Worked on the SuperTux/supertux repository to improve the stability and visual fidelity of the game’s particle system, focusing on resolving a bug affecting ghost particle vertical wrap-around. Addressed an issue where particles failed to wrap correctly by adjusting the vertical positioning logic to account for each particle’s height, ensuring consistent visual effects across the virtual height boundary. Emphasized maintainability by providing a targeted patch with clear commit messaging and traceability to the related issue. Utilized C++ and applied skills in bug fixing and game development, resulting in more reliable particle behavior and reducing glitches in wrap-around scenarios without introducing new features.
