Using SmartFox with C# (III) : Frequently used functions

If you haven’t read below posts, you might wish to have a quick go through:

Using SmartFox with C# (I) : Installations and 1st handshaking
Using SmartFox with C# (II) : Login and join room

If you are comfortable with above implementations, you might be interested in below frequently called functions. Assuming below variable is instantiated successfully:

private SmartFox client;

To Send a message:

client.Send(new PublicMessageRequest(someMessage));
client.AddEventListener(SFSEvent.PUBLIC_MESSAGE, OnPublicMessage);
private void OnPublicMessage(BaseEvent evt) {
     User sender = (User) evt.Params[“sender”];
     string message = (string) evt.Params[“message”];   
}

To create a room:

var settings = new RoomSettings(“New Room Name”);
settings.maxUsers = 100;
Settings.groupId = “ChatGroup”;
client.Send(new CreateRoomRequest(settings));
client.addEventListener(SFSEvent.ROOM_ADD, OnRoomAdded);

For a zone, to join/remove a room:

client.Send(new Sfs2X.Requests.JoinRoomRequest(roomId));
client.AddEventListener(SFSEvent.ROOM_JOIN, OnRoomJoin);
private void OnRoomJoin(BaseEvent evt) {
     Room room = (Room) evt.Params[“room”];           
     //room.Name,  room.UserList
}

For user to enter/leave a room

client.Send(new Sfs2X.Requests.LeaveRoomRequest());
client.AddEventListener(SFSEvent.USER_EXIT_ROOM, OnUserExitRoom);
private void OnUserExitRoom(BaseEvent evt) { User user = (User) evt.Params[“user”]; }

For more information, have a read on SFSEvent class and Sfs2X.Requests namespace will be vey helpful.

Using SmartFox with C# (II) : Login and join room

The next step after connection with SmartFox server might be login to SmartFox.  If you wish to know how to connect to SmartFox server, refer to this post. Try below code to login to SmartFox:

using Sfs2X;
using Sfs2X.Core;
using Sfs2X.Requests;
using System;

namespace TestSmartFox
{
    class Program
    {
        static private SmartFox client;

        static private string serverIP = "127.0.0.1";
        static private int serverPort = 9933;  
        static public string zone = "BasicExamples";

        static public bool debug = true;
                
        static void Main(string[] args)
        {
            client = new SmartFox();      
            //Important! Set it to true in Unity3D       
            client.ThreadSafeMode = false;             
            client.AddEventListener(SFSEvent.CONNECTION, (evt) =>
            {
                bool bSuccess = (bool)evt.Params["success"];
                Console.WriteLine(client.IsConnected ?
                    "Successfully connected to SmartFox Server" :
                    "Failed to connect to SmartFox Server");

                var request = new LoginRequest("Tracy", "", zone);  //[1]
                client.Send(request);                               //[2]
            });

            client.AddEventListener(SFSEvent.LOGIN, (evt) => {      //[3]
                Console.WriteLine("The User login success");       
            });

            client.Connect(serverIP, serverPort);                    
       }      
    }
}

Using SmartFox with C# (I) : Installations and 1st handshaking

Despite that SmartFox has offered a Unity3D package for easy access SmartFox functionalities for game developers, however it is not very straightforward to directly get to know how to consume SmartFox with C# (Mono), particularly in a step-by-step fashion. This post offers a concise introduction on how to get started with SmartFox in C# in 2 minutes. Hope you love it …

Server setup

• Got o SmartFoxServer web site
• Download and install the latest server in your computer

C# Client

• Got o SmartFoxServer web site
• Download the Client API
• Extract the downloaded zip file, and grab the dll for further use.

Using RabbitMQ in C# (III) Consuming messages from RabbitMQ

It can be found that In earlier posts, setup RabbitMQ and sending messages are a piece of cake using RabbitMQ C# client. Let’s take a further step and see how to consume messages from RabbitMQ.

Create a console application, and add below code:

public static void Main()
{
        var factory = new ConnectionFactory() { HostName = "…" };
        using (var connection = factory.CreateConnection())
        {
            using (var channel = connection.CreateModel())
            {
                //Assuming you have a queue named “whatever” created already
                var consumer = new EventingBasicConsumer(channel);
                consumer.Received += (model, ea) =>
                {
                    var body = ea.Body;
                    var message = Encoding.Default.GetString(body);
                    Console.WriteLine(" [x] Received {0}", message);
                };
                channel.BasicConsume("whatever", true, consumer);

                Console.WriteLine(" Press [enter] to exit.");
                Console.ReadLine();
            }
        }
}

That is it! Simple?

Using RabbitMQ in C# (II) Sending message to RabbitMQ

Create a Winform application, add below UI to the form:

Using RabbitMQ in C# (I) Installation of RabbitMQ

• Go to https://www.rabbitmq.com/ and click the download link:

 

 

• Select the server software on the desired platform and download the setup package. In this example, I will use windows installer.
• Run the windows installer, and you will be prompted to install Erlang, follow the links and download install Erlang:

Using Redis with C# (II): Coding

Now that you have installed Redis on your system, let’s jump to the actual coding using C#. If you wish to get the detailed procedures to install Redis, click here.

• Create a winform project in Visual Studio
• Install the nuget package by running the following command in the Package Manager Console

PM> Install-Package ServiceStack.Redis

Add a button and a button click event handler:

              private void button1_Click(object sender, EventArgs e)
        {
            string elementKey = “TableId”;
            using (var redisClient = new RedisClient(host, port, password))
            {
                if (redisClient.Get<string>(elementKey) == null)
                {
                    redisClient.Set(elementKey, “12345678”);
                }
                else
                    redisClient.Set(elementKey, “87654321”);
                // get value from the cache by key
                var message = “Item value is: “ + redisClient.Get<string>(elementKey);
                MessageBox.Show(message);
            }
        }
