What's the right way to enter a custom lobby instead of default when connecting to Master?

PipeRock

Hi guys!

What I'm trying to achieve is to get filtered room lists on different lobbies, so if a room is created on lobby A it's only visible on lobby A.

I can create rooms on a specific lobby, but I'm struggling to connect another client to that lobby after. I've checked the documentation and I believe this use case is not quite clear.

Any thoughts to avoid filtering on the client? Am I missing something?

Thank you!

Hi,

Currently you can choose lobby if connect directly to master: https://doc-api.photonengine.com/en/corona/current/modules/loadbalancing.LoadBalancingClient.html#instance:connect
Do you use nameserver instead?

Hi vadim,

Thank you for your answer! Currently I'm using client:connectToRegionMaster("us") to start the connection, so yes I think it's connecting to nameserver before actually connecting to master.

I tried the connect method to connect directly to master, specifying the lobbyName in the options parameter, but I'm getting the following output in the console:

)

Seems like I need to specify which region to use, but I didn't find in options parameter a way to do so. Maybe I should get regions before, but I think this forces me to connect to nameserver.

Any thoughts?

Ok, so I noticed that if you want to connect to master using connect method you have to provide the IP of master server. As I want to be "load balanced" and also specify region I have to stick to the connectToRegionMaster method as specified in every demo/example.

Fortunately, I realized that you can still select which lobby to enter by default intercepting the state change just after state State.ConnectedToMaster using onStateChange.

So, in a very simplified fashion, you could do the following:

function client:onStateChange(state)
    if state == LoadBalancingClient.State.ConnectedToMaster then
        -- Connection to master succeded, set the name of the lobby to join by default
        client.connectOptions["lobbyName"] = "defaultLobbyName"
    end
end

Hopefully, this will not break in the near future

Hope this helps anyone!

Glad that you found a workaround. It should work in the future though I hope we will find a time to add lobby options to nameserver connection calls parameters
