Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Friday Night Funkin' (Rhythm Battle)". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: 2.5D "Paper Diorama" aesthetic. Use flat 2D textured planes (meshes with transparent PNG textures) positioned in a 3D space to mimic the original vector art style. * **Character Setup**: * **Player (Boyfriend)**: Positioned on the right foreground. Blue hair, red cap, holding a microphone. * **Opponent (Daddy Dearest)**: Positioned on the left foreground. Purple skin, menacing suit. * **Background Character (Girlfriend)**: Sitting on large boombox speakers in the center-back. * **Environment**: A dark, urban stage setting. Use a dark purple brick wall texture for the background plane. Implement dynamic lighting: `SpotLights` that pulse in sync with the beat, illuminating the active singer. * **Mobile Optimization**: Use a texture atlas for all character sprites to reduce draw calls. Limit dynamic lights to 2 max. Use `MeshBasicMaterial` for background elements to save performance. ### 2. Audio Requirements * **BGM**: A high-energy, looping "Nu-Jazz" or "Electro-Funk" instrumental track (100-120 BPM). * **Vocals**: Instead of full lyrics, implement distinct "Beep/Boop" synthesized tones. High-pitch sine waves for the Player, low-pitch saw waves for the Opponent. These should play when notes are hit. * **SFX**: * **Hit**: A satisfying snare or clap sound. * **Miss**: A jarring "record scratch" or discord sound. * **Combo**: A rising pitch chime for every 10 consecutive hits. ### 3. Gameplay Loop * **Core Mechanic**: A 4-lane rhythm system (Left, Down, Up, Right). "Arrow Notes" scroll upwards from the bottom of the screen toward a static "Receptor Bar" at the top. * **Turn-Based Battle**: The camera should slightly pan/zoom towards the character currently "singing" (whoever has the active note stream). * **Scoring System**: * **Perfect/Sick**: Hitting the note within 50ms (Green splash effect). * **Good**: Hitting within 100ms. * **Miss**: No input or wrong timing (Character sprite flashes red briefly). * **Health Bar**: A "Tug-of-War" style bar at the bottom. The bar starts 50/50. Successful hits push the green bar (Player) to the left; misses allow the red bar (Opponent) to push right. If the bar becomes fully red, Game Over. ### 4. Mobile Controls & Interaction * **Touch Interface**: Create a transparent overlay at the bottom 25% of the screen divided into 4 distinct touch zones (Left, Down, Up, Right). * **Visual Feedback**: When a zone is touched, the corresponding arrow in the Receptor Bar must glow or scale up instantly (0 latency visual response). * **Orientation**: Force **Landscape Mode** for wider note separation. * **Haptics**: Trigger `navigator.vibrate(50)` on a "Miss" and a lighter `navigator.vibrate(10)` on a "Perfect" hit. * **UI Layout**: * Score text in the bottom left corner. * Health bar centered at the very bottom (away from touch zones). * Pause button in top-right corner (min size 44px). Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Gameplay Mechanics

Core Rhythm System

The gameplay revolves around hitting arrow keys (or WASD) when colored arrows align with stationary markers on screen.
