Apr 1, 2025April 2025 focused on stabilizing animation playback in spine-runtimes by delivering a targeted bug fix and upstream port. Implemented a refactor of the animation mixing state to correctly handle cases where animations are not being mixed out, clarifying when a 'from' animation entry finishes and is removed to prevent lingering states and ensure smoother transitions. This work includes porting upstream commit f1e0f0f (#2807) as commit 23233222f9eac67273007925c3cf3b39ccdbdee9. Overall impact: improved runtime stability and visual fidelity, reduced transition glitches, and clearer animation state management. Demonstrated proficiency in C++, refactoring, patch porting, and cross-repo collaboration.
