2D follow mouse script help!

i have this script that i was following on youtube to get a feel for scripting.

i used this code

Code (JavaScript):

1. #pragma strict
2.  
3. var myCamera : Camera;
4.  
5. function Start () {
6.  
7. }
8.  
9. function Update () {
10.     var vec : Vector3 = myCamera.ScreenToWorldPoint(Input.mousePosition);
11.     vec.x = 0.0;
12.     transform.position = vec;
13. }

the left and right works good but up and down is back words how can i fix this?.

 

Try adding vec.y = vec.y * -1; See if this works!

 

thank you it works
