Andrea Galb worked on refining combat mechanics in the MegaMek/megamek repository, focusing on the PunchAttackAction feature. Using Java and object-oriented programming, Andrea improved the to-hit calculation by ensuring the system accurately accounts for a missing hand actuator, which previously led to miscalculations during melee combat. The technical approach involved defining a hasHandActuator method to resolve a compile-time issue, thereby stabilizing both gameplay logic and build processes. While the work was limited to a single feature over one month, it addressed a nuanced aspect of combat mechanics and laid groundwork for future enhancements in game development and code reliability.
