Expandable Backpacks: Upgradeable Backpacks for Minecraft
Inventory management is a constant struggle in Minecraft, especially during long mining expeditions or large building projects. Expandable Backpacks: Upgradeable Backpacks for Minecraft solves this by introducing a fully customizable backpack system. This is not just a portable chest; it is a modular storage network with upgrade slots, dye options, and fifteen distinct compartments that alter how you play. Even though the original author has stopped active development, the mod remains fully functional for Minecraft versions 1.10 through 1.12.2, and the source code is publicly available on GitHub for community forks.
Getting Started with Your First Backpack
The core crafting component is Obsidian Skin. To make it, combine obsidian, leather, and two strings. Once you have a single piece of Obsidian Skin, pair it with a chest in the crafting grid to produce your first backpack. At this stage, it offers only one inventory slot, but the real potential lies in the upgrade system that follows.
Interface and Controls
To open the backpack, right-click while holding it or press the default key "C". If you hold Shift and hover over the backpack in your inventory, a detailed tooltip appears showing slot count, owner information, and privacy mode. Since version 1.0.2, a dedicated backpack slot exists, freeing your chestplate and hotbar space. Access it by pressing "X" or using the dedicated button in the interface. All keybindings can be remapped or disabled in the configuration file if they interfere with your play style.
Expanding Capacity and Customization
Inside the backpack interface, there is an upgrades tab. The central element is the Obsidian Skin slot. Each unit placed there increases the capacity by one slot, up to a maximum of 54 slots, matching a large chest. In this same tab, you can rename the backpack (up to 32 characters), dye it with any vanilla color, and toggle the privacy mode between public and private.
Pay close attention to the compartment slots. You start with one available. The second slot unlocks after adding 17 Obsidian Skins, and the third opens after 35. These compartments are what transform the backpack from simple storage into a multi-tool.
The Fifteen Compartments Explained
Compartments are removable upgrades that grant unique abilities. Each requires specific resources to craft. Here is a breakdown of the most impactful ones:
- Basic – A crafting component used to create other compartments. Crafted from one Obsidian Skin.
- Soulbound – Keeps the backpack and all contents on death. Requires a Nether Star.
- Pickup – Automatically collects picked-up items into the backpack if a matching item is already stored. Crafted with a hopper.
- Empty – Shift-right-click on any block with an inventory instantly transfers all backpack contents into that block. Requires a cauldron.
- Infinite – Allows placing other backpacks inside this one, creating nested storage. Requires a diamond block.
- Incinerate – Turns the backpack into a trash can, instantly destroying items. Crafted with a lava bucket.
- Armored – Provides 3 armor points when worn on the chest. Requires an iron chestplate.
- Swap – Press "V" to swap your hotbar contents with the first 9 backpack slots. Requires a gold block.
- Guarded – Damages and slows players who try to open someone else's backpack, while alerting the owner.
- Quivered – Arrows are consumed from the backpack when firing a bow, as long as one arrow is in your inventory.
- Ender – Adds an Ender Chest tab. Requires an Ender Chest.
- Sending – Shift-right-click a receiver block to designate a target; all items in the backpack teleport to that block. Works only in the same dimension or if the receiver is in the Overworld.
- Crafting – Adds a crafting table tab. Requires a crafting table.
- Tank – Stores up to 8 buckets of a single fluid type. Right-click a liquid to collect it, Shift-right-click the ground to pour it out.
- Creative – Items are not consumed when extracted. Available only via commands or creative tab.
Privacy and Admin Commands
Every backpack is bound to its owner. Use /backpack addowner <player> to add a co-owner and /backpack removeowner <player> to remove one. The privacy toggle is in the upgrades interface. Operators can run /backpack whohasmybackpack to locate their backpacks held by other players, and /backpack help lists all commands.
