Lerpz 3D platform tutorial - Laser Solution

Here's my crude butchery of a solution, in lasertrap.js Uses same sound as getting hit by robotguards which isn't ideal, because it's using the existing 'Slam'. It works for me using unity 3.4. Edit: and 3.5

 function Update ()
 {
     var offset = (1 + Mathf.Sin(Time.time * speed + timingOffset)) * height / 2;
     transform.position = originalPosition + Vector3(0, offset, 0);
     
 
 
     if (Time.time > lastHitTime + 0.25 && Physics.Raycast(transform.position, transform.forward, hit, laserWidth))
     {
         if (hit.collider.tag == "Player" || hit.collider.tag == "Enemy")
         {
             Instantiate(hitEffect, hit.point, Quaternion.identity);
             hit.collider.SendMessage("ApplyDamage", damage, SendMessageOptions.DontRequireReceiver);
             lastHitTime = Time.time;
 
         //activate slam on 3rdpersoncontroller to knock player back
         var slamDirection = transform.InverseTransformDirection(target.position - transform.position);
             slamDirection.y = 0;
             slamDirection.z = 0.1;
             if (slamDirection.x >= 0)
                 slamDirection.x = 0;
             else
                 slamDirection.x = 0;
             target.SendMessage("Slam", transform.TransformDirection(slamDirection));
         }
     }
