Blink, Dash, Raycasting

So, i am creating a Dash script, but no one has proper help anywhere that i can find, its an fps, and wherever you look and if you press fire1 (mouse leftclick) you telleport (dash) lets say 10 units ahead. But, my problem is that im not even telleporting in-game, and i really dont know what i SHOULD be doing.

     public Transform cam;
     public RaycastHit hit;
     public Transform character;
     public float range = 10;
     private Transform ray;
     
 
     // Update is called once per frame
     void FixedUpdate () {
         Vector3 origin = transform.position;
         Vector3 direction = cam.transform.forward;
         Physics.Raycast (origin, direction, range);
         if (Input.GetButtonDown("Fire1")) {
 
             origin += direction * range;
 
         }
     }
 }
