Game Development Reference
In-Depth Information
Summary
In this chapter, we explored how to create a frame-by-frame animation where the items or actors in
the game update their location incrementally, many times a second. You learned how to synchronize
an animation loop with the refresh rate of the device screen, and how to describe the state of a game
in a display-agnostic way, freeing you from the coordinate system of the host
UIView
. We continued
our exploration of this type of game by looking at some simple techniques to create animations and
adding life to our actors.
