Prevent walking in the air

when my character is falling, I want to prevent it from walking (or playing any animations) in the air

But I don't know how because there is only 'on collision with another object'.

How can I detect if my character is 'not on collision with another object'??

I think you should try to do it differently.

Say, on key pressed 'Right' -> play 'Walk' animation.

There's got to be an event before everything.

So, on key pressed 'Space' -> play 'Fly' animation.

If 'Player' is on collision with 'Ground' -> Stop 'Fly' animation.

That sorta thing. I'm not sure what you're making, but it helps to be creative and reading tutorials helps with that :P
