Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Classic Backgammon Online". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Photorealistic "Classic Board Room" aesthetic. Warm, rich color palette dominated by polished wood (mahogany, oak), gold accents, and deep felt reds/creams. * **Board Geometry**: A hinged wooden box model. The playing surface should feature the iconic 24 triangular "points" (alternating red and cream colors) inlaid into a wood texture. * **Game Pieces (Checkers)**: Simple CylinderGeometry for the checkers (15 Red/Dark Brown, 15 Cream/White). Add a slight bevel to edges to catch light. * **Dice**: Standard cubic dice with rounded corners. * **Lighting**: Use a warm PointLight to simulate a table lamp, casting soft shadows (ShadowMap enabled) to give depth to the stacked checkers. Add an AmbientLight to ensure no pitch-black shadows. * **Background**: A high-quality wood grain texture for the table surface underneath the board. * **Mobile Optimization**: Use low-polygon counts for cylinders (e.g., `radialSegments: 32`). Bake static shadows onto the board texture if possible to save performance, or use a single directional light for dynamic shadows. ### 2. Audio Requirements * **BGM**: A subtle, relaxing "Lounge Jazz" or "Acoustic Guitar" loop to evoke a sophisticated atmosphere. Volume should be low by default. * **Sound Effects (SFX)**: High-priority tactile feedback sounds: * *Dice Shake*: A rattling sound when the "Roll" button is pressed. * *Dice Roll*: Hard plastic hitting wood clatter. * *Checker Move*: A satisfying wooden "clack" or sliding sound when a piece lands on a point. * *Capture/Hit*: A distinct, sharper impact sound when a checker hits a lone opposing piece (sending it to the bar). ### 3. Gameplay Loop * **Game Modes**: Implement a main menu to choose between "vs CPU" (Single Player) and "Pass & Play" (Local Multiplayer). * **Core Mechanics**: * Turn-based logic. Players roll two dice to determine movement distance. * **Doubles**: If doubles are rolled (e.g., 6-6), the player gets 4 moves instead of 2. * **Movement Validation**: Pieces can only move to open points (points with 0 or 1 opposing checker). Points with 2+ opposing checkers are blocked. * **The Bar**: If a piece lands on a "blot" (single enemy piece), the enemy is sent to the "Bar" (center). Players on the Bar must enter the board before making other moves. * **Bearing Off**: Once all pieces are in the home quadrant, the player can start removing them from the board. * **Win Condition**: The first player to remove all checkers wins. ### 4. Mobile Controls & Interaction * **Camera Perspective**: Fixed, high-angle perspective (approx 60-70 degrees) to show the full board clearly without occlusion. * **Orientation**: **Landscape Mode** is mandatory to accommodate the wide aspect ratio of a Backgammon board. * **Input Method (Raycasting)**: * **Tap-to-Select**: Users tap a checker to select it. The checker should visually lift up slightly or glow (emissive material) to indicate selection. * **Highlight Valid Moves**: Upon selection, highlight valid destination triangles with a subtle green overlay or particle effect. * **Tap-to-Move**: Users tap the highlighted destination to execute the move. Avoid drag-and-drop mechanics as they can be finicky on mobile browsers; "Tap-Tap" is more precise. * **UI/UX**: * Large, thumb-friendly "ROLL DICE" button (floating UI, bottom right or center overlay). * Scoreboard and Current Turn indicator clearly visible at the top. * Ensure all touch targets are at least 44x44px. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
