Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Chess Online Multiplayer - Stylized 3D Edition**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Adopt a "Clean Casual 3D" aesthetic similar to the promotional banner. Use smooth, matte materials (MeshStandardMaterial) for chess pieces rather than realistic wood. * **Pieces**: Use combined Three.js primitives (Cylinders, Spheres, Cones) to procedurally generate stylized representations of Pawn, Rook, Knight, Bishop, Queen, and King. * **Color Palette**: Player 1 (Cream/White), Player 2 (Charcoal Black). * **Board**: A 3D board with alternating tile colors. Default to the banner's color scheme: Cyan/Teal and Dark Blue tiles. * **Environment**: A solid or gradient background color (Royal Purple to Teal gradient) to match the "casual/arcade" vibe. * **Lighting**: Soft 3-point lighting setup to create gentle shadows and highlight the curvature of the pieces (AmbientLight + DirectionalLight). * **Performance**: Use instanced rendering (`InstancedMesh`) for the board tiles if possible to reduce draw calls. Limit shadow map resolution for mobile performance. ### 2. Audio Requirements * **BGM**: A relaxing, looping "Lo-Fi Hip Hop" or "Lounge Jazz" track to aid concentration without being distracting. * **Sound Effects (SFX)**: * **Piece Select**: A soft "pop" or high-pitched "tick". * **Move/Place**: A satisfying, tactile "thud" or "clack" simulating a piece hitting the board. * **Capture**: A more distinct, heavier impact sound or a shattering glass sound effect. * **Check/Checkmate**: A dramatic chime or warning tone. * **UI Interaction**: Crisp clicking sounds for menu buttons. ### 3. Gameplay Loop * **Core Logic**: Implement standard International Chess rules. * Support legal move validation (highlight valid squares when a piece is selected). * Implement Special Moves: Castling, En Passant, and Pawn Promotion (auto-promote to Queen for simplicity in this prototype). * **Game Modes**: 1. **PvE (Player vs CPU)**: A basic Minimax algorithm or Random Mover for the opponent. 2. **PvP (Hotseat)**: Local multiplayer where the camera rotates 180 degrees after each turn. * **Economy & Shop (UI Simulation)**: * Winning a match awards "Gold". * Include a simple "Shop" UI overlay allowing the user to swap board colors (e.g., switch from Teal to Wood texture) using earned Gold. ### 4. Mobile Controls & Interaction * **Camera**: Fixed Isometric view or high-angle Perspective view. The board should fit perfectly within the width of a portrait mobile screen. * **Input System**: * **Raycasting**: Use `THREE.Raycaster` to map touch inputs to board squares. * **Drag & Drop vs. Tap-Tap**: Implement a **Tap-to-Select, Tap-to-Move** system as it is more precise than dragging on small screens. * **Visual Feedback**: * **Selection**: When a piece is tapped, it should slightly levitate (move up Y-axis) and glow. * **Valid Moves**: Highlight target squares with small glowing spheres or change the tile emission color. * **Last Move**: Highlight the start and end squares of the opponent's last move. * **UI Layout**: * All UI buttons (Reset, Menu, Undo) must be at the bottom or top of the screen, avoiding the center play area. * Button size minimum: 44x44 pixels for touch accessibility. * Include a "Turn Indicator" text (e.g., "White's Turn"). Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
