You can enable flying for players through island settings, team settings, and class settings. The most common way to do it for select players is through class (using a Class Designer and Class Selector).
I used 5 devices:
Mutator, 2 Class Selectors and 2 Class Designers.
In the Class Designers I have 2 classes: one can fly and the other can’t.
In the first Class Selector I set change player to class on mutator zone → enter.
In the second Class Selector I set change player to class on mutator zone → exit.
It can also work with multiple mutators.
However, I’m frustrated because I wanted to do this in Verse, but didn’t find a way.
As mentioned in my first post we have the method IsFlying in the fort_character. But no way to Set IsFlying.
