Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Copter.io". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Camera Perspective**: Use an `OrthographicCamera` positioned directly above the scene (Top-Down view) to replicate the classic 2D .io aesthetic shown in the screenshot. The camera must smoothly follow the player using linear interpolation (Lerp). * **Visual Style**: "Vector Flat" / "Paper-cut" aesthetic. Use simple geometries (Cylinders, Boxes) with `MeshToonMaterial` or `MeshBasicMaterial` for high performance. Colors should be vibrant and solid (Bright Blue/Red for players, Green for background). * **Player Character (Helicopter)**: Construct the helicopter using a Group of primitive shapes: a capsule/box for the body, and a thin box for the main rotor. **Crucial**: The main rotor must spin continuously on the Y-axis. Add a semi-transparent black plane underneath the helicopter to simulate a "drop shadow," creating a sense of altitude. * **Environment**: An infinite scrolling background using a seamless texture of a green grid (grass color #7BC74D with lighter grid lines). * **Enemies & Objects**: * **Tanks**: Stationary or slow-moving squares with a protruding "cannon" barrel. * **Drones**: Smaller, simpler flying triangles. * **XP Orbs**: Glowing circles (Yellow, Blue, Red) scattered across the map. * **Obstacles**: Simple grey crates (squares). * **Performance**: Use `InstancedMesh` for all bullets, XP orbs, and repetitive background elements to ensure 60 FPS on mobile devices. ### 2. Audio Requirements * **BGM**: An energetic, looping "Arcade / Drum & Bass" track with a fast tempo to keep adrenaline high. * **SFX**: * **Rotor**: A continuous low-humming *thwup-thwup-thwup* sound that varies slightly in pitch based on movement speed. * **Shooting**: Short, punchy synthesizer "pew" sounds. * **Explosion**: A retro-style "crackle-boom" when enemies or crates are destroyed. * **Level Up**: A rising, positive chime (Major chord arpeggio). * **Feedback**: A subtle "pop" sound when collecting XP orbs. ### 3. Gameplay Loop * **Core Mechanic**: The player pilots a helicopter in a large open arena. The goal is to survive and dominate. * **Progression**: Destroying crates, tanks, drones, and other players drops "XP Orbs". Collecting these fills a progress bar. Upon leveling up, the helicopter visually grows slightly larger, and the player gets a stats boost (Health, Damage, or Fire Rate). * **Combat**: * **Shooting**: Projectiles travel in a straight line with a limited range. * **Special Ability**: Every 10 seconds, the player can trigger a "Special" (e.g., a Grenade that explodes in an area or a momentary speed boost). * **Win/Loss**: * **Loss**: If HP reaches 0, the helicopter spins out of control and explodes. Show a "Game Over" screen with a "Respawn" button. * **Win (Session)**: Being #1 on the leaderboard (top right corner UI). ### 4. Mobile Controls & Interaction * **Control Scheme**: **Dual Virtual Joysticks**. * **Left Stick**: Controls movement (Translation on X/Z plane). * **Right Stick**: Controls aiming rotation and firing. Holding the stick in a direction rotates the helicopter and auto-fires bullets in that direction. Releasing stops firing. * **Special Ability Button**: A clearly visible circular button placed near the Right Joystick (easy reach for the thumb). * **Orientation**: **Landscape Mode** forced. * **UI Layout**: * **Health Bar**: Floating directly above the player mesh. * **Level/XP Bar**: Spanning the bottom center of the screen. * **Leaderboard**: Semi-transparent list in the top-right. * **Haptic Feedback**: Trigger a short vibration (`navigator.vibrate(20)`) when the player takes damage or destroys a significant enemy. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
