Enemies walk to waypoints and stop in specific ones

Hey thats the point... i just have a multiple waypoint set for every enemy, and i now included some code to make them stop in Stay tagged ones... but it just glitches out .. :( this is the new code for it

var Waypoint:Transform [];

var speed = 5;

var currentWaypoint:int;

var loop:boolean = true;

var viewAngle:float = 360;

var InDistance:Vector3;

var PlayerPos:Vector3;

var InDistanceMag:float;

var Seen:boolean = false;

var InAngle:float;

var DistanceToSpot:float = 7;

var Alarm:GameObject;

var SubjectInSight:Transform;

var Lives:int = 4;

var Hit:AudioClip[];

var TimeToStay:float;

function Awake(){

Waypoint[0] = transform;

Alarm = GameObject.Find("Alarm");

}

function Update () {

PlayerPos = GameObject.Find("Player").transform.position;

if(currentWaypoint < Waypoint.Length && Waypoint[currentWaypoint].tag != "Stay"){

var target:Vector3 = Waypoint[currentWaypoint].position;

var moveDirection:Vector3 = target - transform.position;

var velocity = rigidbody.velocity;

if(moveDirection.magnitude < 1){

currentWaypoint ++;

}

else if(moveDirection.magnitude > 1 ){

 velocity = moveDirection.normalized * speed *Time.deltaTime;

 

}

} if(Waypoint[currentWaypoint].CompareTag("Stay")){

 Stay();

 

}

if(currentWaypoint > Waypoint.Length){

 if(loop){

     currentWaypoint = 0;

     

 }

 else{

 velocity = Vector3.zero;

 }

}

rigidbody.velocity = velocity;

transform.LookAt(Vector3(target.x,transform.position.y,target.z));

THE CODE CONTINUES, BUT IT JUST ISNT IMPORTANT UNTIL

function Stay(){

 currentWaypoint ++;

 print("Yielding");

 yield WaitForSeconds(TimeToStay);

}

Ok thats the new code, but the one that worked till the moment was :

var Waypoint:Transform [];

var speed = 5;

var currentWaypoint:int;

var loop:boolean = true;

var viewAngle:float = 360;

var InDistance:Vector3;

var PlayerPos:Vector3;

var InDistanceMag:float;

var Seen:boolean = false;

var InAngle:float;

var DistanceToSpot:float = 7;

var Alarm:GameObject;

var SubjectInSight:Transform;

var Lives:int = 4;

var Hit:AudioClip[];

function Awake(){

Waypoint[0] = transform;

Alarm = GameObject.Find("Alarm");

}

function Update () {

PlayerPos = GameObject.Find("Player").transform.position;

if(currentWaypoint < Waypoint.Length){

var target:Vector3 = Waypoint[currentWaypoint].position;

var moveDirection:Vector3 = target - transform.position;

var velocity = rigidbody.velocity;

if(moveDirection.magnitude < 1){

currentWaypoint ++;

}

else{

 velocity = moveDirection.normalized * speed *Time.deltaTime;

 

}

}

else{

 if(loop){

     currentWaypoint = 0;

     

 }

 else{

 velocity = Vector3.zero;

 }

}

rigidbody.velocity = velocity;

transform.LookAt(Vector3(target.x,transform.position.y,target.z));

//CHECK SPOTTING PLAYER

InDistance = PlayerPos - transform.position;

InDistance.y = 0;

InAngle = Vector3.Angle(PlayerPos - transform.position,transform.forward);

if(InDistance.magnitude <= DistanceToSpot && InAngle <= viewAngle)

 {

 var hit:RaycastHit;

 Physics.Raycast(transform.position,Vector3.Normalize(PlayerPos - transform.position),hit,50);

 if(hit.collider.CompareTag("wall")){

 Seen = false;



 }

else if(hit.collider.CompareTag("Player")){

 Seen = true;

 

 

}

InDistanceMag = InDistance.magnitude;

}

//ACTIVATE ALARM!!

if(Seen==true){

 Alarm.SendMessage("Trigger");

 stopmoving();

}

}

function OnCollisionEnter(other:Collision){

 if(other.gameObject.tag == ("Bullet")){

     

     Lives -= 1;

     audio.clip = Hit[Random.Range(0,2)];

     audio.Play();

     Destroy(other.gameObject);

     if(Lives == 0){

     Destroy (gameObject);

     

     }

 }

}

function stopmoving(){

 Instantiate(SubjectInSight,Vector3(transform.position.x,transform.position.y + 1,transform.position.z),Quaternion.identity);

 transform.LookAt(PlayerPos);

 Destroy(this);

}
