Contributed to the godotengine/godot repository by enhancing device compatibility and input reliability within the engine. Focused on updating the SDL device blocklist to support a broader range of controllers and devices, thereby improving cross-platform stability. Addressed a regression in input event handling by refining the logic for touch and mouse inputs, ensuring accurate button state management and filtering out emulation device inputs. Utilized C and C++ to implement low-level input event processing and regression debugging, with clear commit traceability. The work demonstrated strengths in bug fixing, device compatibility, and input handling, directly improving user experience and platform robustness.
