动画层的应用

function Start ()
{
   animation.wrapMode = WrapMode.Loop;
   animation["jump"].wrapMode = WrapMode.Once;
   animation["jump"].layer = 1;
   animation.Stop();
}

function Update ()
{
   if (Mathf.Abs(Input.GetAxis("Vertical")) > 0.1)
      animation.CrossFade("run");
   else
      animation.CrossFade("walk");

if (Input.GetKeyDown ("space"))
animation.CrossFade("jump");
}
