Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Chess Free - 3D Classic". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Photorealistic "Classic Staunton" aesthetic, mimicking the provided reference image. The board and pieces should feature high-quality wood textures (e.g., polished dark walnut for black pieces/squares and light maple for white pieces/squares). * **Camera & Lighting**: Use a cinematic perspective camera that allows for a slight angle (not purely top-down) to show piece depth, with a "Depth of Field" effect (blurring the background). Lighting should be warm and focused (spotlights) to create dramatic shadows and highlights on the glossy wood surfaces. * **Environment**: A dark, blurred background (e.g., a cozy study room or abstract dark gradient) to keep the focus strictly on the board. * **Optimization**: Use **InstancedMesh** for the pawns and repeated geometries to reduce draw calls. Texture resolution should be optimized for mobile (max 1024x1024 for the board, 512x512 for pieces). ### 2. Audio Requirements * **BGM**: A quiet, sophisticated ambient track—slow jazz piano or classical acoustic guitar—that aids concentration. * **Sound Effects (SFX)**: * **Selection**: A subtle "swish" or lifting sound. * **Move/Drop**: A satisfying, crisp "wooden clack" or "thud" varying slightly in pitch based on the speed of the move. * **Capture**: A slightly louder, more aggressive impact sound. * **Check/Checkmate**: A distinct chime or dramatic chord. * **UI Feedback**: Soft clicks for menu buttons (Undo, Hint). ### 3. Gameplay Loop * **Core Mechanics**: Standard FIDE chess rules. * **Turn System**: White moves first, alternating turns. * **Valid Moves**: When a piece is selected, calculate and visualize all legal moves based on the piece type (Pawn, Rook, Knight, Bishop, Queen, King). * **Special Moves**: Implement logic for **Castling** (King side/Queen side), **En Passant**, and **Pawn Promotion** (auto-promote to Queen for simplicity, or simple UI to choose). * **Game Modes**: * **PvE**: A simple Minimax algorithm or random-move AI for the "Computer" opponent (Beginner difficulty). * **Local PvP**: Pass-and-play functionality. * **Win/Loss Conditions**: Checkmate (Win/Loss), Stalemate (Draw), Draw by insufficient material. * **Auxiliary Features**: * **Undo**: Ability to revert the last move (stack-based history). * **Hints**: Highlight the "best move" for the current player upon request. ### 4. Mobile Controls & Interaction * **Control Scheme**: Raycasting-based interaction. * **Primary**: **Drag and Drop**. The player touches a piece, drags it across the board (piece should float slightly above the board), and releases it on a valid square. * **Secondary (Fallback)**: "Tap to Select" -> "Tap to Move" for better precision on smaller screens. * **Visual Feedback**: * **Highlights**: Use glowing rings or semi-transparent planes to show: Selected Piece (Blue), Valid Moves (Green dots), Capture Targets (Red), and Previous Move (Yellow tint). * **Haptic Feedback**: Trigger `navigator.vibrate(50)` on piece drop and capture events. * **UI & Layout**: * **Orientation**: Portrait mode preferred for mobile (board centered, UI below), but responsive to Landscape. * **Touch Targets**: UI buttons (Undo, Restart, Hint) must be at least 44x44px. * **Camera Control**: Allow single-finger orbit (limited angle) and two-finger pinch to zoom, but auto-reset camera on turn change. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Gameplay Mechanics

Basic Chess Rules

Chess Free follows standard international chess rules. The objective is to checkmate your opponent's king by putting it in a position where it cannot escape capture. Each piece has unique movement patterns:

  • Pawns : Move forward one square, capture diagonally
  • Knights : Move in an L-shaped pattern (2+1 squares)
  • Bishops : Move diagonally any number of squares
  • Rooks : Move horizontally or vertically any number of squares
  • Queen : Combines rook and bishop movements
  • King : Moves one square in any direction

Special Moves

Castling : A defensive move involving the king and rook, allowed only when specific conditions are met (neither piece has moved, no pieces between them, king not in check).

En Passant : A special pawn capture that can occur when an opponent's pawn moves two squares forward and lands adjacent to your pawn.

Strategic Elements

Success in chess requires strategic thinking, pattern recognition, and tactical awareness. Control the center of the board, protect your pieces, and always anticipate your opponent's potential moves. The game ends in victory through checkmate, or can result in a draw through stalemate, repetition, or insufficient material.
