BlzdBackpacks

A lightweight, persistent virtual backpack plugin for Paper and Purpur.

Item Restrictions

Item restrictions control what can be stored in the backpack.

They do not prevent players from picking up or carrying those items in their normal inventory.

Both Minecraft Materials and Tags are supported, with configurable blacklist and whitelist modes.

Storage Safety

Every backpack maintains 54 internal slots regardless of the player's currently visible backpack size.

If a player loses a backpack permission, items stored in newly hidden slots remain safely stored and become accessible again if the player regains the required permission.

Requirements

• Java 21
• Paper or Purpur
• Minecraft/Paper target: 26.1.2

RoseStacker is optional.

Commands

/bp — Open your backpack.

/bp toggle — Toggle between Inventory First and Backpack First pickup modes.

Permissions

• blzdbp.small
• blzdbp.medium
• blzdbp.large

The highest permission determines the player's visible backpack size.
