New SteamChatRoomClient Event for friend message acknowledgement

[laees]

Problem description

I'm trying to detect when a friend chat message has been acknowledge by the logged in user (not the friend). The message acknowledgement is happening in a different session, meaning that my program should be informed when my desktop client reads a friend message.

Possible solution

An event that is fired when the logged in user has read a message with a callback containing:

• steamid_friend - The SteamID object for the friend
• unread_message_count - How many unread messages are contained in this session

Current workaround

I tried polling getActiveFriendMessageSessions or getFriendMessageHistory at a set interval to detect when unread_message_count changes. This however is unnecessarily resource intensive and is limited by the polling rate.

I hope this is technically possible.

I have found a way to do this by altering ./components/chatroom.js. All I had to do was to add an Event of type FriendMessagesClient.NotifyAckMessageEcho#1 under the //Handlers section

SteamUserBase.prototype._handlerManager.add('FriendMessagesClient.NotifyAckMessageEcho#1', function (body) {
  body = preProcessObject(body);

  /* 
  console.log("Body:\n" + body);
  */

  this.chat.emit("NotifyAckMessageEcho", body);
});
