Moving the GameObject - Learn Unity3D Programming with UnityScript - page 116

While you will learn best practices like this for optimizing your game, you'll have to go to the
documentation of your target platform for more specific limitations. For example, to put their
recommendation into practical terms, Metaio also provides an excellent summary of performance
versus polygon count on multiple platforms (and multiple devices) for developers (Figure 5-6 ).

If you are working with an artist who is creating a custom character, it is helpful for them to know if
there are specific polygon count limitations.
Bones are used to control the movement of the character. They make up a skeleton or joint
hierarchy that defines how they move relative to each other, much like parent-child game objects.
Rigging is the creation of this joint hierarchy (Figure 5-7 ).
