Space Invaders

Classic Space Invaders game built in Java with clean code architecture, implementing multiple design patterns including Factory, Chain of Responsibility, and Singleton.

Design Patterns

• Factory Pattern - Clean object creation through BlockFactory
• Chain of Responsibility - Two chains handling collisions and events separately
• Singleton Pattern - Manages game state and instance control
• Open/Closed Principle - Add new features without breaking existing code
• Single Responsibility - Each class has one clear job

The collision detection uses bounding box algorithms, and the whole thing follows proper OOP principles. Check manifest.txt for the full technical breakdown of each class and pattern implementation.

Architecture

Organised into focused packages:

game/           # Core game logic and objects
handlers/       # Input and collision processing
factory/        # Object creation
collisions/     # Detection utilities  
events/         # Game event system
rendering/      # Display components
