Please use Three.js to generate a **mobile-first game** with the theme "**Hill Racing**". Please read the following detailed game design requirements first, and then generate the code accordingly. The game must use a 2.5D perspective (3D objects, side-scrolling view) and integrate a physics library (like Cannon.js) to handle vehicle dynamics. ### 1. Assets & Environment * **Visual Style**: 2.5D Cartoon aesthetics with high saturation. Use a fixed Orthographic camera or a distant Perspective camera to simulate a flat side-scrolling look while maintaining 3D depth. * **Terrain**: Procedurally generated hilly terrain using perlin noise. The top surface should be bright green (grass) and the side cross-section should be textured brown (dirt/rocks). * **Vehicle Models**: Create a "Monster Truck" style chassis. It should have a main body (vibrant red or purple), large black knobby tires, and visible suspension springs. The driver should be a simple low-poly human figure. * **Background**: Implement a parallax scrolling background with multiple layers: * *Layer 1 (Closest)*: Silhouette of trees/bushes (dark green). * *Layer 2 (Mid)*: Faded forest shapes (yellow-green). * *Layer 3 (Far)*: Simple gradient skybox (yellow to blue). * **Collectibles**: * **Coins/Stars**: Gold, rotating meshes. * **Fuel**: Red jerry cans with a subtle glowing effect. * **Performance**: Use simple geometries (BoxGeometry, CylinderGeometry) for the car parts to keep draw calls low. Use object pooling for terrain segments and collectibles to ensure smooth 60fps on mobile devices. ### 2. Audio Requirements * **BGM**: An upbeat, looping "Country/Bluegrass" style track using banjo and drums to match the off-road theme. It should be energetic but not distracting. * **Sound Effects (SFX)**: * **Engine**: A looping engine rumble that modifies its `playbackRate` based on the car's current speed/RPM. * **Suspension**: A "squeak" sound when the car lands hard. * **Collectibles**: A high-pitched "Ding" for stars; a liquid "Gulp" sound for fuel. * **Game Over**: A "Crunch" sound for crashing; a "Sputtering" engine sound for running out of gas. ### 3. Gameplay Loop * **Physics Core**: The car is the primary focus. It must use rigid body physics (chassis connected to two wheels via spring/damper constraints). * *Balance*: The player must balance the car in the air. Accelerating tilts the nose up (wheelie), braking tilts the nose down. * **Objective**: Drive as far as possible without flipping over or running out of fuel. * **Fuel System**: A fuel timer constantly decreases. Collecting a Fuel Can resets or adds to the timer. If it hits zero, the car slowly halts -> Game Over. * **Fail State**: If the car's roof (or driver's head) touches the ground -> Immediate Game Over (Crash). * **Scoring**: Score is calculated by `Distance Traveled + (Stars Collected * 10)`. ### 4. Mobile Controls & Interaction * **Screen Orientation**: Forced **Landscape Mode** for the best field of view. * **Touch Controls**: * **Right Pedal (Gas)**: A large button (min 88px area) on the bottom-right screen. Holding it applies torque to wheels. * **Left Pedal (Brake/Reverse)**: A large button on the bottom-left screen. Holding it applies reverse torque/braking. * **UI Layout**: * **Top Center**: Distance counter and Star count. * **Top Left**: Fuel Bar (visual gauge changing from Green to Red). * **Center Overlay**: "Tap to Start" or "Game Over / Restart" buttons. * **Feedback**: * **Camera**: The camera must smoothly follow the car's X-position but have a slight "lag" on the Y-axis to smooth out bumpy terrain. * **Visual**: Dust particle effects emitting from the tires when touching the ground. * **Haptic**: Trigger a short vibration (`navigator.vibrate(50)`) when collecting items or landing a big jump. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
