Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Rovercraft: Space Engineer". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Side-Scroller aesthetic. Use an **Orthographic Camera** to simulate a flat 2D look while using 3D geometries. Apply **Toon Shading (Cel Shading)** to all models to mimic the vector art style of the screenshot (bright colors, clean edges). * **The Rover:** Construct a "modular" vehicle using primitive shapes (cubes for the chassis/cockpit, cylinders for wheels). The rover must visually represent distinct components: a cockpit (with a simple astronaut geometry), an engine block, a battery block, and high-traction tires. * **Terrain Generation:** Implement a procedural terrain generator (using Perlin noise or similar) that creates undulating hills, steep climbs, and drops. The ground should have a two-tone texture: grass/alien moss on top and soil/rock on the vertical sides. * **Background:** Create a parallax scrolling background with multiple layers (e.g., distant alien mountains, sci-fi structures/towers, and a sky gradient). * **Performance:** strict mobile optimization. Use a single shared geometry for repeated objects (like coins or rocks). Limit shadow casting to the Rover only. ### 2. Audio Requirements * **BGM:** An upbeat, adventurous "Space Arcade" track with synth-pop elements that loops seamlessly. * **Sound Effects (SFX):** * **Engine:** A continuous loop that changes pitch based on the rover's velocity/RPM. * **Suspension:** Squeaky mechanical sounds when the rover lands hard. * **Collectibles:** A high-pitched "ding" or digital chime when collecting coins. * **Failure:** A "crunch" metal sound and an explosion effect if the driver's head hits the ground. ### 3. Gameplay Loop * **Physics Engine:** Integrate **Cannon-es** (or a similar physics library compatible with Three.js) to handle vehicle dynamics. The rover is a complex rigid body with wheel constraints (HingeConstraints). **Crucial:** Lock the Z-axis position and X/Y-axis rotation of the main chassis to ensure strict 2D movement, but allow the rover to tilt (rotate around Z). * **Objective:** Drive as far as possible over procedurally generated, difficult terrain without flipping over or running out of energy. * **Resource Management:** Implement an "Energy/Fuel" bar that drains while accelerating. The player loses if energy reaches zero. * **Lose Condition:** If the Cockpit (top of the rover) collides with the Ground, the run ends immediately (Vehicle Destroyed). * **Win/Progress:** Collect coins scattered along the terrain to increase the score. ### 4. Mobile Controls & Interaction * **Screen Orientation:** Forced **Landscape Mode**. * **Touch Controls:** Implement a split-screen touch scheme: * **Left Screen Area (Touch & Hold):** Brake / Reverse / Air-rotate Left (Counter-Clockwise). * **Right Screen Area (Touch & Hold):** Gas / Accelerate / Air-rotate Right (Clockwise). * **Both Pressed:** Hard Brake/Stop. * **Visual Feedback:** Add simple on-screen button overlays (transparent sprites) that glow or shrink when pressed to provide visual confirmation of input. * **UI Layout:** * Top-Left: Distance Counter. * Top-Right: Coin Count. * Top-Center: Fuel/Energy Bar (Green to Red gradient). * **Reset Button:** A clearly visible "Restart" button (at least 44x44px) appearing only after a crash. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
