An AI character always has some aspects of an autonomous robot with some predefined skills such as either they will be seeking some characters in the game or they will evade themselves from the playing character. All these behaviors are called steering behaviors.

Getting ready

In this chapter, we will create a new game to demonstrate all the steering behaviors. To get started with the implementation, let us create a new project. Open Xcode and go to File | New | Project, and then select iOS | Application | SpriteKit Game. In the pop up provide...
