Adding Animation and Movement with Actions
In the previous chapter, you created a new project using the default iOS Game template. You cleared out the boilerplate code and started to set up your first scene by adding the background and foreground sprite nodes using the SKSpriteNode class.
In this chapter, you’ll add the player sprite node to the scene and focus on adding movement and animation using another SpriteKit class: SKAction.
