Installation
Requirements
WorldEdit: Bedrock Edition is an addon that's compatible with Minecraft's latest release version. You can also install this addon on server hosting sites such as Aternos. It can be used in both singleplayer and multiplayer games.
Note
This addon will not work on Minecraft: Java Edition.
Installation Step-by-Step
Locally
Once you've downloaded the addon, simply open it with Minecraft to get it imported. Mobile users may need a file explorer that allows opening the addon with Minecraft. CX File Explorer and Documents are recommended for Android and iOS respectively.
If you have the same, or later version of the addon already imported, you may need to delete both the behaviour and resource pack in Settings > Storage. In a new world, or an already existing one, add "WorldEdit" in Behaviour Packs and "WorldEdit [RES]" in Resource Packs. Also enable "Beta APIs" in Experimental Features. Create/Enter the world, and you're ready to use WorldEdit!
If you have a console, and either a PC or mobile device, use a realm to transfer a world from one platform to the other.
Servers
There is a separate version of WorldEdit made for dedicated servers (not to be confused with Realms). This version comes as a zip. You must install it depending on how your server is hosted.
This version also comes with a file called variables.json which you must put in the server's config/default folder.
Warning
If you are using Aternos, use the normal addon, as it doesn't seem to support variables.json at the time of writing.
Uninstalling from a world
Uninstalling is as easy as deactivating the addon in the world. If you want to remove it from your game installation entirely, go to Settings > Storage and delete it from there.
