Hi everyone! I am from Argentina so excuse my “potato English”
I am new, and I am stuck in this lesson of Laser Defender, because my enemies keep moving to the right
I read that some people have the same issue but they fixed it right.
I am not so lucky 
I tried! everything and nothing happens.
Here is my “EnemySpawner” script. It’s similar to the one that is in the video.
public GameObject enemyPrefab;
public float width = 10f;
public float height = 5f;
public float speed = 5f;
private bool movingRight = true;
private float xmax;
private float xmin;
// Use this for initialization
void Start () {
float distanceToCamera = transform.position.z - Camera.main.transform.position.z;
Vector3 leftBoundary = Camera.main.ViewportToWorldPoint(new Vector3(0, 0, distanceToCamera));
Vector3 rightBoundary = Camera.main.ViewportToWorldPoint(new Vector3(1, 0, distanceToCamera));
xmax = rightBoundary.x;
xmin = leftBoundary.x;
foreach (Transform child in transform)
{
GameObject enemy = Instantiate(enemyPrefab, child.transform.position, Quaternion.identity) as GameObject;
enemy.transform.parent = child;
}
}
public void OnDrawGizmos()
{
Gizmos.DrawWireCube(transform.position, new Vector3 (width, height));
}
// Update is called once per frame
void Update () {
if (movingRight)
{
transform.position += Vector3.right * speed * Time.deltaTime;
}else
{
transform.position += Vector3.left *-speed * Time.deltaTime;
}
float rightEdgeOfFormation = transform.position.x + (0.5f * width);
float leftEdgeOfFormation = transform.position.x - (0.5f * width);
if (leftEdgeOfFormation < xmin || rightEdgeOfFormation > xmax)
{
movingRight=!movingRight;
}
}
}
I change the layout of the camera.
Well, that’s all.
Thank you everyone!
