Class GCController

  • All Implemented Interfaces:
    GCDevice, NSObject
    public class GCController
extends NSObject
implements GCDevice
    Controllers are available to an application that links to GameController.framework. There are 2 ways to access controllers paired to the system, adopt both to ensure the best user experience: 1: Querying for the the current array or controllers using [GCController controllers]. 2: Registering for Connection/Disconnection notifications from NSNotificationCenter. Only controllers that support one of the allowed profiles, such as GCExtendedGamepad, will be enumerated. Check for the profile supported before using a controller in your application. Ignore a controller that doesn't support a profile that suits your application, as the user will expect their controller to either be fully supported or not supported at all.

      • startWirelessControllerDiscoveryWithCompletionHandler

        public static void startWirelessControllerDiscoveryWithCompletionHandler​(GCController.Block_startWirelessControllerDiscoveryWithCompletionHandler completionHandler)
        Start discovery of new wireless controllers that are discoverable. This is an asynchronous and the supplied completionHandler will get called once no more devices can be found. If there are already multiple controllers available for use, there may be little reason to automatically start discovery of new wireless controllers. In this situation it may be best to allow the user to start discovery manually via in-game UI. Once discovery has started new controllers will notify themselves as connected via GCControllerDidConnectNotification. As the notification arrives the controller is also available in the controllers array. The completionHandler could be used to update UI and/or game state to indicate that no more controllers will be found and the current set of controllers is what is available for use in the game. If a completionHandler was provided, it will be called once when discovery stops. Either from an explicit call to stopWirelessControllerDiscovery or from timing out or stopping in its natural course of operation. Thus the completionHandler will at most be called once per call to startWirelessControllerDiscoveryWithCompletionHandler:. The completionHandler may also not get called at all, if for example startWirelessControllerDiscoveryWithCompletionHandler: is called multiple times during dicovery. For this case the net effect is that the completionHandler is replaced with each call and only the last one set before discovery stops will be called.
        Parameters:
        completionHandler - an optional handler that is called when discovery stops. (may be nil, in which case you will not be notified when discovery stops)

      • stopWirelessControllerDiscovery

        public static void stopWirelessControllerDiscovery()
        If no more controllers are needed, depending on game state or number of controllers supported by a game, the discovery process can be stopped. Calling stopWirelessControllerDiscovery when no discovery is currently in progress will return immediately without any effect, thus it is safe to call even if the completionHandler of startWirelessControllerDiscoveryWithCompletionHandler: has been called.

      • controllerPausedHandler

        public GCController.Block_controllerPausedHandler_ret controllerPausedHandler()
        Set this block to be notified when a user intends to suspend or resume the current game state. A controller will have a button dedicated to suspending and resuming play and invoking context sensitive actions. During event handling the system will notify the application using this block such that the application can handle the suspension and resumption from the given controller. Use this to implement your canonical transition to a pause menu for example if that is your application's desired handling of suspension in play. You may pause and resume based on game state as well so the event is only called each time the pause/resume button is pressed. [@note] This handler has been deprecated in favor of the Menu button found on GCMicroGamepad and GCExtendedGamepad.

        microGamepad(), extendedGamepad()

      • gamepad

        public GCGamepad gamepad()
        Gets the profile for the controller that suits current application. There are several supported profiles, with an additional optional profile for motion as well. Each controller may be able to map its inputs into all profiles or just one kind of profile. Query for the controller profile that suits your game, the simplest kind will be supported by the broadest variety of controllers. A controller supporting the Extended Gamepad profile for example supports the Gamepad profile and more. As such it can always be used just in the Gamepad profile if that suits the game. A physical controller that supports a profile must support it completely. That means that all buttons and axis inputs must be valid inputs that a developer can utilize. If a controller does not support the given profile the returned value will be nil. Use this to filter controllers if the application requires a specific kind of profile.

      • handlerQueue

        public NSObject handlerQueue()
        Description copied from interface: GCDevice
        The dispatch queue that element value change handlers are submitted on. The default queue is main, and setting this to any other queue will make value change handlers dispatch async on the given queue. This is useful if the main game loop of the application is not on main, or if input logic is handled on another thread from the main game loop.

      • isAttachedToDevice

        public boolean isAttachedToDevice()
        A controller may be form fitting or otherwise closely attached to the device. This closeness to other inputs on the device may suggest that interaction with the device may use other inputs easily. This is presented to developers to allow them to make informed decisions about UI and interactions to choose for their game in this situation.

      • motion

        public GCMotion motion()
        Gets the motion input profile. This profile is optional and may be available if the controller is attached to a device that supports motion. If this is nil the controller does not support motion input and only the gamepad & extendedGamepad profiles are available.
        See Also:
        gamepad(), extendedGamepad()

      • playerIndex

        public long playerIndex()
        A player index for the controller, defaults to GCControllerPlayerIndexUnset. This can be set both for the application to keep track of controllers and as a signal to make a controller display a player index on a set of LEDs or some other mechanism. A controller is not guaranteed to have a visual display of the playerIndex, playerIndex does not persist for a controller with regards to a system. Negative values less than GCControllerPlayerIndexUnset will just map back to GCControllerPlayerIndexUnset when read back.

      • setControllerPausedHandler

        public void setControllerPausedHandler​(GCController.Block_setControllerPausedHandler value)
        Set this block to be notified when a user intends to suspend or resume the current game state. A controller will have a button dedicated to suspending and resuming play and invoking context sensitive actions. During event handling the system will notify the application using this block such that the application can handle the suspension and resumption from the given controller.

        public void setHandlerQueue​(NSObject value)
        Description copied from interface: GCDevice
        The dispatch queue that element value change handlers are submitted on. The default queue is main, and setting this to any other queue will make value change handlers dispatch async on the given queue. This is useful if the main game loop of the application is not on main, or if input logic is handled on another thread from the main game loop.

      • setPlayerIndex

        public void setPlayerIndex​(long value)
        A player index for the controller, defaults to GCControllerPlayerIndexUnset. This can be set both for the application to keep track of controllers and as a signal to make a controller display a player index on a set of LEDs or some other mechanism. A controller is not guaranteed to have a visual display of the playerIndex, playerIndex does not persist for a controller with regards to a system. Negative values less than GCControllerPlayerIndexUnset will just map back to GCControllerPlayerIndexUnset when read back.

      • vendorName

        public java.lang.String vendorName()
        Description copied from interface: GCDevice
        A vendor supplied name. May be nil, and is not guaranteed to be unique. This should not be used as a key in a dictionary, but simply as a way to present some basic information about the device in testing or to the user.
        Specified by:
        vendorName in interface GCDevice

      • capture

        public GCController capture()
        Polls the state vector of the controller and saves it to a new and writable instance of GCController. If your application is heavily multithreaded this may also be useful to guarantee atomicity of input handling as a snapshot will not change based on user input once it is taken.
        Returns:
        A new controller with the duplicated state vector of the current controller
        See Also:
        snapshot

      • controllerWithExtendedGamepad

        public static GCController controllerWithExtendedGamepad()
        Creates a controller with an extended gamepad profile. This controller will be considered a snapshot, allowing developers to write to any GCControllerElement of its profiles.
        Returns:
        A new controller with an extended gamepad profile
        See Also:
        snapshot

      • controllerWithMicroGamepad

        public static GCController controllerWithMicroGamepad()
        Creates a controller with a micro gamepad profile. This controller will be considered a snapshot, allowing developers to write to any GCControllerElement of its profiles.
        Returns:
        A new controller with a micro gamepad profile
        See Also:
        snapshot

      • isSnapshot

        public boolean isSnapshot()
        A controller may represent a real device managed by the operating system, or a virtual snapshot created by the developer. If a controller is directly created by the developer, it is considered to be a snapshot, allowing direct writes to any GCControllerElement of its profiles. If the controller is not snapshot, the system will reject any write requests to GCControllerElement.

      • productCategory

        public java.lang.String productCategory()
        Description copied from interface: GCDevice
        The product category the controller belongs to. This is useful for setting appropriate UI elements based on what type of device is connected.
        Specified by:
        productCategory in interface GCDevice

      • battery

        public GCDeviceBattery battery()
        Gets the battery information if controller supports one This property is useful when you try to notify your user to change or charge controller before it runs out of battery life or simply display the current battery level and status.

      • current

        public static GCController current()
        The most recently used game controller. If a user actuates a game controller input, that controller will become the current one. [@note] This is useful for single player games where you only care about whether an input is pressed, and not where it came from. You will still need to register for changes to GCController.current so that your UI can remain up-to-date with the current controller.

      • haptics

        public GCDeviceHaptics haptics()
        Gets the haptics for the controller, if one exists. Use this property to create CHHapticEngine instances according to your needs. [@note] Haptics are a drain on the controller's battery, and can be distracting when used excessively.

      • light

        public GCDeviceLight light()
        Gets the light for the controller, if one exists. A controller's light can be used to signal information to the player, such as using different light colors based on the player index. It can also be used to react to in-game events and enhance user immersion.

      • physicalInputProfile

        public GCPhysicalInputProfile physicalInputProfile()
        Description copied from interface: GCDevice
        Gets the physical input profile for the device. [@note] This is equivalent to the controller's gamepad, microGamepad, or extendedGamepad instance.
        Specified by:
