Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Jetpack Joyride - Infinite Lab Runner**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Side-Scroller. Use a **Low-Poly Cartoon aesthetic** with vibrant colors (ToonShader or MeshToonMaterial) to mimic the original 2D art style in 3D. * **Player Character:** A stylized, blocky character (representing Barry) equipped with a "Machine Gun Jetpack." * **Environment (The Lab):** An infinite scrolling corridor. * **Foreground:** The floor and ceiling should be metallic grey tiles. * **Background:** A scrolling wall with depth details like pipes, vents, and "Sector" numbers to create a parallax effect. * **Obstacles:** * **Zappers:** Rotating electric beams (yellow/blue glowing cylinders) placed at varying heights. * **Missiles:** Red rockets that fly horizontally across the screen. * **Collectibles:** Floating gold coins (use `InstancedMesh` for performance optimization on mobile). * **Visual Effects (Particles):** * **Jetpack Thrust:** Instead of fire, the jetpack must emit a stream of "bullets" and "shell casings" downwards when activated, acting as the visual propulsion. * **Explosions:** Simple expanding sphere particles when the player hits an obstacle. ### 2. Audio Requirements * **BGM:** A high-energy, driving industrial-rock or fast-paced synth track that loops seamlessly. * **Sound Effects (SFX):** * **Jetpack:** A rapid-fire "rat-a-tat-tat" machine gun sound that plays *only* when the screen is touched (flying). * **Coins:** A satisfying high-pitched "ding" or "ching" sound. * **Death:** A Zap sound (electric) or Explosion sound. * **Missile Warning:** A beeping alarm sound before a missile enters the screen. ### 3. Gameplay Loop * **Core Mechanics:** The character automatically runs to the right (or rather, the world moves left). * **Physics:** * **Gravity:** Constant downward force pulling the character to the floor. * **Thrust:** When the player touches the screen, apply upward velocity. Visuals: The character rises, and bullets shoot downwards impacting the floor/enemies. * **Enemies & Hazards:** * **Scientists:** Tiny NPCs running on the ground (purely cosmetic, they scatter when the player flies over). * **Zappers:** Static or rotating electric fields. Contact = Instant Game Over. * **Missiles:** A "!" warning icon appears on the right edge of the screen for 2 seconds, followed by a missile speeding across. * **Scoring:** Score increases based on distance traveled (meters). Bonus points for collecting coins. * **Game Over:** When colliding with a Zapper or Missile, the character ragdolls or explodes, the run ends, and a "Retry" screen appears. ### 4. Mobile Controls & Interaction * **Control Scheme:** **One-Touch Gameplay**. * **Action:** Touch and hold *anywhere* on the screen to activate the jetpack (ascend). Release to de-activate (descend/fall). * **Screen Orientation:** Forced **Landscape Mode** is preferred for the side-scrolling view, but the camera FOV should adapt if the user is in Portrait (zoom out slightly). * **UI/UX:** * **HUD:** Display "Distance" (top left) and "Coins" (top right) with large, readable fonts. * **Start/End Screen:** A large, central "Play" / "Play Again" button (minimum 60x60px touch target). * **Feedback:** * **Camera Shake:** Slight camera shake when the player hits the ceiling or gets hit by a missile. * **Haptic Feedback:** If supported (Navigator.vibrate), trigger a short vibration on death. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
