It is also reasonable to have each one of the two arcs as a whole unit, even it is not easy
to determine which part of the arc must be the parent. In such case, we can simply add a
logical parent, which is an empty object that is used as the root of other arc objects.
Let's add two empty objects and name them
arc 1
and
arc 2
. It is always a good idea to
give meaningful names to game objects in the scene, in order to make dealing with scene
elements easier. This is especially useful in large scenes that have many objects.
Position these two empty objects at the center of the scene and add them as children for the
ground. Now add the objects of each arc as children to one of these empty parents. Finally,
add the three boxes as children for the ground. The final hierarchy should look like Illustra-
tion 4.
