Multi World

Multi World is a behavior pack that allows you to create and manage an unlimited number of independent "sub-worlds" inside a single Minecraft world. Each sub-world only loads when players are inside it, bringing zero performance cost when empty.

Installation

Import the .mcaddon file.

Activate both the Multi World BP and Multi World RP in your world settings.

Enable the Beta APIs experiment.

Management Menu

The /mw:menu command can ONLY be executed by operators. From this menu, you can:

Create new worlds, list existing ones, toggle them open/closed, rename them, or delete them.

Set a world's spawn point by using "Set Spawn" while inside that specific world.

Mark a world as the "Lobby" — players will automatically teleport there when they first join or when they die.

Toggle a public teleportation item (default name "Menu"), and customize its name and lore/description. When enabled, this item is automatically given to every player; it is kept on death and immediately vanishes if dropped.

Automation via Command Blocks

The /mw:tp <id> <player> [x] [y] [z] command can be used by both operators and command blocks. Each world has a fixed numerical ID (1, 2, 3...). By knowing this ID, you can set up systems—such as when an NPC is clicked or a trigger is activated—that automatically teleport the player to a specific world (and to specific coordinates if desired). If no coordinates are specified, they will be teleported to the world's saved spawn point.
