Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Jetpack Joyride". 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 an **Orthographic Camera** to mimic the classic flat cartoon look but with 3D depth. * **Character (Barry)**: A low-poly 3D character model wearing a blue suit and a machine-gun jetpack. Apply a **Toon Shader (Cell Shading)** to replicate the comic book art style seen in the reference image. * **The Lab (Environment)**: A procedural, infinite scrolling background consisting of laboratory walls, metal pipes, and warning lights. Use **Parallax Scrolling** layers (foreground props, mid-ground action, background walls) to create depth. * **Particle Effects**: * **Jetpack Propulsion**: Instead of fire, the jetpack emits a rapid stream of **bullet casings and muzzle flashes** downward. * **Smoke**: Trail effects when the player rises. * **Coin Sparkles**: Visual feedback when collecting coins. * **Mobile Optimization**: Implement **Object Pooling** for bullets, coins, and obstacles to prevent garbage collection stutter on mobile devices. Limit draw calls by merging static environment geometries. ### 2. Audio Requirements * **BGM**: A high-energy, fast-paced "Secret Agent / Surf Rock" electronic track that loops seamlessly. * **SFX - Jetpack**: A rapid-fire machine gun sound effect that plays continuously *only* while the screen is touched (ascending). * **SFX - Interaction**: * Satisfying high-pitched "Ding" for coin collection. * Electrical "Buzz" for Zapper obstacles. * "Crash/Explosion" sound for game over. * "Splat" sound if bullets hit the running scientists on the ground. ### 3. Gameplay Loop * **Core Mechanics**: The character runs automatically to the right. * **Ascend**: Player applies thrust (jetpack fires bullets down), pushing the character up. * **Descend**: Gravity pulls the character down when input is released. * **Obstacles**: * **Zappers**: Stationary or rotating electric beams (require precise height control to dodge). * **Missiles**: Warning icon appears on the right edge, followed by a fast-moving missile flying horizontally. * **Laser Beams**: Lines that appear and then activate across the screen. * **Scoring**: * **Distance**: Score increases based on meters traveled. * **Coins**: Floating coin patterns (sine waves, lines) that add to a separate currency counter. * **Difficulty**: The scrolling speed gradually increases the further the player survives. * **Game Over**: Direct collision with a Zapper, Missile, or Laser ends the run instantly. ### 4. Mobile Controls & Interaction * **Input Method**: One-touch control scheme. * **Touch Start / Hold**: Activate jetpack (add vertical velocity, play machine gun sound/anim). * **Touch End**: Deactivate jetpack (let gravity take over). * **Screen Orientation**: Force **Landscape Mode** for the best field of view. * **Responsiveness**: * Physics must feel "heavy" but responsive. Upward acceleration should not be instant; it requires momentum. * Prevent default browser behaviors (like scroll-to-refresh or zooming) on the canvas. * **UI/UX**: * **HUD**: Large, legible fonts for "Distance" (top left) and "Coins" (top right). * **Menus**: A large "Tap to Play" overlay at the start and a "Retry" button (minimum 44x44px hit area) on the Game Over screen. * **Feedback**: Trigger a short vibration (Haptic Feedback) via `navigator.vibrate(200)` upon death. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
