Worked on the Wanderers-Of-The-Rift/wotr-mod repository, focusing on refining quest progression mechanics within a Java-based game development and modding context. Addressed a specific bug by implementing player-only kill objective validation, ensuring that kill progress increments exclusively when the killer is a player rather than a non-player entity. This technical approach closed an exploit where non-player entities could unintentionally advance objectives, thereby improving gameplay balance and the reliability of milestone tracking. The solution involved careful modification of the objective validation logic, resulting in more accurate player metrics and a more stable quest system for ongoing mod development and maintenance.
