Side Project progress

I decided to spend more time making art instead of getting the proc gen all figured out, so I also made some item art:

Basically went a little bit overboard making random items, trying to have a variety of variants for each item. I do get that I could just do palette swapping or other shader tactics to get different colors, but I decided not to do that for now, this way all color variants are strictly using the dawnbringer 32 palette.

I also did some additional outdoor tileset art, but not much new since last post.

Proc gen

Not much progress to report on the proc gen front this time, trying to wrap my head around how to actually do the logic, it seems like it will be much slowly to generate than the wang tiles just because there are a lot of arbitrary things like “find the cell in the tilemap with the least amount of possible tiles” and stuff like that, which look like it’ll be a mess of looping through things, which is just making the generation time look insane.

I may mitigate some of that by trying to store a list of all the cells that haven’t had a tile put in yet, at least to prevent having to loop through all XxY cells in the tilemap for every iteration through, and instead just pick from the ones remaining. I’m trying not to think of the big o of whatever the result I end up with will be.

other stuff

I’ve tossed the idea around a little bit too of trying to learn Rust in some way, but not really wanting to add yet another side project, so I’ve been putting that off for now, but I may wind up pausing this side project for that side project, or similar, not really trying to write two engines, one in C++ and one in Rust, but maybe if I used the Rust engine to target DOS or something else like that? Who knows.

That’s all for now.

[Coolcoder360]

And back to the Engine!

Got back to doing UI work on my engine, labels and buttons are now possible to be put into windows. They do overlap in the screenshot here, but I’m not sure I care for now, it’s working!
And the button even works (just logging stuff for now when pressed, but still, that’s progress!)

However there are cases now where I’ve noticed some odd/unreliable segfaulting, some involving EnTT type assertions and such, so I’m a little bit concerned about the reliability/stability. Again. But progress has been made. And good progress at that, I mean what more do you need for an editor than buttons and labels? Okay Text Input is a good next thing, and then checkboxes and radio buttons are probably also going to be on the list, maybe sliders too. But baby steps for now.

Other side projects

In other news I’ve started a little Rust project with SDL2 just for like, learning Rust and such.

I’ve also started making a Pixel Font.

And I’m still doing pixel art for my Godot jrpg procedural map generation side project.

Next steps

I think next steps are going to be

1. Add text input boxes
2. Add checkboxes
3. add radio buttons
4. try to fix up the reliability a little bit to make it more reliable

That’s all for now!

[Coolcoder360]

So I had my brother-in-law visiting for the past couple weeks, and he’s young and excited about game making, so I did what everyone does. started a new project with him to work on.
Just a godot project, don’t really have much on it to be honest, but maybe it’ll get there, that or it’ll just sit as another unfinished project.
Him being over distracted me from most of my other projects.

Engine progress has been pretty quiet.

I do however have quite the development at work, so I’m going to need to step up my note taking and organizing game. I prefer to handwrite my notes on paper, since that helps me both to remember what I wrote, and let’s me take notes off to the side while I’m presenting, sharing, or typing something else on my computer.

This does mean a couple things though:

1. My notes aren’t easy to search or sort
2. my handwriting is horrendous, so being able to read my own writing is sometimes difficult, or nigh impossible
3. if I want to convert it to text, then most standard out of box OCR things I would expect to not work very well.

I did look into something I’d heard of a bit called Rocketbook, as this looks to be the least expensive type of “smart notebook” starting at only about $34, and you get a notebook with sheets that can be erased with water as long as you use the special pens.
The issue, is their app’s OCR involves sending the scans to their servers, which in my mind is kind of a no-go. I want something that I know doesn’t create any type of security/privacy issue with what I’m working on, and will let me potentially use the solution for both work and for non-work things.

So basically I started a new project to train some ML models to do OCR on my handwriting. I took a intro to machine learning/AI class a long long time ago, and I’ve dabbled about with tensorflow in a past so it’s not all super new to me, but OCR is a somewhat complex topic and has multiple moving parts, so I’m following along with a couple of tutorials.

The gist of it is that you have to do two things (typically with two different models)

1. Detect where the text is
   • this usually spits out a bounding rectangle of each chunk of text in the image so that it can send a cropped image of just the text to the second model
2. recognize what each chunk of text actually is
   • this is what does the actual handwriting

There are actually pre-trained models you can find to do both steps, in fact there’s already a project using said models on Android to do the recognition completely on a phone, however those models are trained on computer printed/generated text, not handwriting, so I doubt they will be very accurate.
So my plan is to basically find models to do those things, and then create some sample writing data myself, so that I can train the models on my own writing instead of someone else’s. This is good because sometimes my words turn into squiggles when going quickly, so if I can write crap out, and then type it out so I know what it says, then feed it to the model, in theory I should be able to get some semblance of a working OCR model off my own handwriting.

I would need to likely find and train a detection model, and a recognition model. I plan to do that on desktop using python + jupyter lab (an in browser python editor/tool which is fairly nifty for data processing and can display matplotlib graphs and charts inline with the code blocks)

After that I need to convert each model to a tensorflow lite model that can be loaded by an Android app to run the models on a phone, so I could basically make an app to take a picture of a piece of paper or notebook page, and then turn it all into text.

I also haven’t decided what should happen for the images, I do sometimes have diagrams, and formatting is also a fun challenge, so I may have the app take the images and save them separate from the text, and/or I might have the images get put into a PDF along with the OCRed text data.

For now I’m following along with this tutorial. it seems fairly in depth on how to do things with explaining the code as you go, and is an easy format to just copy/paste into a jupyter notebook. This is just the handwriting recognition portion, and not the detection portion though, so I will likely need to figure out how to locate the text in the picture/page with a different model.
I’ve been eyeing a model called EAST for that, it seems more aimed at detecting text in the world and not on a page, but really I think that will just improve the robustness of the model for what I want.

So I guess it’s off to collecting a few thousand word/writing samples from myself to train this puppy on, tune in next time to see how long this project lasted!

More non-engine stuff

Okay I get it, I get distracted a lot. but this time I installed a new distro, and started another project(s).

New distro installed

I got bored with Debian, and remembered I left like 1500GB on one of my hard drives to install other distros, so i installed the Garuda with i3wm. I think it looks pretty slick:

It’s supposed to be good for gaming, and debian wasn’t bad at gaming it worked quit well, but this is supposed to be more up to date than stable debian, so I figured I’d give it a shot.

It’s arch based so I’ll need to test it for some time before I recommend it, I didn’t have too many issues with Arch, I ran it for probably 5-6 years before I needed to do a reinstall. Compared to Arch, Garuda’s first time setup is super smooth, came with everything I needed to set up my bluetooth headset already installed out of the box, all I had to do was turn bluetooth on and pair. Which is better than debian or Archlinux, Arch is notorious for needing lots of configuration, which is justified. Debian I only needed to install bluez and the other bluetooth tools and then it worked plug+play after that, this simply came with it pre-installed right out of the installer.

New project again 1

I decided while playing with a new linux distro I should play with learning something new and practicing something old. I hadn’t done a straight C program in a while, so I’m working on learning ncurses and plan to make some sort of (potentially simple) text based game/thing with that.

new project again 2

Aaand I’m also back into Godot, looking at making some sort of VR project or something. not sure yet but figured I may as well now that I have my VR headset set up again.

Eventually I expect to get back to my game engine, but just playing with new projects for now.

[Coolcoder360]

I’m just gonna breeze in here this time and post that I made progress on adding a checkbox to my UI stuff for my game engine:

So that’s good, I can now have checkboxes! and each checkbox can have a label, can have the value be set/retrieved, etc.

The docs for Nuklear aren’t super precise on what specific ui widgets there are, and how to use them all, but i did find out that I think its also possible to get an “onClick” type action from it, so I’ll need to still set up bindings for that then I’ll be done with the checkbox.

So for now I have:

• labels
• Buttons
• windows
• “rows” which are basically a way to have a row of inputs in a window
• checkboxes

I think for a functional editor GUI I’ll still want/need at minimum:

• drop down menus
• textbox input
• radio buttons, possible I could just implement this with some horrible combination of logic and checkboxes
• scroll bars

And I think for a wishlist I would want but not require:

• file browser/picker/chooser
  • To let picking assets or script files
• color picker
  • to allow picking colors for things, this is mostly useless for now since I think my shaders don’t even support vertex colors or a blending/mixing color at all
• Sliders
  • gotta have these for anything that involves sliding, not sure I can think of an application in my MVP editor use case
• progress bars
• some sort of scene tree type deal

Progress is going slowly, but its progress on my main project nonetheless!
One thing I think I should probably do at some point is mock up what I want the editor to look like, since otherwise I could probably get stuck in GUI widget implementation hell, so having a MVP type thing would probably be good enough to get the workflow figured out to know when I can basically put a stop to implementing GUI items and get the editor GUI and functionality together

Really all that’s holding me back I think for now from having a “working” game is:

• No editor
• No ability to zip/package up data yet or “bake/package” it out

I think in theory it should be possible to have scripts that implement a basic game at this point but I just want to have an editor going first then do a game.
In all likelihood I could probably write up a basic breakout clone already that would mostly work.

[Coolcoder360]

Tada, new project. again.
This time I’m working on an arpg first person dungeon crawler maybe open world type game. Something in the vein of Ultima Underworld.
Something with a 3d first person view but with plenty of UI stuff chonked next to it, like this (from Ultima Underworld):

The way I see it, this screen has a few basic parts:

• a set of action buttons on the left
• the 3d first person view with a compass, some animated aligator/dragons and enemy health meter gargoyle face
• inventory and equipment menu with health meters and a toggle to show stats.
• a text log that let’s you read text of what you’re investigating or interacting with.

So I have a quick mock-up I threw together in Godot:

I’m not quite there yet, I’m still figuring out what screen resolution I like, aspect ratios, UI layout, etc etc.
But I have:

• Action buttons on the left
  • Look/examine
  • Interact
  • Talk/Speak
  • Attack
  • Save/Load (the quill works great if I have the caption next to it, I think a floppy disk looks better if there is not, maybe will reuse quill for a map/quest log)
• 3d viewport with first person view
• some type of tabbed GUI on the right for eventual inventory, stats tracking, health/mp/whatever
• bottom area I plan to also add a text log so I can have shitty programmer art that looks like garbage but can still determine what it is.

For now I actually don’t have mouselook at all, I decided to try to go “old school” and ripped out mouselook in favor of letting the user click around on things, and they can use WASD to move forward and back, strafe/side step left and right, and then Q to rotate left and E to rotate right. I think that works out slightly better to let the user click on/interact with specific things in a scene, and hopefully will give it more of an older school vibe.

One thing I don’t know if I"ll implement is that Ultima Underworld does implement turning if your mouse is near the edges of the 3d viewport, that might also be worthwhile to implement so I may do that too, we’ll see.

I think next order of business is figure out world loading, kind of the menu flow from main menu, gameplay, and basic player save/load, then I"ll work out the stats/combat, and inventory/equipment pieces.

I think in the end I want to implement basic dialogue, inventory, and maybe a quest system, along with a stat based arpg system setup.

For style I know I want it to have crunchy pixels and I picked out a few different palettes from Lospec, so I’m hoping that if I limit myself to the same few palettes it’ll look somewhat okay, but if not then I guess it’ll probably be fine. So far I have one palette picked out for UI stuff, and one that I"m using to draw up some equipment in libresprite.
Here is some of that equipment textures/sprites work I did:

I think it would be cool to model some of it in 3d and then just map pixel art onto it as textures, but I might also just go with 2d sprites for some of it. I think monsters/creatures makes sense to be 2d sprites but it might depend on what it is.

Engine progress again

I’m back at in on the UI stuff for my game engine.

My september jam didn’t get very far, will probably pick it up again at some point, but I’ve been distracted by VR stuff again, and interested in potentially making my engine have OpenXR support sooner than planned, but of course I’ll need a working editor first, so I’m working on the UI pieces.

I added a combo box and a Text box to my UI widgets, I’m still trying to figure some things for the text box, since for some reason it isn’t working, but the combo box operates well as a dropdown.

And here’s an example of the problem, using the same input callback, my own console that I rolled myself captures every character input, but for some reason the Nuklear UI textbox only gets every 3rd or 4th character, and its unreliable which it gets.

Once I have those widgets all working properly I think it’ll be time to get an actual editor of sorts together, get model loading going, and then get onto the level saving/loading and asset packaging pieces.

Oh and I just noticed that if I sit in the engine long enough, the stupid thing segfaults.
My other project was to learn Vulkan in Rust, which I just might pick up instead of this engine since I’m running into so many memory issues.
Like I have no problem debugging mem issues, but it sure seems like I might have a higher chance of making a working engine if I go that route instead of this. But that would be another complete rewrite, and I’ve been enjoying this iteration. Not sure I feel like completely re-writing and starting from scratch in Rust, so we’ll see.

[Coolcoder360]

Wow I’m trying to make a new gruedorf and it’s been so long that I got asked to make a new one because this topic was so old…

Decided from some discussion in the discord to do some smaller godot projects just to keep the creativity/learning/whatever going, rather than biting off a bigger project than I can chew and continuously starting new things (looking at my VR project I had).

So I made a very simple/basic Sokoban game in Godot. it’s not really finished but it has some of the basics. Blocks that move and can block the player (I used the physics system to move them, which is a bit troublesome/error prone for a sokoban, I’m thinking I should change that if I go to a full/proper version with this kind of concept.) And it had a winning screen, multiple levels, and a main menu, that’s it.

I also have gotten back into working on my engine a bit now, but I think I’ve come to the conclusion that I need to work on making it crash less as a priority, so I’m going to pause on the Nuklear UI under the assumption that it’s causing the crashing, I’m going to work on finishing the last render thread vs update thread splitting I needed to do to ensure nothing crashes there, and then I"m likely to implement my own UI components at least temporarily until I can either confirm that Nuklear is or isn’t crashing things, or figure out how to get Nuklear to not crash.

Fundamentally I have a mechanism right now to let entities with the right script setup to get text input for the console, so I just need to add a way for UI items to get click events, and then in theory I should be able to just implement UIs fully in lua scripts, with just rendering stuff via textures or other fun mechanisms. So I think that should be enough to let me cobble together a UI from lua if I can just have a way for the scripts to get mouse clicks and text inputs. The look of it may not be super flashy yet since I have no good way to really do animations at all, maybe I’d find a way to cobble together a button press animation for buttons, but for now I think making good UI is not on the top of my list, I just need to be able to make a UI, that way I can have an actual editor somehow. might be a bit funky as far as setup/usability goes but I have hopes that it’ll work out.

Really all I need an editor to be able to do for now is let me place objects at locations, modify those objects, attach scripts, and add other components.
Then also have some buttons to let me save out a scene and the data and then at some point figure out how to have it all get packaged up for an actual end game, and then figure out how to have the game play in editor.

[Coolcoder360]

Time again for another update I guess, not much to report but I’ve been doing some good rework to make just the Texture loading for now be able to happen on a different thread from the update thread or the rendering thread.

So for that I have a threadpool that I think I yoinked from somewhere, which let’s me basically queue up functions or lambdas to be executed in the pool of threads. I can also configure how many threads are going to be in the pool, which I currently have set to 3.

Then I also found I needed a way to reference the future Texture that will be spat back from the thread once it’s loaded, so obviously I looked at std::future.

And then found that std::future doesn’t currently have a way to check if the value is ready without waiting for it, that’s an std::future experimental feature, since the std::future valid (or shared_future, for what I would use this for) only checks if the future is a valid future, not if the value/data was set.

So i rolled my own templated Future Class to simply have a way to set or get data from it, as well as tell if the data has been set or not with an isReady().
This means now all my std::shared_ptr<Texture> will need to become std::shared_ptr<Future<Texture>> so that’s quite a bit of refactoring, which I think is mostly done now.

One gotcha with this though, is I didn’t want my Future’s getData() to return the value, since that would be a lot of copying, so now instead of being T getData() it’s T* getData(), but that means now I have to be careful that the Future doesn’t get decontructed when the data is still referenced somewhere. This is a real problem because right now the Texture data is being passed via standard pointer like this to the Render thread, so there is in fact a possibility of segfaulting here.

I’ll probably look into how to wrap that, maybe my Future will hold the Texture as a std::shared_ptr<Texture> itself and return a std::shared_ptr<Texture> from getData instead of Texture*, that would likely solve the issue because then the Future<Texture> only holds a reference to the Texture that will clean itself once all other references are destructed, so it can stay in memory until after the rendering thread is done with it and then once it’s cleared out of the Update thread and the Rendering thread it’ll delete itself instead of leaking or becoming an invalid pointer that is used in the Render Thread.

That’s the main scoop for now I think, good progress though since most of the errors of switching the TextureLoader to return std::shared_ptr<Future<Texture>> are cleared up now and the getResource functions for that will now toss a lambda into the threadpool. I think the jury is still out on whether or not it’ll all actually work but considering that I already use a similar mechanism to the threadpool for my workqueue stuff, which is actively used, I think the lambdas and threadpool and everything should work, it’s only a little issue with that getData() returning a raw pointer and not a shared pointer and hopefully that’ll mean that now I won’t be bogged down as much doing Texture Loading.

I’ll need to do a lot more of this in the future I think, although I realized that I may not need to do this to all of my types, but it’ll probably help for anything that is large enough since I suspect Disk reading all needs to be dumped to a different thread.
And uh, actually I just remembered I need to re-check what I put into the lambda, I need to make sure that the disk reading part is inside the lambda, I think I left it out in front of the lambda portion…

[Coolcoder360]

You know its bad when you’re asked to just start a new topic instead of replying on your old gruedorf thread…

Been busy with a ton of stuff lately, work, games, other work, relaxation, cooking…

But what I’ve gotten into recently, aside from another new raylib project trying to port OSRIC into a computer game, is looking at trying to self-host things.

It’s a confusing world but one of the things that I’ve kind of been wanting to do for a while is figure out a file sync system that I could host on my own machines/hardware and have the storage saved locally, with potential cloud backups.

I’ve been looking at options and services for a little bit now, from cloud hosting providers, cloud storage options, etc and I think I’m finally going to pull the trigger on this, I’ve got an old clunky 11+ year old laptop, and an old dell optiplex 3080 micro that I’ve ordered a power supply for. So that’s at least 2 computers, so I may as well try to do something with them before I get a rack server.

Browsing the self hosted Lemmy and I found that a lot of people mentioned this thing called ProxMox. This is basically a fancy enterprise level tool for administrating virtualized servers. It lets you have clusters of various machines all running the proxmox bare metal software (basically its Debian with extra steps I believe) and then you can get a fancy schmancy web gui that you can control things with:

It also will help install and manage Ceph on all the nodes in your proxmox cluster, which seems neat to me as I’m also interested in that sort of thing, basically letting you replicate data stored in a local “cloud”.

So far I haven’t done any containers or VMs with it but I think that’s the next step I want to do.
I’m hopeful to be able to host NextCloud as well so that I can basically have my own synced file storage on my own machine.

Whenever I need to reimage a machine or take backups, I find I tend to use google drive but I’m too cheap to pay for google drive, and so I have like two google accounts that are basically running out of storage. This way I could store all of the important stuff locally and then potentially back it all up to backblaze.

Anyway I guess I’m off to figure out how to run some containers in here and see if I can get docker+docker-compose working. if I can get those working in a container, I’ll be able to start hosting stuff like the Nextcloud, etc. Only weird thing there is I’ll be using containers inside of containers. Not sure if that’s necessary, but the containers are faster to run than VMs and I’m not sure if I want to need to go update+configure all the containers in proxmox directly, seems easier to have a docker compose file that defines the services and everything needed.

[Coolcoder360]

Well update on that, after like 3 days of struggling with nextcloud I’ve finally got that set up with working collabora-code
That let’s me have basically my own self-hosted “Google drive” or “Office 365” experience, so you can upload, sync, download, edit files online in my own self-hosted cloud.

That looks effectively like this, you have a main dashboard with apps along the top left (looks similar to like, all the office 365, Desire2Learn school or work hosted solutions doesn’t it?):

And then you can open up docx or other micro$oft files and edit them in browser, supposed can be done live with others as well (untested still, and I guess I must have issues with spellchecker right now…):

So next I’m going to be figuring out how to make sure my pivpn is set up so that these can be access remotely, I have them set up to be just HTTP instead of HTTPS since it wouldn’t work the other way.
This is my docker-compose file for it (saving here since I need to back it up now that its working, and it took 3 days to figure out):

version: '3'

    external: false

    ports:

    cap_add:
      - MKNOD

NOTE: don’t use this on anything publicly facing, I have HTTPS turned off, its “fine” here because I’m planning to only access it from via a VPN remotely, and not through the public internet.

Now that that’s all set up I need to make sure my wireguard can let remote machines use the pihole as the DNS server so I can get a locally defined domain to connect to the nextcloud.
Then its on to setting up a second proxmox node with SSD, migrating this to that, then reimaging the laptop with an SSD in place of the HDD. Got it a 512GB SSD for now, maybe up that at some point but I’m hoping to get a rack server as well at some point. Right now its at 600 GB HDD, so it’ll be a bit of a downgrade but I think SSD will be worth it.

Right now honestly the browsing of nextcloud isn’t too bad off a HDD.

In other news of my self-hosting adventure, I also set up gitea.
That was way easier and faster than Nextcloud and almost too easy.
That one I haven’t considered ready for production just yet, I’m waiting until I get the second machine up and then I’ll probably look into having gitea pull over all my private repos from gitlab. It looks like that is a thing at least.
I may have my gitlab stick around and maybe see if I can’t get gitea to mirror changes up to gitlab as well, so I can have a redundant backup of any code projects I want to have.

The one thing I want to make sure I can do is back up my crap out of these containers, since that right now seems non-trivial to figure out how I get just the files out of the volumes.
For now I am taking snapshots as necessary to basically save state on the containers, but of course having a way to get full backups out of just the files/data would be good, I don’t want to necessarily have a full image/backup of the machine that is running these things, I just want to have a way to get the file copies out of there and back it up somewhere, don’t really need to have the whole container image with it too.

[Coolcoder360]

Been a while since I did one of these, but I’ve certainly been busy with plenty of new projects.

Started a bevy+Rust project, trying to learn how to do Wave Function Collapse to do world gen for it, since its winding up to be mostly some sort of roguelike rpg type game.

I’ve been playing Shattered Pixel Dungeon on my phone, and Nethack again, so being a roguelike fits in with that pattern.

For the WFC I’ve never done it before, but I did do something similar to it that I called “Wang Tiles” if you scroll back a few years.
In that case I basically had pre-built hand crafted tiles with edge connectivity, so the algorithm had to follow the edge connectivity constraints in placing those tiles. That worked well enough, especially with using random walk to ensure cross level connectivity.

The way this WFC will be different, is that instead of hand crafting those tiles, I will simply be generating a sample level/world for it to sample from, then it will generate NxN tiles from that, which then it will figure out overlaps, and then map the tiles together.

A good example of that in the theory side is this article: https://www.gridbugs.org/wave-function-collapse/ It’s in rust as well, however I’ve noted that the code samples are not complete, so you can’t just crib it from there.

Specifically the problem I have is that none of these tutorials, descriptions, etc really say what the best data structure is to hold all of the tiles generated, as well as their connectivity.
That Rust example on gridbugs has tons of example Rust code, but just generalizes this part into adjacency_rules which is some struct with functions implemented on it that they don’t even cover or describe in the article.
And then the code in github is so large that I can’t make heads or tails of it to find the adjacency rules portion, and seems to be more of a library crate or tool to use to do wfc, and not so much a reference for building your own.

This other resource: https://www.boristhebrave.com/2020/04/13/wave-function-collapse-explained/ is quite a good description of the logic flow for basic WFC, but it seems to move cover the basic 1x1 tile WFC, and not the NxN WFC, which it refers to as “overlapped” WFC. In that case it has a very simple method for determining/tracking the possible neighbor tiles, using an array of booleans for each possible tile in that slot, anything true is part of the “domain” and is possible to be in that slot.

I’m attempting the NxN tile method, so its going to be a long process, I think first I need to generate all the NxN tiles as described int he gridbugs article, and then basically compute all the adjacency.
Then I think you’re supposed to do some entropy calculations and then use that to pick the next tile to place, and once you pick a tile to place you need to propagate down all the possible remaining tiles in the affected tiles, and its a whole freaking thing…

Going to be a long slog I think, and I don’t even have rendering set up yet to render out the tiles in any way shape or form…

I’d have started with 1x1 tiles but for what I want to do I’d need to have like, tons of tiles to hold every possible different wall tile in different angles or whatever, and I think at this rate its better to just represent walls as just Wall and then either use one sprite for all of them, or go in after the WFC happens and then map the tileset onto the tiles.
Plus this way the tiles generated as Wall will also be entirely collision, although that means no diagonals, but I think I’m okay with that…

New gruedorf time.

And another new project. Sort of.
Switching back to Godot for a bit, but I didn’t hit “New Project”! instead I opened an old project and now my new project is creating a Godot addon/plugin that automatically creates a controls menu which allows changing controls bindings.

The idea is to basically create tools I can reuse in future to implement basic things like controls menu rebinding, maybe settings menus or other such things.

So far what I have is basically a script that creates a menu list of all the actions that are configured in the inputmap for the project, and then shows an icon next to it for any mapped buttons:

Using the Kenney input prompt icons of course, has support for mouse+keyboard, Xbox, PS4, PS5, Switch, Steamdeck, playdate. That’s enough platforms for me for now I think.

So far I’m only dealing with keyboard inputs, I’ll need to play around with supporting mouse input and then controller input bindings.
Then I hope to make it so I can select and then choose a new input option, making it play nice with controllers and mouse+keyboard of course.
I’m also ignoring all the built-in actions right now that start with ui_ because there are a ton of those and they kind of clutter up the list. I’m thinking for right now that people usually don’t want to re-map the buttons that are used to navigate the menus or do text input, so I shouldn’t bother to let those be an option for now.

I’m also working on compiling Godot from source, once you have the dependencies its actually really easy to do, so that’s been good.
I found this Godot Build Options Generator which basically generates a custom.py file you can use to make your Godot builds be smaller and have unnecessary modules compiled out of them, for games that might not need all modules (like, if your game is entirely 2d, why bother with 3d file format import/export support, or even 3d support in general?)

May look into trying to make some Godot Modules myself or other plugins as needed, right now leaning towards plugins that can just be included as part of a project to help get basic building blocks like menus working faster, maybe other features like my own character controllers or similar things like that.

I do use other character controllers or other plugins from the assetlib from time to time but for some things like character controllers I like to make it myself so I know all the ins and outs of it and how to make it do what I want/need.

Then maybe I’ll get something put together for an actual game that uses all these plugins, since doing the plugins should make getting a game together faster if it’s just a matter of including all the different plugins to make the boring parts work.

Some more progress on my plugin, moving some stuff out to a singleton to provide a better API where a game script can call into and then retrieve the right icon for an action.

Also adding a little “tutorial” prompt sort of thing:

Displays at the bottom right and disappears (not fade, just pop-in and pop-out directly with no transition right now) after a few seconds.
Might change that up to tween up from bottom of the screen or something like that.
But seems useful to be able to provide a way to just call controls.popPrompt("move_forward") and then the little pop up will just go, built-in, with the only thing needed to do is map move_forward to a default key/control and then give a translation file for translating move_forward. Which I might change to say “Move Forward” rather than just “Forward”. Given this silly example which doesn’t seem to have correct/proper english.

Other than that I think things are going well with this, not doing full joystick detection yet to remap things, but I think it should be able to detect whether a joystick/controller is being used vs if a keyboard/mouse is used.
Then the trick is to add controller support to the methods getIcon(event) and getBestIcon(action) since the getIcon(event) takes an InputEvent to give an icon for (useful for the full remapping menu to have an icon for each event) and then the getBestIcon(action) would use the controller vs keyboard detection to show the right icon for that action based on which input they’re using, hopefully specific to their controller (which right now I’m not trying to detect too much, I have only 8bitdo controllers so I can’t really test this out too much).

Once this is all together then I guess it’s a matter of making an game’s menu where the controls remapping menu would go, then adding ability to save out the mapping and ability to load in and reset the mapping, and also a way to restore to defaults. Almost there!

Been a long time for updates, I’ve gone onto several other games projects since my last few posts, and while those are fun I’m actually here to talk about something slightly more boring but possibly useful enough to share the code/pdf!

For work I end up taking a lot of notes in notebooks, but one of my peeves about that is I often end up with so many notes that I burn through notebooks fast.
Fast enough that I’ve decided I’m going to just print and bind my own damn notebooks (Some of the ones my wife got me on some sale deal lately are smaller than normal, so I burn through one notebook in about 2-3 weeks, they came as a pack of like 10 or so little notebooks, but it’s kind of bothersome to have to swap notebooks that often because it means I might have to reference something across multiple little notebooks.

Part of having a notebook of course is having lined paper to print onto the copy paper in order to have some lines to write on, if I don’t do that my writing will warp all over the page.

You can find resources for printing lined paper all over the place, but the slight issue I have is that usually they’re meant for printing onto a solid 8.5x11 inch sheet of paper, which isn’t conducive to binding together into a notebook.
What I want is to basically print something sideways onto an 8.5x11 sheet, so that I can just fold it in half, stack a bunch together, and staple them together into a notebook segment like you might see in one of those fancy schmancy traveler’s notebooks.

So to do this, I decided I may as well use LaTeX, it’s a tool I’ve used on and off over the past 10 or so years to make various pdfs of stuff.
I found this resource for how to make lined paper using LaTeX and tikz: https://michaelgoerz.net/notes//printable-paper-with-latex-and-tikz/

It’s a good resource, and it got me 99% of the way there!
What I did was I took his college ruled letter size page: pdf download, tex source
And then copied out the college ruling, and then turned it sideways to landscape, added little date lines at the top left and right sides of the sheet of paper, and then duplicated all that to be on a second page too (because when printing multiple copies, a printer does not want to duplex print the same document onto each side of the page, for whatever reason when test printing it decided to just spawn a new page entirely for each copy of a 1-page document. Yeah I guess that makes sense when you normally print multiple copies of a document, but that means we need to have two identical pages in our pdf in order to print it properly)

So here’s the code:

\documentclass[letterpaper, 10pt,landscape]{article} %for letter size paper
%215.mm x 279.4mm
\usepackage{tikz}

\begin{document}
\pagestyle{empty}

%page 1
\begin{tikzpicture}[remember picture, overlay]

\tikzset{normal lines/.style={gray, very thin}}

%draw date lines

\node at (current page.south west){
    \begin{tikzpicture}[remember picture, overlay]

        %left side date
     \draw[style=normal lines] (0.15in,8.0in)--(0.55in,8.0in);
     \draw[style=normal lines] (0.65in,8.0in)--(1.05in,8.0in);
     \draw[style=normal lines] (1.15in,8.0in)--(1.55in,8.0in);

     %right side date
     \draw[style=normal lines] (9.45in,8.0in)--(9.85in,8.0in);
     \draw[style=normal lines] (9.95in,8.0in)--(10.35in,8.0in);
     \draw[style=normal lines] (10.45in,8.0in)--(10.85in,8.0in);
        \foreach \y in {0.71,1.41,...,19.81}
        \draw[style=normal lines](0,\y)--(11in, \y);
    %\draw[style=normal lines] (1.25in,0)--(1.25in,11in);
    \end{tikzpicture}
};
\end{tikzpicture}

\pagebreak

%page 2
\begin{tikzpicture}[remember picture, overlay]

\tikzset{normal lines/.style={gray, very thin}}

%draw date lines

\node at (current page.south west){
    \begin{tikzpicture}[remember picture, overlay]

        %left side date
     \draw[style=normal lines] (0.15in,8.0in)--(0.55in,8.0in);
     \draw[style=normal lines] (0.65in,8.0in)--(1.05in,8.0in);
     \draw[style=normal lines] (1.15in,8.0in)--(1.55in,8.0in);

     %right side date
     \draw[style=normal lines] (9.45in,8.0in)--(9.85in,8.0in);
     \draw[style=normal lines] (9.95in,8.0in)--(10.35in,8.0in);
     \draw[style=normal lines] (10.45in,8.0in)--(10.85in,8.0in);
        \foreach \y in {0.71,1.41,...,19.81}
        \draw[style=normal lines](0,\y)--(11in, \y);
    %\draw[style=normal lines] (1.25in,0)--(1.25in,11in);
    \end{tikzpicture}
};
\end{tikzpicture}

\end{document}

Run that bit through pdflatex and you get two pages that look like this (can’t upload the pdf because of reasons…)

Print them duplex, flipping on the short side (since this is landscape) and then presto, you got a double sided sheet with lines that you can print a bunch of and then fold and staple to make your own notebooks.

I haven’t run all the numbers here on cost savings but I think it’s safe to say that when you get 1500 sheets of copy paper off amazon for $23 it’s going to be cheaper to make 1500x4 pages of notebook paper (remember we’re talking the 8.5x6.5 sheet from folding the 8.5x11 in half, roughly equivalent perhaps to an A5?) than it is to buy that many pre-made refills of a notebook.
In fact some of the inserts I’ve finding for traveler’s are even narrower than these, running 8.25x4.25, so this may even be bigger sheets of paper!
