Worked on the godotengine/godot repository to address a usability issue in the animation editing workflow, focusing on the validation of drag ranges for animation keys and markers in FPS mode. Implemented a fix in C++ that ensures both drag and spinner controls for time properties do not exceed the total animation length, thereby preventing overruns and reducing editing errors. This adjustment improved the reliability of the animation system’s UI controls, supporting smoother iteration for contributors and users. The work demonstrated attention to detail in UI design and game development, contributing to higher quality animation tooling within the project.
