In this series, we’re learning how to use SpriteKit to build 2D games for iOS. In this post, we’ll learn about two important features of SpriteKit: actions and physics.
SpriteKit is Apple’s 2D game engine—a rendering engine built on top of OpenGL. It was introduced with iOS 7, and each subsequent release has brought great additions to the framework. With the use of textured sprites, a built-in physics engine, and the very powerful
SKAction class, you can very quickly build functional 2D games.
