Hi there,

Thanks.

function Update () 
{
	if (Input.touchCount == 1) 
    {
		var theTouch : Touch = Input.GetTouch(0);
		var ray = Camera.main.ScreenPointToRay(theTouch.position);
		var hit : RaycastHit;
		if (Physics.Raycast(ray, hit))
		{
			print("oh yah");
			print("ray" + ray);
			print("hit.collider.gameObject.name" + hit.collider.gameObject.name);
		}
	}      
}
