Pacman - Classic Arcade Clone

Overview

Developed a complete clone of the classic Pac-Man arcade game from scratch using Processing and Java. Structured the project with a clean, modular Object-Oriented architecture, separating entities like Hero and Ghosts from the core game loop and rendering logic. Implemented an intelligent ghost AI using algorithmic pathfinding (A* / BFS) to provide challenging and dynamic gameplay. Created a custom text-based level parsing system that seamlessly reads and renders complex mazes from simple .txt files, enabling easy map creation and multi-level progression. Built a robust state management system to handle smooth transitions between the main menu, active gameplay, and game over screens. Engineered a comprehensive save/load system using File I/O to persist game progress and maintain a continuous high score leaderboard across different play sessions. Handled precise grid-based movement and collision detection to emulate the authentic arcade feel.

Key Features

• Intelligent Ghost AI & Pathfinding
• Custom Text-Based Level Parsing
• Multi-level Progression System
• Save & Load Game Progress
• Persistent High Scores Tracking
• Dynamic Game Menu & UI
• Grid-based Movement & Collision Detection
• Modular Entity Management (Hero, Ghosts)

Technical Challenges

• Implementing efficient and bug-free pathfinding algorithms for multiple ghosts to dynamically chase the hero simultaneously.
• Designing a robust level parser capable of accurately translating text file character grids into solid walls, paths, and collectable dots.
• Managing complex game state transitions between the start menu, gameplay loop, pausing, and the game over sequence.
• Handling precise grid alignment and fluid entity movement to ensure the hero and ghosts don't overlap or sequence break through walls.
• Reading and writing persistent data cleanly without performance drops to handle the saveed states and high score logs.
