anselm · x · 2026-07-20
This shares a demo of a custom game engine, "古矢沢エンジン": the developer used AI tools like Codex and GPT-5.6 Sol to help build it. Under the setting of "360 seconds = 1 in-game day," they increased the running speed by 20x and recorded a video spanning about 3 day-night cycles.\n\nThe video highlights:\n- Time-varying background effects\n- A continuously scrolling event log in the bottom left corner\n\nThis is an engineering-focused showcase of AI-assisted game development.
