Rally Point 2 - Free Racing Game - Racing Game

Please use Three.js to generate a **mobile-first game** with the theme "Rally Point 2 - Winter Drift Edition". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Mid-poly 3D Arcade Racing. The aesthetic should be gritty but vibrant, emphasizing speed. * **Key Asset (Player Car)**: A red, hatchback rally car (resembling a Mini Cooper) with the number "38" on the back. It must feature dual exhaust pipes that emit bright blue particle flames when Nitro is active. * **Environment**: A winter snowy track. Use white/blue-tinted terrain textures. * **Decor**: Low-poly pine trees (billboarded for mobile performance), wooden fences lining the curves, and a "Start/Finish" wooden archway. * **Lighting**: Ambient blue-ish light with a directional sun casting soft shadows. * **VFX**: * **Nitro**: Intense blue trail/flame particles behind the car. * **Drifting**: White snow dust particles generated from rear tires when turning sharply. * **Speed**: Camera FOV should widen significantly when Nitro is active to simulate high speed. * **Optimization**: Use simple geometry for collision (AABB or Sphere), reuse materials, and limit particle count (max 50 active particles) for smooth FPS on mobile devices. ### 2. Audio Requirements * **BGM**: High-energy, fast-paced Electronic Rock or Breakbeat track to induce adrenaline. * **Sound Effects (SFX)**: * **Engine**: Constant engine hum, pitch-shifting higher as speed increases. * **Nitro**: A sharp "whoosh" or jet-engine sound when the boost button is pressed. * **Drift**: Muffled tire scrubbing sound (distinct from asphalt screeching, as it is on snow). * **UI**: Mechanical clicks for menus; a countdown beep (3, 2, 1, GO). ### 3. Gameplay Loop * **Core Mode**: Time Attack. The player must reach the finish line before the timer runs out. * **Mechanics**: * **Driving**: Arcade physics. High grip normally, but "Drift" button loosens traction to allow sliding around corners. * **Nitro System**: Player has a Nitro gauge. Holding the Nitro button provides a massive speed boost and blue flame visuals. *Constraint*: If Nitro is held too long (overheating), the car spins out or explodes (game over). * **Progression**: Successfully beating the target time unlocks the "Next Track" (procedurally generate a slightly harder curve layout). * **Win/Loss**: * **Win**: Cross finish line under target time. * **Loss**: Time runs out OR car overheats from excessive Nitro. ### 4. Mobile Controls & Interaction * **Orientation**: Landscape Only. * **Touch Controls (UI Overlay)**: * **Left Side**: Two large arrows (Left / Right) for steering. * **Right Side**: * **Drift Button (X)**: Positioned for thumb access. * **Nitro Button (Z)**: Larger, distinct button (Red or Glowing Blue). * **Top Center**: Reset Car button (R icon) in case of getting stuck. * **Feedback**: * **Haptic**: Trigger device vibration (navigator.vibrate) when crashing or igniting Nitro. * **Visual**: Screen shake effect when using Nitro or hitting an obstacle. * **UI Layout**: Keep score/timer in top corners. Ensure all touch targets are at least 48x48px with ample spacing to prevent mis-clicks. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
