Anyone have any old freeware devs' sites from before 2010? Particularly those that hosted their freeware games
I'd like to look at their sites and games for inspiration (since I might end up just being a freeware or FOSS gamedev)

I'm writing something to convert audio assets from FLAC to Opus for my game engine.

>>105797871
Isn't that like a 2 line shell script?

>>105798095
its ffmpeg

>>105798095
Only if I used some external program.

>>105798200
FFmpeg is not a part of my engine.

>>105798244
Ah yes, the excitement of spending days, or even weeks for something you have to do maybe a couple of times and can be easily achieved by a 2 line shell script.

>>105798266
I enjoy programming.

Sogeki no shima desu ~~

>>105798338
I mean sure, but engine is a big enough project that you shouldn't need to make detours like this to find something to do.

I've made a physics engine, a rendering engine, but writing file format converters is peak stupid

>>105798634
The way I see it using FFmpeg would be making a detour to avoid implementing support on the engine for the media formats that are essential to its functioning. It could make sense if I was under some urgent time constraint to get the audio system working but that is not the case.

That's all. Also - 105k LoC.

>>105801821
i would not let any project I write get past 20k loc
and 20k still feels obscene

>>105801898
20k isn't all that impressive. I push something like that at work every month if there is major implementation going on.
Granted - these days I mostly replace 100k of old code with 25k of new code, but still.

>>105801898
While I do agree with the sentiment that less line of code is generally better, 20k is not "a lot" for that kind of thing, and arbitrary limits don't really help.

using*

does it make any sense writing a game in C ? seems that games are one of those use cases where it makes sense to use OOP 100% of the time

I need actual serious advice.

I am making a 3d mmorpg in c++, Should I care about optimization before the bottlenecks start to appear, or should I only care about it when they show up?

obvious optimizations like broad and specific collision and heightmap interpolation are already at play.

>>105797658 (OP)
nice balls anon

>>105804537
honest question how do you know where the bottlenecks are if they haven't appeared yet?

>>105804629
Looking at the complexity of the problems, collision is likely the biggest cpu user and the heightmaps are the memory one.
Considering the experiences I am having now it's clear that looking at the problem before taclking it gave good results, but at the same time I fear I might be losing too much time with ECS, FP + OOP problematics and coding less.
I think in the end of the day I just need to optimize where I know I will have gains, then just rework what gets problematic.
Something obvious I am doing is making sure the systems can run in parallel in the future (damage and collision being calculated by a sole core)

>>105804192
lol maybe in commodore days grandpa

>>105804708
As an example, right now I am thinking that reactive collision instead of predictive collision could save a lot of memory

>>105804828
so you already wrote one algorithm that you don't need and you want to replace it with another algorithm because surely this time it will be worth it. do you see what they mean by root of all evil?

>>105804887
I guess at least I learned a lesson.

Anyone else feel like naming their vulkan wrapper/engine after a star trek character?
that or a volcano

>>105802964
What are you looking for in particular?

>>105804537
bottlenecks are the last thing for you to worry about because a real MMO is all about scale.
but obviously you should expect that your first game (that you actually put years of effort into) is going flop with a few downloads, unless you have a really easy way of getting exposure (like embedding yourself into a existing community, such as just copying the community / game and leaching from them). Generally at your second game you either give up or actually get the exposure you need for the next game because it turns out that most games look a lot more fun and interesting when it's not released.
Anyways, ignoring that, the big problem is that all mmo's are free and hosting on the cheapest piece of shit that can survive with like 100~ users concurrently (depending on your game, assuming not an FPS, simple movements) is like $4~ a month. That's not bad but we are talking about like 2 cores + 1gb ram (cores and ram can be upgraded), and optional very, very, very slow storage that is $5 a month for each 1tb (1tb minimum) and I don't know how much a speedy database would cost, I was assuming you would just be OK with the data loss from a crash since it's going to be cheaper and 100x faster & the reliable way of doing in game purchasing would be with steam's inventory SDK.
Also if you were doing an FPS, the cost of the server isn't the only issue, it's the cost of the bandwidth, 1gb upload costs like $0.001 or something, and 1 user could download 100mb in like 1hr in a FPS, so 100 users playing 2hr every day would cost 50 cents in one month, CHEAP, but when you scale the numbers and remembering that 90% of the money comes from whales, it's rough.
Also to scale you need an API that can scale the server instances, you can't use C++ on Oracle (which has a generous free tier which doesn't work when you need it + some free bandwidth + auto balancer + linux), but you can use C++ with AWS I think.
The only true DDOS protection is cloudflare which is web only.

>>105805799
actually 1tb of storage costs 10x more.
and 1gb of egress is actually 100x more as well.
But it depends, I haven't actually looked it up and if you hosted it yourself, I believe you hard lock yourself to like 200 maximum, and chinese VPS or whatever you call it services are cheaper but I don't know if you can scale up and spin up new instances using an API.
Also there was the European service I forgot the name of that's cheaper than everything else but nobody can get access to it or something because it's business only.

>I'm gonna make a mmorpg!
no, you aren't

People who have never made a game speculating about making an MMORPG takes me back to the 2000s

Yeah, I'm basically 99% done with my game engine.

>>105806134
Wow, just realized that either the Windows screen clipping tool or Chrome or something else really fucks with the blues.

>>105806134
Which api?

>>105806167
D3D12. Honestly pretty simple so far considering how people hype it up as some impenetrable API. I'm sure doing insane 3D effects and optimizations gets complicated, but I don't think cranking out a 2D game with this would be that bad.

>>105806180
Nigger use Vulkan

>>105806180
well, getting a triangle to render isnt hard, the hard part comes when juggling resources, descriptors, synchronizing multiple queues, and async resource creation

>>105806206
Nah.

>>105806215
Most of that stuff is verbosity a rather than difficulty. Like knowing when and how to add a sync barrier is straightforward. The genuinely hard stuff is memory management which is mostly handled by VMA if you’re using Vulkan, dx12 has an alternative but I don’t know how popular it is. The problem is modern graphics API’s are already outdated. They were made in 2016(9 years ago) and built to be backwards compatible with hardware tracing back to like 2012. GPU hardware is completely different today, more unified and simplified than ever. Synchronization is different. Descriptors are a thing of the past, all GPU’s deal with pointers now. Layout transitions are also no longer necessary. Ironically dx12 is the longest surviving DirectX version, Vulkan is the same age and also committee driven. They definitely need new whole versions asap but companies being retards probably won’t come around until 2030. Metal is the ideal modern api but alas it’s Apple only.

>>105806327
doesn't matter in 2 years we'll just have real time generative ai and 3d programming will be dead

>>105804537
Fix problems you have, not problems you _might_ have. There is a finite set of problems _right now_ and an infinite set of problems that might arise.

As such, a heuristic is to always assume that X will not be a problem until it becomes one.

t. 20 years of experience haver.

gpus should just be tiny game consoles you put inside your computer and the rest of the computer just acts as a hardware abstraction layer

>>105806327
hardware might have changed, but if the apis are old, we cant really do anything about that
>GPU’s deal with pointers now
at least we've gotten bindless resources a while back, despite how little material covers how to transition from bindful to bindless
>Layout transitions are also no longer necessary
you mean in hardware right? apis still need to transition afaik. at least my debug layers scream at me that i cant present a render target
>They definitely need new whole versions asap
agreed, i do hate how the apis have moved to "just keep downloading our latest vendor extensions / agile sdks" instead of just making a good new full release. dx 13 and vulkan 2 cant come fast enough, but i dont think we will ever see them do that

if something seems complex just think about it in the stupidest way possible and then you'll understand it

>>105806327
>They were made in 2016
The 1080 was released in 2016 and is still in common use. Even if DX13 dropped today it'd be 10 years before you could just assume everyone was running hardware to support it, in the meantime you'd be forced to write DX12 and DX13 implementations for everything.

>>105806462
>you mean in hardware right? apis still need to transition afaik. at least my debug layers scream at me that i cant present a render target
UNDEFINED and PRESENT are still necessary but everything else is getting phased out in favor of general. https://www.khronos.org/blog/so-long-image-layouts-simplifying-vulkan-synchronisation

how's raylib for enginedev? everything in one package without having to piecemeal a bunch of libraries sounds convenient

>>105807147
raylib is just a kinda buggy wrapper over SDL
if you're planning to 3D dev it's not a good idea
something like raylib for common lisp would be good though

>>105806632
if im not mistaken those are the "enhanced" barriers in dx 12 right? they at least sound sorta familiar

I don't care, I will keep using DX9 and OpenGL 3.3

Vulkan extensions I'm looking at to make writing a renderer as simple as possible:
Dynamic rendering (+ local read)
Synchronization 2
Shader objects
Push descriptors
Descriptor indexing
Buffer device addresses
Dynamic vertex input state
All of the maintenance and extended dynamic state stuff

Is this a good list? Am I missing anything big?

>>105809621
>Vulkan extensions I'm looking at to make writing a renderer as simple as possible:
OpenGL

>>105809657
Not being able to do something as simple as selecting the graphics device you want to use makes OpenGL kind of unattractive to me.

>>105809762
that is some supreme bikeshedding

>>105804444
I'm working on a game in UE5 (don't tell /gedg/) and OOP makes me want to ACK.

Depends on what you're doing. For stuff like a standard FPS it's ok, anything else and it's a pain in the fucking ass.

I want to make a MUD engine for erotic roleplaying. I want the game to have it's own client so players can add and share artwork of their characters. I want it to play kind of like a multiplayer VN with some form of matchmaking I guess. My question is would it be better to make it a desktop client, a mobile client, or a web client? I have experience in system and network programming only so whichever I go with will be new to me. I find learning frameworks to be more work than simple libraries so I would like to avoid bulky frameworks if possible. It seems like the VN crowd prefers desktop so I'm leaning toward that but I was hoping to find a solution that would be easy to port to mobile at a later date if one exists. I hope to play in bed or the bath without electrocuting myself with a laptop. Thanks, /gedg/!

>>105809762
>selecting the graphics device
There's only one in 99.99% of cases. The user sets their OS to use the GPU they want to use and the OS passes it on to OpenGL. The idea that any players are choosing from a wide selection of devices like a mafia don choosing cigars is just silly.

>>105809993
Can you describe game idea for this engine? How the potential game could look like? Its like MMORPG where you can talk to other players with VN ui or what?

>>105801821
Looks nice. What is the game about?

>>105797658 (OP)
What is the required topics you must learn before learning OpenGL , I know basic C++ , College maths and physics

>>105810285
I don't know if you ever played old MUDs over telnet but that's all I want to make for the most part. I just want a client that displays things more similar to a VN than a chat room.

>>105810484
trig and linear algebra will help but honestly you can just look up what you need to do and copy paste from a tutorial or something.

>>105810562
Fuck just now i realized what do you mean by MUD. nevermind

>>105810461
OTTD and classic Transport Tycoon inspired railroad game with crippling autism level of mechanical detail. Think "Dwarf Fortress" but about running a railroad.

Creator of Diablo made his solo game It Lurks Below https://store.steampowered.com/app/697550/It_Lurks_Below/ using a custom engine in C/C++ written from scratch, no frameworks used. Brevik said he wrote 90%+ of the game in C and the tiny bit left in C++ because of some shortcuts in it.

Brevik's own words the code consists of "tens, hundreds of thousands lines". I guess it means the code is more than 100k lines. What's funny is he said the art took most of his time. Not programming.

>>105810562
people didn't write muds from scratch, they just configured open source mud servers and added custom scripts/content

>>105811084
doesnr look very good desu

>>105811084
This might shock you anon, but if you actually have decades of professional game programming experience, it's not exactly difficult to shit out a indie tier game engine. Also that looks like shit.

>>105810484
You can learn a lot from just doing 2D, 3D isn't the problem, there is so much 3D open source code out there that you can borrow and use, going from nvidia examples to random MIT licensed game engines, even like the physics SDK libraries have their own example vulkan / etc demos that aren't very complex at all.
Raylib for example just draws 3D models, it doesn't need to be more complex than that, you don't even need LOD levels or frustrum culling if your models are low poly / good retopology (but it's a huge FPS benefit if you did).
You are more likely to be filtered by game code, because it's a trade secret.
Good luck finding good game code in the world where google sucks, AI content farms from india are everywhere (Indians LOVE C++), and reading open source projects requires a huge amount of skill (reading other people's code is a skill you need to develop, and C++ is probably one of the most FUCKED languages in terms of how every project has it's own style, and every game has spaghetti code, ECS is spaghetti, monolithic entities are spaghetti, everything is spaghetti).
So uhh, make a 2d game and learn UI and saving / loading and game loop shit and hopefully you can hopefully avoid a few mistakes you made when you start on the 3d game.
You can make a 2d game with opengl easily (just have one big VBO and just draw the triangles onto it, you can look at raylib / SDL's code to see how they do the 2D api, note your VBO can't be batched AKA drawn in one call if you change textures or call GL functions which is why sprite sheets help, opengl 1.1 is EASIER for 2D but why bother), but note that SDL is more portable and since it uses DX11, it has faster fullscreen alt tabbing (opengl will flicker the screen black for half a second when you alt tab, and overlays such as volume will not appear BUT the steam overlay will work fine, this can be fixed on a nvidia control panel and set opengl/vulkan swapchain presentation mode to dxgi, this is just autism however).

>>105806327
Apple chads win AGAIN

>>105811084
>custom engine in C/C++ written from scratch, no frameworks used
Is this some kind of flex? Millions of people have written games just using C/C++ and assorted libraries. Game's a Windows exclusive from the looks of it so I would assume it's built on DirectX which just outright includes all functionality you need to build a complete game.

Not polished yet but working demo. Pathfinding is integrated to the spatial hash. And that is integrated with the networking. Showing a spell with astar pathfinding. The spatial hash updates subscribers on collisions, and also might cause the spell to collide at said point before reaching goal point (eg rock smash there if enemy).

Should I use Vulkan instead of OpenGL?
I *want* to use OpenGL, but I'm afraid it's gonna be 100% deprecated soon, and that the Switch 2's SDK dropped support for GL 4.5 (which was supported in the Switch 1's SDK) should I port to Switch 1/2

>>105813198

For indies, yes. As an example, the creator of Axion Verge said his Wii U port sold more than his Xbone and PS4 ports combined. And this was when the Switch was already out. Xbone and PlayStation are for normies to play FIFA, CoD, and Just Dance; they don't play indies on them.

hahaha no

>>105814281
you can have a full map and sprites moving around on the nes in a few hundred lines of assembly, now do that in vulkan or dx, the shader alone would take more lines of code

>>105814293
that's an unfair comparison, do it with raylib instead

I want my engine to use phong lighting but for shadows I want to use ray tracing to avoid shadow maps entirely. Although I wouldn’t render them at full resolution. Reflections would just be cubemaps.

Thousands of games have been written in C.

If you're thinking about using OOP for your entities, you can just have a generic entity struct that contains an enum type (player, enemy, static thing, whatever you need), and a void pointer to some arbitrary data for the type to use. Then when you update/render your entities you just switch on the type, call a specific function for each type, and inside each function cast the data to whatever you set on it for that type to do type-specific stuff.

He also claims his engine is currently 14x faster than Unity… but on my machines, his is about 20% faster, and 25% slower than Godot. He also has some serious bug, because frametimes double after 5-10s.

>>105815958
theres really no reason to do this instead of using C++

Vulkan is also depracated because of the descriptor crap, which was designed for cards in 2015 not 2025. The future of graphics API is the way Metal does it.

I'm finally done with the 'Create with Code' Unity tutorial. Should I do the full pathway or right jump into my own personal little project?

>>105816245
if all you're doing is writing your c++ like it's c but replacing malloc with new and using classes instead of structs+functions, then compile times will be in the same ballpark.
but if you're writing "modern and correct" c++ at bare minimum you're including and and you've already ballooned your compile time to an obscene degree, relatively speaking.
god help you if you start using vectors maps and lists to hold your data.

descriptors were never designed for actual cards, in the descriptor buffers announcement khronos said they were designed as an opaque abstraction that could support the edge case of shitty chinese mobile gpus without real registers so they could pretend they had registers while also supporting real gpus
descriptors were just abstractions over device side pointers and config structs in a variety of locations on real hardware

If Diablo was turn-based it would be a long forgotten game

>>105817204
there are a lot of turn based looter games that are just as addicting, if not more. if anything the big issue with diablo has always been how awkward it feels to play for an action RPG. same issue with MOBAs essentially. something like a single player diablo that played like a good infinity engine game would've printed money back in the day.

>>105817509
If Diablo was turn based it would just be another shallow 90s dungeon crawler of which there are thousands
Making it real time invented a genre

>>105817526
none would've had the loot system diablo 1 did. if you took random loot and multiplied the dopamine by 4 due to party management you would've had a hit, albeit a more autistic one. I know because japanese blobbers essentially do this in first person and they're very fucking addicting.

>>105817558
What do you mean loot system? You think other RPGs didn't have loot?

>>105817566
affixes are a pretty unique property for loot in diablo 1 that makes all the difference. it makes the game replayable as you hunt for better magic items to strengthen your character build by killing, killing and killing until you get magic items that best fit what you're looking for. I'm also not sure what other games before it did anything similar

>>105817640
Maybe you're thinking of Diablo 2
Diablo 1 was very basic

>>105817648
it's not that basic upon replays. it'd also fit a turn based dungeon crawler where you control an entire party. diablo 2 expanded the idea massively though yeah

How do you draw a window?

>>105817749
glfw?

>>105817773
Ok so SDL does the exact same thing, people use it for the same reason you use GLFW.

>>105817744
It abstracts some platform-dependent functionality like window creation so you can more easily make an application work on multiple platforms. e.g. you can use SDL input/output functions to read files from a directory on windows/linux, but you also can use them to read files from your APK on android platforms without having to deal with writing the code to interface with the android API because that code is already written on the SDL side and provided to you as an identical interface to the one you use on windows/linux.

>>105818709
I'm sure there is books on it. Many programming courses use game systems as learning examples. You could also take a look at GDC talks of games you like. They can get quiet in-depth. I remember the talk on Assassin's Creed 3, giving very detailed instructions on how to build season and weather systems, for example.

i'm goint to make my engine to only use the CPU, no GPU nonsense. Nowadays you can do a lot drawing on the CPU. In the future GPUs will not be required anymore

Has anyone ever used a vector art library in c++? I want to make a game that is visually similar to gif.

There are libraries like nanovg and cairo but they are ancient. That doesn't necessarily mean they are bad but I'm still looking around. I don't plan on using any svg files, just code to draw shapes.

i'm rewriting nanovg in c#. drawing convex polygons is fast (rects, circles etc). but on large scenes glBufferData becomes the bottleneck, because it generates a lot of vertices and large uniforms.

>>105823401
if you are hitting glBufferData bottlenecks it might be time to look using cutting edge OpenGL features from 2014

>>105823401
Why do web fags have all the good vector tools? I'm almost tempted to make my game in a browser. But I want to use box2D and my game might be physics heavy and I want the performance. Plus I'm used to c++ and I want my game to be standalone and not rely on a browser or electronjs or whatever.

The documentation for nanovg really really sucks (but I guess all of them do). And I don't think it has clipping other than basic rectangle. I need that.

I have 6 months to come up with at least 2k in cash or my neetdom ends and I have to go back to wageslavery which puts me into clinical psychosis (Almost killed a coworker cause I thought they were some entity transmitting pain into my brain and stealing my thoughts). What's the most realistic type of game I can make in that time to make that much? I can already draw 2d assets and basic behavior with raylib. Would the best bet really be something like a visual novel? Wish I could focus on the bigger ideas I have but those would take years, years I don't have.

It is with excessive amounts of optimization. Here’s an indie game that uses path tracing https://store.steampowered.com/app/2941660/Archean/

>>105823655
it's not that that bad. i have ~200 FPS with 5000 circles. most of rendering time is dealing with buffers, though

>I don't think it has clipping other than basic rectangle
i think it's possible to achieve with stencil mask.

I got FLAC decoding working now
Is it really that difficult to encode an Opus file?

When drawing UI elements for a custom GUI, should I procedurally draw the elements all from a shader at runtime (no textures, just take a quad and apply fragment shaders to it, rounding it, giving it gradients, and so on), or should I just use textures?

>>105826004
I use a combination of both
It can display textures but the shader has a bunch of options you can apply like photoshop layer effects

>>105826004
Either and both are valid.

>>105823401
rust

>>105823655
Not anon, but you can compile C++ for the web as well as box2D using emscripten.
But you will need to use javascript for cleaning up certain stuff related to JS (the default emscripten html style is very barebones). And there are a lot of things you need to figure out along the way since there's a big difference between native apps and web apps (for example, testing your program through emrun may not work the same as running it on a real website like itch.io or github pages, for example most websites don't give a special cross origin security header thing which you need for sub 1~ millisecond timer resolution and for shared memory for multithreading because of spectral/meltdown exploits, you would need to host the website yourself and manually add the special header to make it work.

I don't understand why people say "modern computers aren't suited for vector graphics." Isn't 3D vector based? Yeah everything gets rasterized but all models are comprised of vectors.

>watch tutorials like Unreal sensei to familiarize myself with the engine
>learn blueprints and eventually C++ coding
>watch blender tutorials

Would that be a resonnable roadmap for the next 6 months? What else would you add? What are the most thorough tutorials, like the ones that go into details?

>>105830907

They are all scams and waste of time. Just make the game you want to make instead of competing against fakers with years of experience who just tweak an existing project to fit the theme.

>>105830907
Pretty much what I did but I started with Unreal 4.17. I didn’t do any game jams though.

Unless you really get into sculpting a tablet is completely worthless.

Is there any way to make compiling and handling libraries/packages in c++ not such a bitch? I use vscode and they have generators for makefile boilerplate but I still have to manually add libraries and folders and paths. I've never had to do this for any other language, it usually just knows. And the run button never works the way I want it to. It only runs the current open cpp file. I have to type 'make' and then './exe' in the debugger every time I want to test my game.

What image editor do you guys use for textures and UI elements and the like?

>>105833185
Krita. It's the only image tool on Troonix that doesn't suck fat major fat balls. It does take some time learning, though.

>>105833017
>make compiling and handling libraries/packages in c++ not such a bitch

Best I've seen is to just have a local vcpkg for your project and -I/-L the install dir
Highly recommend taking another look at CMake though if you haven't in a while. VSCode support for it is especially helpful.

>>105833017
yea use cmake and find_package with pkgconfig support optionally with a package manager like vcpkg and not make like a boomer
usually it's just as simple as find_package(SDL3 REQUIRED) then target_link_library(buildableThingName PRIVATE SDL3::SDL3)
the only pain in the ass is that there's no enforced naming conventions for the fake library you link to which sets up linking to all the real package libraries, finding all the headers, paths, and binaries and it's not even required

alternatively i think meson has proper integration with the conan package manager

>>105833017
on linux the package manager is good enough for the distro you use.
but on windows you would just use vcpkg, mainly because it copies the DLL's to the exe (if you only point includes it will not copy the DLL's for you)
also stop using mingw, it doesn't have address sanitizer which is the only debugging tool you need, warning and compiler built-in's are half pointless.
if you care about warnings as a way of enforcing style, I suggest using clion which is free for the non-commercial use license (it has every single warning you could imagine and it's annoying, but you can turn each one off), and in theory it has cmake automation stuff but I have not used it much (like add a new file to the cmake project).
Vcpkg classic mode uses less space on your filesystem since libraries (SDL) can easily add up to like 100mb+ per project with the manifest mode.
I use cmake presets to add a asan build, but I think clion has it's own project format I think? (It still uses cmake). But the preset file is neat if you want to switch between clion/vscode/VS seamlessly with the same folder structure (I tend to need to do a clean build when I switch).
I personally use address sanitizer only for the code I build, but vcpkg does have the option to build all the libraries with address sanitizer if you use a vcpkg overlay port.
You also need to set a global variable in advanced settings -> global enviroment variables to enable JIT debugging with asan ASAN_VCASAN_DEBUGGING OR you could make asan create a core dump ASAN_SAVE_DUMPS.
Also if you really hate msvc due to the flags, you could in theory use clang-cl, but it doesn't work with address sanitizer with vcpkg because vcpkg will always build debug libraries with incompatible flags on a debug build for clang-cl (also clang-cl asan wont work with the debugger, it will just exit the application).
also the default debug cmake settings for msvc will give warnings for address sanitizer due to incompatible flags (it still works).

Oh yeah we're going places

>>105829286
that's like html canvas clip(). it renders polygon into stencil buffer.
nanovg uses this technique https://web.archive.org/web/20190216142654/http://www.glprogramming.com/red/chapter14.html#name13 so it already renders polygons into stencil buffer. the trick is to use stencil bitmasking features (a combination of glStencilMask() and glStencilFunc() mask parameter) to keep clip mask in stencil buffer while also using it to render polygons.

thats how i do it too

>>105808142
>something like raylib for common lisp would be good though

Ubershaders. Yay or nay?

>>105834499
Conditional shader compilation is common in the industry. It keeps render pipelines nice and tidy

>>105834499
I was in nay camp until I was able to reduce 30 shaders down to a single one with some #ifdef blocks im thinking yay

how to shaders

>>105824815
i tested with 5000 stars and perofrmance drops to ~90FPS.
it's OK to render GUI, but it's really not suitable to use canvas to draw every game frame from scratch. some sort of rendering to texture caching is needed.

>>105833241
What I really liked about exploring Krita for the first time was how reasonable everything was, "filter layers wow very cool", and then you click on the little teensy brush editor button and it's like Alice in Wonderland falling into a Bosch painting of ZynAddSubFX.
