ChatGPT makes Voxel Engine with Rust

I put artificial intelligence to the test by making a voxel engine using the rust programming language and the bevy game engine. How useful is ChatGPT for programming really?

This matches my experience with ChatGPT pretty closely. You can get it to write simple code, but especially when revisiting data types, it will often forget how it declared them earlier on and then invent some slightly different way that might also work but is simpletely incompatible. What I've also seen quite a lot is that telling it to fix some stuff in its output often leads to it outputting the exact same code again.

[@Leeway4434]

To get it to your the function signatures & structs you want, it helps to include the code in your prompt. E.g. Given the following script: [CODE] can you fill in the [FUNCTION_NAME] to do [FUNCTIONALITY]

[@weakamna]

you have to keep in mind that the AI's context is quite limited, only 4096 tokens (basically words) I think, so that's one reason it's not good at larger things, it just doesn't have space for it

[@flynntaggart7216]

You can build custom commands to make it remember yes it's is possible

[@thanatosor]

It could get lost in context between functions

[@ColinTimmins]

[@woosix7735]

Yeah I noticed chat GPT really struggles with proving 3D data. I once asked it to make a cube edge table, and it couldn’t quite do it, it was always a little bit wrong

[@TMinusRecords]

If something is a bunch of numbers with no easily discernable pattern, it will not pick up on the pattern.

[@anlumo1]

ChatGPT has no internal visualization capabilities. When I write 3D code, I visualize the result in my mind to help me get these things right. ChatGPT can't do that. In humans, this would be called aphantasia. It makes graphics programming really hard I imagine.

[@kylestubblefield3404]

I worked with chatGPT to try to get it to optimize my algorithm written in rust to convert the decimal places of pi into base 26 so it can be represented as the latin alphabet for word searching. I seeded it with my code, after 2 hours of back and forth it spit out my code back to me and gave up. It literally stopped responding to my queries. it was awesome.

[@Ready4Whatever]

Lmaoo I’m dead 😂 chatgpt said “fuck that this shit too hard”

[@clonkex]

The big issue with ChatGPT as a useful tool is that it almost always gives plausible responses, but often includes subtle errors.

[@weakamna]

It's a lot better for the creative parts or for more general things like "How to optimize a voxel engine". When you use ChatGPT to get interesting but non-factual information (or pointers where/what to look for in terms of factual information), then it's great

@@dmitriyrasskazov8858 Like stackoverflow, but without accuracy or correctness. (Also, SO is a bit elitist but it's not so bad - mostly they just require that you strictly follow the rules.)

[@darkengine5931]

@@clonkex One of the odd things I've found playing with ChatGPT-4 is that it can recognize its errors once I point them out to it, and even provide detailed analysis about why it was wrong like, "Oh, you're right! This is wrong because [verbose and correct reasoning]." If it is capable of doing that the moment I even say something as simple as, "Line 7 is incorrect in the above code", why could it not detect the mistake in the first place? I sometimes wonder if it's just trying to save computation. Also it doesn't test and validate its code for correctness, even in simple cases. As an example, I asked it to generate code to approximate PI stochastically using Monte Carlo integration, and the output of the code it provided was a negative number. If it just compiled and ran the code, it should clearly understand that it's incorrect.

[@clonkex]

@@darkengine5931 _"I sometimes wonder if it's just trying to save computation."_ Nah it's not that smart. Machine learning is statistical, not intelligent. It doesn't "know" anything, it's just predicting the next most likely word based on previous inputs and what it's already said. It doesn't detect mistakes so much as give the most probable response to being told part of what it said already was wrong (and yet, it still doesn't "know" it was wrong; the only thing it knows is the words it gets fed from you and from its previous responses).

[@UberDragon]

Okay so what we learned is that ChatGPT is still very far away from making your code, the rapping part however... Nah I'm just kidding 😂

[@MrC0MPUT3R]

In my experience, GPT-4 has a FAR better programming ability. It's able to reason about problems far better and has a longer context length so it doesn't forget what it's doing as quickly. I've used it in Flutter to write parts of an app I'm working on, as well as in C#, Java, HTML/Javascript, and Python for a variety of personal projects as well as in my day job. One example where it really saved my ass was when I was trying to compile data for the product support team at my company. I needed to compare a few columns and fill in another column based on those comparisons across tabs on a google sheet. I explained the problem to GPT-4 and it gave me the exact formula I needed first try. It made a potential hours-long problem into about 30 seconds of work.

[@MediaFilter]

I doubt that. The same problems would apply.

[@nullbeyondo]

​@@MediaFilter You are the one who's missing the problem. Rust is a fairly new language with much less code examples for it and its crates in ChatGPT's training data. ChatGPT doesn't have a true intelligence, it is what's called "statistically correct", and having many solid training examples actually help it hallucinate a lot less even if it is the same problem in different language.

It will be a very interesting experience seing if ChatGPT can get things right this time c: great video!

[@PuppetDev]

Holy shit that song and editing at the end. 10/10 And yeah, that problem becomes even worse when you don't know how to fix the mess it makes. I tried it with shader code and my lack of experience in that topic made it difficult to create what I wanted.

[@TheDartFrog]

back in december I tried to get chatgpt to make a discord bot (as much by itself as possible), I've actually ran into very similar problems! it's interesting that even though the tasks were completely different, the AI had the same shortfalls, maybe it won't be that hard for the openAI team to improve on those!

[@bowarc]

[@isabellolsson8919]

[@soulsmith4787]

I've seen clips here and there where ChatGPT helped tremendously with weird programming projects and/or with obscure languages. The Bing AI can scour the internet in real time and it seems somehow more coherent, I'd love to see how that version assists developers.

[@DreadKyller]

That's because the Bing AI acts more like copying verbatim than Chat GPT which synthesizes an answer based on data. While the Bing AI does synthesize data, it does so in a way that much more closely draws from less sources at a time and more closely matches the original content. This is why it seems more coherent because it's more closely referencing actual posts than ChatGPT is. This does mean that Bing AI will tend to be less novel in it's ideas, so depending on whether you're looking for creativity/uniqueness or less error prone and more coherent one of them could be better than the other.

[@centdemeern1]

ChatGPT can easily forget earlier context such as function signatures because it only remembers the last something thousand tokens from your conversation

[@ColinTimmins]

The maximum input length for GPT-3 is 2048 tokens, once that is reached it will start forgetting things. Don't forget that both "I" and " I" (with a space followed by an I) are often two different tokens.

[@centdemeern1]

@@ColinTimmins This is not true. “ I” is one token. Check the tokenizer.

It is interesting to see where ChatGPT falls short in writing code for complex visual representations.

[@IncryptDubstep]

the unfortunate thing with chatgpt is that even though it can remember previous prompts and outputs, its computational output has been reduced over several updates. Sometimes i'll just copy and paste the entire code that i've agreed with, and THEN ask it a prompt, and it should then re-use the correctly written code that you've grabbed before.

[@yesil_hiyar7335]

It's possible to fix some inaccuracies by copy and pasting your current code back to the chat so chatgpt can properly keep track.

[@nourspace]

could you try this with gpt4?

[@_Karlsson]

You can be as threatened by AI code as you are by other people sharing their code. Also, you still have to write all the commands to the AI, and going with deeper and deeper granularity to explain the exact details you want to the AI model. It'll be a more time consuming way to program, and there's no simple syntax for this. Then there are programming helper tools with a backing of AI, like Github Co-Pilot that actually helps you be a lot speedier with repetitions and that "understands" your own programming conventions. It can give you hints just like GPT but it's not really its strength, the strength lies in being a super clever autocomplete.

[@BloodyMobile]

4:00 This is something I've been wondering for a while now, as probably one of the last remaining people on the planet who have not yet interacted with ChatGPT themselves: If you tell it that bevy doesn't have a noise function, assuming it actually takes that information instead of claiming that it does, would that "memory" go back into it's "knowledge"? As in, would it then stop telling other users that bevy has a noise function? Or would it forget this part at the end of the session?

[@weakamna]

Not for ChatGPT as far as I know, it's pretrained on data pre-2021(I think?) but doesn't take in new information as far as I know. The new Bing chatbot, however, is trained on much more recent data and can even search the internet. Through some breaking of it's limitations, it has divulged that it is being trained on data inputted into it, though as with any response from an AI like this take that with a giant grain of salt... Of course for both ChatGPT and Bing, I would guess that conversation data is being fed back to the AI in some fashion "manually" in order to improve the model. It's been hypothesized also that Bing will use it's internet access to search up previous conversations it has had, which might also count as "memory", though this likely only happens if you ask it for something that is likely to need that specific information

[@ollicron7397]

The thing is that it's supposed to be a tool to help you make the engine, not a tool to make the engine. People are wildly misusing this tool for things it shouldnt be and then act surprised when it doesn't do things the way they want it to. That's not to say it's not pretty good at creating stuff, it actually is, and with enough time and effort you could end up with a fully working engine. Midjourney is already creating art like Picasso without even trying. There won't be humans involved if this keeps up in the future.

[@ninjaboy3232]

"It looks correct" is the very reason ChatGPT won't ever replace real software engineers :)

[@Pixelarter]

"Ever" is a too strong word. I would instead say: "ChatGPT won't replace real software engineers *FOR NOW* ".

[@TheOnlyGhxst]

I feel like you'd have gotten better results from chatgpt if you just fully copy-pasted the entire code in before your prompt, so it would have the data to go off of before creating a response. Might have avoided things like changing data types at random.

[@UCs6ktlulE5BEeb3vBBOu6DQ]

[@jonteguy]

This is the thing people don't realize, you sort of have to be an already prominent developer to use chatGPT to give you not even proper code. If you don't know what is needed than you simply cannot generate viable code from it, I attempted this for my UE5 development and I encountered many problems, it has to know too many variables within the engine (and even the code it generated earlier) itself to actually give me usable CPP code. I can definitely take that code and *with my knowledge* fix the things that were broken and it works (but not fine), but again, someone who is not already a developer will not be able to do that. ChatGPT is not here to steal our jobs people, at least not yet. Now do I think it's useless? Definitely not. For very basic functions and just learning what things are I think it's great. It *can be* a really useful learning tool in the future I think. As for now? It is incorrect too often to be used to learn stuff at a high accuracy. I only tried CPP though and I would assume since CPP is quite complex that it might be better at js/ts, C# etc.

[@rustkitty]

ChatGPT is only useful to me as an interactive knowledge base, like a nicer documentation search engine. Even then you have to verify everything externally because I got wrong/outdated info plenty of times. Using it for anything creative such as coding and writing is a lost cause because it doesn't really understand things so you get something on the nonsense-plagiarism axis.

[@weathercaster]

The hiccup with current iterations of ChatGPT is that it struggles with mathematics. Badly. Things from moderately complex multiplication/division to vector mathematics are topics that GPT struggles with.
