Chess Game

This Java-based chess game implementation represents a sophisticated demonstration of object-oriented programming principles and game development concepts. The project utilizes a custom graphics library (StdDraw) for rendering and implements a complete chess game system with turn-based gameplay. The architecture follows a loose Model-View-Controller (MVC) pattern, with the Board class and various piece classes serving as the model, the StdDraw library handling the view, and the GameController class managing the game logic and user interactions.

The GameController class serves as the main orchestrator of the game, managing the game state, handling user input through mouse interactions, and controlling the game flow and win conditions. The board management system uses a coordinate system with (row, column) indexing, implements piece movement validation, maintains the game state and piece positions, and provides methods for piece movement validation, move execution, and board state queries. The input handling system implements a sophisticated mouse input mechanism that prevents continuous click registration through frame-based detection and converts screen coordinates to board coordinates using proportional calculations. The state management system maintains the game state through clear variable management, tracking selected pieces and current player turn, and implementing turn-based gameplay logic.

The implementation demonstrates strong defensive programming practices, including input validation for mouse coordinates, state validation before moves, and error messaging for invalid actions. The code structure is maintainable, with clear separation of concerns, well-documented code sections, and logical organization of game components. The built-in debugging system, with configurable debug output, provides helpful support for development and maintenance.

The architecture provides a solid foundation for future enhancements, including network play support through the addition of a client-server architecture, AI implementation leveraging the existing move validation system for AI decision-making, and save/load features extending the current file I/O system for game state saving and replay functionality. This implementation showcases solid software engineering principles while maintaining clean, maintainable code. It serves as an excellent example of game development in Java, demonstrating both OOP concepts and practical game development patterns. The project's architecture, technical features, and code quality make it a valuable addition to any developer's portfolio, highlighting skills in game development, object-oriented programming, and software engineering best practices.
