Please use Three.js to generate a **mobile-first game** with the theme "**Classic Mahjong Solitaire**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Create a clean, sophisticated, semi-realistic 3D aesthetic. The game should feel like a premium board game. * **Tile Models:** Generate 3D Mahjong tiles with slightly rounded corners (bevel geometry). The tiles should have a dual-layer texture: an ivory-white top face for the symbol and a bamboo-green or amber backing. * **Tile Textures:** Use high-contrast procedural textures or canvas-drawn icons for standard Mahjong suites (Dots, Bamboo, Characters, Winds, Dragons, Flowers). The symbols must be sharp and legible on small mobile screens. * **Background:** Implement a deep green felt-like texture with a subtle, seamless traditional wave pattern (Seigaiha) to mimic a high-quality gaming table. This provides good contrast against the white tiles. * **Lighting:** Use soft, warm ambient lighting combined with a directional light casting subtle shadows to the bottom-right of each tile, enhancing depth perception without obscuring the symbols. * **Visual Feedback:** When a tile is selected, apply a subtle golden emissive glow or a slight lift animation (tween Y-position). When a match is made, emit a small particle burst (like sparkles or cherry blossom petals) before the tiles fade out. ### 2. Audio Requirements * **Background Music (BGM):** Synthesize a relaxing, Zen-inspired loop using traditional instruments like a Guzheng or Koto, mixed with soft ambient nature sounds (distant flowing water or wind chimes). It should be non-intrusive to aid concentration. * **Sound Effects (SFX):** * *Tap/Select:* A crisp "clack" sound, mimicking a hard resin tile hitting a wooden table. * *Match Success:* A harmonious pentatonic chime or a satisfying "click-lock" sound. * *Invalid Move:* A dull, wooden "thud" or a gentle error buzz. * *Shuffle/Hint:* The sound of multiple tiles being shuffled together. ### 3. Gameplay Loop * **Core Mechanic:** Implement standard Mahjong Solitaire (Shanghai) rules. Players must match pairs of identical "free" tiles to remove them from the board. A tile is "free" if it has no tile on top of it and possesses a free edge on either its left or right side. * **Level Layout:** Start with the classic "Turtle" or "Pyramid" formation, stacking tiles in 3D layers. Ensure the camera angle is isometric or top-down (approx 60-degree angle) to clearly show stacking depth. * **Timer & Scoring:** Include a countdown timer (e.g., 5 minutes). Award points for matches, with multipliers for speed (Combo chains). * **Win/Loss Condition:** * *Win:* All tiles are cleared from the board. * *Loss:* No more valid moves are possible, or the time runs out. * **Utilities:** Include a "Shuffle" button (rearranges remaining tiles if stuck) and a "Hint" button (highlights a valid pair). ### 4. Mobile Controls & Interaction * **Orientation:** Force **Landscape Mode** to maximize the playing area for the wide tile layout. * **Touch Input:** * Raycasting logic must be optimized for touch events (`touchstart` instead of just `click`). * Hit-testing precision is crucial; increase the invisible bounding box around tiles slightly to accommodate "fat finger" errors on smaller screens. * **Camera Controls:** Allow simple pinch-to-zoom and two-finger pan to help players see obscured tiles, but restrict the bounds so the board never leaves the screen. * **UI Layout:** * Place utility buttons (Pause, Shuffle, Hint) on the right edge or bottom corners, ensuring they are large (min 48x48px) and easily tappable with thumbs. * Display the Score and Timer clearly at the top center. * **Haptics:** Trigger a light vibration (using `navigator.vibrate`) upon successfully selecting a tile, and a slightly stronger vibration when a match is completed. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
