VR Arcade

Welcome to VR Arcade, an interactive Virtual Reality project built in Unity. This project serves as a sandbox for various VR mechanics, physical interactions, and AI integrations, all housed within a central virtual arcade room.

Features & Mini-Games

The project utilizes the Unity XR Interaction Toolkit to provide smooth headset tracking, locomotion, and hand/controller interactions across several distinct experiences.

♟️ VR Chess against Stockfish

A fully playable, physically interactive chess game located in the main arcade room.

• Stockfish AI: Uses the world-class Stockfish engine running as a background process to calculate moves.
• Adjustable Difficulty: Configurable AI profiles ranging from beginner to Grandmaster (Levels 1-10), with adjustable search depths and think times.
• VR Mechanics: Players can physically grab and place chess pieces. Illegal moves are automatically rejected, and the piece smoothly animates back to its original square.
• Full Chess Rules: Fully supports castling, en passant, pawn promotion (with VR UI panels), and 50-move/threefold repetition draw detection.

🎳 Bowling Alley

A physical bowling simulator where players can grab, aim, and throw a bowling ball down the lane.

• Dynamic Audio: The bowling ball plays realistic rolling sounds when moving across the floor and hit sounds upon colliding with pins.
• Automatic Scoring: A live scoreboard tracks how many pins have been knocked down.
• Quick Reset: A dedicated reset button clears the lane, respawns a fresh set of pins, and resets the score to zero.

❌⭕ Tic-Tac-Toe vs Minimax AI

A spatial version of the classic game.

• Minimax Algorithm: The AI opponent uses the Minimax algorithm to ensure it never loses.
• Physical Input: Players make their moves by physically colliding with the designated cubes on the board.
• Auto-Reset: The game detects wins, losses, or ties and automatically resets the board after a brief delay.

🎯 Physics Experiments & Toys

• Sticky Arrows: An archery-style physics script (stick.cs) that causes objects to freeze and stick perfectly to any surface they collide with, aligning to the surface normal.
• Procedural Generation: A chessboard generator (board_maker.cs) that spawns the board piece-by-piece in a nanobot-style assembly animation.

Getting Started

1. Requirements: Unity Editor (configured for VR development), a compatible VR Headset (e.g., Meta Quest), and the Oculus/XR Interaction Toolkit packages installed.
2. Main Scene: Open Assets/Scenes/main.unity to explore the primary VR Arcade Room which houses the Chess and Bowling experiences.
3. Prefabs: Additional games like Tic-Tac-Toe can be found in the Assets/prfaps folder and dropped into any scene.

Technologies Used

• Unity Engine
• Unity XR Interaction Toolkit
• Meta Voice SDK / Oculus Integration
• Stockfish Chess Engine (Executable integrated via standard I/O streams)
