AntiInventories

AntiInventories is a small Paper 1.21.11 add-on for Multiverse-Inventories 5. It lets selected worlds keep the inventory a player already has instead of loading a different Multiverse-Inventories profile.

For example, with AutoMine configured:

Wild_Forest1 -> AutoMine

The player arrives in AutoMine with the exact inventory they had in Wild_Forest1. Login, logout, and optional game-mode profile handling are also bypassed while the player is in a configured world, so reconnecting does not silently replace that inventory.

Requirements

• Paper 1.21.11
• Java 21 or newer
• Multiverse-Core 5
• Multiverse-Inventories 5.3.1 or newer

Build

mvn clean package

The finished plugin is target/AntiInventories-1.1.0.jar.

Install

1. Back up the Multiverse-Inventories data directory.
2. Put AntiInventories-1.1.0.jar in the server's plugins directory.
3. Make sure Multiverse-Core and Multiverse-Inventories are installed.
4. Start the server.
5. Edit plugins/AntiInventories/config.yml, or use the commands below.

Commands

Command	Purpose
/antiinv add <world>	Add a bypass world
/antiinv remove <world>	Remove a bypass world
/antiinv forceremove <world>	Remove the world from every explicit Multiverse-Inventories group and AntiInventories, then reload both plugins
/antiinv list	Show bypass worlds and direction
/antiinv reload	Reload config.yml

The aliases /antiinventories, /antiinv, and /ai are available. Commands require antiinventories.admin, which defaults to server operators.

/antiinv list also shows a clickable Force remove control beside each bypass world. It places the force-removal command in chat for confirmation. If a world belongs to a Multiverse-Inventories group through a wildcard or regular expression, the command stops atomically and reports that pattern instead of changing it and potentially removing other worlds.

Direction setting

bypass-direction controls which crossings are ignored:

• ENTERING: keep the current inventory only when entering a bypass world.
• LEAVING: keep it only when leaving a bypass world.
• EITHER: keep it when either side is a bypass world.

EITHER is the default. Be aware that it intentionally lets a bypass world act as a bridge between otherwise separated inventory groups. Use ENTERING if players should carry items into AutoMine but should load the destination profile when they leave it.

The plugin cancels Multiverse-Inventories' official share-handling event. It does not duplicate, serialize, clear, or restore item stacks itself. Because the whole Multiverse-Inventories transaction is skipped, other profile values such as experience, health, and hunger also remain unchanged on a bypassed crossing.
