Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Roller Coaster Builder 2". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Adopt a **clean, vibrant low-poly aesthetic** that mimics the bright contrast of the reference image. The skybox should be a clear, deep azure blue (CSS `DeepSkyBlue` or similar). * **The Coaster**: The primary asset is the track generator. The track itself should be **bright red** with a tubular design, and the structural supports (pillars) must be **white** with lattice-work textures or geometry. * **Track Generation**: Use `THREE.CatmullRomCurve3` to generate smooth tube geometries dynamically based on user input points. The supports should automatically extend from the track down to the ground plane (y=0). * **Environment**: A flat, grassy green grid based ground (infinite plane) to serve as the construction canvas. Floating "Star" or "Coin" tokens should be placed in the sky as objectives for the coaster to hit. * **Mobile Optimization**: Use `InstancedMesh` for repeated track ties/sleepers and supports to maintain high FPS on mobile devices. Limit shadows to the coaster cart only. ### 2. Audio Requirements * **BGM**: An upbeat, creative "simulation/tycoon" style track—light acoustic guitar or synth-pop that implies productivity and fun. * **SFX - Construction**: * *Placement*: A satisfying metallic "Clank" or "Snap" sound when a track segment is placed. * *Delete*: A "Whoosh" or crumple sound. * **SFX - Simulation**: * *Chain Lift*: The iconic "Clack-clack-clack" mechanical sound when the cart is going up steep hills. * *Coaster Roar*: A looping wind/rumble noise that changes pitch based on the cart's velocity. * *Success/Fail*: A cheerful chime for reaching the goal; a comical "crash" sound if the cart flies off. ### 3. Gameplay Loop * **Phase 1: Construction (The "BUILD" Mode)**: The player is presented with a Start Point and an End Point in 3D space. Between them are floating obstacles and collectible coins. The player must draw/place track nodes to connect the start to the finish. * **Phase 2: Simulation (The "RIDE" Mode)**: The player presses "Play." A physics-based cart spawns at the start. * **Physics Logic**: The cart must obey conservation of energy (momentum). If a hill is too high relative to the previous drop, the cart rolls back (Fail). If a turn is too sharp at high speed, the cart derails (Fail). * **Win Condition**: The cart successfully travels the entire track, collects at least one star/coin, and stops safely at the finish zone. ### 4. Mobile Controls & Interaction * **Screen Orientation**: **Landscape Mode** is preferred for a wider construction view. * **Camera Controls**: * *Two-finger pinch*: Zoom in/out. * *Two-finger pan*: Move the camera across the build plane. * **Building Controls (Touch)**: * implement a **"Draw Mode" toggle**. When active, dragging one finger on the screen draws the 3D curve (projected onto a depth plane). * Alternatively, provide **"Add Node" buttons** (Up, Down, Left, Right) for precise piece-by-piece construction if free-drawing is too complex for the touch interface. * **UI Layout**: * Action buttons (Play, Reset, Delete, Undo) must be at least **48x48px** and anchored to the right thumb zone. * A prominent "Test Run" button in Green. * **Feedback**: Trigger **Haptic Feedback (Vibration)** when a track piece snaps to the grid or when the coaster collects a coin during the simulation. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
