Summary
In this chapter you learned what Sprite Kit is and how you create a new Sprite Kit game
using Xcode. You then dove in and created the beginnings of a Sprite Kit game starting
from scratch. You learned about SKNode s and their subclasses, and you used an SKS-
priteNode to add both a background node and a player node.
In the next chapter, you will dig a little deeper into Sprite Kit and discuss the details of the
SKScene , including the coordinate system and anchor points. You will also look at how
a scene's node tree is constructed.
