Please use Three.js to generate a **mobile-first game** with the theme "**Robot Dinosaur Space Shooter**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Side-Scrolling Arcade Shooter. The aesthetic should be "Flash Game Retro" mixed with "Low-Poly Sci-Fi". * **Player Model (The Robo-Dino):** Construct a stylized T-Rex using basic Three.js primitives (BoxGeometry, CylinderGeometry). * **Body:** Metallic silver/grey material. * **Accessories:** A jetpack on the back that emits a continuous particle system (orange/red squares) to simulate exhaust/fire. * **Animation:** A simple bobbing animation (sinusoidal wave) to simulate hovering flight. * **Enemies:** * **UFOs:** Red and Grey flattened cylinders (discs) representing the saucers in the screenshot. * **Energy Orbs:** Rotating Spheres with an emissive glowing material (Yellow/Pink) pulsing with light. * **Environment:** * **Background:** A deep navy blue background color (`0x050520`). * **Starfield:** A particle system of white dots moving from right to left to create a parallax effect, simulating high-speed flight through space. * **Performance:** Use `InstancedMesh` for the starfield and enemy projectiles if possible to maintain 60 FPS on mobile devices. ### 2. Audio Requirements * **BGM:** A high-energy, loopable track combining **8-bit Chiptune** melodies with **Heavy Metal** guitar riffs (simulated or suggested placeholder) to match the absurdity of a robot dinosaur. * **Sound Effects (SFX):** * **Jetpack:** A continuous low-hum or white noise loop when the player is ascending. * **Roar/Laser:** A synthesized "Roar" sound blended with a high-pitched laser zap when firing. * **Explosion:** A retro "crunch" sound when enemies are destroyed. * **UI:** Crisp "blip" sounds for button presses. ### 3. Gameplay Loop * **Core Mechanic:** The game is an endless side-scroller. The screen auto-scrolls. The player must survive as long as possible. * **Movement Physics:** "Jetpack Joyride" style physics. * **Gravity:** Constantly pulls the dinosaur down. * **Thrust:** Holding the thrust control pushes the dinosaur up. * **Combat:** * **Shooting:** When the player activates the attack, a wide, red rectangular beam (Laser) extends instantly from the dinosaur's mouth to the right edge of the screen. * **Hit Detection:** Raycasting or simple AABB collision detection. The laser destroys any enemy in its path instantly. * **Win/Loss:** * **Health:** The player has 3 Health Points (HP). Colliding with an enemy reduces 1 HP. * **Game Over:** When HP reaches 0, the dino explodes (particle effect), and a "Retry" screen appears. * **Score:** +100 points for every enemy destroyed; +1 point for every second survived. ### 4. Mobile Controls & Interaction * **Orientation:** **Landscape Mode** (Force landscape if possible via CSS). * **Touch Controls (Split Screen):** * **Left Half of Screen:** **Thruster Control**. Touch and hold anywhere on the left side to fly up. Release to fall. * **Right Half of Screen:** **Roar/Fire Button**. Tap anywhere on the right side to fire the laser beam. * **Visual Feedback:** * When the "Thruster" is active, the jetpack particle stream should intensify. * When "Fire" is tapped, the dinosaur's head should slightly recoil, and the screen should shake briefly (camera shake effect). * **UI Elements:** * **HUD:** Top-left: Score (Large Retro Font). Top-right: Health Hearts. * **Touch Targets:** Ensure the "Retry" button on the Game Over screen is at least 44x44 pixels and centered for easy thumb access. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
