Binding to Event Dispatchers

Making your custom UI react to the server

To make your custom UI react to the server, you must bind Custom Events in your Widget Blueprint to the MP_ChatClient component's Event Dispatchers.

Step 1: Get the Component Reference

Inside your main Chat Widget's Event Construct, get the Owning Player Controller and call Get Chat Client. Save this reference as a variable.

Step 2: Bind OnMessageReceived

This is the core event that updates your chat window. Drag off your reference and call Bind Event to OnMessageReceived.
  1. 1
    Create a Custom Event (e.g., HandleNewMessage).
  2. 2
    Break the FMP_ChatMessage struct output.
  3. 3
    Access SenderName, MessageText, and Timestamp to populate your text blocks.

Step 3: Bind Room Events

To dynamically add/remove chat tabs, bind to OnRoomJoined and OnRoomLeft. Use these to spawn or destroy UI tabs associated with the incoming RoomID.
