Tutorial:Adding a new dimension

This tutorial explains how to add a new custom dimension to a world using a data pack. It assumes you already know how to create a data pack.

Adding a new dimension is as simple as creating one file in the data pack. This first dimension adds a new superflat world using the flat chunk generator.

When adding to an existing world, make sure to leave and reopen the world! A warning screen will ask you to confirm using experimental world settings. It means that new versions can break existing world generation data packs without warning. You can click "I know what I'm doing!".
