enable/disable navmesh agent and obstacle same object (player)

its c sharp. my code is as follow:

 void Start () 
 {
     agent = GetComponent<Nav$$anonymous$$eshAgent> ();
     obstacle = GetComponent<Nav$$anonymous$$eshObstacle> ();
 }

 void Update () 
 {
     if (Input.Get$$anonymous$$ouseButtonUp (0)) 
     {
         Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
         RaycastHit hit;
         if (Physics.Raycast (ray, out hit))
         {
             if (hit.collider.tag == "Ground")
             {
                 agent.enabled = true;
                 obstacle.enabled = false;
                 agent.destination = hit.point;
             }
         }
     }
     if (agent.velocity == Vector3.zero) 
     {
         agent.enabled = false;
         obstacle.enabled = true;
     }
 }

when move, i can get my player agent enabled & obstacle disabled. but when it stop, it doesn't turn into agent disabled obstacle enabled

I see. In your start function:

  void Start () 
  {
      agent = GetComponent<Nav$$anonymous$$eshAgent>();
      obstacle= GetComponent<Nav$$anonymous$$eshObstacle>(); // You wrote "agent" ins$$anonymous$$d of "obstacle"
  }

EDIT: Nvmd, you fixed it.

Just now typo during copy paste.. i have repost the corrected one.. but still not working
