João Pedro Abreu enhanced the profpantoja/chonGame repository by implementing core gameplay features and improving code maintainability. He developed collision detection with visual feedback, enabling both player-controlled and AI agents to trigger intersection checks and display a clear “COLLISION!” indicator during gameplay. Using Java and object-oriented programming principles, João also authored comprehensive JavaDoc documentation for the Environment class, detailing its fields, constructors, and methods to support future development and onboarding. His work established a robust foundation for future AI interactions and reduced potential debugging time, demonstrating depth in both game development and technical documentation within a short project period.
