PLAYER EQUIPMENT CHANGED

This event is fired when the players gear changes. PLAYER_EQUIPMENT_CHANGED: equipmentSlot, hasCurrent

• equipmentSlot: - InventorySlotId
• hasCurrent: - True when a slot becomes empty, false when filled.

• The second payload value was historically documented doing the reverse; true (1) when filled or false (nil) otherwise.
• Modern FrameXML code labels the payload hasCurrent but does not actually use this payload, so the developer intent is unclear.
• It is unknown if the return values in fact 'flipped' at some point, or if the early documentation was simply wrong.
