waypoint script - stop at targets

Hello everyone, first off, I am very new to programing and am still studying but could really use a hand with this one. Thanks in advance. So I have this great waypoint script Im using and I dont know how to alter it so I can get the mob to stop moving when it gets in a variable defined range of any object with a certain tag. Any help is greatly appreciated! Thanks!

This is the current script im working with:

var waypoints : Transform[];

var speed : float = 5.0; var Turnspeed : float = 2;

var ChangeWaypointRange : float = 5; var endPoint : Transform;

private var targetwaypoint : int;

function Start() {

 if(waypoints.Length <= 0){
 Debug.Log("No waypoints");
 enabled = false;
 }
 
 targetwaypoint = 0;
 endPoint = waypoints[targetwaypoint];
 }
 

function Update () {

var distanceFromEndpoint = Vector3.Distance(endPoint.position, transform.position);

if (distanceFromEndpoint <= ChangeWaypointRange) { targetwaypoint ++;

}

 if(targetwaypoint>=waypoints.Length)
 {
 
         targetwaypoint = 0;
 }
     

endPoint = waypoints[targetwaypoint];

var rotateDirection = Quaternion.LookRotation(endPoint.position - transform.position);

transform.rotation = Quaternion.Lerp(transform.rotation,rotateDirection,Turnspeed*Time.deltaTime);

transform.Translate(Vector3.forward*speed*Time.deltaTime);

}
