What is the "jump"/ Y axis? How It's called in scripting?

Hey, I’m a bit new in Unity and i really need help with something.
I’m creating a simple game and i want to play an animation while I’m in air.
It worked with Walking

    		if(Input.GetAxis("Vertical"))
    		{
    		animation["Run"].wrapMode = WrapMode.Loop;
    		AnimPlayer.animation.CrossFade("Run", 0.4);
    		}
    		else
    		{
    		animation["Idle"].wrapMode = WrapMode.Loop;
    		AnimPlayer.animation.CrossFade("Idle", 0.4);
    		}

^ That worked perfectly, but i need to know what Axis is for Y :frowning:

I only found someone said about if(Input.GetAxis(“Jump”)) but that doesn’t work :<
Sorry for my bad english!

Well you need to define what controller/button is what axis. Or you could just hardcode in the buttons.

 if(Input.GetKey(KeyCode.Space))
