How to send data with tag, serialization, class?

[nvh2001]

client:

while (true)
{
    if (!client.IsOpened)
    {
        client.Open(new Host("127.0.0.1", 2001));
    }
    else
    {
        short tag = 20; // login tag
        string user = "helloeeeeee";
        string password = "1234eeeeeeee";
        // Send the data
        client.ToData(????);
        break;
    }
}

server

client.OnData(data =>
{
    
});

thanks!!!

Yes it's possible! Use Byter is included in Netly project (no need external install)

e.g. (Byter and Netly Event) = 💯 + 😄

using Byter;

// create writer
Writer w = new Writer();
w.Add((int)1234567890); // tag
w.Add((string)"Alecio"); // user
w.Add((string)"Alecio123"); // password
byte[] BYTER_BUFFER = w.GetBytes();

// send data
client.ToEvent("my login event", BYTER_BUFFER);

// receive data
client.OnEvent((string name, byte[] data) =>
{
    if (name == "my login event")
   {
        Reader r = new Reader(data);
        string tag = r.Read<string>();
        string user = r.Read<string>();
        string password = r.Read<string>();
        
        // check is it's sucess, if false mean error on read any or all data. It don't make exception.
        if (!r.Sucess)
        {
            client.ToEvent("login error event", "Invalid tag, user, or password! try again.");
        }

        Console.WriteLine($"Login event [{r.Sucess?"sucess": "error"}]: tag={tag}, user={user}, password={password}");
   }
});

e.g. (Byter and Without Netly Event) = 💯 + 🎃

using Byter;

// create writer
Writer w = new Writer();
w.Add((string)"my login event"); // message id
w.Add((int)1234567890); // tag
w.Add((string)"Alecio"); // user
w.Add((string)"Alecio123"); // password
byte[] BYTER_BUFFER = w.GetBytes();

// send data
client.ToData(BYTER_BUFFER);

// receive data
client.OnData((byte[] data) =>
{
    Reader r = new Reader(data);
    string messageId = r.Read<string>();

    if (messageId == "my login event" && r.Sucess)
    {        
        string tag = r.Read<string>();
        string user = r.Read<string>();
        string password = r.Read<string>();
        
        // check is it's sucess, if false mean error on read any or all data. It don't make exception.
        if (!r.Sucess)
        {
            client.ToData("Invalid tag, user, or password! try again.");
        }

        Console.WriteLine($"Login event [{r.Sucess?"sucess": "error"}]: tag={tag}, user={user}, password={password}");
    }
    else
    {
        Console.WriteLine("This isn't login data");
    }
});

Can u make tag (object) for client like

client.tag[0] = PlayerModel; //(ref of class)
var me = (PlayerModel)(client.tag[0])
me.coin += 1000;

Don't need find player of client, just use tag.
I dont know its ok or not :))))

yes it's very possible, but use different way 👍
Netly using Byter to serialize a data, you can use any library for do this like protobuf, json, .... Netly only send bytes and receive bytes, Go try understand byter first, for you understand the flow.

client.tag[0] = PlayerModel; //(ref of class)
var me = (PlayerModel)(client.tag[0])
me.coin += 1000;

Byter work like this: 👍

# CLIENT
using Byter;

// create write stack
var r = new Reader();
// add elements on stack
r.Write((int)1000); // player id
w.Write((string)"Random"); // player name
w.Write((string)"Region"); // player region ...

client.ToEvent("update-player-position", r.GetBytes());

# SERVER
server.OnEnter((client) =>
{
    client.OnEvent((eventName, eventData) =>
    {
        if (eventName == "update-player-position")
        {
            var r  = new Reader(eventData);
            int playerId = r.Read<int>();
            string playerName = r.Read<string>();
            string playerLocation  = r.Read<string>();
            if (r.Sucess == false) { /* error on parse: ignore this message */ }
            else { /* sucess */ }
        }
    });
});

But i know you need a simple way to received data serialized... I have a Good news for you, Byter Version 3 will support class and struct, maybe list and array.

will look like this: 💯

public class Person
{
    public long Id { get; set; }
    public string Name { get; set; }
    public int Coin { get; set; }
    public Person() {  }
    ...
}

# CLIENT
Person myPerson = new Person();
person.* = *;
...

var b = new By(); // create byter instance
b.Add(myPerson); // add my person to buffer

client.ToEvent("person-data", b.Buffer); // send my person buffer

# SERVER

server.On.Accept((client) =>
{
      client.On.Event((name, data) =>
      {
         if (name == "person-data")
         {
              By b = new By(data);
              Person myPerson = b.Get<Person>();
          
              if (b.IsError == false)
              {
                  // my person is valid can use now e.g. if (myperson.Name == "Abc") { ... }
              } 
          }
    });
});

But you alse can do this in Netly your current version, using diferent way

e.g.

public class Person
{
    public long Id { get; set; }
    public string Name { get; set; }
    public int Coin { get; set; }
    public Person() {  }\

    public byte[] GetBuffer()
    {
        Writer w = new Writer();
        w.Write(Id);
        w.Write(Name);
        w.Write(Coin);
        return w.GetBytes();
    }

    public static Person? GetPerson(byte[] buffer)
    {
          Reader r = new Reader(buffer);
          Person person = new Person();
          person.Id = r.Read<long>();
          person.Name = r.Read<string>();
          person.Coin = r.Read<int>();
          
          if (r.Sucess) return person;
          else return null;
    }
}

# CLIENT
var myPerson = new Person();
myPerson.Coin = 100;

client.ToEvent("any-name", myPerson.GetBuffer());

# SERVER

server.OnEnter((client) =>
{
      client.OnEvent((name, data) =>
      {
         if (name == "any-name")
         {
              Person myPerson = Person.GetPerson();
 
              if (person != null)
              {
                    // use your person now
              }
          }
    });
});

Can I using event name with other type like enum (byte, short, int..) ? string is too large :)))

[alec1o]

Of course... You can use any name that you want. but if your event name is null or empty: event won't be send (will be ignored)
