Please use Three.js to generate a **mobile-first game** with the theme "**Earn to Die: WebGL Wasteland**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: 2.5D Side-Scrolling perspective using a Low-Poly, Cel-Shaded art style to mimic the original game's comic book aesthetic while ensuring high performance on mobile devices. * **Lighting & Atmosphere**: A warm, post-apocalyptic sunset ambiance. Use an orange/red gradient Fog and HemisphereLight to match the screenshot's mood. Shadows should be sharp (hard shadows) for a gritty look. * **The Vehicle**: A rusty, modified red heavy truck. It must be composed of a chassis and separate wheel meshes to simulate suspension movement visually. Add a "spiked bumper" attachment to the front. * **The Terrain**: Infinite scrolling desert terrain with physics-based obstacles: jagged hills, wooden crates to smash, and ramps for jumping. * **The Zombies**: Low-poly green humanoid figures with simple walk animations. Upon impact, they should ragdoll or shatter into geometric "gore" chunks (red cubes) using a particle system. * **Performance**: Use `InstancedMesh` for repeating environment objects (rocks, cacti) and zombies. Limit texture sizes to 512x512. ### 2. Audio Requirements * **BGM**: A looping, high-energy Heavy Rock/Metal track with distorted guitars and driving drums to pump up the player's adrenaline. * **Sound Effects (SFX)**: * **Engine**: A deep rumble that increases in pitch as the vehicle accelerates. * **Impact**: A wet "squish" sound mixed with a crunchy impact sound when hitting zombies. * **Environment**: Wood splintering sounds when smashing crates; metal scraping sounds upon hard landings. * **UI**: A metallic "clank" for menu selection and a "cash register" 'cha-ching' sound when earning money at the end of a run. ### 3. Gameplay Loop * **Core Mechanism**: A physics-based "distance runner." The player drives from left to right, managing fuel and vehicle stability. * **The Run**: The player presses "Gas" to accelerate. The vehicle consumes fuel over time. Hitting zombies slows the car slightly but grants money. * **Physics & Balance**: The car must traverse uneven terrain. The player must use tilt controls to land flat after jumps. If the car flips upside down, the run ends instantly. * **Upgrade Loop**: * At the end of a run (Out of fuel or flipped), a summary screen shows "Distance Traveled" and "Zombies Killed." * Money is awarded based on these stats. * **Shop Scene**: Between runs, allow players to spend money to upgrade: Fuel Tank (duration), Engine (speed), Tires (grip), or Thruster (boost). * **Progression**: The goal is to reach a fixed distance (e.g., 3000m) to unlock the next level/helicopter. ### 4. Mobile Controls & Interaction * **Screen Orientation**: Landscape Mode (Force landscape logic in CSS/JS). * **Touch Controls**: * **Bottom Right**: A large, circular "Gas" button (Hold to drive). A smaller "Boost" button above it (Active only when upgrade purchased). * **Bottom Left**: Two arrow buttons (Left/Right) to control the car's pitch/rotation while in the air (Tilting). * **UI/UX**: * **HUD**: A fuel gauge bar at the top center (turning red when low) and a speedometer. * **Feedback**: Trigger `navigator.vibrate(50)` on mobile devices when smashing through a zombie or landing a jump. * **Touch Targets**: Ensure all UI buttons are at least 48x48 pixels with distinct pressed states (scaling down or changing color). Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
