PUN API

photonnetwork.connectusingsetting(string gameversion)

gameVersion This client's version number. Users are separated from each other by gameversion (which allows you to make breaking changes).

what does it make separated???

i'm a little bit confusing.

enum ClientState

Detailed connection / networking peer state. PUN implements a loadbalancing and authentication workflow "behind the scenes", so some states will automatically advance to some follow up state. Those states are commented with "(will-change)".

"behind the scenes"????

what is that mean???

in photonnetwork.connectToMaster() when i followed the source i figured out it that photonnetwork class use a method in networkingPeer class.and the networkingPeer is inherited from LoadbalancingPeer class and LoadbalancingPeer class inherited from PhotonPeer class.well , till here everything make sense to me.but in netwrokingPeer class that it use base.Connect() method (PhotonPeer.connect()) to connect Client to Master,nothing will happen till 2 space line later :

 public bool Connect(string serverAddress, ServerConnection type)
    {
        if (PhotonHandler.AppQuits)
        {
            Debug.LogWarning("Ignoring Connect() because app gets closed. If this is an error, check PhotonHandler.AppQuits.");
            return false;
        }

        if (this.State == ClientState.Disconnecting)
        {
            Debug.LogError("Connect() failed. Can't connect while disconnecting (still). Current state: " + PhotonNetwork.connectionStateDetailed);
            return false;
        }
        
        this.cachedServerType = type;
        this.cachedServerAddress = serverAddress;
        this.cachedApplicationName = string.Empty;

        this.SetupProtocol(type);
        
        // connect might fail, if the DNS name can't be resolved or if no network connection is available
        bool connecting = base.Connect(serverAddress, "", this.TokenForInit);
        
/////// Region the MAGIC thing that i cant understand it  

        if (connecting)
        {
            switch (type)
            {
                case ServerConnection.NameServer:
                    State = ClientState.ConnectingToNameServer;
                    break;
                case ServerConnection.MasterServer:
                    State = ClientState.ConnectingToMasterserver;
                    break;
                case ServerConnection.GameServer:
                    State = ClientState.ConnectingToGameserver;
                    break;
            }
        }
/////// EndRegion the MAGIC thing that i cant understand it  

        return connecting;
    }
 

and this is the magic code that i cant figure it out how does this piece of code make the connection and i can receive it from my server.believe me i made this code commented and nothing i would receive from my server.

to my question i want to implement some logic to not everybody can join the master.

    public void OnConnectClicked()
    {
        PhotonPeer peer = new PhotonPeer(_photon , ConnectionProtocol.Udp);
        if (_photon.initialize(peer, "127.0.0.1:5055", "LoadBalancing"))
        {
            Debug.Log("connected");
            connected = true;
        }

    }

    public void OnConnectUsingSettingsClicked()
    {
        Debug.Log(PhotonNetwork.ConnectToMaster("127.0.0.1", 5055 , "LoadBalancing" , "1.0"));
    }

and the funny thing is this that when i use my own peer and use PUN peer (that use LoadbalancingPeer)
they both will connect to server.the only difference that i cant figure it out is that with PUN connection my Master server will authenticate the client and give him a UserID.and i don't know how does it work.i know it will do those authentication with ClientState Enums.but what is that magic came from???What's Next?

when i use PUN custom authentication my server wont redirect peer to OnCustomAuthenticationRequest method.insted it use HandleAuthenticateRequest method.what is the problem??

    public void OnConnectUsingSettingsClicked()
    {
        PhotonNetwork.AuthValues = new AuthenticationValues();
        PhotonNetwork.AuthValues.AuthType = CustomAuthenticationType.Custom;
        PhotonNetwork.AuthValues.UserId = "hasan"; 
        PhotonNetwork.AuthValues.AddAuthParameter("user", "Aidin");
        PhotonNetwork.AuthValues.AddAuthParameter("pass", "123456");
        PhotonNetwork.ConnectUsingSettings("1.1");
    }

well i enabled the customAuth settings from Photon.LoadBalancing.dll.config and now i can get those messages again from customAuthentications.but why using Web???why not using the Photon server to connect to a Database for checking the data's????i cant figure out this.can u explain it to me???
tnx... i'm waiting

how many authenticationHandler exist in loadbalancing Application????i can see some of them.but i want to be sure that my clients wont use some unknown authentications.and how to disable multiplayer login from one IPaddress?
