Just Backpacks: Enhanced

Just Backpacks: Enhanced is a full rewrite and evolution of Just Backpacks V3, built from the ground up with a redesigned storage engine, a new complement system, and deeper vanilla integration. Every item you store is safe — across sessions, restarts, and dimensions.

💾 Persistent Storage

Your items are never lost — the storage system is built around three principles:

While Playing: Your backpack lives as an entity in the world, accessible with zero lag.
Background Saving: When you put the backpack away, its entity is saved as a persistent structure — queue-based to avoid heavy operations.
On Exit: All active backpacks are flushed and saved across the Overworld, Nether, and The End.
Ender Backpack: Acts as a portable Ender Chest — its storage is tied to your player and shared across all your Ender Backpacks, independent from the vanilla Ender Chest.

💎 Backpack Tiers

Start with a basic Backpack and upgrade your way to Netherite — or take a different path with the Ender Backpack.

Tier	Material	Slots	Complement Slots	How to Obtain
1	Backpack	9	1	Crafting Table
2	Copper	18	2	Copper Upgrade Kit
3	Iron	27 (= Chest)	3	Iron Upgrade Kit
4	Golden	36	4	Golden Upgrade Kit
5	Diamond	45	5	Diamond Upgrade Kit
6	Netherite	54 (= Double Chest)	6	Netherite Upgrade Kit
—	Ender	27	—	Ender Chest + Backpack

The basic Backpack is also available in 16 dyed color variants — simply combine it with any dye.

⚙️ Complement System NEW in Enhanced

Every backpack tier has at least one complement slot — passive ability upgrades you install directly into your backpack. The higher the tier, the more complements you can equip simultaneously. The Ender Backpack is the only exception, as it has no complement slots.

Complement	Effect
Torch	Emits dynamic light around you as you explore dark areas — no torch placing required
Magnet	Attracts nearby dropped items directly into your inventory
Food	Automatically feeds you using food stored inside the backpack
XP	Attracts nearby experience orbs toward you automatically
Auto-Sort	Keeps the backpack's contents sorted automatically
Soulbound	The backpack is keep on death — you never lose your items

🔧 Upgrade Kit System

Every tier is reached by upgrading your existing backpack with a material-specific kit. Your items are always preserved — no crafting from scratch, no lost inventory.

📋 How to Upgrade — Step by Step

Craft the Upgrade Kit for your target tier at the Crafting Table.
Place your current backpack in your offhand slot.
Hold the Upgrade Kit in your main hand.
Use / Interact — Right-click on PC · Long-press on mobile.
Done ✔ — your backpack is upgraded and all your items are still inside.

⚠ Note: Each kit only works on its matching tier. You cannot skip tiers.

🐛 Fixed from V3: The backpack no longer gets stuck in your offhand after upgrading — you can freely unequip it at any time.

🎒 How to Use

Equip: Hold the backpack in your main hand.
Open: Interact (Right-click or Long-press) to open the inventory.
Close: Switch to any other item — the backpack stores itself instantly.
Upgrade: Offhand = backpack · Main hand = Upgrade Kit · then Interact.
Dye: Combine a basic Backpack with any dye to change its color.
