Script Deletes itself?

Unity Engine
1

SO basically, Whenever I press teh play to test the game. One of teh scripts on my enimies like deletes itself, but then when I unlick play and go back to edditing it is there. But when U look in the inspector the script is goen during gameplay. Whyd oes it disapear and is tehre a fix?

Do you have a line in your script that says Destroy(this)? This removes the script from the object it’s attached to.

No I do not this is the script:

var target : Transform;
var damp = 1;
var cool = true;

function Start () {
	// Auto setup player as target through tags
	if (target == null  GameObject.FindWithTag("Player"))
		target = GameObject.FindWithTag("Player").transform;
}

function Update () 
{
	if(cool)
	{
			var desiredDirection = target.position - transform.position;
	}		transform.up = Vector3.Slerp(transform.up, -desiredDirection, Time.deltaTime * damp);
	if(Input.GetKeyDown("s"))
	{
		cool = false;
		var desiredDirection2 = target.position - transform.position;
		transform.up = Vector3.Slerp(transform.up, desiredDirection2, Time.deltaTime * damp);
	}
	
}

Nothing special ~ And like I said after I un-clicked the testing it shows back up in the editor
