🎒 Backpacks

More room. More adventure.

Bring extra storage wherever you go. Backpacks adds personal, command-issued backpacks to your Paper server—with adjustable sizes, automatic saving, and configurable protection on death.

No client mods. Just install, give, and go.

🖱️ Grab it. Open it. Pack it.

Hold a backpack in your main hand and right-click, or use /bp open.

Right-click	Move one item

Put away any item on your cursor before opening. Dragging and hotbar swaps are disabled inside the backpack GUI.

Backpacks, bundles, and shulker boxes cannot be stored inside backpacks.

⚙️ Make it fit your server

After the first successful startup, edit:

plugins/Backpacks/config.yml

default-rows: 3
minimum-rows: 1
maximum-rows: 6
maximum-per-command: 16

keep-on-death: true
owner-only: true
block-creative: true

blocked-materials: []
message-cooldown-seconds: 5

Storage sizes

Set the default size and allowed row range for newly issued backpacks. Changing these limits never shrinks existing bags or erases their items.

Death protection

With keep-on-death: true, players retain their backpacks after dying. Set it to false for normal item drops.

The world’s keepInventory gamerule still takes priority when enabled.

Sharing and ownership

With owner-only: true, only the owner and players with the bypass permission can open a backpack.

Set it to false to let anyone holding the backpack use it—useful for sharing or trading!

Appearance

Customize item.material, item.name, item.lore, and inventory-title.

Use & color codes and these placeholders:

• {owner} — backpack owner
• {rows} — storage rows
• {slots} — total slots

Item appearance changes apply to newly issued backpacks.

Restrictions and messages

• block-creative — prevent opening backpacks in creative mode.
• blocked-materials — add item types that players cannot deposit.
• maximum-per-command — limit how many backpacks a give command can issue.
• message-cooldown-seconds — control how often help messages appear.
• message-prefix / messages — customize the chat text.

The built-in restriction on backpacks, bundles, and shulker boxes always applies.

Apply valid changes with /bp reload.

💾 Saved for your next adventure

Each successful transfer is saved immediately. Interrupted transfers have recovery records, and copies of a backpack item reference the same stored inventory rather than duplicating its contents.

Back up the whole Backpacks folder together with player/world data, including secret.key. Safeguards reduce duplication risks, but cannot guarantee protection against every exploit or interaction with other plugins.

🚀 Getting started

1. Put the jar in your server’s plugins folder.
2. Restart the server.
3. Run /bp give YourName 6.
4. Hold your backpack and right-click!
