ImmutableWorld Command Guide
The /immutableworld command locks down your Minecraft world. It prevents players from placing or breaking blocks unless they have World Builder status. This is super useful if you’re running a server or classroom world and want to control who can actually build.
What Does Immutable World Actually Do?
An immutable world means the world can’t be changed. Sounds simple, but there’s more to it than that. Minecraft Education Edition has two separate settings that work together:
- World Builder status – This is a player setting. When it’s on, that player can place and break blocks. When it’s off, they can’t (unless immutableworld is off too).
- ImmutableWorld rule – This is a world setting. It determines if players without World Builder status can build.
How These Settings Work Together
Here’s the thing: you need both settings to be true to actually block players from building.
| World Builder Status | ImmutableWorld Rule | Can Place/Break Blocks? |
|---|---|---|
| true | true | Yes |
| true | false | Yes |
| false | true | No |
| false | false | Yes |
TL;DR: Players can only be blocked from building if they have World Builder set to false AND immutableworld is true.
Before You Start
You need cheats enabled in your world to run commands. Make sure that’s turned on first.
