I'm afraid I'm only doing 2d ... Yes, GUI related LLM instructions have been exceptionally bad, with multiple prompts me saying "no there is no such thing"... But as I commented earlier, GPT has had it's moments.

I strongly recommend giving Gemini 2.5 Pro a shot. Personally I don't like their bloated UI, but you can set the temperature value, which is especially helpful when you are more certain what and how you want, then just lower that value. If you want to get some wilder ideas, turn it up. Also highly recommend reading the thought process it does! That was actually key in having very complex ideas working. Just spotting couple of lines there, that seem too vague or even just a little bit inaccurate ... then pasting them back, with your own comments, have helped me a ton.

Is there a specific part in which you struggle? And FWIW, I've been on a heavy learning spree for 2 weeks. I feel like I'm starting to see glimbses from the barrel's bottom ... it's not so deep, you just gotta hang in there and bombard different LLMs with different questions, different angles, stripping away most and trying the simplest variation, for both prompt and godot. Or sometimes by asking more general advice "what is current godot best practice in doing x".

And YouTube has also been helpful source, by listening how more experienced users make their stuff. You can mostly skim through the videos with doublespeed and just focus on how they are doing the basics. Best of luck!
