Daniel Liu developed a first-person camera system with mouse-based control for the PurdueSIGGD/SIGGD-GAME-2025 repository, focusing on enhancing player immersion and interaction within the Unity game environment. Using C# scripting, Daniel implemented real-time input handling to ensure smooth and responsive camera movement, laying a robust foundation for future gameplay features. The work emphasized stability and incremental delivery through Git, with attention to preparing the system for quality assurance feedback. Although no major bugs were addressed during this period, Daniel’s contribution provided a core gameplay mechanic that supports further camera refinements and demonstrates proficiency in both Unity and C# development practices.
