Draw out Line in C#

I have a grappling hook and that when you press the button, a line is made connecting you to your target. The problem is that it appears immediately and doesn't draw out towards the target. I was using this video as a reference on how to do it. https://www.youtube.com/watch?v=Bqcu94VuVOI

 private float dist;

 public LineRenderer line;

 private Transform destination;

 public float lineDrawSpeed = 6f;

 private float counter;

  void Update()
     {
        
        
 
 
         var device = SteamVR_Controller.Input((int)controller.index);
         if (device.GetTouchDown(SteamVR_Controller.ButtonMask.Trigger) && energy == true)
         {
             RaycastHit hit;
             if (Physics.Raycast(controller.transform.position, controller.transform.forward, out hit, raycastDistance))
             {
                  
                 counter += .1f / lineDrawSpeed;
                 dist = Vector3.Distance(Object.transform.position, hit.transform.position);
 
                 float x = Mathf.Lerp(0, dist, counter);
 
                 Vector3 pointA = Object.transform.position;
                 Vector3 pointB = hit.transform.position;
 
                 Vector3 pointAlongLine = x * Vector3.Normalize(pointB = pointA) + pointA;
 
                 line.enabled = true;
 
                 line.SetPosition(0, Object.transform.position);
 
                 target = hit.point;
 
                 pointAlongLine = target;
 
                 line.SetPosition(1, target);
 
                
 
                 
 
                 hitwall = true;
 
                 line.material.mainTextureOffset = Vector2.zero;
             }
          
         }
         else if (device.GetTouch(SteamVR_Controller.ButtonMask.Trigger) && line.enabled)
         {
             line.SetPosition(0, Object.transform.position);
 
             line.material.mainTextureOffset = new Vector2(line.material.mainTextureOffset.x + Random.Range(-.01f, 0.05f), 0f);
 
             pressed = true;
 
             hitwall = true;
         }
         else
         {
             line.enabled = false;
             hitwall = false;
           
           
         }
