By ShiriB:

Look at the target_distance_from_center() function. It only asks for the index of the target. This function should only ask for it too, in order to pass it on. You then call the target_distance_from_center function and tell it the index. it will give you back the distance. Then you align it accordingly. Other than that, this looks good
