Worked on the CCBlueX/LiquidBounce repository to enhance Minecraft client input handling by refactoring the MixinMouseHandler component. The approach involved replacing the deprecated WrapWithCondition injector with the more robust WrapOperation, using Java and Mixin technologies to improve compatibility and maintain behavioral consistency. This update modernized the input pipeline, aligning the implementation with MixinExtras standards and project conventions while preserving existing mouse rotation logic. The work focused on reducing technical debt and establishing a foundation for future input-control improvements. No bugs were fixed during this period, but the feature delivered increased maintainability and robustness for Minecraft modding workflows.
