2d Animated sprite sheets problem, help please! :b

Hey guys, can someone tell me how to draw sprite animated sheets? Whenever i try to do it, i put this script:


#pragma strict

var Player : GameObject;
var spawnPoint : Transform;


function OnTriggerEnter(other : Collider){
if(other.tag == "Player"){
Destroy(other.gameObject);
var P : GameObject = Instantiate(Player, spawnPoint.position, Quaternion.identity);
var sf = Camera.main.GetComponent(SmoothFollow2); // sf - smooth folow
sf.target = P.transform;
} else {
Destroy(other.gameObject);
}
}

But unfortuneately my character is shaking whenever im standing still. Can someone plz tell me whats the problem?
