Clone a world

To clone a world you can use the /world clone <world> command.
This command creates a copy of the specified world, allowing you to work on a separate instance without affecting the original.
There are three options: name, key, and full.
If you don't specify any of these options, the cloned world will have an auto generated name and key, and the world data will be copied 1:1.

The full option defines whether the cloned world should be regenerated or an exact copy of the original world.

Example on how to create an exact copy of a world:

/world clone worlds:my_world

Example on how to clone a world's generation settings (no world data, scoreboards, player data, etc.):

/world clone worlds:my_world full false

You can define the name and key of a cloned world by using the name and key options:

/world clone worlds:my_world name "my world copy" key my_world_copy
