Worked on stabilizing the ExcaliburJS/Excalibur repository by addressing a bug in the Scene Crossfade example, focusing on correcting the goToScene method usage to ensure proper scene transitions. This involved updating TypeScript example code so that it compiles and runs as intended, providing a reliable demonstration of scene navigation for developers. Complementary documentation improvements were made to clarify the correct usage within the scene-crossfade.ts example, reducing onboarding friction and potential confusion. The work emphasized clear communication and maintainability, leveraging skills in documentation and example code updates to enhance the reliability and clarity of core Excalibur demonstrations for the developer community.
