Solved Unique ItemStack Identification

  1. Hello,

    I'm currently working in a way to store persistent data on ItemStacks. I've managed to make it work, BUT as soon as the durability of the ItemStack changes, the data get's lost. So I can't store the data on weapons and / or armors.

    So I was wondering if you guys know any way how to identify ItemStacks, even though they change durability and stuff. Right now I use the item's hashcode to identify them from each other, but as soon as the item takes damage, the hashcode changes too - making it a different item and my data is no longer connected to that item.

    I'd appreciate any help.

    best regards,

    @Lionhard Did you try to put an UUID in the lore?

  3. @timtower I do not need to track who that item belongs to, rather just track which item is which :D for example I have a sword and I save another ItemStack into that ItemStack. Whatever the user does with the item (put it into a chest, drop it, pick it up) I need that this data I saved into it will persist. To do that, I need some way to uniquelly identify this itemstack no matter what.

    I already managed to keep track of each itemStack with custom data inside it, but this works only as long as the itemstack doesn't get damaged, because when it does, the HashCode of it changes - which fools my code and I no longer am able to find that item. So my data remains connected with the old HashCode, which can be any other item now (or none).

    Again, did you try putting AN UUID in the lore? UUID are just identifiers, there not just for players. Generate a UUID for each item. When you need to figure out which item it is, look at the UUID.
