Contributed to the libgdx/libgdx repository by implementing support for WORLD_1 and WORLD_2 key inputs in the LWJGL3 backend, enabling games to recognize these additional keys. This work involved mapping GLFW key codes for WORLD_1 and WORLD_2 to the corresponding Input.Keys constants within the backend, ensuring seamless integration with existing input handling. The feature was developed using Java and focused on backend development for game applications. The approach preserved the current input pipeline while extending its capabilities, allowing developers to utilize a broader range of keyboard inputs in their games without disrupting established workflows or compatibility.
