How do I change the Target in the MousOrbit Script?
It tried this

aTarget = GameObject.Find("MyObject").Transform;
target = aTarget;

But it doesn’t work.
Any ideas?

var target : Transform;

function Awake(){

if(GameObject.Find("MyObject"))target = GameObject.Find("MyObject").transform;
}

Then drag the target that you want to that.
