Can not get my raycast to detect an object

So I have a raycast script attached to an empty game object I can see the Debug.DrawRay but when my player walks into it the debug.log does nothing here is my code:

 function Update ()
 {
    
     Debug.DrawRay (transform.position, Vector3.forward * 10, Color.green);
     var hit : RaycastHit;
     if ( Physics.Raycast( transform.position, transform.forward, hit, 100.0 ) )
     {    
       
         if (hit.collider.tag == "Player")
         {
             Debug.Log("HIT!!!");
         }
         
     }
 
 
 }
