A simple implementation of world transfer in dragonfly-mc.

This package provides:

• A WorldProvider to manage multiple worlds.
• Helper functions to transfer entities (especially players) across worlds.
• A built-in /multiworld (alias /mw) command with subcommands for teleporting.

import ( "fmt" "log/slog" // Automatically register the command and load all worlds // just by importing the package "github.com/redstonecraftgg/df-multiworld" "github.com/df-mc/dragonfly/server" ) func main() { conf, err := server.DefaultConfig().Config(slog.Default()) if err != nil { panic(err) } srv := conf.New() srv.CloseOnProgramEnd() // Manually register the original world created by the server // using the folder name inside the root path multiworld.Worlds.Worlds["world"] = srv.World() srv.Listen() for p := range srv.Accept() { _ = p } }

If you want to move a player programmatically:

multiworld.TransferPlayer(playerObj, Worlds, "world2", mgl64.Vec3{0, 64, 0})

This will:

• Save the player's entity handle.

• Remove it from the current world.

• Re-add it to the target world.

• Teleport it to the given position.

The package also registers a command automatically:

• /multiworld teleport <world>

• Alias: /mw tp <world>

This will transfer the player to the given world.

Important: make sure the target position is not obstructed (e.g. no solid block), otherwise the player may suffocate.

The default teleport position is: 0, 64, 0

• Simple MapWorldProvider using Go map[string]*world.World.

• TransferPlayer helper with proper entity handling.

• Autocomplete support for world names in chat.

• Only loaded worlds can be teleported to.

• If you want custom spawn locations, you can extend TransferPlayer with your own logic.

• Currently designed for player transfers, but can be adapted for other entities if possible.
