    I made the backpack, which is
    • Dyeable through the crafting table.
    • Easily renamable using an anvil.
    • Wearable in your chest slot.
    • Upgradable to get more slots (9 -> 18 -> 26 slots)

    How to Use Backpacks

    • To store or retrieve items, simply drop the backpack on the ground. It will transform into a barrel, allowing you to manage your items. Click the "Exit" button slot to revert it to a backpack item.

    Neat data pack! It's got some strangeness to it, due to how it's implemented that makes it still desirable to get shulker boxes. For example, it doesn't like to be placed on some types of blocks, like slabs.

    Also, I would like to report a bug: Dropping this near villagers can cause them to convert to fishermen because it's technically a barrel.

    You can only get the shulker box after the endgame. This datapack makes up for the gap period

    I'm sorry, it's not a bug, it's a bottleneck of the datapack.

    Hey paul i like your datapack so much i recently used in my new survival world and i love it💖.
    But i remove the large backpack from the files because in my opinion if everybody uses this datapack then no one will wondering to use shulker boxes because
    First of all the crafting recipe is so easier than the shulker box. I remove the large backpack from files because i think then shulker boxes will lose their value 🙃 and i think i did right think because then everyone will try to get in the end for shulker boxes😙 beacuse of its 29 slots. Sorry if i hurt you very very sorry😢.
    Anyway i keep the medium backpack in files for its 18 slots.
    BTW Please update this datapack to 1.20.4!!

    Currently got a weird bug, the backpack worked fine on the surface but now I'm underground mining it won't place. Not even moved it around in my inventory between the two ¯\_(ツ)_/¯

    Thanks for the datapack!



    Everything works fine, except the backpacks use the leather chestplate sprite in my inventory, was the sprite in your desc added in afterwards manually? The GUI in the Working Table also just looks like a barrel's inventory with clay ball place holders.



    None of these are game breaking, but just wondering if this is a simple fix i may be overlooking
