Destroy gameObject but not AI

[john-essy]

Hi there the problem i am having is when i destroy an enemy all other enimies stop targeting me and stay still i will show both scripts that i think are doing this first one is AI seconds is AI health

function Awake()
{
animation["Walk"].layer =0;

}

var waypoint : Transform[];
static public var speed : float = 20;
private var currentWaypoint : int;
var loop : boolean = true;
var player : Transform;


function Update() {
		
	var distFromPlayer : Vector3 = player.position - 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 if (distFromPlayer.magnitude < 20){ // If we are close to the enemy

		velocity = Vector3.zero;
		target = player.position;
		velocity = (player.position - transform.position).normalized * speed;
		if((player.position - waypoint[currentWaypoint].position).magnitude > 20){
		target = waypoint[currentWaypoint].position;
		velocity = moveDirection.normalized * speed;
		}
	}
		else{
			velocity = moveDirection.normalized * speed;
			}
	}
	else{
		if(loop){
			currentWaypoint = 0;
		
		}
		else{
			velocity = Vector3.zero;
		}
		
	}
	
		rigidbody.velocity =velocity;
		transform.LookAt(target);
		
	
}

AI Health

var health : int = 100;
var prefab : Transform;
var sound : AudioClip;
var Points : Transform;
var smallleaf : Transform;
var branch : Transform;


function OnCollisionEnter (hit : Collision)


{
	if(hit.gameObject.tag == "Bottle")
	{
		
		
		
		health -= 25;// Take 25 away from the monsters health
		
		AudioSource.PlayClipAtPoint(sound,transform.position);// When the mosnetr is hit play a sound at it's position
		
		var instanceBullet2=Instantiate(smallleaf,transform.position, transform.rotation);//clone an object when the monster is hit
		
		Debug.Log (health);//tell us if the health is worrking 
		
		animation.Play("Hit");//Play the animation Hit
		
		yield WaitForSeconds(0.6);//Wait for 0.6 seconds before playing the next animation
		
		animation.CrossFade("Walk");// Smoothly transition between hit and walk
		
		animation.Play("Walk");// Play the animation Walk
	
		
	if (health <= 0)
		
		{
		animation.Play("LookAround");// Play the animation if we are dead
		
		MonsterTreeAI1.speed = 0;
		
		yield WaitForSeconds(3);//play the animation in it's full length
		
		Destroy(gameObject);
		
		AudioSource.PlayClipAtPoint(sound,transform.position);//Play a AudioClip at the objects position
		
		var instanceBullet=Instantiate(prefab, transform.position, transform.rotation);//spawn a prefab
		
		var instanceBullet1=Instantiate(Points, transform.position, transform.rotation);//spawn a prefab
		
		var instanceBullet3=Instantiate(branch, transform.position, Quaternion.identity); //spawn a prefab
	
		
		}
		
	
		
	

	}

}

Not sure, but it might be your static variable speed that is shared?
Try to remove the keyword “static” that keeps it global.
