Gabriel S. Mainiere developed an Agent Health, Invulnerability, and Game Over system for the profpantoja/chonGame repository, focusing on robust game state management. He implemented health-based damage, invulnerability frames, and attack cooldowns within the Java-based core game loop, ensuring that collision detection and damage handling respected these new mechanics. Using Java and JavaFX, Gabriel tuned damage values for balanced gameplay and established a deterministic game-over condition that halts the loop when health reaches zero, preventing unstable states. This work laid a solid foundation for future health-driven progression, enhancing both player experience and the maintainability of the game’s object-oriented architecture.
