List of rooms while in room

VladK

Hello.

I have a setup where I have a lot of rooms and I can visit them all. But some rooms can be "instanced" - any user can create his own copy of that room or should be able to join any copy of the room created by other users.

I have a problem when it comes to show the list of a particular copies of room to user. Basically I need to get the list of all rooms that exist on the server and filter them out by name (copies have the room name as a prefix: Conference_1, Conference_2, etc.). I tried to use this example (the one with Custom Room LIsting):
https://doc.photonengine.com/zh-tw/realtime/current/lobby-and-matchmaking/matchmaking-and-lobby#sql_lobby_type

But each time I call "PhotonNetwork.NetworkingClient.OpGetGameList(sqlLobby, sqlLobbyFilter);"
I get this error:
Operation GetGameList (217) not allowed on current server (GameServer)

What do I do?

You only get a room list while being on the Master Server (and not in a room).
This is by design.

That's some design... So no options for me here, but to make some external webserver, where I will literally store rooms and send them to users when needed?

There are four options:
- not list rooms while players should be playing
- use the LoadBalancingClient class to connect to the Master Server, join a lobby and fetch the list (+1 CCU each)
- keep the list externally
- host Photon Servers yourself and modify them to update one another
