I have this code here:

 private var red_right_left_moved=false;

private var red_left_right_moved=false; private var red_left_right_moved2=false;

private var red_back_front_moved=false;

function Update () {

var screenCenter = new Vector3(0.5F, 0.5F, 0);

var ray = Camera.main.ViewportPointToRay(screenCenter);

var hit : RaycastHit;

//right left 1

if(Input.GetButton("Fire1")&& red_right_left_moved==false){

if (Physics.Raycast (ray, hit, 1000)) {

if(hit.transform.tag=="red_right_left"){

   hit.transform.animation.Play("anim1");

   red_right_left_moved=true;

}

}

}

....etc....
