User Presence

Track when users come online, go offline, or go away by binding to the OnPresenceChanged delegate on the Subsystem.

Blueprint

1. Get a reference to the CometChat Subsystem
2. Drag off and search for On Presence Changed
3. Use Bind Event to connect it to a custom event
4. The custom event receives an FCometChatPresence parameter

C++

void AMyActor::BeginPlay()
{
    Super::BeginPlay();

    UCometChatSubsystem* Chat = GetGameInstance()->GetSubsystem<UCometChatSubsystem>();
    Chat->OnPresenceChanged.AddDynamic(this, &AMyActor::HandlePresence);
}

void AMyActor::HandlePresence(const FCometChatPresence& Presence)
{
    switch (Presence.Status)
    {
    case ECometChatPresenceStatus::Online:
        UE_LOG(LogTemp, Log, TEXT("%s is online"), *Presence.Uid);
        break;
    case ECometChatPresenceStatus::Offline:
        UE_LOG(LogTemp, Log, TEXT("%s went offline"), *Presence.Uid);
        break;
    case ECometChatPresenceStatus::Away:
        UE_LOG(LogTemp, Log, TEXT("%s is away"), *Presence.Uid);
        break;
    }
}
