Server Backpacks! 1.4-alpha+1.21.8

by Rouesvm on Jul 20, 2025
Download

Currently released as an alpha for testing. Not recommended for use on a server, but it's stable enough.

Changelog

Features

  • Includes a module system for backpacks. Available modules:
    • Void Module - Voids nearby items matching a specified filter.
    • Vacuum Module - Automatically inserts nearby filtered items into the backpack.
    • Crafting Module - Opens a crafting menu. (Shift + right-click the backpack when in its inventory, then right-click the Crafting Module.)

  • Some configuration entries were removed in this alpha:
    • enable_globalpack
    • enable_enderpack

  • These has been replaced with:
    • disabled_backpacks: [] - Specify a backpack's ID to disable, e.g. , ["global", "ender"]

  • Added new configuration entries:
    • "enable_upgrades": true
    • "disabled_upgrades": [] - Specify a module's ID to disable, e.g. , ["void_upgrade", "magnet_upgrade"]

Notes

  • Applying a filter - Surround the module with an item (used as the filter) in a crafting table. (You cannot add or remove an item from a module's filter, you can only replace it.)
  • Applying a module - Place a module and a backpack into a smithing table to apply the module.
