Retrieve Synchronous Notifications

Last updated on 29 August, 2022 5:01 AM

To retrieve a synchronous notification using the SDK, you need to add the notification delegate.

Unreal Engine

const auto NotificationDelegate = AccelByte::Api::Lobby::FMessageNotif::CreateLambda([](const FAccelByteModelsNotificationMessage& Result)
{
    UE_LOG(LogTemp, Log, TEXT("There is an incoming notification."));
    UE_LOG(LogTemp, Log, TEXT("From: %s \nTo: %s\nTopic: %s"), *Result.From, *Result.To, *Result.Topic);
    UE_LOG(LogTemp, Log, TEXT("Notification: %s"), *Result.Payload);
});

AccelByte::FRegistry::Lobby.SetMessageNotifDelegate(NotificationDelegate);
AccelByte::FRegistry::Lobby.Connect();

Unity

public static void OnReceiveNotification(Result<Notification> result)
{
    Debug.Log(result.IsError);
    Debug.Log("There is an incoming notification.");
    Debug.Log(result.Value.payload);
}

public static void Main(string[] args)
{
    var lobby = AccelBytePlugin.GetLobby();
    lobby.OnNotification += OnReceiveNotification;
    lobby.Connect();
}

You can also filter notifications by topic.

Unreal Engine

const auto NotificationDelegate = AccelByte::Api::Lobby::FMessageNotif::CreateLambda([](const FAccelByteModelsNotificationMessage& Result)
{
    UE_LOG(LogTemp, Log, TEXT("There is an incoming notification."));
    if(Result.Topic == "INGAME")
    {
        UE_LOG(LogTemp, Log, TEXT("Game notification: %s"), *result.Payload);
    }
    Else if(Result.Topic == "EVENT")
    {
        UE_LOG(LogTemp, Log, TEXT("Event notification: %s"), *result.Payload);
    }
});

Unity

public static void OnReceiveNotification(Result<Notification> result)
{
    Debug.Log(result.IsError);
    Debug.Log("There is an incoming notification.");
    switch(result.Value.topic){
        case "INGAME" : Debug.Log("Game notification: " + result.Value.payload); break;
        case "EVENT" : Debug.Log("Event notification: " + result.Value.payload); break;
    }
}
