In chapter 19, we develop a reusable component that emulates the Xbox 360 controller using the keyboard. This configurable component is a drop-in replacement for the standard controller APIs. It merges input from any controllers that are actually plugged in so that the player can transition from keyboard to controller and back seamlessly. The game never knows where player input is coming from, it just handles it as if the player is using a controller.
