Worldborder command

The chunky worldborder command tells Chunky to pregenerate every chunk within the world border. The world is set using the chunky world command.

What does it do?

Under the hood, the chunky worldborder command does two things:

Sets the centre to 0,0 (you can manually set the centre with the chunky center command).
Sets the radius to the same radius as the worldborder.

/chunky worldborder

The command doesn't take any arguments.

To set the diameter of the vanilla world border, you use the /worldborder command:

/worldborder set <diameter>

For example, for a world border of diameter 20,000, use:

/worldborder set 20000
