Plugin to save your items in a personal inventory when you no longer have space. This can be used with certain permissions, both for administrators and for default users. The items will be saved when the player leaves and when the server closes, so we won't have problems when transferring backpacks from one server to another.
Commands:
BOTH: /bp /bp reload /bp clear
PLAYER: /backpack
Permissions: backpacks.usage backpacks.admin
Soon:This was my first achievement of making backpacks, I used tools that I use daily (HashMap, Set, ecc) but not in the way that the idea asked me to do. So the next update will be an item on join and this obviously can be decided from the config file if you get it on join or not.
