I'd like to add to what the other commenter said. I use the same stack but I mostly limit Copilot to autocomplete, the built in chat is not really as good as just copying and pasting into GPT-4 for anything even remotely complex. There is also Cursor https://www.cursor.so/ which integrates GPT-4 into the IDE but you do have to switch to using their custom version of VSCode. ChatGPT Plus is also getting multi-modal support so you can send it images, this has been useful for working on webdev for me but I could see it being useful in gamedev as well. If you haven't used ChatGPT much before, make sure to fill in your Custom Instructions with details about yourself and your preferred communication and programming styles. It really helps focus the model on your use case.
