🌍 Void's World — MultiWorld Mod

Import and explore multiple worlds as separate dimensions — all within a single Minecraft instance.

Void's World lets server owners import existing Minecraft world saves directly into their running server as live playable dimensions. Players can teleport between worlds instantly using simple commands, with each imported world keeping its own terrain, structures, and spawn point.

No restarts. No separate servers. Just /multiworld import and go.

✨ Features

• Import any world save as a fully playable dimension
• Separate dimension per world — terrain, chunks and POI data from the original world are preserved
• Custom spawn points per imported world
• Per-world settings — PVP, keep inventory, and gamerules configurable per world
• Instant teleportation between worlds with a single command
• Persistent imports — imported worlds are saved to disk and automatically loaded on server restart
• Operator tools — teleport other players between worlds and back to the main world

🚀 Getting Started

1. Place your world folder (must contain level.dat and a region/ folder) inside your server's saves/ directory
2. Join your server and run /multiworld available to see worlds ready to import
3. Run /multiworld import <worldname> to import it as a live dimension
4. Run /multiworld tp <worldname> to teleport into it

That's it. The mod handles copying the world data and creating the dimension automatically.

📋 Commands

All commands are under /multiworld. Permission level 2 (operator) is required for management commands. Teleporting yourself only requires being a player.

📁 How It Works

When you import a world, the mod:

1. Reads the world's level.dat for metadata (seed, spawn, settings)
2. Copies region/, poi/, and entities/ into your main world's dimensions/multiworld/<worldname>/ folder
3. Injects a live ServerLevel into the running server
4. Registers the dimension so players can teleport into it immediately

Imported worlds are saved to multiworld_config/imported_worlds.json and automatically reloaded on every server start.

⚙️ Requirements

• Minecraft 1.20.1
• Forge 47.4.x
• Server-side only — no client mod required

⚠️ Notes

• Imported worlds must be 1.18+ format (subchunk-based, 384 block height)
• The world folder must contain at least level.dat and a region/ folder to be importable
• Removing a world from imports does not delete its copied data from the dimensions folder
• This mod is intended for server use — singleplayer support is not guaranteed
