A developer prototypes game UI in HTML with assets and logic finalized, then uses AI to implement it in Unity in about two hours.
Adapted from @Stefan_3D_AIDay 9. Building the game I've dreamed of for 15 years with AI. I'm still in shock from GPT-6. Today I handed it my game's UI. I'd started working on it last week with Fable 5.1 and design skills. I built it in HTML first, preparing the images and icons along the way. Figuring out what I wanted and how it should work took time. I needed that time. I also made animated character portraits. I tried Seedance 2.5 for those, and MiniMax H3 gave me much better results for this job. By the end, I had an interactive prototype with the UI logic worked out and all the assets ready. I could click through it and test how everything behaved before taking it into the game. Once I'd tested it and worked through the remaining questions, I opened GPT-6 in the same project. Gave it the interface and all the materials, and asked it to implement everything in Unity. About two hours later, I had a working UI and nothing to complain about. GPT-6 even went through different resolutions on its own. I'd expected this part to be difficult. It ended up being one of the easiest parts so far. I'd recommend building your UI in HTML first. Iterations are faster, you can click through it just like a real interface, and it's easier to catch the things you missed. Once you've worked those out, connect it to the game. You still have to wait for the engine to compile, whether you write the code yourself or use AI.
