Worked on the godotengine/godot repository to improve API clarity within XRController3D and animation/XR systems by standardizing signal parameter naming. Replaced generic parameter names with descriptive terms such as action_name and anim_name, which enhanced cross-system consistency and simplified both onboarding and future maintenance for developers. The approach involved careful cross-component refactoring and thorough documentation of changes for traceability. Utilized C++ programming and XML documentation skills, with a focus on game development and signal handling. No major bugs were addressed during this period, but the work contributed to a clearer API surface and reduced maintenance overhead for XR features.
