Count players in lobby

Hello, how can I make a player count in a lobby, for example 1/2?
I can not understand

Code (CSharp):

1. public override void OnRoomListUpdate(List<RoomInfo> roomList)
2.     {
3.         foreach(Transform trans in roomListContent)
4.         {
5.             Destroy(trans.gameObject);
6.         }
7.         for (int i = 0; i < roomList.Count; i++)
8.         {
9.             if (roomList[i].RemovedFromList)
10.                 continue;
11.             Instantiate(roomListItemPrefab, roomListContent).GetComponent<RoomListItem>().SetUp(roomList[i]);
12.         }
13.     }

 

The OnRoomListUpdate provides an update to any list you already keep. Don't destroy the complete content when just receiving updates...

Yes, you could count all players in the room list (using RoomInfo).
Alternatively, there are "Lobby Stats" provided in intervals.
