This chapter covers
- What is SpriteKit?
- What is a pixel?
- How does the coordinate system work in SpriteKit?
- What are the differences between SpriteKit and UIKit?
- How can you use SpriteKit to create a simple app?
In this chapter, you’re going to get your toes wet with SpriteKit. It’ll help you build your confidence, as you’ll see your first simple graphics-based app up and running.
This chapter is for patient typists. I can assure you that you know what all this code means—or will understand it easily—even though the actual code listings are lengthier than you’ve seen so far.
Please don’t hate me, but this chapter is math-intensive. It’s not calculus-level math, but it’s relatively more complex than in the other chapters.
In this book, however, I won’t be going into too much detail with SpriteKit; you either get your toes wet or you dive into the pool. I may cover the more-complicated applications later in the online version of this book as an extension to this chapter.
This chapter is a starter for those who want to learn simple 2D animation for iOS apps.
