A sprite could be an image for the player, but also a coin, an enemy, or even the floor that a player walks on. When sprites are mentioned in the context of SpriteKit, it is meant to refer to one of the nodes that are visible on the screen.

 

Because SpriteKit has a built-in physics engine, it can detect collisions between objects, apply forces to them, and more. This is pretty similar to what UIKit Dynamics is capable of. If you're a bit rusty on what UIKit Dynamics are and how they work, be sure to have a look at Chapter 4, Immersing Your Users with Animation for a refresher.

To render content, SpriteKit uses scenes. These scenes can...
