Worked on the TeamTwilight/twilightforest repository to address a core gameplay issue involving item attribute modifiers. Focused on correcting the alignment of attribute modifiers for the GiantPickItem when held in the MAINHAND slot, ensuring that block and entity interaction ranges now properly reflect intended game mechanics. The solution involved updating the attribute modifier logic to use EquipmentSlotGroup.MAINHAND, directly resolving a bug that previously caused inconsistencies in item behavior. This work required a strong understanding of Java development and game development principles, particularly in managing attribute modifiers to maintain consistency and correctness within the mod’s gameplay systems and user experience.
