Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Offroad Island**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Stylized "Sim-Cade" realism. Use PBR (Physically Based Rendering) materials but keep geometry optimized for mobile devices (Low to Mid-poly). * **Main Asset (Player)**: A rugged, red 4x4 off-road jeep (similar to a modified Wrangler) with oversized knobby tires, a roll cage, and roof lights. The model must have separate meshes for the chassis and the four wheels to allow for physics-based suspension animation. * **Environment (The Island)**: A large-scale terrain generated using a heightmap to create uneven ground, steep hills, and mud pits. * **Textures**: Blend textures for grass, mud (dark brown, high roughness), and rock. * **Scatter Objects**: Low-poly pine trees, rocks, and wooden ramps/obstacles for stunts. Use InstancedMesh for vegetation to maintain 60 FPS on mobile. * **Lighting**: A sunny daylight setup with a DirectionalLight (casting shadows on the vehicle) and an AmbientLight. Add a subtle fog effect to mask the draw distance boundaries. * **Particles**: Dirt/dust trails emitted from rear wheels when accelerating; mud splash particles when driving on brown terrain areas. ### 2. Audio Requirements * **BGM (Background Music)**: High-energy instrumental Hard Rock or Southern Rock (guitar riffs and drums) to match the aggressive driving style. * **Sound Effects (SFX)**: * **Engine**: Dynamic engine pitch that rises with speed/RPM. * **Tires**: Crunching sounds for gravel, squishing sounds for mud. * **Suspension**: Metallic squeaks when landing jumps. * **UI**: Mechanical "click" sounds for button presses; a satisfying "cha-ching" sound when collecting coins. ### 3. Gameplay Loop * **Core Mechanic**: Physics-based off-road driving. The player must navigate difficult terrain without flipping the vehicle. * **Vehicle Physics**: Utilize a physics engine (like Cannon.js or Ammo.js). Implement a `RaycastVehicle` to simulate suspension travel, friction, and 4-wheel drive power. The car should feel heavy and bouncy, not floaty. * **Objectives**: 1. **Exploration**: Roam freely across the map. 2. **Collection**: Gold coins are placed in difficult-to-reach spots (top of steep hills, mid-air on ramps). * **Progression**: Display a "Score/Money" counter UI that increases when coins are collected or air-time (stunts) is achieved. * **Fail State**: If the car flips upside down, provide a "Respawn/Flip" button. ### 4. Mobile Controls & Interaction * **Screen Orientation**: Landscape mode locked. * **Touch Controls (Multi-touch enabled)**: * **Steering (Left Hand)**: A Virtual Joystick or Left/Right Arrow buttons placed in the bottom-left corner. * **Throttle/Brake (Right Hand)**: Distinct vertical pedals. Right pedal for Gas, Left pedal for Brake/Reverse. * **Action Buttons**: * **Camera Toggle**: A button (top-right) to switch between Third-Person (Chase Cam) and First-Person (Hood Cam). * **Respawn**: A "Reset Car" icon (top-left) to upright the vehicle if flipped. * **4WD Toggle**: A toggle button to switch between 2WD (rear) and 4WD for climbing steep hills. * **Feedback**: * **Haptic**: Trigger device vibration (if supported) when crashing or landing hard jumps. * **Visual**: The UI buttons should scale down slightly or change opacity when pressed to indicate active touch. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
