Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Space Alien Invaders". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Classic Arcade Retro Pixel Art. Use an Orthographic Camera to maintain a crisp 2D perspective within the 3D scene. * **Asset Generation:** Instead of loading external images, please use `CanvasTexture` to procedurally draw the pixel art sprites (Spaceship, Aliens, Bunker blocks) onto `THREE.Sprite` or `THREE.PlaneGeometry`. * **Player Ship:** White/Grey pixel design with a flickering orange thruster at the bottom. * **Aliens:** Three distinct variations (Crab-like, Squid-like, Octopus-like) in colors Green (`#00FF00`), Cyan (`#00FFFF`), and Magenta (`#FF00FF`). They should have a simple 2-frame animation toggled by swapping textures. * **Background:** A deep black void with a "Starfield" particle system. Stars should have different depths and move slightly (parallax effect) opposite to player movement to create depth. * **Post-Processing (Optional but recommended):** A subtle "Bloom" effect (UnrealBloomPass) to make the neon pixel colors glow against the black background, enhancing the "Arcade Cabinet" feel. * **Mobile Optimization:** Use **Object Pooling** for projectiles (lasers) and particle explosions to ensure 60FPS on mobile devices. Limit max active particles. ### 2. Audio Requirements * **BGM:** A driving, fast-paced 8-bit Chiptune loop (synthesized using `AudioContext` oscillator nodes to avoid loading files). It should feel tense and rhythmic. * **SFX:** * **Shoot:** A short, high-pitched square wave "Pew" sound. * **Explosion:** A decaying white noise burst for enemy deaths. * **UFO:** A high-frequency warbling sine wave when the special saucer appears. * **Game Over:** A descending sad melody. ### 3. Gameplay Loop * **Core Mechanics:** The player controls a ship at the bottom of the screen, moving only along the X-axis. * **Enemies:** A grid of aliens starts at the top and moves horizontally. When they hit the screen edge, they drop down one row and reverse direction. Their speed increases as their numbers decrease. * **Combat:** * Player shoots vertical lasers to destroy aliens. * Aliens randomly drop bombs/lasers downwards. * **Mystery Ship:** Occasionally, a Red UFO flies across the very top for bonus points. * **Win/Loss:** * **Loss:** If an alien touches the player ship, or if the alien grid reaches the player's Y-level. * **Win/Survival:** Clearing a wave resets the grid but increases the base speed (Infinite Survival Mode). ### 4. Mobile Controls & Interaction * **Screen Orientation:** **Landscape Mode** is preferred to match the classic arcade ratio. * **Touch Controls (Slider Mechanism):** * Implement an invisible "Touch Zone" covering the bottom half of the screen. * **Drag:** Touching and dragging left/right moves the ship. The ship should follow the finger's X-position relative to the screen width (1:1 movement or slight inertia). * **Auto-Fire:** The ship should automatically fire its weapon continuously (e.g., every 0.5s) as long as the user is touching the screen. This is more ergonomic for mobile than a separate button. * **UI Layout:** * **Score:** Large, blocky font at the top left. * **Start/Restart Button:** A large, pulsing centered button (minimum 60x60px touch area) overlaying the screen when the game is paused or over. * **Feedback:** Add a subtle "Screen Shake" effect (camera jitter) when the player gets hit or a large explosion occurs to provide tactile visual feedback. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
