Custom Operations

Fufuffu

So, I'm new to Photon Server, and I've added a custom operation. I modified the LoadBalancing GameClientPeer.cs from the default server SDK, I made a class with a mysql dll to connect to a database.
My problem right now, is: I need that the client (Using Unity PUN) sends an operation to the server, I tried using the example code from the server docs, and I don't really know where to use that code, like... I need a reference to the networking peer and that's only in PhotonNetwork.cs, right? Also i can't figure out where to put that operation response void.

Any help is apreciated

Thanks in advice

Still couldn't figure it out Anything is welcome

Hi @Fufuffu,

Thank you for choosing Photon!

To call your custom operation use NetworkingPeer.OpCustom.

Also i can't figure out where to put that operation response void.

You should update NetworkingPeer.OnOperationResponse to handle your custom operation.

@JohnTube Thanks you! So aprecciated! Going into it right now

Sooo, I had been trying for a time... and I still have problems. I found a way of calling the operation, which was:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon;
using ExitGames.Client.Photon;

public class DataBaseLogger : PunBehaviour
{

    private PhotonPeer peer;

    void Start()
    {
        peer = new PhotonPeer(ConnectionProtocol.Tcp);

        var parameter = new Dictionary<byte, object>();
        parameter.Add((byte)100, "test");
        parameter.Add((byte)101, "test");

        peer.OpCustom(50, parameter, true);
    }
}

I created a new peer, as NetworkingPeer.OpCustom() was giving me an error, saying that it needed a reference to a NetworkingPeer.OpCustom(50,parameter,true) non statics.

Is that the way of doing it???

Also, how can I update that NetworkingPeer.OnOperationResponse ???

Sorry for the noob questions

Thanks in advice.

I totally forgot to post this, this code is the modification I made to the GameClientPeer.cs on the LoadBalancing part of the default server sdk

Line 160:

switch (request.OperationCode)
            {
                case (byte)50:
                    var user = (string)request.Parameters[100];
                    var pass = (string)request.Parameters[101];
                    var result = "";
                    
                    if(user != null && pass != null)
                    {
                        result = Photon.LoadBalancing.DatabaseClasses.DBConnect.Login(user, pass);
                    }

                    var response = new OperationResponse
                    {
                        OperationCode = request.OperationCode,
                        ReturnCode = 0,
                        DebugMessage = "Sending login values",
                        Parameters = new System.Collections.Generic.Dictionary<byte, object> { { 102, result } }
                    };
                    this.SendOperationResponse(response, sendParameters);
                    return;

I can also provide the DBConnect class if needed

If you are adding a custom operation for user authentication maybe you should consider Custom Authentication feature.

To implement custom operation in PUN:

Call Custom Ops from PhotonNetwork:

public static bool OpCustom(byte customOpCode, Dictionary<byte, object> customOpParameters, bool sendReliable)
    {
        return networkingPeer.OpCustom(customOpCode, customOpParameters, sendReliable);
    }

You should wrap this method or use something like:

public static bool CustomOpAuthenticate(string user, string pass)
{
byte customOpCode = 50;
Dictionary<byte, object> = new Dictionary<byte, object> {{(byte)100, user},{(byte)101, pass}};
return networkingPeer.OpCustom(customOpCode, customOpParameters, true); // better to use overload method that set "encrypt" to true
}

Handle response in NetworkingPeer:

public void OnOperationResponse(OperationResponse operationResponse)
    {
        if (operationResponse.OperationCode == customOperationCode)
        {
            // handle response
            return;
        }
// ...

In your server side code, I think you should return an error response (ReturnCode != 0) in case of failure.

FInally got it!!! Thank you so much <33 @JohnTube
