Stop ChatGPT From Making Up Code
Ugh, I totally feel your pain. There’s nothing more annoying than getting a "perfect" script only to realize half the methods are pure fiction. I’ve spent way too much time debugging "ghost functions" in Pygame myself. It happens because these models are basically "super-complete" machines; they prioritize sounding helpful and fluent over being 100% accurate when they're unsure of a specific library version.
I've found a few practical ways to "handcuff" the AI to reality so it doesn't wander off into hallucination land. Here is what has been working for me lately:
- Provide the "Source of Truth": Instead of just saying "use official docs," copy and paste the specific section of the documentation you're working with directly into the chat. Tell it: "Base your code strictly on this documentation snippet." It’s much harder for the AI to hallucinate when the correct answer is staring it in the face.
- The "Verification Step" Prompt: I started adding a specific instruction at the end of my prompts: "Before providing the code, list every library-specific function you intend to use and verify it exists in the current version of Pygame." This forces the model to double-check its "memory" before it starts typing the actual script.
- Specify the Version: Be incredibly specific. Don't just say "Pygame." Say "Write this using Pygame 2.x syntax." This helps prevent it from mixing up old, deprecated methods with new ones, or worse, inventing a hybrid that doesn't exist.
- Ask for Small Modules: When you ask for a full game script, the model’s "attention" gets stretched thin, and that’s when the hallucinations start. Try asking for just the player movement, then just the collision logic. Keeping the scope small keeps the code accurate.
Try a "Strict Mode" Persona
Sometimes, giving the AI a very specific "persona" helps. Try starting your prompt with something like this:
"You are a senior Python developer who hates debugging non-existent library functions. You never use a function unless you are 100% certain it is in the official Pygame API. If you aren't sure, use a custom helper function instead of guessing a library method."
It sounds a bit silly, but setting that boundary really helps. Also, if you're using GPT-4 with web browsing, explicitly tell it to "search the latest Pygame documentation on the web to verify function names" before it generates the response. That usually kills off the hallucinations entirely.
Good luck with the game! Hopefully, this saves you from at least a few "AttributeError: module 'pygame' has no attribute 'made_up_function'" headaches.
