Rotate object depending on other object

Unity Engine

Hi …
First look this unity scene: (Control ball with WSAD keys)
https://dl.dropboxusercontent.com/u/42356492/Unity/rollBall/WebPlayer/WebPlayer.html

My target is making cube rotate only around Y-Axis to face the same direction of rolling ball ?

I make this script to cube, but cube not face ball direction correctly !!

Script:

var targ1 : Transform;
var targ2 : Transform;

function Update () {
	 var orientation = targ1.transform.rotation.y;
     targ2.transform.rotation.y = orientation;
}

Unity Scene:
https://dl.dropboxusercontent.com/u/42356492/Unity/rollBall/WebPlayer/WebPlayer.html

The cube must rotate to face rolling ball direction …

From your description, it seems that you need to use Transform.LookAt

Let me know how it goes. I can’t see your Unity project. The webplayer did not load in my browser.
