How do I make my character initiate a falling animation after running off a ledge or being hit off a ledge?

I’m not sure my setup has those functions. Did I mention I’m using Paper 2D? I’m not doing a 3D game I don’t have pawns and that kind of stuff. I’ve tried to locate the stuff you have in the image on my UE4, and nothing is showing up. Thanks for walking me through this, by the way. I really appreciate the help.
