Coolcoder360's Devlog/updates thread
A surprise break from engine progress
Wanted to discuss about some other things that came up yesterday that caused what could possibly be considered a disruption from engine progress.
I use Archlinux btw.
And I did an few updates yesterday and all this past week, then rebooted my machine yesterday, and the install broke. Wouldn’t even boot, on either my 5.15 kernel or my 4.16 kernel I keep as a backup. Got stuck on a waiting for save/load /dev/rfkill watchdog type message and had no login prompt or anything. I was able to later boot with the 4.xx kernel (and the 5.15 kernel too) with the
nomodesetkernel option specified in grub. That’s all fine and good, but
nomodesetdisables the Kernel Modesetting, which is basically saying when the GPU driver would set up the screen display size, etc. Well, most drivers, the amdgpu driver I use definitely includeed, do not support the type of modesetting that would be done if you specify this option. So that means my system boots, but I cannot get the GPU driver to work properly.
What this meant for my 5.15 kernel is different from my 4.xx kernel. 5.15 I compiled myself because that’s the only way to get a kernel to boot on my setup (see below) and it also was configured to use only the amdgpu driver for graphics, on boot, it does not show the boot logs you typically see at start when you have those enabled on linux. instead you just see some pixels at the top of the screen flickering and changing, since the display is showing memory used for something else. With
nomodesetit could “boot” and I would get put onto the login prompt, I know this only because I could see a pixel pattern that it settled to with some blinking pixels after about a regular boot time.
I could then even log in, and watch that pixel pattern change!
So instead I booted to the 4.xx kernel, which did show the boot logs, and would spit me out to a login prompt I could see. logging in worked fine, but then if I wanted to run startx, it initially didn’t work with my config because the
amdgpudriver was specified in the config. So I remove the config and ran
startxfce4(I used the XFCE4 environment) and that did actually spit me out onto a GUI desktop once the config was removed. A 800x600 GUI. Because of the nomodeset, that was the best I could do.
So this is a bit of a pain, and I decided its unworkable, so I did some testing yesterday to try to figure out what the issue could be, from checking some systemd and other configurations in
/etcas well as checking the logs of what was updated.
I then decided its not worth trying to fix it, because of why I need to compile custom kernels anyways, that actually limits my ability to do any kind of distro hopping or anything like that.
Why I could’t run a non-custom Linux kernel
I got my desktop workstation as a refurb workstation from pcserverandparts. It came with two 2TB HDDs set up in the BIOS in a RAID 0 configuration. Once I got it I did not change that configuration, I put Windows 10 onto a USB stick and installed it, and then promptly installed games.
Then when trying to install dualboot linux onto it, I discovered something awful. I couldn’t for the life of me get Linux to boot from it for me, for the longest time.
The issue turned out to be that you need to have a very specific kernel setup, that I only once was able to completely build from scratch, using Gentoo’s genkernel tools. This consisted of a special
initramfsas well as a build of the kernel. This special build needed to have the kernel build to include
mdadmnot as a module, but compiled right on in. it also needed some configuration i don’t remember anymore in the initramfs and could never successfully build again on archlinux (it started Gentoo, but I got tired of compiling everything on HDDs so I live swapped it to Arch by pacstrapping myself an arch install in a folder, and then copying files from that into the root of the OS while I was running that same OS. That feels both exhilarating and scary af at the same time, but super bad-ass when you pull it off and it works) So I was stuck with using an old
initramfsfrom the 4.xx kernel, with the newer 5.15 kernel.
This whole mess meant that basically I relied on the setup I had in that install and could not or did not want to change any of it. Until it conveniently broke and I said forget it all.
So I went and solved it. I backed up my stuff from both the windows partition and the linux partition, then I went into the BIOS, undid the RAID configuration. Then wiped it, and now I have installed debian onto it (I had it laying on a USB stick already from installing it onto a laptop) and I’m running the KDE plasma desktop environment.
I also set it up, so I have one of the 2TB drives is my /home, and the other is partitioned into a 30% sized partition for my root partition, and then a EFI and a swap space of course. This way I can create new partitions and then do some distro hopping, while still having access to my /home and files.
I’m a bit sad that my arch install of 3 years broke and I wasn’t able to or didn’t try to fix it properly, but I’m quite glad that it helped me get rid of that hindrance of the drives being in RAID, and it’s about time I got back to my distro hopping roots. I say even though I’m likely to not even switch away, I love Debian as a rock solid distro, and this is my first time running KDE on a machine that can handle it.
Who knows, maybe I’ll get going on some Linux From Scratch stuff and do that instead of Gentoo or Arch or any of that.
Now I just need to re=clone my game engine project and get back to it!
And maybe see if the VR works better or if steam and maybe lutris work better and I can run Epic games?
Back onto the Game engine
Brief follow-up to last time on my desktop: It’s works so smoothly on Debian with KDE plasma, I’ve even been told that my time on Arch was what the stereotypical Linux user has to deal with, where things break or don’t work left, right, and center, but my time on Debian is what Linux is meant to be, stuff kind of just works out of the box (once you install things). With Debian I have steam working, games that didn’t quite run as well on my Arch setup now run perfectly with Debian. I have Epic Games launcher installed via Lutris and working, and most games there (except Cities Skylines, which I think also required extra setup on windows to get some 3rd party launcher) all seem to work out of the box with no issues.
So I got my engine checked out again, installed all the dependencies I forgot about needing to compile it, and now it compiles again, back on track.
Had an issue where my
JsonSerDeswas outputting some garbled stuff at the beginning of the json output, fixed that with a
strdupand then a
freeafter it was used.
Next issue I’m having now I sort of foresaw. Basically Pico Json has limited facilities for how it will store numbers in json. I keep track of assets via what I call a
RUIDwhich is basically a
uint32_tbut picojson just stores things as doubles. I think this might be why I’m having issues, where basically I save out the RUIDs for assets to the save file, but then when loaded back in from the file the RUID is different. So I suspect I need to do a special case with handling ints and unsigned ints to be saved out instead of passing everything through to doubles. Not sure why the library just doesn’t already provide int save/load to json, but it might also be that one would expect a double to always work and have the same value (I kind of did, maybe some sort of precision thing?)
RUIDs and File/asset loading
Wanted to also mention more about the RUIDs, i don’t remember ever really going on about that in depth, but I’ve been gruedorfing for nearly a whole year now (currently writing this part on Feb 1st, will be a year on Feb 9th), so its hard to remember.
Basically when I was designing how I wanted asset loading to work on my engine, I read a few blog posts somewhere (That I likely won’t be able to find again) about it. Basically I want to be able to create a zip, archive or something like that and be able to load things from there, but I still need a way to reference the asset files, even if the path they are in in the final build is not the same as during development.
So I decided on the RUID mechanism I use. Basically I take the string path that is where the file is while doing development, and then hash it to a uint32_t, and store that as the RUID. In my
FSManagerI make a map of all known hashes and their paths just for use during development. This means that during development, I can just give it a path, and it’ll compute a hash from there, and if it’s not loading from an archive, it’ll just use the path.
Then later when I go to make a zip or other form of archive, I can likely make some sort of manifest file/entry table or something basically saying what offset in the archive the asset for each RUID is. So this way I can potentially even just have assets be saved on a server somewhere, and then have my
FSManagerhandle caching them, and loading them from server and the rest of the game engine just act likes normal, give it a RUID hash, it works find and uses the lookup table. Give it the path that was used for the asset during development? just compute the hash from there and do the lookup with the generated hash.
This method is also nice because then when I’m writing a Lua script, I can reference assets directly with the path instead of needing to use some silly RUID reference or needing to write/have a tool to let me select the asset and use the reference. It’s fine for a script or something to ship in the final game using the asset path instead of RUID.
I feel like I keep going on about all sorts of things I’d rather work on than debugging the save/load stuff, and it’s true, I’d much rather be shoving a UI system into this thing or implementing audio whatevers, but I also need the save/load to work, otherwise there’s not much point in having an editor UI, because that would just let me implement a bunch of stuff that can’t be saved. Plus I’m sure the UI and audio implementations will all have their own difficulties and their own problems to debug. That seems to be the neverending task of development.
One thing I think I will likely do later, is try to sort the issue tracking stuff I have better, to let me have the milestones be in smaller chunks, that could happen more quickly. Part of my difficulty with that though of course is that I like to sometimes take a break from the pain of the hard stuff, to go work on something fun, so some of the things I’m working on now weren’t originally in my first milestone. So I think part of it will be planning some fun things to do in each milestone, along with some of the less fun things, but of course there’s also the issue of things that were fun later becoming less fun when they have problems.
Also I think I’ll try to plan some time to go run cppcheck or other such tools on my engine, to try to make sure it has a solid base to build the future things onto. Otherwise I may find myself scratching my head on why things don’t work, and hopefully I won’t end up with stability issues for too long, I suspect some of the stability issues I’ve had in the past could be resolved with some serious valgrind work or some cppcheck stuff. it’s difficult to make things like this be completely bulletproof, but I’m sure if I keep running the tools and fixing parts here and there that it won’t be too large of a task to do a little bit each milestone
1 Year anniversary of Gruedorfing!
Huzzah, that’s right. I started this stuff on Feb 9th 2021, and now here we are at Feb 9th 2022 (not at time of writing, this might be posted early, I’m writing this on Feb 3rd because I already have things to mention that seem to go well with the 1 year anniversary thing)
Have I gotten a lot done? Well not as much as I would have planned/hoped when I started, I sort of hoped to have completed a few of my planned milestones last year. But I do have good news, I completed 0.0.1! sort of.
0.0.1 milestone complete!
Again, sort of. I didn’t bother finishing testing the scene save/load, I just fixed the errors I was having with my test case of testing material save/load which was to have a lua script manually save/load materials etc, I didn’t let the scene save it all and load it all, I likely have to add material saving still to my scene save/load.
But now I can go on to my next milestone of doing UI things! But I should also probably try to better define what the milestone will look like, the first milestone of 0.0.1 took me so long to wrap up I think I should definitely downscale my expectations for 0.0.2, just because I’ll likely also try to scope creep the next milestone too.
But before we go on to rant about 0.0.2 planning, let’s cover what we have implemented, and what is tested, so far:
- Lua script running, ticking
- Lua APIs to load/save meshes, materials, load textures, add/remove entities and components to entities, bind/map lua functions to input actions
- working input manager that is mostly tested (but with mouse input being broken due to using the wrong type of mouse input)
- PBR Deferred renderer with a forward pass that handles rendering text and will eventually handle rendering transparent/non-opaque objects (transparency/blending not yet implemented or tested)
- Only does direct lighting so far, no IBL, no GI
- 3d point lights do work, no other light types
- In engine versioning that should work with Jenkins
- (Tested, but I don’t trust Jenkins to not entirely break, need to also back up Jenkins configurations etc.)
- docker container which can build engine, working in Jenkins
- Scene loading/saving
- Generic Json serialization/deserialization implementation, can be drop in replaced with other types of serialization
- Material creation, save/load
- mesh save/load, creation from Lua
- Model loading (from files with Assimp) ported but not tested
- EnTT based Entity-Component system
- Hierarchy support added
- Multithreaded Render and Update loops
- Generic FSManager abstracting away all filesystem operations from the rest of the engine
- UTF-8 support for rendering text in Unicode for various languages
- and font loader for loading/rendering fonts
- Text input with my own font loading/input methods.
- used for a lua only console with commands
Wow that is a lot, definitely makes me feel better about how long it took to do all that. I have hopes that now that most of the framework is put together, like the rendering, EnTT, lua scripting, etc, that future features will hopefully be at least a little bit faster to implement, or at least I’ll have less time spent debugging the basic framework and more on the actual feature implementations themselves.
What’s in store for 0.0.2
So initially I had planned for audio to be in 0.0.2, but I think that’s a lot to do Audio, since I also want UI, etc etc. Basically this is the classic case of the product managers wanting everything done yesterday for free, but I’m both the product manager and the dev in this case, so the only person who loses here is me.
So I think here’s my initial plan for 0.0.2:
- UI support with Nuklear
- I think this is important because it means I can make the editor more usable than remembering console commands, combine that with having the scene save/load working at least a bit better, then it should mean I can make, save, and load back scenes in engine, which would be helpful for testing rendering in the future, both efficiency/benchmarking, as well as other tests.
- Add Lua API to load models from files into meshes and materials.
- This way it’s useful for the editor to be able to import more complex meshes instead of either having to manually define the vertices, faces, texcoords, etc.
- Fix Mouselook issue
- add keyboard movement to move around scenes in editor
Basically 0.0.2 will be the “Editor milestone” to get editing things to be a bit more useful, and easy. Get the UI stuff in, make editor UI, make editing more usable than having to accurately type a bunch of commands.
What else is next for the Engine milestones?
Well, based on how long 0.0.1 took and how much stuff was planned for it in my quire project for it, I think it makes sense to try to keep milestones to be smaller, with maybe 2-3 big tasks, and then 1-2 bug fixes/small tasks. This way milestones continue to be a small bite I can feasibly chew in a few months instead of a whole year.
With this logic in mind, I’m trying to basically have a theme for each of the next several milestones, since there are a lot of major chunks I still want to put in before I drop the 0.1.0 release, which I would call the “Barely works but has all the pieces together to make a game in” release.
So the next few releases/milestones are likely to be themed like this:
- 0.0.2 The Editor Milestone
- add everything necessary to make editing easier
- 0.0.3 The Physics Milestone
- add support for creating rigidbodies, kinematic bodies, and physics constraints between the bodies
- 0.0.4 The Audio Milestone
- add in the miniaudio stuff, need to figure out if I want to do low level API or high level Engine API, I might just do low level so I can handle controlling the audio data/assets my own way instead of using whatever their way is, but that means I would need to implement some things myself that they likely pre-can into it.
- 0.0.5 The Asset Packaging/exporting MileStone
- This is basically the zipping all the scripts, configs, assets needed for a game into a .pak/archive file to be loaded later.
Each milestone may have some extra nice to have features or bug fixes sprinkled in, but this means there are 1-2 big tasks for each milestone, and then some (hopefully) smaller tasks sprinkled in.
Those milestones also will get me most of the way through to 0.1.0 with the basics of what is needed in a game:
So then making a game by that point would basically be to go into the editor and add entities for things/worlds, write and hook up lua scripts for crap, and then likely writing an init/setup lua script and then hooking it all together.
Only thing missing there is animation, but in all honestly, if I want to make my racing game idea, I don’t think I really need any animation to have physics cars flying around a track, you just need physics to knock shit around, and maybe you can cheat animations by having obtuse ticking/whatever in lua scripts to update stuff each tick. that would definitely get laggy af most likely but we’ll see. If I can chunk out a piece of sh-, I mean, A golden masterpiece game after my 0.0.5 milestone, I think that’ll help me verify that my engine works. skeletal animation and basic animation can all come later/after the fact. Heck controller support can be after the fact as far as I’m concerned, I’m not expecting this thing to be a masterpiece.
So that’s probably about as granular as I want to get with planning for now, There are some other things like translation support and such that I may want to add/move around but this is the basics of what I would need ot make a basic game, and as long as I don’t need anything animated, I could make a shooter, a marble roller/monkeyball game, or a racing game, or any number of other things. Maybe even a golf game, not that a golf game is the kind of game I necessarily think would be the most exciting to make, but it could also have some interesting value add done to it to add loops, and other things. and Golf It is somewhat a relaxing game, so it may make sense to try making a golf game, and it would likely be easier to make into a multiplayer game because people hardly would care about rubber banding in a golf game compared to a high stakes racing or FPS game.
Okay, now that I’ve laid out what the plan is, time to get into the specifics of the UI. Plan is to basically use Nuklear to do my UI, but nuklear works sort of like imgui, where you basically have to call nuklear functions every single frame for every single UI piece you want to render, that’s great and all but doesn’t really go well with Lua scripting, because I don’t want to have to call into a Lua Script just to get the UI stuff going, it seems like it would make more sense to have a data structure or something that is assembled in Lua, and then Lua only gets called when some input happens.
This is great but I realized that its a bit more complicated than I thought, for a few reasons.
- There’s more to a UI than just “Here’s an ordered list of all the widgets I want” because there’s layout involved. each row in Nuklear can have a different height, different number of columns, etc. and they all go into a window. and in the window you can have panels? and then you can have like, trees where there are children UI stuffs that can be hidden/expanded to see, but the same trees can also be used to display trees apparently? I think?
- It’s not easy to convey this all in something simple, I was hoping for just a window class to represent the UI window and then like, json or something for the rest, but it seems I’ll need some more classes to figure it all out since there are rows, with row height and number of columns, and crap like that.
- You have to call the nuklear commands for each widget to fill the context with what is there, and then you have to parse out some other nuklear commands for what to draw, or you can somehow get what you need to draw in a different format? trying to still figure out how I can render this crap out without tying it to being openGL only since I know my renderer is wayy to involved/connected to everything else right now and I don’t want to make that problem worse for when I want to add GLES 3 or Vulkan. (Yes I want to add at least one of those if not both, GLES 3 would get me mobile and web I believe, Vulkan would also get me mobile support and supposedly if you’re good it can be more efficient, but I believe that to rely on the skill of your implementation and not just from just throwing crap from GL to Vulkan, so I doubt I’d actually have Vulkan be faster)
So I’m not entirely sure yet how I want to do it, I likely will want to get the rendering working with just the windows, and then later I’ll go add in support for the widgets and such.
Likely I’ll end up having some sort of row/bucket type class/struct, and then have that contain various widgets that would be in that row, along with data for the row height, columns, etc.
I’ll also need to figure out how to configure the style/skinning as well, but I think that’s a later feature. I think once I get started I’ll be able to break it into smaller chunks, create more stories in quire for pieces, and maybe rearrange some effort to later milestones, etc.
Had some troubles with porting the Nuklear examples, I haven’t gotten Lua bindings or anything together for this just yet, I basically just ripped the example nuklear rendering code for opengl out of an example, and shoved it into my own little wrapper class, and now I have a window like this:
I consider this some pretty good progress!
Okay the title bar is missing from that one, try this one:
This is great! Basically proves that my UI rendering works, along with the rest of the nuklear pipeline (it’s kind of a lot of setup stuff, very confusing, especially if you want to tweak the UI colors, use images, skin it, etc). I haven’t tested any inputs yet or that my code to shove input through to Nuklear works, but this is a great start.
Next I need to figure out how to store rows/UI widgets in my windows, and then also come up with some sort of Lua API to specify what the inputs should be, as well as get the values/inputs out. that’s likely going to be a bit rough I think, but I’ll see what I can do. After I have basic widgets working and lua bindings together I can then work on fleshing out more of the widgets and then also putting together a better editor UI, then I can really get going on stuff.
some art stuff/side project
I decided I wanted to test out Godot 4.0 Alpha 2 for a little bit to see what was new. So I also spend some time in blender making a few things.
I will say that I don’t think I’m ready to work in Godot 4.0 yet, there were some issues I had importing models to where I’d drag in/add the model to a scene, but the mesh would not show up all of the time. That difficulty made it difficult for me to continue doing just because it was not reliable and I think I found a workaround, but the workaround was too much work for it to be worth it for me to continue.
I did however do some stuff in blender and made this candle model with fully procedural textures (that I plan to bake out and export for my engine, my engine can’t do procedural textures and I think that’s not in scope. for now.)
Not much progress on the engine from last week sadly, partially from being distracted with the Godot 4.0 Alpha 2 build testing I was doing. Some small amount of progress on the lua bindings for the UI stuff though.
Lots of other things going on, trying to buy a house, and it has a bundle of things wrong with it that we need or want to fix/repair before or shortly after moving in.
Water heater isn’t to code and is unable to be replaced without cutting whole in the drywall, failed radon test, dishwasher doesn’t work, garbage disposal doesn’t work, whole house fan vents don’t open properly, tree needs branches removed, yadda yadda yada.
But hey! it’s a house and it has lots of storage. like fit our 3 crock pots and the instapot under the counter and have room for like 6+ months worth of pantry items for us kinds of storage space.
I’ve also realized just how expensive furniture can be… we have a big enough space, and I’ve always wanted to have a bar in the house we would get. Issue is, bar counters and bar cabinets all run well into the $3k range each for the nice ones with reasonable size, and we’re going to want one that locks because I have a 13 (almost 14) yo brother-in-law who we like to have visit, and we don’t need him experimenting with that stuff without our supervision. I told my wife we’d have to get just the best farthest bottom shelf cheapest tequila for him to try if he ever asks about trying alcohol, can’t let him go come across the good stuff while we’re not there otherwise he might end up liking it.
So because of all that expense, cost, and that we want something that locks, I’m considering making a bar cabinet (and probably bar too) myself. I did a little bit of wood working growing up, mostly with my dad since he was the one super into it. I’m not sure I’d be into it enough to get like a tablesaw or anything fancy, but if I could do it with a few hand tools maybe, then I could probably slowly come up with a bar cabinet.
I’ll probably start with looking around for plans or coming up with plans for the bar cabinet in freecad. Maybe I can 3d print some of the hardware myself and then assemble the rest of it out of plywood or MDF. Be on the lookout for some CAD stuff in the future I guess instead of just game dev.
Not much to speak of this time, still slogging through the lua bindings for the UI stuff. I now have it so I can do all the same things before you saw for showing a window, but in lua scripts now.
Still no widgets or anything like that but at least now I have somewhat parity between the C++ and the Lua bindings.
Next I think is implementing lua bindings to do the Rows, which are basically to hold each row of ui elements in the window, and then I’ll need to add the C++ and lua to handle any actual input widgets or labels or progress bars and other such things.
Don’t remember if I’ve explain it before so I’ll explain it again, basically the way Nuklear seems to work, based on my possibly limited understanding, is you essentially have a “window” which is essentially a bucket that is a separate window in the UI, you can configure it to be closable, movable, minimizable, resizable, etc.
Then in that Window you have the widgets, but they’re laid out or organized in rows. how exactly they are laid in rows can be changed based on how you want to layout the gui, but basically what I’m planning to do is to have a Window object that just holds Rows, then have the Rows actually hold the UI components themselves. that way I can programmatically generate the full window and specify layout in lua, and all that happens is my UI Manager calls draw on the window, the window calls the nuklear methods to set up the window, then calls draw on its rows, and then each row does the call to set up the layout, and then calls draw on its widgets, which then just does the nuklear calls to set up the actual widgets (and will then get the input results from Nuklear and then ping back into the configured lua script/method with the input from the widget)
I was reading a factorio blog post recently and they mentioned doing automated end to end testing, so I thought it would be good to think about how that could be done, perhaps there are some other frameworks or something that could be used.
I do think that basically having a way to provide fake input to the engine would be easy enough by just adding some stuff to the input manager, to allow triggering input actions outside of needing glfw to actually register the events. I haven’t fully fleshed out the details of what kind of scripts the tests would be written as, but I think it would be helpful to start at least figuring out what engine modifications might be helpful to doing automated tests.
Things like being able to run in a headless mode, that way you can avoid needing to use GPU and still be able to run multiple tests in parallel on the machine.
Maybe having some sort of “on demand” rendering to allow taking screenshots when needed but otherwise just don’t render anything? I’m trying to figure out how useful automated tests would be for testing actual gameplay vs testing just general engine features to ensure there are no regressions, and I suspect taking screenshots may not be the most useful, because I could imagine that the graphic quality would vary a lot at least while a game is being worked on, but maybe if there was a consistent test case for the engine to verify that the graphics rendering seemed to match at least somewhat closely between different renderers?
Additionally, It might be worth being able to capture state/save the entity/component state to compare, then comparisons of state could be done possibly between specific entities that are having functionality tested on, and it would work regardless of the graphics changing.
So those are some thoughts I had about potential features that might need to be added to facilitate writing automated tests, so hopefully then during development of a game, I could set up some automated tests for that game to test some functionality, maybe to verify that the main menu, pause menu, options menu all work and don’t crash, and then I could maybe add them to all run in Jenkins to be automated like once a week or month.
Moving next week to a new place. lots of stuff going on for that, and not so much game engine progress expected. But once we get the place set up I’ll probably be right back at it trying to get my UI stuff figured out so I can get the editor on track. Once the editor is on track I’m hopeful I could start making some real games perhaps, even without fully workable physics or audio.
Took a bit longer to complete the move and get my desktop set up than expected, but had an unexpected funeral and road closure keeping me in a different state, so the one week I expected to not have any progress turned into 3 weeks.
Still trying to set up my office, need to set up the 3d printer and better route the ethernet cable from the kitchen on the first floor to my office in the basement. I got a 500ft spool of bulk ethernet cable to be able to route that around everything along the walls, and was going to 3d print brackets to hold it in place.
In order to better route the ethernet cable I’m designing some brackets to use to mount it to the wall so I can 3d print them off, figure since I’ve got a house now I may as well make use of the 3d printer to make things.
The bracket is basically just a half circle with a little hole for a nail to go through:
but I made it parametric in FreeCAD so I can change the size of the hole to fit different nails or screws, and the size of the arc to fit different size cables, or the thickness or overlap of the parts to make it more sturdy if needed. Learning FreeCAD has been good, and I think it might help if I wanted to make furniture or other things that may not be 3d printed, but require good design/planning ahead to make sure everything fits together. Blender is nice for 3d but not sure it’s really parametric in the ways I need to make physical objects.
The status on the game engine is pretty same-y same-y, still doing UI Lua bindings and stuff to try to get it to where I can at least add a single widget to a row and add that to a window.
Once I’m that far implementing other widgets shouldn’t be too bad since Nuklear pretty much pre-cans all the hard parts, so I’m hoping it should be smoother at that point, then once I’ve got a few widgets in I should be able to get some sort of editor UI going and then hopefully from there it’s a simple verifying the model loading stuff was ported properly, maybe dress it up a bit to make it easier to fit into the current framework of how meshes work, and then I should be set for the basics of things.
Then I’ll tackle animation, physics, audio, etc in some future milestone, but I could feasibly start making levels/logic/something once the UI/model loading stuff is in. UI styling might need to be done at some point to make it not look awful, but that’s a longer distance worry for now I think.
Been in a little bit of a rut with the engine where I just have a slog of things left to write, make bindings for, etc for the UI stuff.
So I haven’t been super excited to work on the engine between that and all the other crap going on, so I figured it may make sense to start a side project to do something to still do coding/crap but make it so I can come back to the engine with a fresh mind, like how I worked on that dungeon crawler ages ago for a few months.
Effectively nothing has been finished since last time other than making a Label class and lua bindings for it, and filling out the implementation using nuklear, but not testing it. Now I’m trying to do a button but not really excited about it.
New Side Project
So the new side project I decided to do literally 1 minute prior to writing this, basically I was just on my computer clicking around the browser windows as one does when supposed to be doing real work instead, and saw a GOG window that I had left open on the main store page, with a sliver of a screenshot of a game called Hero’s Hour on it. (not sure why that link looks like xn–<name>-nw6e to me but maybe that’s a preview only bug?
Opened it up and I saw the graphics and I thought to myself “making a little top down world map view RPG might be neat, maybe jrpg, maybe not, not sure. let’s open Godot” and so a game idea was born. that is currently only maybe 5 minutes old and will probably die about 5 hours from now.
Anyway figured I’d stop losing for that update, will try to write again next week on how long that new game idea survived.
Side project progress
Going to jump right to the side project, nothing to report for the engine
I’ve got a tileset I’ve been working on, forgot how fun it is to make a pixel art tileset:
The tileset has grass, dirt, sand, dirt/sand path, and paved path, trees, various buildings, and some mountains. It’s meant to have some tiles be on a layer over the top of the base ground layer, which may make the mapping a little bit complicated, but shouldn’t be too horrid.
I think I’m going for more of a jrpg type thing, or maybe sort of like a roguelike, I’m definitely leaning towards using some proc gen (discussed below) for creating maps/overworld, etc, and I’m thinking turn based will be best.
I’m also not aiming to have different heights/levels in the map, that’s just too complicated art wise and mapping wise, but I’m sure it can be faked with setting up tiles in a certain way.
So I’m planning on using proc gen to generate the map, instead of manually placing tiles, that’s nice because then I can use it to create:
- Replayability, you can play the same game multiple times with different layout, different world, and different experiences
- Larger worlds than I care to make manually, which is great because making large world maps, or lots of small interiors sounds like it could get very tedious, so this way I can make a larger world with more crap to do, without spending too much time on all the individual crap, I just make a tool that makes each type of crap and then another tool to tell the crap where to be crapped out at.
I plan to do at least some of this proc gen, for the world map at least, using Wave Function Collapse. You can see one sample implementation and what it does here but I’m planning to make my own implementation in GDScript (for now, maybe I’ll figure out GDNative later if that’s too slow) so that I can understand it, and potentially tweak it if needed.
The gist of wave function collapse (WFC) as was described in one of the several videos I watched on it, is that basically it’s like solving a Sudoku puzzle, you start with a few pre-chosen tiles, either randomly chosen or given to you, and then you go through all the other slots and you can narrow down the options remaining of what value/tile can go there, until either you get to only one possible tile, or as few as can be, then you just randomly choose on from the options that can be there at that tile, and then you update the rest of the slots with the options remaining.
The way you know what tiles can go next to each other is by defining the possible adjacent tiles to each tile, which if you look at the above github repo, can be done by providing a sample or “training” tilemap/texture, which let’s the algorithm know how/where to put different tiles in relation to each other.
One thing to note about WFC is that it is all based on local connectivity, how each individual tile connects to its neighbors, there is not really any stored/saved data about bigger picture things, which means you can very easily end up trying to make a generator to give you square rooms, but wind up getting non-square rooms, or other similar issues, simply because the WFC algorithm doesn’t really have any data on the inside vs outside of the room. This kind of difficulty can be solved though, by including a sample tilemap that uses a different tile for the interiors of each room, compared to the exteriors, that will keep the room interiors internal to the room and prevent the room from sprawling on.
How is WFC different from Wang Tiles?
Wang tiles are something I’ve done in the past and I think mentioned somewhere upwards on this chain, and I wanted to kind of mention how they seem similar at least in theory to WFC. WFC you define the possible adjacent tiles and try to pick a tile that can go in a spot that is adjacent to the others, based on edge connectivity.
In theory, you could probably combine WFC with Wang tiles and be totally fine, so what’s the difference between what I’m trying to do now and what I did before?
Previously, I did Wang tiles, which the ones I used were basically large blocks that were made up of many smaller tiles/pieces, in this case I’m trying to do WFC on those smaller pieces instead of having to make the tiles, and then manually create rooms/chunks with those tiles, I can just focus on making the little tiles, then piece them all together in an example map, and then let WFC do its thing from there.
Another difference between what I did earlier and what I"m doing now, is that previously I did not propagate any possible options through the map when generating a map, instead I defined the edges of my confined/finite map as being closed off, then randomly chose tiles to fit with that, and make sure that the connectivity of any other already placed tiles fit in with the connectivity of the tile chosen. Is there a reason you need to keep track of and propagate the possible tiles instead of just picking from pre-computed connectivity lists where you group all tiles with specific connectivities together? Not as far as I can tell, in fact I think having to propagate your options through would be slower computation wise, however, this lets you go through and find the tile with the lowest number of possible choices, and fill that in and propagate from there, so hopefully (and this is hopefully, I suspect it’s still possible) there will be fewer instances of the algorithm running itself into a corner where no tile exists that can fill a spot, which happened multiple times when doing Wang tiles, but meant in order to get more generation to work, I had to spend a ton of time manually creating new wang tiles to fill the connectivity combinations that I didn’t create yet, or deal with having a 4 way intersection wedged in there to not block off any paths.
I will say that doing the wang tiles I did before did mean I could just do random walk to make sure you could get from point A to point B by pre-defining the necessary connectivity without defining tiles for those slots yet, which let me create a traversable level from start to finish, but here for an overworld I think it should be possible to not run into too many cases where something would be untraversable, or if anything I can pre-define some parts of the overworld to make sure that things are traversable, but then just proc gen the rest.
Also in theory, with WFC I could make an infinitely generated overworld, and then generate each individual place on the fly. Which, that would be great and all but if I want like a classic story, and maybe some sort of sane leveling system, it may make sense to limit things a little bit to prevent things from getting too insane, although I’m not going to rule out quest and story proc gen just yet, but I think for a better experience for a jrpg type game, some intentional design is important instead of just letting proc gen go completely rampant.
Side quests though, that’s probably where I’ll let proc gen go because if the system generates towns/buildings/whatever, then the system can fill those with stuff, I’m not going to hand make everything that is like that. Proc gen for weapons, tools, items etc will probably also be useful.
Next steps on this project, I think getting the WFC actually working. I’ve rambled on about this, but so far I have a file in Godot that doesn’t do much, it stores out the adjacent tiles from a pre-canned 2d array so it knows how to connect things, but it hasn’t figured out how to use that to create anything just yet, and the propagation of options/narrowing down the options is going to be a little bit intense.
So far I’ve been enjoying making the tileset so that’s good, may make some sort of at least placeholder character for now, or maybe go through and make some items or ui features for later.
After the WFC generates the array of possibilities I think it’ll be a matter of getting it to create the TileMap and then putting that for someone to see, then making it so you can walk around in there, have collision, etc.
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.
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.
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.
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.
I think next steps are going to be
- Add text input boxes
- Add checkboxes
- add radio buttons
- try to fix up the reliability a little bit to make it more reliable
That’s all for now!
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:
- My notes aren’t easy to search or sort
- my handwriting is horrendous, so being able to read my own writing is sometimes difficult, or nigh impossible
- 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)
- 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
- 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.
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:
- “rows” which are basically a way to have a row of inputs in a window
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
- 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.
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
- 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.
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.
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
FutureClass 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(), 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
std::shared_ptr<Future<Texture>>are cleared up now and the
getResourcefunctions 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
workqueuestuff, 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…
