Project Overview

The Multiplayer Pool Game (8-Ball) is a web-based billiards simulation where two players compete online following standard 8-ball pool rules. The project focuses on realistic ball physics, real-time multiplayer gameplay, and interactive UI/UX, making it a challenging and fun final-year Computer Science project.

Players can aim, adjust shot power, and strike balls on a virtual pool table, with real-time updates ensuring both players see the same table state simultaneously.

Key Features

1. Game Modes

   • Single-Player Practice Mode – Player vs. AI.

   • Multiplayer Mode – Real-time Player vs. Player.

   • Tournament Mode – Knockout-style competitions.

2. Gameplay Mechanics

   • Players take turns striking the cue ball.

   • Physics-based ball movement (collision detection, spin, rebounds).

   • Standard 8-ball rules: Player must pot all solids/stripes, then the 8-ball last.

3. Real-Time Multiplayer

   • WebSockets (Node.js + Socket.IO) or Java WebSocket for live updates.

   • Both players see identical pool table states after every move.

   • Chatbox for player interaction.

4. Cue Stick Controls

   • Drag-and-drop or mouse movement to set angle.

   • Power bar to control shot strength.

   • Visual indicator for predicted ball path (optional assist).

5. Scoring & Rules Enforcement

   • Automatic foul detection (e.g., potting cue ball, hitting opponent’s ball first).

   • Scoreboard with live updates.

   • Match history tracking.

6. Graphics & Animations

   • Realistic 2D pool table with textures.

   • Ball collision animations with smooth rolling effects.

   • Sound effects for ball collisions, potting, and victory celebrations.

7. Leaderboard & Player Stats

   • Tracks matches played, won, accuracy, and fouls committed.

   • Global leaderboard for multiplayer rankings.

Technology Stack

• Frontend: HTML, CSS, Bootstrap, JavaScript (Canvas API for 2D rendering).

• Backend:

  • Node.js with Socket.IO for real-time communication.

  • OR Java/PHP with WebSocket or AJAX-based updates.

• Database: MySQL / MongoDB for player profiles, match records, and leaderboards.

How It Works

1. Lobby & Matchmaking

   • Players log in and join a game room.

   • System pairs two players in multiplayer mode.

2. Gameplay Flow

   • Player 1 takes the break shot.

   • Balls are assigned (stripes/solids) based on first successful pot.

   • Players alternate turns until one pots all their balls and the 8-ball.

3. Physics Simulation

   • Ball movement calculated using JavaScript physics.

   • Collisions, angles, and friction determine ball trajectories.

4. End of Game

   • Winner declared (based on rules).

   • Stats updated and leaderboard refreshed.

Enhancements (Optional)

• 3D Version: Use WebGL or Three.js for 3D pool gameplay.

• Mobile Controls: Swipe/tap gestures for shot power and direction.

• Spectator Mode: Allow friends to watch live pool matches.

• Voice Chat: Real-time communication between players.

• Customization: Players can choose cue stick designs, table themes, and ball skins.
