Rotating planes only on the y axis

Hi community
What i wanna do:
An object should always turn towards camera ... but only on the y axis ... so it won't turn up when i jump ...

Im currently rotating it with this script:

var Distance;
var Target : Transform;

function Update ()
{
lookAt();

}
function lookAt ()
{
var rotation = Quaternion.LookRotation(Target.position - transform.position);
transform.rotation = rotation;
}

However, I do not know how I can restrict the rotation to the y axis

I made a code for that some months ago, here I'll share it to you, it have the option to make the sprite only look in Y an the option for it to llok like a GUI, IT ONLY WORKS WITH QUADs or nested objects.

Code (JavaScript):

1. #pragma strict
2.  
3. var typeGui:boolean;//set this to true to face the camera always, else Y only
4.  
5.  
6. function Update(){
7.     transform.rotation=Camera.main.transform.rotation;
8. }
9.  
10. function LateUpdate(){
11. if(!typeGui){
12.     transform.rotation.eulerAngles.x=0;
13.     transform.rotation.eulerAngles.z=0;
14. }  
15. }

Cheers!

 

Thanks <3
