gpg::GameServices

#include <game_services.h>

The starting point for interacting with Google Play Games.

Summary

Game Services Lifecycle

An instance of the GameServices class is created via a GameServices::Builder. When created, the instance is initially not signed into the Game Services (that is, IsAuthorized() will return false). A silent sign-in attempt is initiated in the background, and may succeed if a user was signed in at the end of a previous session. Until the completion of this silent sign-in attempt, any user authentication UI (for example, sign-in and/or sign-out buttons) should be disabled or hidden.

At the completion of this silent sign-in attempt, the OnAuthActionFinished callback for the GameServices instance (registered with GameServices::Builder::SetOnAuthActionFinished) will be notified. If the callback arguments reflect a successful sign-in attempt, the instance can be assumed to be connected to Game Services (that is, IsAuthorized() will return true), and sign-out UI should be enabled. If the callback argument reflects a failed sign-in attempt, sign-in UI should be enabled.

Explicit sign-out via the SignOut() method should be invoked only at user request. This requests a transition to a signed out state. The completion of this transition is indicated by an invocation of the OnAuthActionFinished callback. Until such a time as this callback is invoked, other GameServices APIs (including StartAuthorizationUI()) should not be called.

When a GameServices instance is destructed, it will block until there are no pending operations to avoid data loss. If this block-on-destruction behavior is not desired, a Flush() should be issued and the GameServices instance should be kept alive until the Flush() completes.

For GameServices to function properly on Android versions less than 4.0, the owning Activity must call lifecycle callbacks. See AndroidSupport.

Classes

gpg::GameServices::Builder

Used for creating and configuring an instance of the GameServices class.

Public types

FlushCallback

std::function< void(FlushStatus)> FlushCallback

Defines a callback type that receives the result (status) of a Flush operation.

Used in Flush().

Public functions

Achievements

AchievementManager & Achievements()

Provides a reference to the AchievementManager object used for accessing and manipulating achievements.

Achievements

const AchievementManager & Achievements() const 

Provides a const reference to the AchievementManager object used for accessing and manipulating achievements.

Events

EventManager & Events()

Provides a reference to the EventManager object used for accessing and manipulating events.

Events

const EventManager & Events() const 

Provides a const reference to the EventManager object used for accessing and manipulating events.

Flush

void Flush(
  FlushCallback callback
)

Asynchronously flushes the main dispatch queue, and returns the status of the flush to the provided FlushCallback.

Possible statuses are: FLUSHED, ERROR_INTERNAL, and ERROR_VERSION_UPDATE_REQUIRED.

FlushBlocking

FlushStatus FlushBlocking()

Synchronously flushes and gets a result (status) of the flush.

Possible statuses are: FLUSHED, ERROR_INTERNAL, ERROR_NOT_AUTHORIZED, ERROR_VERSION_UPDATE_REQUIRED, and ERROR_TIMEOUT. Leaving this timeout unspecified makes this function call equivalent to calling FlushStatus FlushBlocking(Timeout), with Timeout specified as 10 years.

FlushBlocking

FlushStatus FlushBlocking(
  Timeout timeout
)

Synchronously flushes and gets a result (status) of the flush.

Possible statuses are: FLUSHED, ERROR_INTERNAL, ERROR_NOT_AUTHORIZED, ERROR_VERSION_UPDATE_REQUIRED, and ERROR_TIMEOUT. Specify the timeout as an arbitrary number of milliseconds.
