Please use Three.js to generate a **mobile-first game** with the theme "**Backgammon Online: Classic 3D Board**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Realistic but clean aesthetic, simulating a high-quality wooden board game. Use warm color palettes (mahogany, oak, creamy white, deep red). * **Board Model**: Create a hinged wooden case structure. The playing surface should feature 24 elongated triangular "points" (alternating dark red and cream/white). * **Game Pieces**: * **Checkers**: Simple low-poly cylinders with a slight bevel. 15 Red pieces and 15 White pieces. Texture should resemble smooth plastic or painted wood. * **Dice**: Standard cubes with rounded edges and clearly visible pips. * **Doubling Cube**: A larger die placed on the side rail (visual prop). * **Lighting**: Use a warm Directional Light to cast soft shadows (simulating a table lamp) and an Ambient Light to ensure visibility. * **Performance**: Use `InstancedMesh` for the checkers and points to minimize draw calls. Limit texture resolution to 1024x1024. Use simple Phong materials for performance on mobile devices. * **Camera**: Fixed perspective camera positioned at a high angle (approx 60 degrees), optimized for **Portrait Mode** (vertical) to fit the long board layout on mobile screens naturally. ### 2. Audio Requirements * **BGM**: A loop of smooth, relaxing **Lounge Jazz** or **Coffee Shop Ambience** (piano and soft bass) to evoke a casual, sophisticated atmosphere. * **Sound Effects (SFX)**: * *Dice Roll*: A realistic rattling sound followed by the thud of dice hitting the wood. * *Checker Move*: A satisfying wooden "clack" or sliding sound when a piece lands. * *Capture/Hit*: A distinct, slightly sharper impact sound when a checker hits a blot. * *UI Interaction*: Soft clicks for button presses. * *Win/Lose*: A short jazz flourish or triumphant chord. ### 3. Gameplay Loop * **Setup**: Initialize board with standard Backgammon setup (24 points, specific starting positions for 15 checkers per player). * **Turn Sequence**: 1. **Roll**: Player taps to roll two dice. Logic handles random number generation (1-6). 2. **Move Calculation**: System highlights valid moves based on dice values. Logic must handle: * Standard moves (open points or own points). * Blocked points (points with 2+ opponent checkers). * "Hitting" a blot (opponent has 1 checker). * **Doubles**: If dice are equal, player gets 4 moves. 3. **The Bar**: If a player has checkers on the "Bar" (hit by opponent), they *must* re-enter the board before moving other pieces. 4. **Bearing Off**: Logic to allow removing pieces only when all checkers are in the home quadrant. * **Win Condition**: The first player to remove all 15 checkers from the board wins. ### 4. Mobile Controls & Interaction * **Input Method**: **Tap-to-Select, Tap-to-Move** system (avoid drag-and-drop to prevent the user's finger from blocking the view of the destination). * **Raycasting**: precise hit detection for the small checker geometries. * **Visual Feedback**: * When a checker is selected, **highlight** valid destination triangles in Green and invalid ones in Red. * When a checker is captured, animate it moving to the "Bar" (center of the board). * **UI Layout**: * Place the "Roll Dice" button large and at the bottom center (thumb-friendly zone). * Display player turn and score clearly at the top. * Ensure all touch targets are at least 44x44 pixels. * **Haptics**: Trigger a short vibration (using `navigator.vibrate`) when a piece lands or captures an opponent. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Mechanics

Basic Movement Rules

Each turn begins with rolling two dice. You can move your checkers based on the dice values in several ways: - Move one checker the total distance of both dice - Split the moves between two different checkers - When you roll doubles, you get four moves instead of two

Strategic Positioning

Checkers can only move to: - Empty points (triangular spaces) - Points occupied by your own checkers - Points with only one opposing checker (which you can capture)

Points with two or more opponent checkers are blocked and cannot be entered.

Capturing and Re-entry

When you land on a point occupied by a single opponent checker, you capture it. The captured checker must re-enter the game from the beginning, adding strategic depth to every move.
