemies

Previously, enemies had only a half-implemented partial idea for deciding what action to use, exactly. Unless they had a special script for their combat (which I use exactly once), they would always use exactly one attack; the last one they had defined. Now, though, each monster has a table of attacks they can choose from, with a weight. Here are the actions for the Gremlin monster:

"actions": [
	{ "chance": 2, "skill": "m_slam", "skill_level": 1, "target": "random" },
	{ "chance": 1, "skill": "stone_spike", "skill_level": 1, "target": "random" }
],

I do a weighted selection from the table based on the “chance” field, and then look at target. At this point, I believe every monster has all its attacks target “random”, which just means a random target. I could have it target a particular character by name and, more usefully, I intend to give myself the ability to restrict targets based on things like “has Energy left”, “the most HP”, etc. Anyway, once a skill and target is chosen, I just apply the skill (at the given skill level; any skill can scale based skill level) to the chosen target.

Weighted Selections

Actually, I want to talk a bit more about this since it’s something I’ve implemented a bunch of times. I often find myself wanting to have a table of options with different likelihoods for each thing. What I do not want to do, though, is define a bunch of percentages that all add up exactly to 100% that I then have to manually tweak each time I add something to the list. What I definitely do not want to do is wrap my head around a random selection based on iterative “rolls”, even though that would be very easy to code – this would look like “start at A and flip a coin; if it’s heads choose A, but if it’s tails then flip another coin; if it’s heads, choose B, but if it’s tails then flip another coin…”.

So instead I do this weighted choice: I just give each thing in the table a “chance”, which can be an arbitrary integer. Two entries with the same chance have the same chance of being chosen, while an entry with twice the “chance” has… twice the chance of being chosen, compared to the other. It’s very easy to reason about, and the code isn’t that hard to write. It looks like this:

func weighted_rand_from(arr, weight_key="chance"):
    var chance_sum = 0                # start out by summing the "chance" values for the whole table
    for a in arr:
        chance_sum += a[weight_key]   # notice that we use the [weight_key] parameter so it can be called whatever you need
    var n = randi_range(chance_sum)   # generate a single random number
    for a in arr:                     # step through the array,
        n -= a[weight_key]            # subtracting the chance of each entry from the "roll"
        if n < 0:                     # once we drop below 0, we've found the one we want!
            return a
    return arr[arr.size() - 1]        # return the last thing in the array as a safe default

Yes, this does involved iterating over the whole array (potentially) twice, but unless you’re using very large arrays this shouldn’t be an issue. If it ever did, you’d be farther ahead to recalculate your table into something else for your export. I doubt I’ll end up needing to worry about this for Black Mountain.

Enemy Name Display and Highlighting

I mentioned the name of one of my monsters was named a Rumble Bee internally but had to just refer to it as “the wasp monster”, and I got a bit of feedback from a playtester that it’s nice to know what the monsters are called. I tend to agree, so I added a display for them when picking a target.

Twig Sprites are one of the first enemies you encounter and probably the easiest to defeat in the game.

Along with that you can see I’ve added an extra cursor to the list of monsters. I’ve added one to the list of party members as well.

Kiel is probably going to use First Aid on Omen or something, but who knows for sure.

I’ve also added a small tweak to the character selection in the menu, for viewing status, using items, etc etc. I bump their portrait up a bit just to make it a little more obvious who you have selected. This one was suggested by Hyptosis, and it’s small but I do think it helps with clarity.

The only way Violet will ever be taller than the other two.

Village of the Fae

The next area I’m working on filling out is the Village of the Fae.

The fairies are definitely friendly and definitely won’t feed your baby to a goat.

This is a very quick paint job (and not even finished) like the rest of my map painting. I just want it to be clear and playable for the time being – it will get much prettier in the future.

Devlog 2022-06-22

• Tweak movement code to make it a little less slippery and to have less “jittering” at corners.
• Add foot step sounds.
• Add a screenshot button.
• Actually implement status effects in battle.
• Implement a couple of localization-related things.
• A bunch of refactoring.
• Small bug fixes and various tweaks.

The merchant in Shoda’s Brook, aka “Uncle Reg”. Violet’s actual uncle, and just an overall good guy to Kiel and Omen.

Another week of work! Got some new art from Hyptosis to put into the game to make the merchant’s area in town a little more cluttered.

Footsteps

I tweeted about this on Monday, and there’s a fun video to watch there, but to sum up, the player-controlled character now makes footstep sounds as they walk around. This is defined as a default for each map, plus I can define areas within the map that override that default. As an example, in the video in the tweet, the map’s default is the “grass” sound, with extra areas defined for dirt and wood.

I had actually done a little bit of investigation on this a while ago, but had decided to lay it aside for a while. It’s pretty straightforward, really, just play a sound effect every now and then as they’re walking, but my implementation has a few niceties in it that I want to talk about:

Timing: Godot has an AnimationPlayer built-in which lets you define animations on a timeline. One of the things you can add as a “keyframe” on the animation is a simple function call, so rather than trying to keep the steps synchronized correctly with timers or whatever, I just add a function call to play a footstep sound to the frames where the character’s forward foot strikes the ground. There are other ways you could accomplish this with an AnimationPlayer timeline, but I chose this so I have a little more control over which sound plays, exactly.

Override Areas: The areas for the sound effects are pretty straightforward StepEvents which push the new sound into a list when you enter the area, and remove the sound from the list when you exit it. The first pass of the implementation was a simple variable set onto the character’s footstep data, but this caused some problems when crossing from one area to another – it’s not stable whether the area-exit event or the area-enter event will fire first, even if you manage to get the edges of the two areas to line up exactly. If there’s any overlap it’s even harder to know if the area-exit handler should be touching the value or not. Having an array is a little more complex (and slightly less performant) but it is a lot easier to get right.

Sound Selection: The sound that actually plays gets selected based on whatever is at the front of the footstep list; if it’s empty, we use the default. Each type of footstep sound has a bank of 8-12 sounds to provide some variety, and the footstep code remembers the last one it played, and (so long as we have more than one footstep in the current category, because this isn’t my first time at the rodeo) it will ensure that we never play the same sound twice in a row.

Status Effects

An actual conversation I had on Monday with my friend E, who has been helping me a ton with testing the game:

Kildorf: I just implemented status effects in Black Mountain so the giant wasp monsters can poison you now
E: Goddamit
E: You put poison in your game?
E: Why don’t you just fill it with escort missions where the npcs you have to protect have 3 health too

Status effects are a staple in JRPG combat systems. I had sketched out some of the system (and, truthfully, was already using exactly one status effect for the Defend action in combat) before, but I didn’t yet have the infrastructure for building attacks that set status effects. I started, of course, with the classic “poisoned” status, which damages you each turn. The wasp-looking monsters in the game (which are, by the way, named “Rumble Bees” because they are stinging insects that are ready to fight) use a Bee Sting attack, which have a flat 50% chance of poisoning you when they hit.

Refactoring

I had an idea of something that wasn’t Black Mountain that I wanted to prototype out quickly, just to see how fast I could. Since the idea used a top-down sort of RPG movement, I wanted to just reuse what I already have in Black Mountain. I think it’s pretty good! I started a new Godot project and started copying things over and found that, despite my best intents, a lot of it needed to be reorganized or deleted or whatever. Instead of doing a bunch of refactoring in some throwaway code, I decided I’d go do some refactoring in the Black Mountain codebase instead!

This is actually pretty important to me in the longterm as well, since (and this will be no surprise to anyone who has talked to me about game development for more than five minutes) I have a lot of games I want to make, including some direct sequels to Black Mountain, so it’s something I really should just take a bit of time to do every now and then anyway.

I never did actually get around to prototyping that other idea out.

Localization

Localization is something that is relatively straightforward to include from the beginning of your game, and incredibly difficult (or at least, tedious and annoying) to retrofit in. I’m trying to opt for the first approach, even though I don’t actually know whether Black Mountain will ever be localized. It’s just good practice anyway. So I took a bit of time to flesh out some of the stubs I had in place with TODO comments saying “when I want localization to work, do this”. It’s still not quite at the point that I could truly drop in a translation, but it’s definitely closer.

Controllers in Godot

Controllers are a bit of a nuisance.

They’re a great way to control a lot of games, especially if you have vague ambitions to port to a console. Godot does a lot for making it easy to use controllers, but there’s a sticking point that I encountered and I wanted to write up how I dealt with it. I’m not going to claim this is The Best Way or anything (there are certainly some… oddities to it) but Google told me that I’m not the first to encounter this problem, and there wasn’t any solution around that I felt was acceptable.

To sum up the backstory: A long time ago, a playing card company named Nintendo released a video game console known as the Famicom, later dressed up to look like the most boring piece of consumer electronics imaginable and released as the Nintendo Entertainment System for the North American market. Perhaps you’ve heard of it. It had a controller with an A button on the right and a B button to the left. Sega, their competitor, released a system, the SG-1000 on exactly the same day (July 15, 1983), but it only had one button on the controller so who cares – a couple years later, they released the Mark III with a two-button controller, labelled 1 and 2, with 1 on the left and 2 on the right. This is where it all went wrong.

To skip a few things historically-speaking, there are a number of common, popular layouts of controllers now (and none of them are made by Sega): the XBox layout with A on the bottom, the Nintendo layout with A on the right, and the Playstation layout with symbols instead of letters and inconsistent usage of those symbols internationally.

Images clipped from Gamestop’s store pages

Godot does a great job of supporting these different controllers, but it does so at a hardware/physical level. When you set up your input map, you are mapping an action to a physical button, whatever colour/label that button has. This is great if you’re relying on muscle memory that happens to match exactly what you think is right.

The input mapping wizard in Godot.

Thing is, I’d like to, at some point, show buttons and the like that actually match (moreorless) what the controller actually looks like, and I would also like to match what the controller actually implies about what the correct confirm/cancel buttons should be. I also happen to have a Nintendo-layout controller (specifically an 8BitDo SF30 Pro) hooked up to my PC, so I get to see how many other games fail to do this at all. Anyway, seems pretty straightforward though: Godot lets you remap input via code, so just detect if the connected controller is a Nintendo layout controller and remap if necessary, right?

Unfortunately, there are only two pieces of information you get from Godot: the controller’s GUID and its name. This is great for displaying the name, potentially, or differentiating controllers manually… but I don’t really want to have to sit down and figure out the GUID for every possible Nintendo-layout controller that has ever been released (or will be released in the future?) So I decided to dig into where exactly Godot gets its gamepad information. Or, rather, dig BACK in to it, since I had reason to look this up in the past when I was testing someone else’s Godot game and discovered that my controller simply wouldn’t work at all with it.

Turns out, Godot gets its controller information from the SDL_GameControllerDB, a community-sourced database of controller GUIDs, names, and mappings. Godot has a copy of the main TXT file there in its own source, located at (at time of writing, anyway) https://github.com/godotengine/godot/tree/master/core/input. There’s also another file in there for Godot-specific mapping, mostly for browser compatibility, as near as I can tell? In any case, the mappings here are used internally to make the input system work, but does not appear to be exposed to game script at all.

So, I just grabbed my own copy of the TXT file and stuck it in my game source. It’s easy enough to parse, so at load time I now parse my own copy of the controller DB, and create a table in-memory of the mappings. I also, at launch, read the mapping for “all joysticks” out of the input map, store them in an object, and then remove the mappings. For every joystick that is currently connected (and again, any time a new joystick is connected), I re-add specific mapping for that joystick to the input map. Before I do that, though, I check the joystick’s GUID against my in-memory version of the SDL_GameControllerDB, and IF it has a map of a:b1 (which I’m using as my signal that it’s a Nintendo layout) and apply any modifications needed. This also happens to clear up the fact that I had not correctly set up my input mapping before anyway so you could only ever use the first controller plugged in. All of this, of course, falls back to the default XBox layout if they GUID isn’t in the table, so it’s not going to blow up if someone plus in something unrecognized, and to support new controllers I should just have to update my copy of the .txt file.

This also means that when I get around to putting in custom input mapping (which I consider a critical feature still to be done), I can use the same controller DB to determine what labelling should be displayed, and same anywhere in the game I want to display buttons in tutorials or whatever.

There’s still more to be done, of course – I’m not doing any remapping for Playstation controllers (since I don’t have one I can easily test with) and I know if I want to support Switch Joycons they’re a bit of a mess, so I’ll have to figure that out. Regardless, what I have in place should be pretty easily extensible for whatever controllers I need to give a little special care.

Gruedorf Post 2022-06-15

• Skipped Gruedorf for 3 months
• Got and/or drew some real art
• Finished most of the core systems
• Lots of refactoring and bug fixes
• Built a demo of the first chunk of the game (sorta)

Hi again. In my last post I closed with the words “If it comes down to it, I’ll always choose putting time into the game over posting a devlog.” That turned out to be more prophetic than I anticipated! There’s a lot to talk about and I’m not sure how much I’ll actually manage to cover but here we go.

How’s Black Mountain?

It’s actually looking pretty good, if I do say so myself. I’ve been working on it close to every day since my last post, and it has changed a lot – looks like I’ve made 390 git commits since then. Obviously, nobody has the time for an exhaustive cataloguing of each thing I’ve done, so instead I’ll just describe where I am now.

At this point I have a demo, which seems to be about 30-60 minutes of playtime (depending on how quickly you zoom around, how much time you take to look at everything, etc etc). It’s essentially the opening of the game plus the game up to the first boss, without any of the optional side areas that will be littered around. I’ve had a few people play it, and it’s been a bit buggy but feedback has been essentially positive.

The Art

In the demo, there are no (well, almost) pieces of placeholder sketch art left; everything has been updated to some level of coloured and polished. Our cast is looking much better these days.

The world is also looking better.

A lot of the background painting there is the work of Hyptosis, which should be a familiar name around the Verge community. The small pieces that aren’t from him are from me, looking very carefully at what he painted and trying to match it. It sincerely made me a better painter, and I’m even actually starting to enjoy painting, which has never been my favourite.

The cast also has far less scribbly portraits now.

These are the handiwork of my friend Cil, who I am eternally indebted to now.

Campfires

I do want to actually talk about one of the new features I added, though! I’ve got a backlog of them to talk about, I suppose, so maybe I’ll manage to work through them over time.

Spread throughout the world, there are a number of campfires. You can kind of think of these like save points, though the game allows you to save anywhere you like. A checkpoint does autosave (along with ANY map change), and it also completely restore your health and energy, and remove all adrenaline (a system in combat that I’ve added), and respawning all monsters that have been defeated. It’s sort of a reset point to let you recover from the last section of the world and prepare for the next.

Growing up (if you’ll permit me to get a bit weirdly personal for a moment) I did a lot of camping and, especially as you get older and the world starts feeling a bit too big and a bit too small at the same time, there’s something liminal about sitting around a campfire with your friends. It’s easier to talk, it’s easier to reminisce and think. This is also true in Black Mountain – the characters are (through mostly but maybe not entirely their own faults) dealing with something much larger than they’ve had to deal with before, and only have each other to lean on. When they stop at a campfire, they might have something to say.

Technically speaking, the way this works is that I have a bank of campfire scenes (built with the same scene definition stuff I described in the last post; the campfire area is actually just its own map, internally), and at any given time I can throw one on a queue of campfire scenes. Every time you rest at a campfire, it checks to see if anything’s queued up, and if there is, it will play it. At the moment, this is mostly used just to provide another scene every few campfires that you encounter, to give a good idea how it works, but the idea is that if anything in particular happens, the next time you rest the characters might have something to say about it. I’ve thought about adding something the first time a character is knocked out in combat, for instance, or it could be used to add some reflection on the part of the characters after they’ve done something big.

The important part here is that it gives a little bit of space for the characters to talk about what’s going on, and give the player a bit more insight into what’s actually going on in their heads. I want to focus on making the characters relatable, and hopefully this will go a long way to doing that.

Back to Talking

I have been in a bit of a self-imposed hermit state for a while now, trying to grind out the main core features of the game (and also on helping with the demo for Alice is Dead, a remake of the classic Flash game, that’s in the Steam Next Fest! You should go check it out!). I’m in a spot now, though, where I need to return a bit to the world of the living, and so I’m going to try to start talking more about my game and what I’m up to, and that sort of thing! At a bare minimum, I’m going to try to get back on that Gruedorf horse and start posting here on a weekly basis again.

Cheers!

There’s a lot to talk about, so this is a long one; it’s been a while. I left my full time job (which I’d been at for more than a decade) in mid February, and while I’m not exactly sure what my time looks like in the long term, for now I’m taking a break and focusing on my own stuff for a little while. This means the last couple of weeks has been particularly full of development, I just hadn’t gotten around to writing anything.

Other Games

I released a game I wrote years ago on Itch. It’s called “The House”.

You can play it in your browser.

It’s a “Halloween game” – it’s not particularly scary or anything but it is, I guess, “mildly unsettling”? I started this back in 2015, and had most of it done some time around Christmas. Since I had missed any useful window for releasing it, I think I got my mom to play it and didn’t bother to release it more widely than that. (That’s not a joke.) It’s also built in probably the dumbest possible way to build an IF game in a browser.

I also spent a week or so building (in a somewhat less stupid way?) a nostalgic love letter to a 1979 game called The Wizard’s Castle (and a handful of other names over the years) – I call my version “Zot”.

I played a lot of an MBASIC port of the game when I was a kid, on a computer slightly older than me. I’ve actually remade it before, as some hard drive spelunking recently reminded me, but I figured it’d be quick to remake and the old version was for DOS.

Anyway, it’s not done, and I decided to stop using it as a reason to procrastinate on getting back into Black Mountain. I might still pick at it every now and then, but it’s not my focus. When/if I finish it, I’ll probably release it for free on Itch like The House.

Debugging UI

The game is pretty big now, and I’m not just working linearly through a bunch of maps, so I decided I needed some more debugging/“cheat” controls within the game. It’s pretty easy to bash together a UI in Godot as long as you don’t actually care much about how it looks, so I just did that. It even has a tabbed interface and everything.

The first tab is the flag manager. Internally, the game just has a big table of key-value pairs that can get set and checked (in code or in cutscenes), which automatically gets persisted through save game files. Not exactly ground-breaking stuff, but it works. All this panel does is give me a way to edit/create flags so I can bump around where exactly I am in the story or whatever, so I can re-trigger an event that I just ran or test different branches easily, that sort of thing.

The second tab is for jumping to a different map. One thing I’ve always despised in building a 2d RPG is having to carefully figure out an exact coordinate to drop the player on when they switch maps, and then put that coordinate in the map switch call. If you change the structure of a map, you have to go and find all the references to it in all the other maps’ code (or wherever those live), and change them. Instead I opted to put simple invisible nodes, “entrances”, and when you send a player to a map, you send them to an entrance instead – the player’s entity inherits the position, facing direction, and layer parentage of the entrance. It also makes it convenient to query and list all of the possible entrances to a map, which is what this list gives me. I can open the “accordion” for any map in the game and click an entrance, and it triggers a map switch to that entrance. Handy for hopping around to test different things.

(I should say that TECHNICALLY you can still send the player to a specific coordinate on a map rather than an entrance, but it’s a lot less convenient and I mostly only use it for internal stuff like loading games.)

I’m thinking about adding another tab with all available cutscenes and letting me trigger them, but that’s a little trickier. Not technically, but being able to trigger a cutscene anywhere you want would be a bit wonky since they will, by their nature, be written to work on a particular map and at a particular location. Might be worth it anyway; it’s just debugging stuff, after all.

Cutscenes

Black Mountain is a fundamentally story-driven game. One thing that I have always found both interesting and frustrating to work out is a good way to define a cutscene. In this case, I’m using “cutscene” in a pretty general way – anything where the player is not engaged in moment-to-moment decisions or direct control. In particular, I’m always striving for some particular things:

• I want a good way to be able to have as little boilerplate as possible in my cutscene definitions. I find it hard to write interesting scenes and program at the same time. Yeah, I won’t be able to completely get away without any “code” whatsoever, but I want it to fit as naturally into the writing as possible.
• I want to easily be able to set up things that do not complete immediately and wait for them. Something as simple as making a sprite walk a couple of tiles before popping up the next textbox can be surprisingly annoying to do, and often requires a lot of boilerplate (which I don’t want).
• I want to be able to do multiple things at once. Even worse than waiting for one thing is waiting for multiple things, especially when those aren’t trivial “things”.

I don’t know if I’ve necessarily built the best thing to handle all of this, but I do like what I’ve made. (I do wish I had encountered Dialogic earlier – if you yourself want to solve these problems, I suggest checking it out instead. It might work for you, and be a lot less work than what I did!) What I’ve ended up with is essentially a Domain Specific Language (DSL), which lets me load any number of .txt files, parse them at load time into an array of objects (that are essentially opcodes with arguments), and then trigger them whenever I want, by name.

The .txt files look something like this:

# Lines that start with a # sign are comments. I haven't bothered to implement comments that
# start some time later in the line, largely so I don't have to worry about escaping #s if I
# decide to use them in dialog or something.
    # Note that whitespace at the beginning of a line is ignored in all cases, so indenting
    # comments, or any other piece of the script to help with readability, is fine. Similarly,
    # blank lines are simply ignored, so you can space things out if you need to.

# A line that starts with a $ starts a scene; I'll use this name in an event to run this
# cutscene.

$ Scene Name
    - A dash shows a text box with no "speaker" defined, for narration or whatever.
    <Kiel> This is a dialog box, using Kiel's name and her portrait (if available.)
    > This would be a continuation of the previous dialog box, after the player hit a button.
    
    <Violet:sad> I can have variants of portraits; in this case the ":sad" will get stripped off and Violet's name displayed.
    > If there is a "sad" variant of Violet's portrait, it will get used.
    > If there is no "sad" variant, it will fall back on Violet's default portrait.

    <Some_Guy> For technical reasons, names can't have spaces, so I convert _ in a name to a space for display.
    > Also if there is no portrait for someone, it'll still show a name for the speaker but no portrait.

# A single file can contain as many scenes as you want; being able to load multiple files is just
# for convenience and organization.

$ Some Other Scene
    # ...

In addition to showing text boxes, I can…

• move entities (including the player and the camera) around the map (including walking around, changing movement speed, facing different directions, teleporting them to another location, switching maps, etc.)
• add temporary “puppet” entities to the map, with a specific name, that get removed at the end of the cutscene
• add and remove characters from the party
• play sound effects or change the music
• give items to the player and change character equipment
• start a combat
• set story flags
• branch based on flags (as described above in the debug UI stuff)
• run multiple chunks of script in parallel, waiting on all of them to finish before moving on
• etc.

There are some bits of functionality I know I’ll need that I haven’t thrown in there yet, but it’s pretty robust at this point. A couple of future things I want to do is be able to load different cutscene files based on the current language/locale being used, and also be able to compile the .txt files into .gd files that simply define the cutscenes directly in the object/opcode form – it’s very convenient right NOW to be loading text files but I don’t really want to parse those unnecessarily every single time the game launches. You can see a lot of this in action in this video of the first 5 minutes (moreorless) of the game:

https://www.youtube.com/watch?v=WhcVz3jEuw8

(Note that the music is currently placeholder – it’s public domain stuff found on OpenGameArt by the fantastic Juhani Junkala/Subspace Audio.)

Let’s Fight

With the beginning cutscenes blocked out, it was time to start tackling the next thing – fixing up the combat system. You can see a bit of it in the video above, but it’s rougher than the rest of the game, and so I started working on that. I decided I wanted more space on the screen, so I needed to make some things smaller, and there’s a lot of cruft internally from the various iterations I’d gone through. Also, as funny as that monster graphic is (to me), I was getting awfully sick of looking at it.

I was originally going to have a “heart” based health system rather than a more traditional HP system, but I decided to ditch that. The energy system was also going to be somewhat different but I realized some systemic issues with it that led some of the overall game and dungeon design in directions I didn’t want, so it’s a little more standard now as well. The bar (still to be implemented) is an adrenaline gauge system similar to a fighting game, where more adrenaline can empower special attacks and/or change how the character fights at different levels. I also replaced the constantly-ticking active time battle system with a visible queue of actions – it’s actually pretty much the same system but instead of filling up meters as time passes, it just pre-calculates the next X turns, so you can see when each character will be acting.

There’s still lots to do, but it’s coming together.

Wandering Monsters

I have a class of objects that I call “behaviors”. They’re nodes, or areas, or whatever, that you just drop into an entity on the map. Then, when the entity is being processed each frame, those behaviors get a chance to control the entity (in the order that they’re in the scene tree as children to the entity). Previously, I had three available behaviours: “look around”, “chase”, and “fight touch”.

• Look around simply stands in place and randomly changes direction. This is actually changing the facing of the sprite, so the entity is visibly “looking around”. It also doesn’t just pick a new direction and snap there, it will interpolate to the new direction over time.
• Chase adds a vision “cone” to the entity, and if the player enters that cone then the entity starts chasing the player. Almost, anyway – the behavior actually checks to see if there are any walls or other obstructions between the two, and will ignore the player if the sight is blocked. If the player gets out of sight (either by escaping the vision cone or ducking behind a wall), the entity will continue to the location it last saw the player, and then look around. If it has lost sight of the player completely, it gives up and stops chasing them.
• Fight touch just means that if the entity touches the player, it launches a combat. The behavior has the set up of which monsters at what position on teh battle screen.

Using these, and the fact that the behaviors will attempt to execute in a particular order, means that I can naturally express “fight the player if I’m touching them, chase them if I see them, and just look around if I don’t” just by dropping nodes into the entity. Also, changing the children (or just the order) in response to some other event means they could change what they’re doing based on whatever.

Anyway, so I also added a new behaviour, wander. The wander behavior needs to have a reference to a special “territory” polygon, and then the creature will simply pick a random location in the territory and, assuming it’s actually able to stand there, it will beeline straight for it. Once it arrives, it will immediately pick a new target location. This leads to my monsters sprinting around their territory in a frenzy, and also there’s no path finding or accounting for complex shapes, so it definitely needs work, but! This means that by dropping in a wander behavior instead of the “look around” behavior, I have monsters that will wander around, chase you if they see you, and attack. It’s another system that I’m pretty happy with how it’s turning out to be flexible and sensible as I work with it.

And then…

Anyway, so I’m spending a lot more time on Black Mountain these days than I was. Hopefully that keeps up! I’ll try to get back into this but we all know that the surest way to kill a blog of any sort is end every post with “I’ll post again soon!” If it comes down to it, I’ll always choose putting time into the game over posting a devlog… but maybe I can find a bit more of a balance, at least?

Have a good week.

• Drew a bunch more interiors
• Did a bit of a style test on a sprite

The last week has been pretty productive in terms of “work done” but honestly not a lot interesting to talk about.

Interiors

I finished the remainder of the story-important interior maps (assuming I don’t realize I missed some).

As you can probably see, these little homes are mostly built out of reusable pieces. This is because I got tired of drawing maps in the least efficient way possible! I’ve been experimenting with my scatter system to see how far I can push it and, in a pleasing turn of events, the answer seems to be “pretty far”. As an example, the smaller chairs visible in the various houses are all actually a single type of “scatter” as far as my tools are concerned, but you’re able to set the frame you want and flip the sprite, so they’re pretty convenient for bashing together a map quickly.

A Sprite

Quite some time ago I was trying out a sprite style for Geas and I drew a sprite of Kiel; just a single frame, sadly. I happened to run across it the other day and remembered how much I liked it.

Unfortunately this is made for a different resolution than I’m targeting with Black Mountain; it’s built for a 32-pixel tile (which would be about right for a 480p resolution). For Black Mountain I’m using a 24 pixel tile (because that fits a 360p resolution, which I’m using because it upscales to actual widescreen HD resolutions properly). The design is also wrong for Black Mountain; it’s an older Kiel who has gotten somewhat more confident and past her awkward teenage years.

So anyway I sat down to try to recreate a similar style, but for the smaller tile size and the right design.

I’ll probably still go back in and mess with it some, and then of course there’s the whole problem of it still only being a single still frame, but I’m glad I did it. It’s nice to remind myself occasionally that the game isn’t just going to be a sketchy red mess forever.

So What Now?

With the maps above complete, I am done the bulk of the (story-necessary) map making for the game. I’ve got two big projects left on this version of the game: Fill in the “game” bits, like puzzles and combats, and fill in the story. (After that, of course, I have the general “clean up and make sure everything’s in that I need in”.) I’m sure that I’ll need to tweak the maps as I go somewhat, but I’m hoping that won’t be too difficult. The danger with the way I’ve been building these maps, of course, is that if I need to substantially change a map’s structure I have to go back to Clip Studio and start moving things around – as I’m sure I’ve rambled about in the past, this is why I’m doing the whole “sketch” version of the game. Especially as I’ve been trying to switch to building more maps out of reusable pieces, this should hopefully not be too big a deal. So this time next week I will probably be griping about how my cutscene system has bitrot or something.

Have a good week!

• Neglected to post a devlog for a month
• Completed an interior area
• Reworked some level flows

Happy 2022, everyone!

The last month has been kind of hectic, and I was sick for some of it (no, not with that). I’ve managed to make some progress but haven’t gotten around to writing about it.

The Second Floor

The second floor of Black Mountain (which I mentioned a few months ago) is an abandoned town carved out of the rock. When pilgrims journeyed to visit the phoenix that lives atop the mountain, they would stay here. Unfortunately, like the rest of the interior, it has fallen into ruin and is now empty.

Or is it!? (It wouldn’t be a very interesting area if it was empty so you can probably guess that it is not.)

Some Miscellaneous Code Fixing

Since I am, fundamentally, much more of a programmer than an artist, I sometimes try to sort of side-step into getting some work done by tackling a small code issue or whatever. I’ve done that a few times, so my Entity Palette works a lot better now. I was having a lot of trouble getting Godot to actually generate preview thumbnails for the placeable scenes, so I read a lot about Viewports and the like and I’m now simply instantiating a little copy of the scene into the toolbar. It then also does some scanning of the scene to figure out how to automatically scale things so they fit into the “button” properly.

Getting the math right on the scaling was surprisingly challenging! Not because it was especially difficult, but my brain had temporarily stopped working, as it does.

Scatter Was Worth It!

Adding the “scatter” objects that I talked about in my last post was completely worth it. Much of the “dressing” of the rooms in the screenshot are, in fact, scatter, and while the bits themselves need some work, the workflow with them has been great, and it’s freeing me from having to hand-draw a ton of rocks, which I’ve gotten pretty sick of drawing.

Unfortunately, there’s not a ton more to talk about despite the long period between posts. Working on these maps is time-consuming, but I don’t want to show everything off. I’ll have to work even harder to figure this out when I get to actually filling things in with story. That sounds like a problem for later-Kildorf, though!

Anyway, hopefully I’ll be back in a week. Have a good one!

Gruedorf Post 2021-12-05

• Finished building a multilevel cave
• Added a “scatter” type

I couldn’t devote quite as much time to Black Mountain this week, but I still made some decent progress.

A New Cave

I have drawn most of the maps in roughly “chronological order” in terms of the order that the player encounters them. There is one particular cave (which you use to bypass a roadblock) which I just kind of… skipped when I was drawing maps earlier. Not entirely sure why, but it’s wired up now.

Scatter

And in making ths cave I just… could not bring myself to draw millions of rocks again. One thing that is a drawback of the way I’m doing maps is that it’s not like I can just play around with tiles until a cave looks as messy as I want; I have to draw each thing individually or go through some extra effort to set them up as entities. Entities are, internally, KinematicBody2Ds with their own collision information, they can move around, they have the potential to react to being “activated” by the player, etc, and I don’t really want to have hundreds of them in a map (even if, really, at least on PCs it probably won’t make that much difference).

Worse, since most rocks are tall enough to occlude the player character, I often have to draw each of those rocks in two pieces – behind and in front of the player. They also must be at least a whole tile wide or else you just can’t do that split correctly. This is also why I can’t really just toss them into the tileset. Trees also have this problem, but they’re big enough that they naturally split into a “stump” and the trunk/foliage. It’s kind of annoying to place two tiles per tree, but hey, it’s way better than the days when a tree was like 25 individual tiles on different layers!

Anyway, I decided to go ahead and add a new kind of thing; I only really need the art, they don’t need to move or have their own built-in collision or anything, but they do need some offset information and I want them to be easy to reuse. I called them “scatter”, which is a term I cribbed from tabletop miniatures. They’re the random crates and barrels and other junk that you can just kinda toss around the map to make a room look lived in. I had previously updated my entity palette (which I wrote about earlier) to allow for multiple sections based on subdirectories of my entities directory, so I just threw in special casing for a “scatter” subdirectory.

When you drag a scatter piece into the map, it finds (or creates, if necessary) a YSort node within the existing sprites YSort. I didn’t have to put them in their own subnode, but it keeps my scene tree a lot more manageable, since I can collapse that section.

I’m actually really happy with it. I’ve dressed up the cave pretty well with some boulders and some stalagmites, and it was significantly less work than drawing that all bespoke.

Miscellaneous Notes

• Remember that if a YSort node is a child to another YSort node, they will sort their children together.
• Godot allows you to enter a formula in its UI edit boxes – if you have a rect and you just want to move it to the right by 3 tiles, each 24 pixels wide, you can just edit its X member and write, e.g. 240+3*24 and it will convert to 312 for you.

That’s it for now. Next I’m going to be rearranging some of the Black Mountain maps a bit. I realized that I need to reorder the flow of the 2nd and 3rd level of the mountain to introduce doors and keys in a better order. Along with that I’ll need to actually draw some interiors (which I feel like I’ve mentioned every post for the last three months). See you next week!

• Got back to work on Black Mountain
• Imported all of the maps I’d drawn but not gotten into the game yet
• Fixed up some stuff I just hadn’t finished
• Some code refactoring
• Started drawing another cave

I had a week off so I got quite a lot done this week, and it wasn’t JUST playing Heretic.

Importing Maps

I had a big backlog of maps that were drawn but weren’t functional in the game yet. I sat down and got those all in. It’s semi-rewarding to do but still just kind of monotonous. You can now (I think) walk from the beginning of the game to the end! There’s no story in there yet though, just the maps, and some of the bits which are going to be light puzzles just let you walk through instead.

A Second Look

It also let me see that I just kind of… had stopped halfway through some of the maps. It also let me take another look at the flow of the maps – I’ve corrected one pretty layout issue and have some thoughts about fixing some others. I’m not super proficient at map design, so it’s something I’m trying to keep an eye out for. It also gave me the opportunity to try out the flow of re-organizing a map in this “drafting” format. It’s… okay. It’s certainly not as easy as changing around a traditional tile map. I don’t think I’ll change my mind about how I’m building the maps for this game, but it’s interesting to see what works well and what doesn’t.

I also came up with some ideas for how to make building the levels a little less onerous. I’ll talk about that more when/if I get around to doing it.

Code Refactoring

I’m trying to apply bits and pieces of what I learned from making six games in the last month to clean up some of the code. All things considered, I’m still relatively new at using Godot, and still firmly in that awkward phase where it takes way longer to make anything (big) than it takes to get better enough that you develop a pretty hardcore disdain for the code.

Happily (?) I intend to leverage this code for other games so it’s worth spending some time cleaning it up. The biggest thing I did was just small housekeeping things.

• I was inheriting from Node for a lot of helper objects that should have just inherited from Object. If it doesn’t need to go in the scene tree, it doesn’t need to inherit from Node.
• I was registering a lot of things as custom types unnecessarily, with the primary goal of being able to refer to them by class name. You can just use class_name for that – class_name Foo will make Foo available globally as a reference to that class.

I’d like to take a crack at making my movement system better, maybe. First I need to figure out whether I had a good reason for some of the decisions that I don’t like now. I also want to try to iron out some wrinkles in some of my basic map primitives, especially cliffs and climbable areas.

A New Cave

I have one cave that I need (you have to move through it to get through an area) to draw, that I just hadn’t yet, so I finally got started on that.

Some Pictures

It’s been a while since I’ve posted any screenshots from Black Mountain so here we go. The maps are not “finished”, they’re missing bits and pieces like trees, etc.

Gruedorf Post 2021-11-21

• Built a 2d block-pushing game with mediocre puzzles

Grab the Gems

You can play Grab the Gems online. – at least in theory. As I’m writing this my webhost seems to be having issues so if it doesn’t seem to be loading very fast, try again later I guess!

Grab the Gems is the name of a number of games I’ve made in the past. I come back to it and make “a new version” every now and then, usually as a way to try out a new programming environment or tool. I might come back and revisit this one some day because there is actually a certain amount of (very dumb) “lore” that I did not include in this game at all.

This particular version of the game is based heavily around simply Sokoban-style block pushing puzzles. Every level has a door that needs to be opened by pressing down a switch, usually with a block. Blocks that fall in the lava turn into platforms you can walk on. There are, in fact, gems to grab, but there isn’t… actually any particular point to getting them.

But Why?

So if I didn’t get around to adding in that stuff, why did I make it? Especially when it took two weeks!?

Well, first of all, you’re not the boss of me. I’ve been kind of exhausted and needed to pull back a bit on this stuff to keep from burning myself out too much.

Second of all, I specifically chose it to learn more about two areas of Godot that I want to get better at: controlling asynchronous behaviour and building editor tools, so I focused on those instead.

Asynchronous Behaviour

The original Grab the Gems was “turn-based” in the sense that it was a QuickBasic game where nothing happened at all until you pressed a key. So far, most of the Godot work I’ve done has been with real-time stuff, and I wanted a simple-ish game to dig into to try and nail a turn-based loop. It SEEMS like it should be easy, but it turns out that the standard way of doing things in Godot leans very heavily into these real-time systems. Even in a more fluid movement/real time game, I want to have a better understanding of event loops and such because I’ll need them for things like cutscenes and textboxes.

I already have some of this stuff kind of worked out for Black Mountain but it’s always felt a bit hacky and hand-wavey. I was hoping to figure out a more solid way of doing it! I had perhaps moderate success. I feel like I’m coming to a better understanding of it, mostly, but I still don’t feel like I know how to update the systems in Black Mountain appropriately to make things more controlled and predictable. I’m sure I’ll figure it out, though.

Editor Tools

Since I kept talking about it, I decided to use this as an excuse to try building some tools and then actually use them.

One of the problems that I’ve had a number of times in making these games is getting things in the right place in the scene hierarchy. In this case, all of the “entities” in the level (the player, blocks, switches, gems, etc) all live in a YSort node (called “Entities”) sandwiched between under and over tilemaps.

Standard Godot UI gives you a file explorer. As you can see I’ve got all of my Entity .tscn files tucked into a scene/entity directory. I can grab any of those .tscn files and drag them into the currently edited scene to place one of those entities. That’s all well and good, but it will create the entity as a child of whatever node you happen to have currently selected. I want them all to land under Entities, but if I happened to just be dragging around “Gem” to reposition it and forget to click on Entities in the scene tree again, if I drag another Gem.tscn onto the map, it’ll become a child of “Gem”. That will look correct, and might even work most of the time, but I don’t want to just have my nodes strewn all over the place willy-nilly.

It’s also a bit of a pain, because I want to grab the .tscn files, not the .gd files. Yeah, I could put the script files in a different location than the scene files, but I prefer this layout.

So I set out to make myself a palette of entities that will just always drop them into the right place.

And I did. Getting it working probably took half of the total development time, in the end, but it DID actually make creating levels faster. It was 100% not actually worth it for this project, since I only bothered to make three levels, but it’s definitely something I’m going to be cribbing in the future for other projects. The code isn’t quite just drop-in and it works, but it shouldn’t be hard to rework as needed. So that’s cool!

The basic parts of it are:

• Create a new plugin
  • Plugins are very cool but plugin development is a pain in the ass. I had to frequently reload the editor, since an error in some code might lead to having UI panels left over that I can’t ever clean up.
  • Another annoying thing is that when you change the code of a loaded plugin, it appears to reinitialize all your member variables but it doesn’t re-run _ready() and so on. If you have a saved reference to something, it just throws it away, and now you get a bunch of errors.
  • It is incredibly obnoxious that Godot’s editor doesn’t save your window size and position. I am using a single large 4k monitor, and Godot really wants you to use it maximized. There are apparently workarounds you can set up with a plugin, so I’m going to look more into that, but it’s offensive that I have to.
• Instance some UI and add it to the docks
• Add a refresh button
  • This saved me from SOME reloading at least.
• Get a list of all the .tscn files in the scene/entity directory
• Generate a preview of each one
  • Previews are built into Godot! Accessing them is awful. You must have access to the (global but NOT singleton) EditorInterface object to get access to the (global but NOT singleton) ResourcePreviewer object, but you can ONLY get the EditorInterface in the actual EditorPlugin class, NOT in the UI scenes that it instances.
  • I used a disgusting hack to get around this – since the EditorInterface is global for all EditorPlugin objects, I just instantiate a new EditorPlugin and get it from there. This trick is documented in Godot Q&A but it is another thing that is offensive to me.
  • Also worth noting that once you DO get the ResourcePreviewer, you can call queue_resource_preview() on it – this takes a path, an object and function to callback to once it has the preview ready, and a “userdata” for you to pass info through. It turns out that queue_resource_preview() will not actually call that callback, if you pass null as the userdata. Pass 0 instead.
• Add drag and drop to preview buttons
  • This was surprisingly not too bad, but I didn’t bother to use the built-in drag interface. I just used button down and button up signals on TextureButton controls.
• Make UndoRedo work
  • This was kind of annoying to get right. You’ve got to supply both “do” and “undo” functions, and in this case since I was instancing a new version of the packed scene, I needed to make sure the lifetime on the instance was right. Instead of calling queue_free() on it for undo, you just want to remove it. Instead, instance the scene before you set up the do/undo methods, and use add_do_reference(instanced_scene); that way it’ll be around for redo to add it back to the scene, but it’ll get cleaned up it falls out of the UndoRedo history.

I’m probably forgetting some pieces. Like I said, it was probably the hardest part of this whole project. It’s very nice to have it working, though, so it may just be some pain I have to put up with, in order to have a nicer time of building the rest of the game.

Have a good week!

• Messed around with tool scripts and plugins to get a better feel for them
• Built a blocky first person shooter

Castle Escape 3D!

I have harnessed what was previously only hypothetical: a THIRD dimension for video games. You can play the result, Castle Escape 3D, online.

Tooling

I actually wasn’t going to make a game at all this week. I figured since I’d made 4 in the last two weeks, I could take a breather for the week and instead delve into looking at building tools for Godot. I messed around a bit, figured out how to add novel UI to the editor, and then felt the itch to just make a game instead. I still learned quite a bit, and realized that I had been using plugins/addons incorrectly for Black Mountain. So, toss that on the pile of things I need to clean up when I get back to it.

Escape the Castle

I was a kid at just the right time for Wolfenstein 3d and Doom to be a huge deal. We also had the shareware version of a lesser-known cousin to those games, Catacomb Abyss, which captured my imagination – look, I’ve been a Tolkien nerd since before I could read – in a way that nazis and sci-fi demons didn’t quite manage. It certainly isn’t a better game, but I do love fantasy shooters, and I feel like they’ve always been an underserved market.

Anyway, so I had the 3d Catacomb games in mind a lot while I was building this game. I decided that, for the sake of speed, I would build the levels (which, in the end, was only one level) out of blocks, just like that era of game. I actually re-used some of the tiles I drew for the platformer a few updates ago, but drew lots of new art as well, probably more than I should have. The hand (based on a photo ref on my own hand outstretched toward my computer monitor) is probably some of the best work I’ve done for these games so far.

I ran into a few hiccups. In no particular order…

The HTML export didn’t work out as well with this game. It’s been great with the 2d games, but this one seems to have a bit of hitching that isn’t present when running on the desktop, and there were some texture glitches. Nothing game-breaking, but unfortunate. I also didn’t actually spend any time trying to troubleshoot those, so maybe it would be easy to fix.

Importing textures in 3d defaults to importing them in “Video RAM” format, and filtered. This probably makes a lot more sense when you’re not using pixel art for textures. The real lesson here is, if you’re going to be importing a lot of art that matches in style, use the “Set As Default for X” feature (under the Preset menu in the Import tab). Don’t just keep redoing it manually like a dumbass when you’re trying to build a game in two days.

GridMap is the “3d tile map” primitive that Godot offers. It’s actually really cool in a lot of ways but in a few specific ways it is not so cool. Its UI is kinda bad; in particular, its tile selector does not show you tile IDs anywhere, even though their integer ID is the only way that the rest of your game is going to be able to refer to them.

Similarly, it’s really cool that you can set up a scene with a bunch of meshes and some collision data, etc, and then import that as your MeshLibrary (“tileset”) for use with GridMap. What is less cool is that it centers every one of those meshes, even if they are not supposed to centered in their grid space. If you double-click the MeshLibrary .tres file after the conversion, you can manually modify the offset for the each mesh – but next time you create the MeshLibrary by converting your scene, it will throw that away. Also, if you rename one of the meshes in the source scene, it will not get rid of the one from before and will instead just add a duplicate with a different name. (It’s possible you could leverage this second bad behaviour to work around the first? It’s annoying that you have to, though.)

I use billboarded sprites a fair bit in this game. It took a while to get the rendering just right, and it turns out that you probably want bill boarding turned on (I used y-locked bill boarding throughout this game, I just prefer it) and you also want to set the Depth Draw Method to “Opaque Pre-Pass”.

And So On

Not sure what I’ll work on next. Maybe I’ll actually take a week off from making games? Maybe I’ll actually make something smaller and easier like I keep intending to, rather that making something more complex each week? Who knows. Have a good one!
