Is programming unironically over?

gamedev turned from cool niche tech hobby/job into slop shop. it's so ubiquitous it became deragotary.
every normie is making "games" now. making a game is the first thought that comes to mind for mediocre people.

don't make games. there are many other software niches you can fullfil. gamedev is full.

I started a new project with Godot, I come from LWJGL and doing shit myself. Unity is fine but I didn't like the paradigms offered, particularly for 2D. Godot seems okay so far but I've never used it and I'm only a day in. Any advice?

Hello anons,
not sure if this is the place to ask or not, but thought I might as well.
I'm almost finished coidng my first actual game, it's like a 10 min visual novel thing
Is there place where I can talk to any artists who wanna collab on this board or elsewhere?
the "collab" is just one sprite and one background
I got some stuff with AI to serve as placeholder, but i don't wanna go with it obviously.
thanks in advance!

I use func_godot. It's maintained by trannies or whatever but I don't care; it just works.

Theoretically how does one get out of "this" stage of game dev?

And how the fuck do you actually code and get over using free assets?

Can you really make a fun game using free assets or do you have to make everything from scratch to have its own flavour.

>>105919609
Have vision.

>>105919609
make what you want, slowly one bit at a time. just keep your scope small as you will underestimate the difficulty of adding what may be perceived as relatively basic things. if I were you I would not even worry about graphics past very basic or free assets. your goal should be to make something functioning and as fun as you can with your limited resources. your goal should not be to make a product to sell; at least not your short term goals.

>>105919678
I once created a horror game in the woods in a valley. It was retro styled graphics. I lost the project because I didnt really care that much and didn't back anything up and also simultaneously gave up because it was too complex to code a flashlight that looked good, as well as rain and thunder I wanted to add in godot.

IMO vision isn't hard coding and artwork limit me.

Random game design question
How would the core gimmick of the classic Monster Rancher games (i.e generating abominations from CDs/DVDs) work in the modern era where digital media reigns supreme?
Take in files from your PC's filesystem? Look at games on your steam library (if a steam game that recaptures the essence of monster rancher can even do that)?

>>105920313
Does it even matter that much? I thought Monster Rancher was about grinding to compete. You could do anything that generates a unique key that then generates a model.

I can absolutely understand the first one with C++, because I work with it and it makes me want to blow my brains out. Which is why I want Jai.
>has worse performance than time tested c++.
Have you actually used C++? Nobody should need to ask why someone wants to move away from C++ if possible.

P.S. Claude 4 understands Jai, at least to some degree, it can output mostly fine syntax (all I've seen was perfectly fine, but my sample size was tiny).
>grok 4 heavy
Worse than all the other top models (Claude, Gemini, DeepSeek) for programming. Though supposedly xAI is working on an LLM meant for coding and Grok isn't, so we'll see.

>>105924062
I get grok to write all the c++ code, aslong as i understand the general flow i don't need to know the specific syntax.

c++ is still the fastest compared to everything else like c# or java

>>105923076
If you're only in it for the money then you were never gonna make it anyway.
Besides, even in that case, having a completed game will certainly look good on one's resume

>>105924114
It's the fastest, but it's also an extremely flawed language with horrid syntax for a lot of things. I'd gladly trade 5-10% speed for much nicer syntax and proper metaprogramming. Right now however you don't have much of a choice, you either use C++ or I guess you can get your balls stomped on by the Rust borrow checker gestapo. I guess Odin is an alternative.
>c# or java
No shit, but nobody is seriously talking about those as a C++ alternative, they are obviously very different languages (unless you're fine with taking relatively massive performance hits).

>>105923451
I've unironically begun learning Odin. It does the needful. I have no idea who or what Jaiis though — sorry. In any case I'm coming from Common Lisp but have done a lot of C and C++ both in the past but was not in the mood for either.

Been a pretty nice experience so far, also switched to Helix from Emacs. Great combo of "just fukken werks".

>>105924018
>has worse performance than time tested c++.
worse how?
C++ is shit when it comes to compilation time. Including a C++ std lib and the compilation time makes you wait for a few seconds, even for a 2-liner "hello world" code. Jai on the other hand compile an entire game within that time and that is not even incremental but a complete compilation.
Both Jai and C++ are LLVM's frontend, Jai having a more simpler and straight forward syntax and features makes it easier for LLVM to implement optimization passes more efficiently than it ever could on C++ code. Jai doesn't have to "come out" for everyone to figure out that Jai is faster than C++. You clearly haven't spent any serious time with C++, stop assuming about its performance.
>>105924590
>ODIN is needful
yes, saar. Can't say the same about you though.
>>105925281
Odin is the C++ flavor of C where the quality of life features are provided with a pinch of Pascal instead of the retarded OOP bs.
You might also find C3(considering both share similar philosophies but different approach) to be of your liking so do consider giving it a try if you feel like Odin isn't for you in the long run.

>>105925479
>odin doesn't have methods
Yes and nothing's stopping you from using function pointers as methods with one additional line, like in C.
In terms of language design, its less cluttered when there is no v-table with syntax sugar that handles that above one additional line for you implicitly.
>>105925500
>insane how anyone can make a modern language like this
While languages like C++ and Rust give more and more, languages like Odin, Jai and C3 give less and less, to the point where they have nothing fancy about their language to market about.
Its not insane. That is how you maintain sanity when seriously programming for the modern hardware.
Modern x86, ARM hardware and GPGPU graphics APIs are complex enough. Having retarded Programming Language complexity on top of that actually makes one loose sanity in no time.

If it really were a basic feature, C would have had it too. Stop crying over pointless things.
Languages like C++ and Java already obfuscated Alan Kay's definition of OOP bad enough. Don't make it worse by pointing out "methods" to be a basic feature of procedural languages. Yes, its comfy to have vitrual tables but not having them is fine too.

How does Odin do with metaprogramming? Some of the stuff I'm working on right now would be 100x easier if I could generate code at compile time easily like Jai does (but Blow has stopped admitting people into beta unless you know and Blow the right people).

>>105926127
>How does Odin do with metaprogramming?
it doesnt

>>105926149
Well I'll wait for Jai then. Since I'm working on a game, not an engine, my code is extremely static and meant to do one thing one way, meaning a lot of stuff is known at compile time. Being able to generate code at compile time would make many many things much easier than C++ is making them.

>>105926183
What do you want codegen for?

>>105926196
The basic underlying system I'm using is an "ECS" (quotation marks because apparently it isn't, but to me it has entities, components, and systems so it's an ECS). Archetypes, queries, observers, etc are all completely static and will never change at runtime, meaning I could generate masks and a bunch of other things at compile time. C++ on the other hand is template hell and massively overcomplicates things, the syntax is barely legible and I dread having to come back to this in 6 months.

It's not impossible in C++ far from it, it would just be a lot cleaner and easier if I could generate code.

>>105926281
>ECS
And no, I'm not making an ECS because I think I need it, I just enjoy that way to reason about things.

>>105926281
Sounds like an unholy mixture of overengineering and premature optimization
A bit of dynamic dispatch is not going to cause a problem

>>105925673
>Simply make game
He clearly states that it was just one out of 70 different proposals they were working on

>>105926183
you need to write your own language, Gay.

>>105926293
>unholy mixture of overengineering
Not really, I tried flecs and EnTT previously and did this because those were just way too much. Effectively I just have instances of predefined sets of components that I iterate over, except instead of telling the system which sets to iterate over, I tell it to iterate over the specific component(s) and it matches that to the appropriate sets.

It would just be cleaner in Jai, but even with C++'s disgusting syntax the whole system is still about 1k lines and is unlikely to ever go above 2k.
>premature optimization
Like I said, I just enjoy this way to reason about it, it's not for performance reasons, if it were I'd just use flecs or EnTT which likely will provide better performance than anything I can reasonably develop on my own while also making a game.

>>105926450
If you're thinking about shit like ECS systems for your game then you are overengineering it
Shifting dynamic dispatch to compile time code generation is an optimization, one that I'm sure isn't neccessary

>>105926450
this wont work. you need to dynamically add/remove components at least. otherwise ecs will be totally useless. this is a cope mechanism to communicate between systems, because there is no other way.

>>105911856
To get from not producing anything to producing something.

>>105926471
>If you're thinking about shit like ECS systems for your game then you are overengineering it
It's really just a way to tell it what to iterate over, it is perhaps a bit of overengineering but your game also has to be something you enjoy working with, and as I said this is my preferred way to think about it, even if it leads to a somewhat more complex system.

As long as it doesn't go overboard.
>>105926488
>you need to dynamically add/remove components at least. otherwise ecs will be totally useles
I can see the use for it don't get me wrong after all almost every ECS does it for a reason, but I don't see how it's mandatory. I know what all my archetypes should look like at compile time, if one might need a component I just throw it in there, most components are tiny enough that it won't really matter if a few entities (in the low hundreds) have an unused component.

>>105926281

if that is your definition of methods then you should have no problem with methods in Odin because Odin has "->" operator for exactly this purpose. Stop crying over pointless shit like a retard already.

>>105926127
>>105926281
>How does Odin do with metaprogramming?
it doesn't do meta programming like Jai does(generics) but you can use Parametric polymorphism to generate code. It does not generate types at runtime but it does generate different variants of code for you at compile time. For your use case, I think parapoly will get the job done.
Here is a simple example on how Odin's linear algebra library generates math function for different types at compile time, depending on what type gets called
https://github.com/odin-lang/Odin/blob/master/core/math/linalg/general.odin
and for a more complex example
https://github.com/odin-lang/Odin/blob/master/core/sync/chan/chan.odin
You can also generate structs with variations at compile time and that should be enough for your use case, I think. Be careful though, it can bloat the LLVM IR and performance can take a hit. For generating struct types, you don't have to worry but if a proc does have lots of instruction, the optimization passes will find it hard to optimize the instruction. So keep the procs small when using parapoly if performance is your concern.

>Odin has "->" operator for exactly this purpose
All that does it modify the calling convention, there's no implicit first parameter or selecting the function based on the type

>>105926790

>>105926882
The calling convention does have an implicit first parameter which can be skipped as an argument.
You are not even reading and making everything seem pointless so that you can cry even more. Just get it over with lmao
>selecting the function based on the type
you didn't mention that as your "method" definition and you will need a vtable for that but you already said its not necessary so you need to get your shit together first. What a troll. Lets see what bs you'll come up with and how far you'll go.

>>105926926

>>105926988
>use godot
NTA but no thanks. It's pozzed (same as being zogged)

>>105926983
You're just proving how worthless you are. Who said it was basic programming questions I was asking? Oh right you did to discredit how worthless you were.

>>105927000
If AI can answer it, it's a basic programming question

>>105926999
Then use redot, personally I don't think using an MIT licensed engine is pozzed. You don't have to credit them, take their source code and change it, nobody can stop you. Hell rename the engine to "fuck godot". You're just upset some stupid tranny community manager on xitter said they were woke.

>>105927029
I wouldn't use godot's codebase at all, it sucks and their editor gui is crap

>>105927009
Thanks for the insightful help, I appreciate the heavy assumption and discrediting you do. Your work here is clearly valuable. Totally not proving my point.

>>105927040
I'm not trying to help you

>>105927037
Then use SDL3 and make your own shit or you can use Unreal 5 and have your game run like crap on nearly everything.

For me it's irrlicht

>no editor, so no unresponsive ui to worry about

>>105927059

its literally the same as zlib

>>105927055

Not using SDL3. I'm using SDL2+OpenGL3.

If AI can answer it, it's basic programming questions.
I've been doing a lot of SIMD programming, and I've noticed AI is completely useless in answering anything at all about it. It looks like it gives you something, but it's just gibberish every single time.
I wish I found some community or a friend who possesses the kind of advanced low level knowledge I am looking for.

>>105926989
AI is brilliant as a search engine, and that's how I exclusively use it myself. I don't make it ever do my work, unless I was going to slopcode anyway by copying some stackoverflow answer to quickly cobble together something I didn't really care about, something we've been doing anyway since the dawn of stackoverflow.

Actually now that I think about it, why not just edit irrlicht or some other FOSS game engine to make it into your own personal engine with your own additions, like how Source is based on the Quake Engine?

>>105927112
>If AI can answer it, it's basic programming questions.
Why do you ASSUME they're programming questions? This is all you know how to do, assume and discredit. That's what the majority of you people here do. Even if they WERE programming questions nobody said they were ANSWERED correctly by AI; they said they got a RESPONSE. I wish you could parse the English language a little better and stop being such a fucking midwit.

>>105927139
Irrlicht sucks ass and it would be better to make your own engine

>>105927141
>Why do you ASSUME they're programming questions?
Because we're in a programming thread talking about programming? What kind of retarded shit am I reading?

>>105927217
Yeah I'm seriously thinking about ditching this place and going somewhere else, the few progress posters left

>>105927141
The implication is that you find the answers of AI in some way helpful, if you keep asking it. May not be what you meant, but it's how it reads to us. Deal with it.
Also you might have the wrong expectations about these threads, no expertise is to be found here. It's very rare anyone genuinely competent in some extreme niche (eg SIMD programming) happens to lurk this thread when you throw your question in here, especially if you do it without some attention-catching image.

>>105927229

My bad Johnathon Blow. I didn't mean it.

>>105927289
Jon Blow isn't an artist

>>105927291
I disagree. I witnessed his art.

>>105927306
Maybe his online presence could be considered performance art

>>105927235
Okay answer me this, I had this to solve recently. Is there are an efficient reverse of _mm_movemask_ps()? Something that expands a 4-bit mask to SIMD regists with as few cycles as is possible.
You probably can't answer it because you're not an expert in this particular niche. AI can't answer this properly either.

>>105927320
That's hardly a game development question, if you were game developer I'd tell you to stop larping as a HPC guy because it doesn't matter

I never said they were GOOD.

>>105927397
I think if you were to take every game engine ever and sum up all the good games with it, Unity would come out on top by a mile

>>105927405
Well I don't want to make bad games.

>>105927408
At this rate, you're making NO games. :DD

>>105927408
An engine doesn't determine how good the game is

>>105927415
Never implied it did.
But it can possibly put a dent on the game's quality if the engine is crap (i.e the engine is named RPG maker or godot) or is misused (i.e the devs are lazy and just use default shit instead of being creative with the tools they're given).

>>105927347
This was part of a software occlusion culler, very relevant to game *engine* programming.

Btw the best solution I came up to it was this, quite simple actually but it wasn't instantly obvious to me.
i256 unmovemask() {
uint32_t arr[8];
for (uint32_t i = 0; i < LENGHT(arr); i++)
arr[i] = 1 << i;
return _mm256_load_si256((i256*)arr)
}

int main() {
const i256 comp = unmovemask();
uint32_t bits = 0b11001010;
i256 mask;
mask = _mm256_set1_epi32(bits);
mask = _mm256_and_si256(mask, comp);
mask = _mm256_compeq_epi32(mask, comp);
}

>>105927436
Godot's ok for 2D games
Unity is ok for most things an indie can put out

>>105927449
Do you really need a software occlusion culler with cutting edge performance?

>>105927454
Godot is just fine with 3D nowadays. It's not as good as Unity granted but it's not exactly super far off or anything.

>>105927464
>Godot is just fine with 3D nowadays
Disagree until I see people make non-shit 3D games with it

https://www.youtube.com/watch?v=J06tluN7rtE

>>105927477
There's this game
https://godotengine.org/showcase/planetenverteidigungskanonenkommandant/
It's not out yet, though and might be terrible so I guess yeah there's really not any proof yet. I do think it's capable, though the only people who use godot seem more interested in making 3D PSX slop or 2d games.

>>105927509
A game engine is only capable until it's battle tested, and a one-room game is a very small battle

>>105927462
I do, I don't want to make 20fps unity slop. And the better my engine performs the better I can realize my dreams.
But my drive to do stuff like this is more about becoming a better programmer and just genuine interest at this art of low level performance programming. I've never really been money motivated.
I honestly find it very odd that just cool programming isn't respected here anymore.

>>105927507
>every font is free if you're willing to recreate it
Yeah I mean, I suppose
>>105927533
>A game engine is only capable until it's battle tested
I slightly disagree, a game engine is only proven capable after being battle tested. I still think it's very capable I just can't really prove that to you, yet. I give it a couple more years and I think you'll change your mind.

>>105927547
Who says people don't respect cool programming?
I respect people who can scope their projects more though as you probably don't need to use advanced SIMD to squeeze out all possible performance, you're just getting stuck in a mental rabbit hole

>>105927551
As soon as anything speculative is put into production people will find a million bugs and performance issues that need to be worked over

>>105927320

You don't know what I am doing or by what I am motivated by.
This particular project isn't ever going to become a game, it's a proof of concept software renderer.

>>105927591
Those don't exist for SIMD registers afaik.
To visualize, the problem was to expand
0b1011
into
ffffffff, 00000000, ffffffff, ffffffff
without a scalar loop with ternaries like usual.

AVX512 seems to actually have _mm_mask_set1_epi32 which does this, though it's still 3 cycle latency (same as mine) and .. well it requires AVX512. So it's a no-go.

>>105927674
>This particular project isn't ever going to become a game, it's a proof of concept software renderer.
That's why I prefaced this discussion with "if you're a game developer"

>>105927683
Eventually I will use this technology in a game. I wouldn't be working on it otherwise.

>>105927698
You just said it wasn't going to become a game

>>105927701
>This particular project
This exact project folder? No. But the technology and techniques will.

>>105927705
In that case you're totally wasting your time working on a software renderer

>>105927674
you can just unroll the loop a bit. the compiler should do that for you

>>105927709
Man this is exactly the kind of argument I get into every time I join this thread. This hustle culture is fucking cancer. To go /biz/ or something, this is supposed to be /g/, A TECHNOLOGY BOARD.

>>105927752
Masturbatory programming that doesn't achieve any results or solve any problems is even more meaningless than the hustle culture that puts results over everything else

>>105926988
Godot kinda sucks, no one has made a non-crap game in it.

Hey guys I'm working on a multi platform UI toolkit. It could possibly be implemented in a game in the next decade, possibly maybe. The game and game engine development thread is the right place to post, right? I use rust, btw.

>>105927773
I liked Cruelty Squad and Buckshot Roulette. You'll say they're bad but you're wrong.

>>105927750
I mean, my solution >>105927449 basically does that, where I've unrolled the loop directly to SIMD registers. It just needs a constant "unmovemask" to do the cmpeq against.

>>105927764
>occlusion culling doesn't solve a problem
alright
You are why I wont post in this general ever again.

>>105927826
Maybe you're solving a problem, it's just not a real one

>>105927826
im not sure i understand, why wouldnt pdep followed by a set1 of uint_max get you the mask you want?

>>105927882
set1 broadcasts 1 scalar value to all lanes of the simd register

>>105926934
I don't know how to expect the compiler to achieve that without using vtables. Using something like generics can be a valid workaround without relying on vtables but if not, you do need them.
Instead of bland suggestions on how a language can implement a feature, refer to an already well implement examples and cite them, if you can claim your statements to be true to any extent.

>>105919609
get a real engine first.
do you think all memedot games are pixel art or retro ps1 style because the devs want?

>>105927922
>do you think all memedot games are pixel art or retro ps1 style because the devs want?
Literally, yes. Unity has just as much PS1 style slop. I don't know if you've noticed this but that's been a pretty big trend right now in the indie world.

>>105927674
>0b1011
>into
>ffffffff, 00000000, ffffffff, ffffffff
...can that just be a multiplication? ...Probably not. Feels to me like there should be a trick-of-that-nature. Like maybe https://graphics.stanford.edu/~seander/bithacks.html#InterleaveTableObvious . Basically you're interveaving with itself n times, yeah? It doesn't use SIMD but maybe you can adapt something.
Also maybe check what the compiler generates, maybe it already knows the answer.

>>105927895
Wait can't you just broadcast with a mask? Sorry I don't know simd particularly and am not going to do code/reading comprehension.

>>105927752
ARGH! IT'S THE SOFTWARE RASTERIZATION TARD EVASIVE MANEUVERS, EVASIVE MANEUVERS!

>>105927782
Welcome. Perhaps a screenshot?

>>105927972
>...can that just be a multiplication? ...Probably not.
The standard scalar loop solution basically is, you just loop the bits and ternary/multiply with UINT32_MAX if the bit is set.
But you need to do that 4-8 times, with a handful cycles for each loop. I was looking for a solution that did all this in couple cycles at most. My solution does achieve that, if we don't count the one-time set up of the "comp" mask.
>Wait can't you just broadcast with a mask
That's an AVX512 feature, and AVX512 obviously isn't something I can target.

>>105928061
what about this implementation, but just using avx2?
https://richardlupton.com/posts/invert-movemask/

>>105927909
vtables are only required for dynamic dispatch, if there's no dynamic dispatch you can determine the method that needs to be called based on the type at compile time
ultimately it's his choice how he makes his programming language but if just plain structs and functions were enough for anyone why bother switching off C in the first place

>>105927953
godotranies started that because their patreon-scam engine can't handle good looking graphics.
unity and unreal can have more too, but they also have millions of games with good graphics, while bugdot don't have a single game with good stylized art.

>>105918733
That guy is cool and motivates but I then imagine about the gap between drawing a rectangle in Raylib and building Terraria and then I give up

>>105928144
Building a Terraria-like game is actually pretty easy

>>105928074
His solution is fundamentally the same as mine, using "and" with "cmpeq" to generate the final result, but his is more complicated (and slower) because it needs to do some shuffling to work with 8-bit lanes, while I was only concerned with 32-bit ones.
But that's cool that you found someone doing the same thing I did, sort of.

>>105928101
literally a skill issue. the engine can handle good graphics just fine. you unitytards are the biggest faggots of them all. By the way, Sonic Colors used godot.

>>105928207
then use the 32 wide equivalent of his?

then you'll need to rely on something like generics if you do not wish to rely on vtable for getting the job done, which again is usually requires an additional line of work. Stop ignoring your own words and get your shit together lmao
>why bother switching off C in the first place

I did not seriously try it yet but I liked their shader language.
From my experience, apart from WGSL shader language being convenient, resembling hlsl for the web and saner than glsl, I don't have much to share.

stop overthinking game architecture. just use virtual void update(); etc to update game objects.

Thoughts on wgpu? I have seen some engines use it. Is it really that good?

transform matrices are arcane magic

look up generic_select or whatever it is.

matrices are more intuitive if you write matrix operations like this

struct mat4 {
//xyz axes, store rotation and scale (as vector magnitude)
vec4 x;
vec4 y;
vec4 z;
//translation vector
vec4 w;
}
vec4 TransformVector(mat4 matrix, vec4 vector) {
return vec4(matrix.x * vector.x + matrix.y * vector.y + matrix.z * vector.z + matrix.w * vector.w);
}

mat4 TansformMatrix(mat4 parent, mat4 child) {
mat4 result;
result.x = TransformVector(parent, child.x);
result.y = TransformVector(parent, child.y);
result.z = TransformVector(parent, child.z);
result.w = TransformVector(parent, child.w);
return result;
}

so I've gotta go through them all to find the most recent version of each file, kill me

I'm going to fucking kill myself if I have to dumpster dive through all the node_modules files mixed into one.

I've managed to sort them for the most part, different file types were automatically detected at recovery and I've been using key string searches for things I know I wrote into it
still a shitload of files to dig through
