var ufoSpeed : int;
var ufoBullet : Rigidbody;
var ufoBulletSpeed : int;
function Start()
{
	transform.position.x = Random.Range( -7,7);

}
function Update () {
	amtToMove = ufoSpeed * Time.deltaTime;
	
	transform.Translate(Vector3.up * amtToMove);
	
	if(transform.position.y <= 4.1)
	{
		ufoSpeed = 0;
		FireBullet();
		
	}
		
}
function FireBullet()
{
	var tmp : Rigidbody = Instantiate(ufoBullet,transform.position,transform.rotation);
	tmp.velocity = transform.position * ufoBulletSpeed;

	
}

 if(transform.position.y <= 4.1)
   {
      ufoSpeed = 0;
      FireBullet();
      
   }

This is in the Update() funtion, FireBullet() will be called every frame while transform.position.y <= 4.1

as atomicJ said, your FireBullet() function will be called every frame. Call FireBullet() on specific event like mouse click or whatever you like.
