var Damage : int = 25;
var Distance : float;
 
function Update ()
{ 
    if (Input.GetButtonDown("Fire1"))
 
       var hit : RaycastHit;
if (Physics.Raycast (transform.position, transform.TransformDirection(Vector3.forward), hit))
       )
        {Distance = hit.distance;
           hit.transform.SendMessage("ApplyDamage", Damage, SendMessageOptions.DontRequireReceiver);
