Developed a core gameplay feature for the CapstoneTFS_Fall2025 repository, focusing on player health management and ability cooldown systems within Unity using C#. The work introduced a real-time HealthBar UI that displays player health, providing immediate feedback for damage and healing events. Additionally, implemented ButtonCooldown visuals to indicate ability readiness, enhancing player decision-making and reducing confusion during gameplay. The feature was delivered as a cohesive, end-to-end system, with clear traceability through targeted commits. This approach supports easier tuning of health and cooldown parameters for future balancing and quality assurance, demonstrating proficiency in game development, scripting, and UI integration.
