Can someone help me please?

Follow Player when in sight script!

Hello everyone I have this javascript...

 import UnityEngine.SceneManagement;
 
 
 public var fieldOfViewAngle : float = 150f;             // Number of degrees, centred on forward, for the enemy see.
 public var playerInSight : boolean;                     // Whether or not the player is currently sighted.
 
 private var nav : NavMeshAgent;                         // Reference to the NavMeshAgent component.
 private var player : GameObject;                        // Reference to the player.
 
 
 function Awake ()
 {
     // Setting up the references.
     nav = GetComponent(NavMeshAgent);
     player = GameObject.FindGameObjectWithTag("Player");
     playerInSight = false;
 }
 
 
 function Update ()
 {
     if (playerInSight)
     {
       nav.SetDestination(player.transform.position);
     }
 }
 
 
 function OnTriggerStay (other : Collider)
     {
         
         // If the player has entered the trigger sphere...
         if(other.gameObject.tag == "Player")
         {
             // By default the player is not in sight.
             
            
             // Create a vector from the enemy to the player and store the angle between it and forward.
             var direction : Vector3 = other.transform.position - transform.position;
             var angle : float = Vector3.Angle(direction, transform.forward);
             
             // If the angle between forward and where the player is, is less than half the angle of view...
             if(angle < fieldOfViewAngle * 0.5f)
             {
                 var hit : RaycastHit;
                 //Debug.Log("intrigger");
                 // ... and if a raycast towards the player hits something...
                 if(Physics.Linecast(transform.position , other.transform.position)!=true)
                 {                                     
                         // ... the player is in sight.
                         playerInSight = true;
                        if (Vector3.Distance(transform.position , other.transform.position)<=1.5)
                        {
                                SceneManager.LoadScene (SceneManager.GetActiveScene ().buildIndex);
                        }

             if(other.GetComponent.<Collider>().gameObject.tag == "Player")

                 Invoke("LooseSightDelayed",1);

         }
 
        /* function CalculatePathLength (targetPosition : Vector3)

                 var pathLength : float = 0;
                 // Increment the path length by an amount equal to the distance between each waypoint and the next.
                 for(var j = 0; j < allWayPoints.Length - 1; j++)
                 {
                     pathLength += Vector3.Distance(allWayPoints[j], allWayPoints[j + 1]);
                 }
     
                 return pathLength;
             }*/

and I am not too experienced with this particular type of script but I got help and made it work! I am making a game using c# and want all the scripts to be the same type so I was wondering is there anyone out there that would take the time to convert this script into c# for me please and thank you! I would really appreciate it!!!
