Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Derby Crash 4 Mobile: Sandbox Destruction". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Semi-realistic 3D open-world sandbox. Use low-poly meshes with high-quality baked textures to simulate realism while maintaining high FPS on mobile browsers. * **Key Assets**: * **Vehicles**: Implement 3 distinct vehicle types: a Fast Sedan (high speed, low mass), a Pickup Truck (medium speed, high suspension), and a Battle Tank (slow, heavy, turret functionality). * **The Train**: An autonomous, unstoppable locomotive pulling cargo containers that follows a closed-loop railway track crossing the map. It acts as a moving hazard. * **Terrain**: A large, grassy plane (TerrainGeometry) with surrounding mountains (skybox or distant meshes). Include ramp structures and loops for stunts. * **Effects**: * **Destruction**: Mesh deformation or particle explosions upon high-velocity impact. * **Particles**: Dust trails when driving off-road, smoke when the engine is damaged, and explosion VFX for tank shots. * **Optimization**: Use `InstancedMesh` for foliage (grass/trees). Implement a fog system (`scene.fog`) to limit draw distance and save rendering resources. ### 2. Audio Requirements * **BGM**: High-energy, instrumental heavy rock or industrial electronic track that loops seamlessly. * **Sound Effects (SFX)**: * **Engine**: Dynamic pitch shifting based on vehicle speed. Distinct heavy rumble for the Tank vs. high-pitched whine for the Sedan. * **Collisions**: Metal crunching sounds varying in volume based on impact velocity. * **Train**: Rhythmic "chug-chug" sound with 3D positional audio (louder as it approaches) and a loud horn blast. * **UI**: Mechanical "click" sounds for buttons. ### 3. Gameplay Loop * **Core Mechanics**: * **Free Roam**: There is no timer. The player spawns in a vehicle and explores the map. * **Destruction Physics**: Utilizing a physics engine (like Cannon.js or Ammo.js), vehicles must react realistically to collisions. High-speed impacts cause visible damage or "wasted" states. * **Vehicle Switching**: Player can switch between the Car, Truck, and Tank instantly via a UI button. * **The Tank Mechanic**: When piloting the Tank, the player can fire explosive shells that push other objects or deform the terrain. * **Terraforming (Simplified)**: A toggleable "Build Mode" where players can tap to raise the ground to create improvised ramps, replicating the game's unique terraform feature. ### 4. Mobile Controls & Interaction * **Orientation**: **Landscape Mode** only. * **Driving Controls (Standard)**: * **Left Bottom**: Virtual Analog Joystick for steering (Left/Right). * **Right Bottom**: Distinct Pedal Buttons for Gas (Accelerate) and Brake/Reverse. * **Handbrake**: A smaller button near the brake pedal for drifting. * **Action Buttons (Right Side Cluster)**: * **Fire**: (Tank only) Large red button to shoot. * **Recover/Unflip**: A "Flip" icon to reset the car's rotation if upside down. * **Repair**: A "Wrench" icon to fix visual damage. * **Switch Car**: A cycle button to change current vehicle. * **Terraform Mode Toggle**: Top-right corner button to switch camera to overhead view for terrain modification. * **Feedback**: Trigger `window.navigator.vibrate(200)` on heavy collisions or explosions for haptic feedback. * **Camera**: Touch-and-drag anywhere on the center screen to orbit the camera around the vehicle. Pinch-to-zoom to adjust FOV. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
