Worked on the SigmaRebase repository to improve the stability and reliability of scaffolding mechanics in a client-side modding context. Focused on correcting block placement timing by refactoring the BlockFlyNCPMode and BlockFlySmoothMode modules, ensuring that placement actions align with player movement events during the pre-update phase. This targeted bug fix addressed timing-related issues with scaffolding and item switching, directly improving the building experience for users. The work involved in-depth analysis of movement-event handling and placement logic, utilizing Java and game development skills to resolve edge cases identified during initial scaffolding tests and to enhance overall user experience in the modded environment.
