Your Items to New Worlds

With this mod you can take items from an old world (or at least a copy of them) with you to a new world. This includes items from your inventory, your ender chest and containers placed in the world, like chests, shulker boxes or chiseled bookshelfs.

You can access the screen during world creation under More->Import Items, or via the importItems command.

You can copy items from worlds from versions 1.20.4 and below. (Until a certain point. Oldest version tested is 1.7.10.) If you want to import modded items from below 1.8 you have to manually add their numeric id to the idMappings.json in the config folder though.
