Lobby Room Events

NetworkClient.Lobby invokes the following events to help you keep track of rooms states and receive messages from other players.

Some of the events (OnLobbyConnectedEvent, OnRoomReadyEvent) are important to keep the matchmaking process running.

If you have a lobby interface, you might be interested in events like OnNewPlayerJoinRoomEvent, OnPlayerLeaveRoomEvent, and OnRoomCustomDataChangeEvent.

Event
OnLobbyConnectedEvent	Invoked when the local player connected to the lobby server.
OnPlayerMessageEvent	Invoked when a new player message is received.
OnRoomCustomDataChangeEvent	Invoked when the room custom data is updated.
OnNewPlayerJoinRoomEvent	Invoked when new players join the local player's room.
OnPlayerLeaveRoomEvent	Invoked when players leave the local player's room.
OnNewRoomOwnerEvent	Invoked when the room owner is changed.
OnRoomStartingEvent	Invoked when the room changes to the Starting state. Game servers are being prepared for the room. If no available game servers are found, FailedToStartRoomEvent will be invoked. If game servers are prepared, RoomReadyEvent will be invoked.
OnRoomReadyEvent	Invoked when the room changes to the Rooms Set state. Game servers for the room are prepared. Use NetworkClient.Instance.ConnectToRoom(Action) to connect to the game servers.
OnFailedToStartRoomEvent	Invoked when the room fails to start. No game servers are available.
OnRoomMessageEvent	Invoked when a new room message is received.
OnKickedEvent	Invoked when the player is kicked from the room by the room owner.

Example

In this example, we added listeners to the lobby room events in the Start() method and removed the listeners in the OnDestroy() method.

void Start() {
	NetworkClient.Lobby.OnRoomReadyEvent += Lobby_OnRoomReadyEvent;
	NetworkClient.Lobby.OnNewPlayerJoinRoomEvent += Lobby_OnNewPlayerJoinRoomEvent;
	NetworkClient.Lobby.OnNewRoomOwnerEvent += Lobby_OnNewRoomOwnerEvent;
	NetworkClient.Lobby.OnRoomStartingEvent += Lobby_OnRoomStartingEvent;
	NetworkClient.Lobby.OnPlayerLeaveRoomEvent += Lobby_OnPlayerLeaveRoomEvent;
	NetworkClient.Lobby.onRoomCustomDataChangeEvent += Lobby_OnRoomCustomDataChangeEvent;
	NetworkClient.Lobby.onFailedToStartRoomEvent += Lobby_OnFailedToStartRoomEvent;
}

void onDestroy() {
	NetworkClient.Lobby.OnRoomReadyEvent -= Lobby_OnRoomReadyEvent;
	NetworkClient.Lobby.OnNewPlayerJoinRoomEvent -= Lobby_OnNewPlayerJoinRoomEvent;
	NetworkClient.Lobby.OnNewRoomOwnerEvent -= Lobby_OnNewRoomOwnerEvent;
	NetworkClient.Lobby.OnRoomStartingEvent -= Lobby_OnRoomStartingEvent;
	NetworkClient.Lobby.OnPlayerLeaveRoomEvent -= Lobby_OnPlayerLeaveRoomEvent;
	NetworkClient.Lobby.onRoomCustomDataChangeEvent -= Lobby_OnRoomCustomDataChangeEvent;
	NetworkClient.Lobby.onFailedToStartRoomEvent -= Lobby_OnFailedToStartRoomEvent;
}

Then, we implemented the listeners

// lobby delegate events
void Lobby_OnRoomReadyEvent(SWRoomReadyEventData eventData) {
	Debug.Log("Room is ready: roomId= " + eventData.roomId);
	NetworkClient.Instance.ConnectToRoom(ConnectedToRoom);
}

void ConnectedToRoom(bool connected) {
	if (connected) {
		Debug.Log("Connected to room");
		SceneManager.LoadScene("Game");
	}
	else {
		Debug.Log("Failed to connect to room");
	}
}

void Lobby_OnNewPlayerJoinRoomEvent(SWJoinRoomEventData eventData) {
	Debug.Log("Player joined room: roomId= " + eventData.roomId + " newPlayerId= " + eventData.newPlayerId);
	if (NetworkClient.Lobby.IsOwner) {
	
		// room owner assigns the new player to team2.
		SWRoom room = NetworkClient.Lobby.RoomData;
		RoomData roomData = room.GetCustomData < RoomData > ();
		roomData.team2.players.Add(eventData.newPlayerId);

		NetworkClient.Lobby.ChangeRoomCustomData(roomData, (bool succeed, object obj) = >{
			Debug.Log("ChangeRoomCustomData successful=" + succeed + " obj= " + obj);
		});
	}
}

void Lobby_OnNewRoomOwnerEvent(SWRoomChangeOwnerEventData eventData) {
	Debug.Log("Room owner changed: roomId= " + eventData.roomId + " newOwnerId= " + eventData.newOwnerId);
}

void Lobby_OnRoomStartingEvent(SWStartRoomEventData eventData) {
	Debug.Log("Room is starting: roomId= " + eventData.roomId + " ownerId= " + eventData.ownerId);
}

void Lobby_OnPlayerLeaveRoomEvent(SWLeaveRoomEventData eventData) {
	Debug.Log("Player left room: roomId= " + eventData.roomId + " leavePlayerId= " + eventData.leavePlayerId);

	if (NetworkClient.Lobby.IsOwner) {
		
		// room owner remove the player from both team.
		SWRoom room = NetworkClient.Lobby.RoomData;
		RoomData roomData = room.GetCustomData < RoomData > ();
		roomData.team2.players.Remove(eventData.leavePlayerId);
		roomData.team1.players.Remove(eventData.leavePlayerId);

		NetworkClient.Lobby.ChangeRoomCustomData(roomData, (bool succeed, object obj) = >{
			Debug.Log("ChangeRoomCustomData successful=" + succeed + " obj= " + obj);
		});
	}
}

void Lobby_OnRoomCustomDataChangeEvent(SWRoomCustomDataChangeEventData eventData) {
	Debug.Log("Room custom data changed: " + eventData);

	SWRoom room = NetworkClient.Lobby.RoomData;
	RoomData roomData = room.GetCustomData < RoomData > ();
	
	// update the player List
	RefreshPlayerList(roomData);
}

void Lobby_OnFailedToStartRoomEvent(SWFailedToStartRoomEventData eventData) {
	Debug.Log("Failed to start room: " + eventData);
}
