GameKitMBS.authenticateHandler(LocalPlayer as GKLocalPlayerMBS, viewController as NSViewControllerMBS, error as NSErrorMBS, tag as Variant, viewControllerHandle as Integer)

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
event	GameKit	MBS MacFrameworks Plugin	13.0	✅ Yes	❌ No	❌ No	❌ No	Desktop only

The event called when game center needs authentication.

viewController: This parameter is nil if the authentication process is complete. Otherwise, it contains a view controller that your game should display to the player.
error: This parameter contains an error object that describes any error that occurred.

Your game should authenticate the player as early as possible after launching, ideally as soon as you can present a user interface to the player. For example, your game may be launched because the player accepted an invitation to join a match or to take a turn in a turn-based match, so you want your game to authenticate the player and process the match invitation as quickly as possible. After you set a handler, authentication begins automatically and is repeated when your game moves to the background and then back to the foreground.

During the authentication process, Game Kit calls your handler one or more times to handle specific authentication events. Your handler must handle three kinds of events:

• If the device does not have an authenticated player, Game Kit passes a view controller to your authenticate handler. When presented, this view controller displays the authentication user interface. Your game should pause other activities that require user interaction (such as your game loop), present this view controller and then return. When the player finishes interacting with it, the view controller is dismissed automatically.
• If the authentication process succeeded, theGKLocalPlayer singleton object's authenticated property is set to true and the object's other properties are set to match those of the connected player.
• If the authentication process failed, the GKLocalPlayer singleton object's authenticated property is set to false and the object's other properties are cleared.

Each time the authentication handler is called, the data stored in the local player singleton object may have changed. A new player may have logged into the device or the player may have simply logged out from Game Center. Because of both of these possibilities, your authentication handler must be prepared to update any other objects that assume that a particular player is logged in. For more information, see "Authenticating the Local Player in a Multitasking Application" in Game Center Programming Guide.
