Basic Question: the Not behaivor

If I want to check if an actor has lift a region, does using the
"If actor is Not: (actor of type is inside region)" Do that?

Basically I want to know if the "not" block reverses everything..

You can use any of these 2 blocks to check when an actor is no longer inside a region:

Ahh okay. I figured not would work as well but I guess not:(

They should both work equally, however the wrapper (the first block) will only get executed once, whereas the second block can be used in an Always event to run some code multiple times.
