Minecraft Bedrock Experimental Toggles Explained: When to Turn Them On
Scroll down in any Bedrock world's settings and you will find a section called Experiments. Some addon pages say "turn on Beta APIs" or "enable experimental features" and leave it at that. This post explains what those switches really are, so you can decide whether an addon is worth it.
What experiments are
Experiments are features Mojang is still building. They are shipped inside the normal game so creators and players can try them early, but they are switched off by default because they can change, break or disappear between updates.
The exact list changes with almost every release, but the ones addon players run into most are:
- Beta APIs: unlocks scripting features that are not finalized yet. Script-heavy addons that use brand-new functions need this.
- Upcoming creator features: early versions of new block, item and entity features for creators.
- Gameplay previews: upcoming mobs, blocks or mechanics that Mojang is testing before a full release.
What turning them on costs you
Achievements are disabled
Once experiments are enabled in a world, that world can no longer earn achievements. This is permanent for that world.
You cannot turn them off later
Experiments are locked in once the world is created or saved with them. You can copy the world, but the copy is also experimental.
Updates can break things
Because the features are unfinished, a Minecraft update can change how they work. An addon that relies on them might stop working until its creator updates it, and in rare cases content made with an old experiment can vanish from a world.
When it is worth it
- You are building a new, separate world just to play with a specific addon.
- You are playing on a test copy of your main world.
- The addon does something you genuinely cannot get without it.
When to skip it
- Your long-term survival world, especially one with achievements you care about.
- A shared Realm where other players did not agree to the risk.
- If an achievement-friendly version of the same idea exists.
Most FleetMc Studio addons are built on stable features only, so they work without any experiments. If one of our projects ever needs a toggle, it is mentioned in the project description.
How to enable experiments safely
- Back up the world first (export it as a .mcworld file).
- Open the world's settings, scroll to Experiments, and turn on only the toggles the addon asks for.
- Read the warning Minecraft shows and confirm.
- Activate the addon's behavior and resource packs, then load the world.
If something looks wrong after an update, restore your backup rather than trying to repair the world by hand.
