Typing Indicators

Show real-time typing indicators when users are composing messages.

Typing indicators let you show a “user is typing…” animation in your chat UI. The CometChat Unreal SDK delivers these as real-time events through the OnTypingChanged delegate.

Listen for Typing Events

Bind to the OnTypingChanged delegate on the Subsystem to receive typing start/stop notifications.

Blueprint

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

C++

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

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

void AMyActor::HandleTyping(const FCometChatTypingEvent& Event)
{
    if (Event.bIsTyping)
    {
        // Show typing indicator for this user/conversation
        ShowTypingBubble(Event.Uid, Event.ConversationId);
    }
    else
    {
        // Hide typing indicator
        HideTypingBubble(Event.Uid, Event.ConversationId);
    }
}

FCometChatTypingEvent

Property	Type	Description
Uid	FString	The user who started or stopped typing
ConversationId	FString	The conversation where typing is happening
bIsTyping	bool	true when the user starts typing, false when they stop

UI pattern: When bIsTyping is true, show a typing animation (e.g., three bouncing dots). When false, hide it. Consider adding a timeout (e.g., 5 seconds) to auto-hide the indicator in case the stop event is missed.
