About this project
What does Q Backpack add?
Q Backpack
Q Backpack is a lightweight, standalone backpack mod for Minecraft 1.20.1 Forge. It adds four upgradeable backpacks that are equipped in the Curios back slot and displayed directly inside the normal player inventory screen.
The Leather Backpack provides 9 storage slots. The Iron Backpack provides 18 slots. The Gold Backpack provides 27 slots. The Diamond Backpack provides 36 slots.
When the player's inventory is full, picked-up items will automatically be placed into the equipped backpack if space is available.
The integrated inventory screen includes a Quark-style sorting button that sorts both the player's main inventory and the backpack. The tooltip shown when hovering over this button can be disabled in the client configuration file.
Backpacks containing items cannot be unequipped. Backpack nesting is also prevented.
Each backpack tier has its own item texture and wearable model. All four tiers have upgrade recipes, beginning with leather and a chest and progressing through iron, gold, and diamond.
