The prompt
Using Three.js, create a polished, fully playable 3D dark-fantasy action RPG from scratch.
Use a top-down angled follow camera. The setting is a grand Gothic sanctuary reclaimed by forest, featuring ruined towers, arcades, moss-covered stone bridges, rolling hills, streams, waterfalls, and campfires. Create a richly layered atmosphere through realistic materials, cinematic lighting, light mist, wind-swept vegetation, and flowing water.
The protagonist is a powerful knight wearing intricately crafted steel-and-gold heavy armor, with a flowing cape and a glowing rune sword and shield. The character must be able to move, slash, roll, block, heal, and cast magic featuring massive magic circles, beams of light, and lightning effects. After defeating the guards, the player must face a giant antlered knight boss.
Attack animations, visual effects, and hit directions must all match the character’s facing direction. Include a polished Traditional Chinese HUD, a character equipment display, and complete victory, defeat, and restart flows.
Handle the modeling, asset creation or acquisition, programming, and performance optimization independently. Aim for AAA-level visual polish. Continuously playtest the game, inspect the visuals, and fix issues until delivering a complete playable game, launch instructions, and the source code.
