Is there a way to have multiple backpacks like one for swords and one for potions and the other for magic to keep it separated without having them all in one backpack and saving each of them when a player leaves/joins the game? Cause I got a Backpack GUI with three tabs for them.
You need to code your backpack GUI so that it only shows one tab at a time, then make 3 folders, one for each tab, in the backpack, wire that up to your backpack gui with some functions and you should be fine.
