All you need to do is add an observer to find out when, for example, a GCController objects connects or disconnects. It’s the same pattern with GCKeyboard objects when keyboards connect or disconnect, and with GCMouse objects when pointing devices connect or disconnect. When controllers connect or disconnect from the system, GCController objects are created and removed, and you are sent GCControllerDidConnect and GCControllerDidDisconnect notifications. The basics of the game controller framework is reacting to notifications about different kinds of GCDevice objects connecting and disconnecting and either polling active devices for input state or setting up value-changed handlers to be notified about input state changes. So whether your player is on team circle-square-triangle-cross or on team A-B-X-Y, your game UI will look right for them. And on all platforms, you can build your UI to reflect the symbols and capabilities of the specific controllers the player is holding. On iOS, iPadOS, and tvOS, players can create system-wide and per-application game controller input remappings, which help make your games more customizable and more accessible. Video game controller for macbook code#By abstracting input hardware through the common API, the game controller framework lets you write your input code once without having to worry about how input may have been remapped or the differences among specific controllers, keyboards, or pointing devices. The game controller framework’s goal is making it easy to add support for all different kinds of efficient, low-latency input across Apple platforms. Finally, I want to talk about more actual physical controllers and work through some of our new features. Next, I’m going to show you a new type of virtual game controller, and we’ll write a little code together. Today, I’m going to start with a quick recap of both the how and the why for anybody new to game input on Apple platforms. Thanks for joining me again this year to catch up about game input for iOS, tvOS, and macOS. And I work on Game Technologies at Apple.
