I have been working on a script that will allow the player to click on objects in a scene to get a closer look at the actual object. When this script is attached to an object, that object is then selectable.

Once a selectable object is clicked, the object is temporarily moved to a different position (the EmptyPosition game object), along with the main camera (and the "player" is turned off), where the player can rotate the object to get a better view. They can then click "Return" on the GUI and it will take the player back to the actual location in the scene where the character is.

Testing this script, it works fine when attaching it to a single cube. The problem arises when I attach it to an object that has children beneath it. Nothing happens. Is it possible to make this script treat that parent object and its children all as one object?

using System.Collections;
