Is there any ifNot.Grounded command?

Hey, I’m creating simple game, and i want to make my character use “jump” animation while is not grounded. I know how is.Grounded work in script, but i wonder if does like opposite of this exist? I hope you’ll understand my question C: and thanks for help!

Well the opposite of

if(controller.isGrounded)

is

if(!controller.isGrounded)

or am I missing something?
