first for procrastinating out of fear for the complexity of the next feature you need to code
Second for massively overcomplicating your life by following weird ideas you found on Digital Grove which sounded great in theory but turned out much harder in practice.
trying to recreate the shader from youtube vid rel entirely as a post processing inside Unity 6 SRP.on the surface shader, its not a regular shader, and instead outputs 3 channels for data. which is also why the guy is pink at the start, but the rest are black, I still need to improve the channel information that is sent from here to the post process.this lets me use a gradient texture inside the post process, to determine how is he colored and how to use more than one color for my entitiesthen there's a separate pass to project noisy textures, and is how the guy has stable noise on his body, whereas the rest of the scene uses easier to set up triplanar textures.here is the video i am trying to base my style after:https://www.youtube.com/watch?v=xmS5aQEA1XwI think overall, as a post process, it's cool. I think the effect would be a little easier if I set it up as regular surface materials with _GLOBAL properties and control from a script or something.Also, I dont know how he did that 16-directions rotations for the one guy who has quantized rotations in the video. Tried my best, but I'm no good at quaternions.do you like this? would you play a game like this? My goal with this style is to recreate the old Nintendo Power Legend of Zelda art paintings by Katsuya Terada, combined with comic books style like HellBoy
Finally got somewhat decent detection of overpass roads and able to color the underpass road and lane dashes differently than the rest of the path.Testing with 3 varying elevations with road rendered on a single path.Am I insane to try to render everything?Because I like kt better and it is making the full game dev way easier down the road.>>108473375This looks cool. The guy even has /g/ forward head posture.
People who are doing things in DX12/Vulkan, did you start out with higher level APIs?
>>108473259Ah, the ol' one-two Blow-Muratori knockout combo>>108473772No, I dove straight in. I didn't make my own engine to rely on black box APIs, so I didn't want to use pre-12 DX or OpenGL. Having to deal with the driver being a black box is already annoying enough, don't need another layer.
>>108473772yeah
If you could go back to college what major would you pick if you're into game dev?
>>108474163CS major then take some music, writing and drawing and 3D animations extra private classes.
>>108474163There is no if, I'm in the middle of doing an online compsci degree at age 32.
>>108474163Nothing, you will learn more by yourself and it's free
>>108474163fuck that would be a waste of time and money
>>108474163You don’t need an education for video game development. Just lots of patience.Brush up on your math skills.
>>108473772i had previous experience with dx 10 and 11 before i jumped into dx 12
>>108474163nothing, i have no talent for art and the cs course was a fucking joke, practically didnt read anything at all and still got great marks
>>108474163A gamedev major. My country has a few decent ones actually.>waste of timeTechnically yes, but you're doing it for the line on your curriculum. Though the biggest would probably be just starting with programming 10-15 years earlier.
>>108472901What extension does Valve, Qcom and Android have for gamedev?
>>108474288what
>>108474288I was just going to post a link to the Vulkan registry, but for some stupid reason, they removed the extension specification list off of there.Well, I guess you have to look in the actual docs now: https://docs.vulkan.org/spec/latest/appendices/extensions.html
>>108474163if I went back to college I'd do the same thing (take CS) but i'd cling onto my Graphics Programming professor and pester him for industry connections instead of being an asocial incel freak who only cares about passing assessments and exams
>>108474380Industry connections for making indie games?
>>108474393industry connections for graphics programming gigs, like engine development
>>108474346>read these whitepapersfuck off
>>108474415Why would you want that when you're making your own game?
>>108474346https://vulkan.gpuinfo.org/listextensions.php?age=historic&apiversion=all
>>108474420are you retarded? hes talking about how things could have played out, getting an industry gig right out of uni. not to mention lots of people who works in the industry have hobby projects
slopes working again
>>108473462thanks, its a model called Unity ADAM. usually I'll use robot kyle (pic) or a spiderman model for working on shaders but I used this ADAM one cus the video I wanna recreate is using it too>>108474163I would not go at all. Costs too much $$$ and I still owe them $$$, and even with the $$ I spent, I cannot get a job that will pay enough to repay them.
>>108474501realtime rendering discord poster
>>108474501What's the trick behind 6dof in a raycaster?Also how did you implement such good-looking slopes? Any resources?
>>108473772Nope. I figured I was going to learn Vulkan anyway and just made the deep dive. It was rough at first but very much worth it.
>>108474517its tricky as fuck, and honestly I still don't 100% understand it.https://github.com/sp4cerat/RLE-based-Voxel-Raycasting/blob/master/Paper.Efficient%20High-Quality%20GPU-Based%20Visualization%20of%20Voxelized%20Surface%20Data.pdfthis should help give you an ideathe main trick is that you split up the world into 90 degree quadrants in world space, and map those to different offscreen buffers, which allows you to raycast to contiguous columns, for performance.you then map those offscreen buffers onto the screenspace area covered by the world-space quadrants. voxlap is very similar to this (although with voxels instead) but it's clearly different in the way it maps the quadrant buffers back onto the screen (and it uses a ton of hand optimized assembly, allowing it to run on a pentium 3..)>>108474517the trick that makes them very easy is texturing floors/ceilings in vertical columns rather than horizontal rows. you lose the constant-depth benefit, which means a division+mult per pixel, but modern cpus seem to handle that no problem.you simply project the calculated start and end height of a slope for a given ray intersection, and fill texture between those.
>>108474417In reality, most extensions that aren't *-KHR aren't super relevant to most general use cases.
I lost, I fucking lost guys what the fuck
>>108474417Sorry, Vulkan is whites only.
>>108473772Started out with OpenGL ES 2, then went to Vulkan 1.1 years later.
>>108474622Except nvidia owns 95% of the GPU market on PC. You'd be retarded to skip over their extensions, especially when most of their extensions get officially adopted eventually and you'd have 90% of the work done by implementing their extensions. Like the entire raytracing API for vulkan, mesh shader extensions, DGC extensions, etc. Even when they're not 1:1 you'll still have most of the world done
>>108474663Hey can you be more respectful?
>>108474631the game? me too.
>>108474708Fuck you.I went 15 years. I just lost the game
>>108474663Using extensions is risky business.Either you- Literally lock yourself to a vendor, or even worse, a specific generation of cards: which is fucking retarded if you're making anything you intend someone else to use and you're literally not targeting a single console.- Have to create multiple code paths with an exponential growth of configurations which may or may not be present, which massively increases code complexity and makes it far harder to test.If you're a big studio with the resources and the need to actually truly push maximum performance, maybe the 2nd option is viable, but lets be real, you're not.With the really big "fundamental" shit like ray tracing or mesh shaders, the answer is always to wait for the KHR version to come out.
>>108473375Pretty cool>Also, I dont know how he did that 16-directions rotations for the one guy who has quantized rotations in the video.Someone made a tool that does that in UE4, so I'd suggest you try finding that and see if you can rework it for unity.
more progress, chuds.
>>108474988>NimBased Wirthian Chad
I just realize I can use a system similar like mugen where I store each animation inside something like anims/idle where each folder is a substate animation.Then on the JSON of the player I just need a seq[string] to store the animations, while are just filepaths to the subfolders inside player.Then I just on my player just hold a 2D array of textures.And then I just loop then as an animated sprite in naylib.And then add some basic reserved keywords like IDLE, WALK, WALK_F, WALK_FD, WALK_B.Or maybe store all the directions of WALK inside a folder called WALK and then each direction is just WALK/F, WALK/BThat way adding newer states only requires to add newer folders and inside the .webp and a basic edit to the JSON.It would be much much easier and simpler than all the autismo of godot and unity.

>>108447717*yap:Issues I found with llvm-mingw using pdb files:-C++ types in libc++ are not visualized by debuggers, someone made a .natvis libc++ visualizer for chromium, so I just renamed std::__Cr with std::__1 and it worked.-vcpkg wont copy the pdb files for me (locally it will still work because the pdb path is hardcoded in the DLL, it also saves disk space).-LLVM 22.1.0 added in a feature for if you use ubsan to output formatted errors with traps enabled. Usually traps are vague and unhelpful, but with __builtin_verbose_trap it will store the message on the stack. This does not work with pdb files (including msvc clang, llvm installer). Also the __builtin_verbose_trap will not work if you use -g or -gline-tables-only. Meanwhile a release build without debug info will still have functioning stack traces. (on msvc/msvc clang you need a stripped PDB...) But the debug trap is not a real function, so it shouldn't exist on the non-debug section (it always appears as inlined).So... just re-implemented ubsan using the micro ubsan bsd code (so that I can use it for making reports, I might try minimal ubsan for production). And I will use msvc/msvc-clang because of cleaner stacktrace code, the binary size is much smaller, and iterator checks. (msvc is slower to build + no colors in my errors, but msvc-clang is not perfect with optimized debug info... BUT that's a nitpick).Also it seems like llvm combines ubsan's runtime with asan's runtime, but that breaks my custom ubsan runtime with duplicate symbols... Asan already has a callback I can report with, but not ubsan.>>108447096>llvm-mingw defaults ALSR off (for addr2line?) so I add link: -Wl,--dynamicbase,--high-entropy-va,--nxcompat,--large-address-awareI was wrong, ASLR is on, this isn't a recent change or anything. The other flags are already enabled.Also libc++ on llvm-mingw is built with cfg guard, not particularly interesting (I use cfi-san) but that's not vcpkg's default. I used PESecurity to check.
>>108475534That's what 'programmer art' is for.
>>108476262What is it about build systems that cause people to write paragraphs and paragraphs of useless information
>>108475534https://perchance.org/free-text-to-image-unfilteredIt doesn't have to be good. it doesn't have to be permanent. It just has to be.If you're after 3d models, then the default blender shapes, and mixamo models are your best friends.
>>108476411>>108475534kenney assets are decent enough too. pretty sure there are 2d and 3d packs on his website.
I'm so happy now, chuddies.
>>108473259Which ones?
How would someone who knows what they're doing in OpenGL make a way to blend two different textures in a smooth gradient, kind of like how there's a smooth mix of colors in the Hello Triangle?Followup question, is it even worth it to bother? Is it just unnecessary fluff to a shader program that could be better done with less intrusive methods?
>>108477308sample 2 textures and use mix()
>>108477335That was my initial thought.Right now I'm trying to troubleshoot an implementation where my vertex shader has texture coordinates, an index to texture 1, texture 2, and a float to be interpolated through the fragment shader. I'm using a 2D texture array to store an atlas of sprites to change between.It's kind of a lot to send to every vertex of a mesh, in addition to stuff like position data and color change. Or maybe it's not that much, I don't know.
>>108477308>fluff to a shader program> less intrusive methodsyou have no idea how this works
Putting cube in world using CHICKEN.Probably will need a few helper fucntions to shorten the time.I've shown this before with the old engine. But now at this point I can say the new engine has caught up with the old engine.Time to move on with new things.
>>108477335ok, done troubleshooting it. here's what it looks like when it's working well. Still not sure if I want something else for this.>>108477354if I did, I wouldn't have specifically asked for "someone who knows what they're doing in OpenGL"I know that I don't want to send mountains of data to the GPU for each vertex every time I load up a VBO. And I don't want to go out of my way to create some convoluted way to achieve something that someone else already thought up an easier way to do years ago.blah blah premature optimization, yadda yadda, getting it working is more important than getting it working well.I know, but I also know that I want to learn it right.
>>108477383Shaders is the least intrusive way to do any graphical effectYou aren't "sending mountains of data" you're sending a single value per vertex
>>108477391do you mean in this context, or just in general? how is it a single value when you can have many different attributes in your buffers?I'm not even trying to be snide about this, I'm actually asking. one of the first bits of advice I heard was to watch how much you're sending to the GPU.
>>108477405How are you determining the blend value? Either you do it algorithmically in the shader and you don't need a blend value, or you send one in
>>108477419I was already sending an int for the texture layer, and now I'm also sending another int for the second layer, and a float for the blend value.It might not be a lot, but it'll certainly add up, and I want to at least be efficient where I can.Before I had the idea to do this, I was trying to find an easy-ish way to not have to send that same layer int to every vertex when I could instead send it to each polygon drawn. Also considering if that was even worth the effort.
>>108477444There's no per-polygon attributes you only have per-vertexI take it you're trying to make a multilayered terrain, I send an entire color (RGB) aswell as the blend value for every vertexSomeone told you " watch how much you're sending to the GPU" but they didn't give you any metrics so now you're trying to your absolute hardest to save memory like a dumbassDo the math, look how much memory your GPU has, look how much memory a vertex takes and how big your terrain is, you can afford more, my regular mesh format uses 64 bytes a vertex
>>108477457y'know what, fair enough. It's not like I'm going to be making a graphical powerhouse or anything. It's even designed to mimic the style of old games from the 90s.I'm not all that concerned about this specific thing taking up too much video memory, or tanking the transfer rates between the motherboard and GPU or anything. I was just wondering if there was a bit more of a popular and efficient method for doing this.

It took some fiddling with Slang but I finally got vk_ext_descritptor_heap working in its entirety, along with shader objects. No more pipelines, pipeline layouts, descriptor sets. I no longer use the primitive (set = 0, binding = 0) that you midwits use. Everything in the shader is accessed via DescriptorHandle<T>.

That is always going to be slow. We're just at the point that $2000 GPUs with dedicated hardware for it can do it at 30fps.

Considering the fact that the AMD AI max has an npu that has the same flops as it's APU (which is roughly the same as a 4060), could it be possible to use it for something that isn't AI?I looked at the MLIR and the architecture of the Xilinix AIE that's used in the NPU's and it seems like absolute hell and you need to think about the instructions and memory in terms of tiles and the various ways of communicating between the tiles.I was thinking maybe since the tiles are laid out in a 2d grid, could that be used for a 2D map, like lets say a falling sand game? I wouldn't want users to NEED an AMD AI npu, but like what if I had a tile grid that was super coarse BIG pixels, but if you had an AI npu, I could make the pixels be 10x smaller or something. I also saw llvm offloading, but I think it wouldn't work well with NPU's (at least AMD's, I have not looked at intel's npu), and NPU's are kind of neat because they "should not" affect the performance of GPU rendering as much as a compute shader / Cuda/ etc.
How do you guys get into the groove to work on your game, knowing it's going well, but being so drained from programming as a day job? It's the weekend, and I've slacked off so hard on the internet.

>>108483096>>108482592stop trying as hard at work or work on your game during work hours if you can get away with it.i keep a pocket notebook with me while im at work and write down ideas for how to solve problems i'm having with my game, a to-do list for after work, and general ideas about what i want to do when i have more free time.it's nice to have a physical representation of my game while i'm away from home. and since its a notebook with no backspace or anything like that, and all i can do is add to it by writing things down, it feels like a constant forward momentum even if its all in my head.basically gotta work on it a little bit here and there during the week before or after work. then on your days off, the idea of jumping back in isn't as daunting, you'll already have things that are in-progress from earlier in the week, and things written down on your to-do list.best way to get into a groove and maintain it is to keep things moving, even if you gotta slow down for 5 days of the week its better than some start stop bullshit.then take a complete break once or twice a week where at most you only write things down. i use break days like that for writing down a more generalized to-do of things that need work, and then over the next week or two thats I'm keeping in mind when writing down stuff in the pocket notebook, game devving when I get home from work, and on days off.
>>108483534>then take a complete break once or twice a weekoops meant once a week, or every other week.
How do you get video files smaller than 4MB?I tried using OBS. it always looks like a blurry mess, and still comes out too big, even with 640x480 resolution and a length of only a few seconds.I want to show my rolling field of Konas buzzing around in circles. They all follow the terrain, and turn their mesh to face the camera at all times. Also there are over a thousand of them, and the lowest the framerate has dropped is around 100.
>>108479746use ispc
>>108482470problem with using any npu is documentation and lack of hardware support in open source drivers. Its a scam since they advertise features you cannot use even with their in house tool chain. I am quite sure the npu will have the same problem as offloading to the apu the transfer cost itself makes it not worth it for anything complex.
>>108483707Record in high quality in OBS, run it through ffmpeg (or some frontend to it) to cut it down massively and fit under 4MB.Getting realtime high quality yet small file size recordings usually isn't going to happen.
>>108484419yeah, this. real time encodes don't have the time budget for much optimization, but ffmpeg can squeeze it down and take as much time as it needs
Things look a little glitchy but I'm pretty sure its mostly because of the interpolated frames between update ticks. I've faced this kind of problem before where an interpolated frame setup doesn't take to kindly to teleportation.Here is a basic animation test. You can adjust speed and do looping. Made with 5 translation key frames and 2 rotation key frames.
Not sure if it was discussed already, but the Slug algorithm for text rendering is now public domain. Kind of a big deal.

>>108487029The first time I tried a Vulkan engine was when /gedg/ started. I went on a pretty big hiatus because of grad school and would post my other projects occasionally. They never really led to anything though.
>>108487029>2 years to upgrade to 3d cubeEh last thing I remember on that engine was that I was able to generate a cube world and I was using lua scripts to alter the 3d generated world. I also had A* pathfinding on the cube world.
What is a command buffer?
Do u play your own game everyday and get hooked just like when you play other people's game?

/gedg/ is my new home from now on, not posting onto /v/ game dev threads anymore after today. >>108487277in Unity its a command you send to the gpu for rendering at certain parts of the pipeline. so say you want to make a stealth game, and use a mesh for your shadows instead of something on the fragment shader, since its a realtime thing that mesh might need to be somewhat dynamicso you could do shadow calculations for your atten, and then use the command buffer to push the instruction for how and when to draw the mesh for shadows.

>made a full 3d engine in flash back in the day with 0 knowledge or experience>can't even find the motivation to make a 2d engine in raylib now
Is it more "correct" to have one shader that can do many things, or multiple shaders that can do one thing each?so, would it be fine to have one shader for meshes and terrain, one for particles, and one for UI? Or is it better to not have to keep switching between them every frame?(OpenGL by the way)
Do you all hate Bevy & Rust?
>>108490637I think large engines get on the level of doing a pipeline per material, which is why modern games can spend literally dozens of minutes compiling shaders on first load. It's not like they actually wrote that many shaders by hand though.But then you have the complete opposite end of the spectrum, where you have ubershaders, but the original example of that was to fix shader recompilation stuttering in an emulator.Really to say, I wouldn't say there is a "correct" solution. Just having a handful of shaders like you're describing is perfectly resonable and sound. I wouldn't say that generating a gorillion shaders is "more correct".
>>108490637>correctngmi if you're even thinking like thatand yes, you should use an ubershader unless you have a good reason not to, branching in shaders doesn't matter if every pixel currently be processed takes the same branch anyways
>>108490710no wonder modern games are so bloated and buggy.>>108490723I put it in quotes for a reason.I'm just trying to figure out some generally accepted wisdom from people who know how the API works.What would constitute a "good reason" in this instance then?I'm not going for some sort of graphical marvel, so I don't think I have to worry, but I'm still curious.I'll probably just stick to my ubershader in this instance.
>>108485687It depends. If it's an average software dev job, then it should be fine and can actually boost your productivity with work as well. Because your brain gets more stimulated this way and helps to not be sleepy all day.
is there any free hosting that can handle something basic online gameplay for a small number of users?

>>108491152what about some kind of proxy service where I can host everything myself but not have to directly give out my personal ip?
Claude in computer control mode is ridiculous. I have never made games so fast
>>108491463you can use a VPN with port forwarding
>>108491463Nothing free that'd be even remotely reliable and isn't somehow malicious. The only reason you can even get a free email these days is because the provider farms your data and sells it.
>>108490637one shader that can do many things aka uber shader. That’s why iD software does for Doom and they are able to keep pipelines down to less than a couple hundred. Unreal has pipeline explosion because making a new material means making a new hlsl shader which means making a new pipeline. So there is technically an infinite number of potential pipelines. Ideally you want to be not totally dynamic like Unreal and keep as much logic as possible packed together hence uber shaders.
Have any of you guys implemented multiplayer in one of your games? If so, what are your standard practices? Do you implement listen server or dedicated server? Saving to disk or to database? And do you use a modern replication module?
>>108491982Is also like to hear more about this
I am happiest when working on graphics code and C++. When I get into a flow working on some stupid little graphics or linear algebra problem, I feel invincible. But the entire goddamned world keeps getting in the way of that. Work problems, life problems, family problems. Everything is trying to keep me from doing the one thing that makes me happy
>>108492656I sorta know that feel, but I'm a bit of a math retard... for now.
>>108492687So was I. 1.7 GPA in high school, failed my way up through community college, transfer to and dropped out of big boy college after getting filtered by calculus 3 times.But somehow, when I need math for graphics/physics/engine dev, it's easy. I guess calculus was never hard, it was just hard to convince myself to go to class
>>108492656Why you post Romero and not Carmack though. Romero is le lazy art/mapping dude, Carmack is turboautism engine/graphics programmer. Carmack fired Romero because he was too lazy and had too much fun at workplace. Romero is cool af too, just less relevant to your post.
>>108492731The cult of John Carmack vastly overstates his technical achievements. Carmack was narrowly focused on visible surface determination during quake's development - they hired other god-tier engineers who were lost to history to handle other graphics and networking tasks. BSPs were not something Carmack invented, just appropriated into the world of real-time rendering.In Romero's telling, Carmack basically started to lose his mind during the development of Quake because he was cracking under the pressure. Carmack prides himself on his "work ethic" but the reality is that he was struggling heavily with VST because he wasn't sleeping, wasn't exercising, and survived on a diet of pizza and diet coke. As a result, he began lashing out at his coworkers, who had to put up with his shit because he was their engine guy. You can get a lot more thinking and working done when you drink water and get enough sleep.Also Carmack is an AI grifter now
>>108492731>Carmack fired Romero because he was too lazy and had too much fun at workplaceThis is a falsehood from "Masters of Doom". Romero was forced out because Carmack thought that Romero should have been spending 100% of his time on quake instead of project managing Heretic, Hexen, Master Levels, Final Doom, and Dwango. Carmack believes that companies should basically only make one thing, while Romero wanted to grow the company and diversify their income. I don't even think Carmack disputes this. Masters of Doom contains about a dozen factual errors and this is one of them.
>>108491982I did implement the technology for multiplayer, tested it with multiple simultaneous clients, but my current game is not meant for multiple players.
>>108492775>Also Carmack is an AI grifter nowWhat's he actually working on? He was talking about it like it was the way of the future on that dudes podcast, but I i never actually looked into it.
>>108493150Last I heard he was training AI to play atari games or some shit. How the mighty have fallen.
>>108494068If I had his money, I'd probably do stupid shit too. People will throw tens of millions at whatever he wants to waste his time doing, so he might as well get real weird with it.
>>108472901I found a WIP indie game someone shared with me 12 years ago. It was a fully playable level 1 demo and they gave me the project files, not just an executable.

>>108494543>>108494636>source 2 engineI'd imagine its 2D is pretty weak?
>>108494543Nobody would use Source 2 even if they released the full thing. It would be at least a decade behind Unity and Unreal in terms of tooling, which is what really matters to developers.
>>108494839I'm not sure what you mean, Source 2 is just the backend engine, S&box is a whole IDE just like UE5/Unity, people have already been making games with it for years but you weren't able to release games standalone
>>108494873That's even more of a non-starter because it's going up against Roblox. Fortnite tried it with a concurrent player count that was a third of Steam's total online users at the time and it did nothing to even shake Roblox. Aside from that I would steer well clear of anything that Garry Newman has his pudgy fingers in. He's an insecure faggot who will fuck over his own product to spite people he's butthurt at.
>>108494917are you not able to read or something?
>>108494917>Roblox???I don't think you're following m8, they negotiated a new license with Valve and now you can build standalone games and sell them completely royalty free
>>108494936>>108494950There's nothing new here, it's just another shitty toolset like Roblox and Fornite Metaverse (or whatever the fuck it was called), not even a proper engine (I highly doubt you get access to Source 2's source code). All you'll do is waste time on yet another novelty that will bring no fruit.Stop trying to find the latest "tech stack" and get back to actually working on your engine, there's no magic solution coming to save you from having to work your ass off.
>>108494962concession accepted
>>108494962Bruh, take your meds, it's a full game engine just like UE5/Unity except royalty freeI'm sorry that this is happening to you
>>108494970>>108494983he's a mad pedot user who just realized that he wasted years of his life on a deadend engine
>>108494983Great, and you had Unity and Unreal available for over a decade before this. How much did that help you? Aside from this being a thread about engine development, there's also no point in chasing new tech like you do. Obviously you think this will help you create your game or whatever, but there are established solutions that have been available for years and you could have done whatever you expect to do in S&Box there and be years into development by now. You didn't do it, they didn't help you, you do not need yet another layer on your "stack". You need to stop looking at this kind of magic solution bullshit and start working on your actual fucking game.>>108494995I like how you assume I'm working in fucking Godot in a thread specifically made because people working on their engines didn't want to go to /agdg/. And this is exactly the kind of mindset that is pervasive in /agdg/: "just one more engine/plugin/LLM/workflow/DCC/whatever and I'll finally make my game!". Shut up and start programming, retard.Also>royalty freeAre you allowed to release it outside of Steam? Because otherwise it has the by far highest royalties of any engine/framework/toolset.

Is there anything worse than when you're playing a game then all of a sudden this shitty minigame is forced upon you?
I'm slowly cobbling together a game in C with the standard libraries, because I enjoy reinventing the wheelI'm using a sparse set ECS for all of my data, but I'm not sure how best to "disable" entities. When the player goes to the next level, should I systematically delete the data for the enemies from the previous level? Flag the data as disabled and have the systems skip over it? Copy the player's data into new memory and free the rest?I don't have a CS background and am learning as I go, this is my genuine stupid question and not bait
>>108497355I mean yeah you could just have a list of active entities or something like that. If its relevant to the component data you can also store it there (like maybe you want to do a physics update on a physics component but don't want to draw a mesh component)Depending on the situation you can also just delete the relevant component. Some of my components are just indexs/keys into other data structures.
>>108497355>C>ECS2 strikes, you're on thin ice
>>108497377>If its relevant to the component data you can also store it thereI think I've read about implementations that use the first bit of the id variable as a flag for whether the component is enabled or disabled. I'll see if I can dig that back up>>108497381I did it initially because a stranger on the internet told me ECS good, now that it's starting to take shape I actually quite like it
>>108497355Tear down everything, start from scratch on level load.
>>108497320The main problem with forced minigames to perform repeated tasks is that the minigames rapidly become the core gameplay loop.

>>108499614Yeah, I thought so.I'm trying to work out a bug where the game hard crashes after a minute or so depending on how many models I load in. It happens in about 20 seconds if I load up around 5000 character sprites. (it's a 3d game, they're just billboard sprites)ChatGPT is insistent that I should try loading everything into a single buffer to use in snippets, but then kind of didn't have a good answer for what I should do when I want to remove some data from the middle of that buffer.What point would it be wise to start consolidating? (I'm working on a way to have all billboard sprites use the same model object, but I'm still wondering what's going wrong.)

>>108499716I already said it's 3d and I'm working on a new approach.The new plan I'm thinking of now is to have every cell have one set of buffers for the base terrain, one for the buildings and other static fixtures, and one for the dynamic entities like interact-able items and characters. One cell will be around 512x512 meters since being open world, I can't load everything in all at once.
>>108499740Oh I misreadI don't think it's normal to crash after 20 seconds if you have 5000 models loaded, sounds like some other bugSharing buffers for models isn't really necessary either
