I'm playing around with a space shooter tutorial I found on the unity website, and I'm trying to make a boss enemy that appears when I reach a certain amount of points. But I can't figure out how to make the boss move to the center of the screen. I think it has something to do with the mover script I made for the other enemies. The other enemies move all the way to the bottom of the screen. How can I make a boss mover script that just has it move half way on the screen?

```
public class Mover : MonoBehaviour {
public float speed;
private Rigidbody rb;

void Start()
{
    rb = GetComponent<Rigidbody>();
    rb.velocity = transform.forward * speed;
}
}

```
