Stopping avatar from Flying


Is there a function thats not a zone that stops the user from flying?

Trying to think of a method to improve the hook gun, and one would be to instead just stop the user from flying.
Right now I have a simple “apply thrust” if hook gun is not active, but this is not ideal if you have two of them. So instead, Id would just want to disable the avatar’s auto-fly when above a surface.
