Backpack
A virtual backpack you can upgrade and open anywhere!. Free Minecraft Java mod for 1.10, 1.11, 1.12.
⬇ Download on Spigot
This plugin allows a user to open up a virtual backpack anywhere they are in Minecraft by using /backpack
The backpack can be upgraded by items that you define in the config file (i.e. 64 pieces of Obsidian or 10 diamonds) Each upgrade provides the virtual inventory with an extra 9 slots, with a max of 54 slots (size of a double chest) With the 1.2 update, you can now use your economy for backpack upgrades, this requires Vault!
As of the 1.3 update, when upgrading the backpack via economy there is now the option for editing the multiplier per tier level and also the base price in which backpacks get upgraded by.
The upgrade-lock allows you to specify how many times you would like a player to upgrade their backpack. (1-5 times)
Formula used to calculate the slots
upgradeLimit = (tier-upgrade-limit * 9) + 9
This will allow the player to upgrade from 9 slots to 36 slots (4 rows)
tier-upgrade-limit: 3
You now have the option in the config to specify whether or not you want the contents of the players virtual backpack to be dropped when they die!
All inventory data is saved in player.yml files under:
plugins/backpack/inventories
