Experimental Features in Minecraft: Bedrock Edition

Note

This documentation is segmented into Stable and Experimental document sets. To see full documentation about experimental features and APIs, be sure to select the Minecraft Bedrock Experimental APIs option.

With each retail version of Minecraft: Bedrock Edition, there are a few features that are currently in an experimental state. Experimental Features can be toggled on for creators who are interested in testing the latest features offered in the beta, preview, and retail versions of Minecraft.

Note

The Experiments toggle list is subject to frequent changes and could have entirely different options from the ones in your own version of Minecraft.

Experimental Features available in Minecraft: Bedrock Edition

There are three sets of experimental features available, depending on whether you are using a stable (retail) version of Minecraft, the latest version of Minecraft Preview, or a beta version of Minecraft.

How do I activate an Experimental Features toggle for my world?

You can activate an experimental toggle for any of your new or existing worlds.

Warning

Activating experimental features that are still under development means that your world might crash, break, or not work with future updates.

If you're planning to build content that you want to share with the community, it would be best to do it in a non-experimental world.

Toggle Experimental Features in a New World

If you are building a new world from scratch to test experimental features, you can toggle which features you want enabled in the Game Settings.

1. Under Game settings, navigate down to Experiments and select a toggle to enable the feature.

   

2. When you get the popup asking Activate Experimental Gameplay?, select Activate Experiments.

   

Toggle Experimental Features in an Existing World

If you want to add experimental features to an existing world, open that world's game settings and activate the toggles just like you would for a new world.

Note

A copy of your world will be generated automatically after you activate an experimental feature toggle. You can also manually create copies of your world as an extra precaution, in case something goes wrong.

1. Select the world you want to add experimental features to and select the Edit button.

   

2. Under Game settings, navigate down to Experiments and select a toggle to enable the feature.

   

3. When you get the popup asking Activate Experimental Gameplay?, select Activate Experiments.

   "

After you select Activate Experiments, a copy of your existing world will be created. The copy will have the same name as the original world with "Copy of..." added in front of it.

Verify that the World has Experimental Features Enabled

After you've created a world that has an experimental feature toggle enabled, your world will get a tag next to the game mode in your Worlds list that says Experimental.

Another way to identify if your world is using experimental toggles is to visit the settings for your world. In the Game world settings, scroll down to the Experiments section to see which experiments are enabled.

Important

Worlds that use experimental features cannot be restored to a non-experimental state.
