looping an animation with a pause inbetween

Unity Engine
1

when i run this script on my model the animation plays in a looping mode,
but it doesn’t stop 8 seconds in between. Anyhow to make this works?

function Update ()
 {
randomanimation ();
 
}


function randomanimation ()
{
animation.Play("punch");
yield new WaitForSeconds (8.0);

}

Even though the function randomanimation() is waiting, Update() isn’t, likewise, it is still getting called every frame.

Try this:

function Start()
{
randomanimation();
}
function randomanimation () 
{ 
animation.Play("punch"); 
Invoke("randomanimation",8);
}
