CubWorlds – Lightweight World Management

CubWorlds
A modern, lightweight world management plugin. Designed as a streamlined alternative to heavier systems, CubWorlds gives you full control over custom worlds with minimal setup and great performance.

Wiki: Soon
Discord: https://discord.gg/Hqq3CdnenN

Key Features
Load any number of worlds at server startup via config.yml
Hot-load and unload worlds at runtime with /cubworlds load and /cubworlds unload
Create new worlds with different types: NORMAL, VOID, NETHER, END
Safely delete worlds with /cubworlds delete (includes player relocation + folder cleanup)

Teleportation & Spawn Control
Teleport to any loaded world with /cubworlds tp <world>
Set custom spawn points per world using spawn: "x,y,z,yaw,pitch"

World Access Control
Define permissions required to enter worlds (e.g. liteworld.access.adventure)
Players without access are automatically teleported to a fallback world
Fallback world is configurable (defaults to "world")

️Grief Prevention

prevent-grief: true # it disables block breaking, placing, and interaction in that world

Command System
All commands are handled via /cubworlds:
Commands Description Permission Group
/cubworlds create <name> <type> Create a new world
/cubworlds tp <world> Teleport to a world
/cubworlds list View all worlds and their status
/cubworlds load <world> Load a world from config
/cubworlds unload <world> Unload a world from memory
/cubworlds delete <world> Unload and delete world folder

Lightweight, Modular Design
Works great out of the box.
(Soon) CublexCore support for multilingual messages

Example config.yml

fallback-world: world
worlds:
  - name: lobby
    type: VOID
    prevent-grief: true
    permission: cubworlds.access.lobby
    spawn: "0.5,64,0.5,0,0"
