As of Bedrock v1.19.10 a new /execute command is now available through the Additional Creator Features experimental toggle. Just like when Java edition first got this new syntax back in the Aquatic Update, it caused some trouble, because it introduces some new concepts and changes the way you should be using /execute.
This guide aims to explain these concepts to you, allowing you to easily adapt to the changes and use them to their fullest potential. Readers are expected to have some basic knowledge of the old /execute syntax.
DISCLAIMER: The new
/executesyntax is currently an experimental feature and will likely be expanded in future updates. This guide on the other hand might not. This guide was last updated at 15/08/2022.
