Please use Three.js to generate a **mobile-first game** with the theme "Mahjong Black White 2 Untimed". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Tile Models:** Generate 3D Mahjong tiles using `THREE.BoxGeometry` with slightly rounded edges (chamfered) for a premium feel. * **Material & Texture Style:** * **The Twist:** Half the tiles must use a **White material** (glossy plastic finish), and the other half must use a **Black material** (matte or slight sheen). * **Symbols:** Use standard Mahjong unicode characters or placeholder textures (Bamboo, Dots, Characters, Winds, Dragons, Flowers, Seasons) applied to the top face. Ensure symbols are colored (Red, Green, Blue) to contrast clearly against both black and white backgrounds. * **Background/Scene:** Create a "Celestial Dream" atmosphere based on the reference. Use a dark blue radial gradient background or a starry skybox. Add a subtle, static 3D rainbow arc geometry in the far background or a particle system simulating slow-moving stardust. * **Optimization:** Use InstancedMesh for the tiles to reduce draw calls (critical for mobile performance). Use low-poly geometry for the environment. ### 2. Audio Requirements * **BGM:** A relaxing, ambient "Zen" track. Think slow-tempo piano or harp with soft synthesizer pads to support the "Untimed/Casual" nature of the game. * **SFX:** * *Selection:* A soft wooden "clack" sound when tapping a tile. * *Match:* A magical "chime" or satisfying "pop" sound. * *Error/Invalid Move:* A subtle low-pitched "thud" or vibration. * *Shuffle/Undo:* A rushing sound like tiles sliding on a table. ### 3. Gameplay Loop * **Core Mechanic:** Standard Mahjong Solitaire rules (tiles must be free on the left or right and have no tile on top). * **The Unique Rule (Crucial):** Matches are **ONLY** valid between one **Black Tile** and one **White Tile** of the same symbol. * *Example:* Black 5-Bamboo + White 5-Bamboo = Valid. * *Invalid:* White + White or Black + Black is forbidden. * **Special Tiles:** Flower and Season tiles can match any other tile in their respective category, regardless of the specific picture, but must still adhere to the Black/White color rule. * **Win/Lose Logic:** * *Win:* Clear all tiles from the board. * *Stuck:* If no moves are possible, automatically prompt the user to use the "Shuffle" function. * **Tools:** Implement "Undo" (revert last move) and "Shuffle" (rearrange remaining tiles) functionality. ### 4. Mobile Controls & Interaction * **Camera:** Fixed Isometric view (approx 45 degrees), auto-scaled to fit the tile layout within the screen width (portrait or landscape). * **Touch Interaction:** * Use `Raycaster` for precise touch detection. * **Selection State:** When a tile is tapped, highlight it with a glowing outline (e.g., Yellow emission) and lift it slightly on the Y-axis (+0.2 units) to prevent obstruction by finger. * **Auto-Deselect:** Tapping the background or an invalid tile should deselect the current tile. * **UI Layout:** * Place "Undo", "Shuffle", and "Level Select" buttons at the bottom of the screen (thumb-friendly zone). * Buttons should be at least 44x44 pixels for touch targets. * **Feedback:** Trigger `window.navigator.vibrate(50)` (haptic feedback) on successful matches if supported by the device. Add a particle explosion effect at the location of the match. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
