Worked on enhancing controller compatibility in the godotengine/godot repository by delivering SDL3 compatibility improvements for the JoyButton API. Focused on extending the JoyButton enum with new constants and mappings, the developer implemented MISC2-MISC6 support and increased SDL_MAX to accommodate these additions. GDScript bindings were introduced for the new buttons, and API documentation was updated in XML to ensure clarity for other developers. Using C++ and XML, the work reduced runtime warnings related to unrecognized controller inputs and provided a clearer, more robust API for game developers working with input devices in Godot, reflecting a focused and thorough engineering approach.
