Worked on the GameDevelopmentKit/GameFoundation repository to enhance extensibility in the SceneDirector component. Focused on refactoring the signalBus member by changing its access modifier from private to protected, enabling derived classes to safely interact with the signalBus while maintaining existing behavior and avoiding API breakage. This architectural adjustment supports safer subclass customization and prepares the codebase for future downstream features. The work was implemented using C# within the Unity engine, drawing on skills in game development and software architecture. No bugs were addressed during this period, with efforts concentrated on delivering this targeted feature improvement over the course of one month.
