where it is on client;??

GAME_CLIENTE_CHAT= 0x9000
GAME_CLIENTE_open=
GAME_CLIENTE_pacht=

where is it???

Cliente

Ok, I didn't understand this.
EDIT:
The opcode 0x9000 is the C->S AcceptHandshake.
The packet with this opcode normally has no data.

This is operations codes, not in PK2...the opcodes are in CLIENT Only.

They're inside the client executable as constants.

Using our favourite user-mode debugger, OllyDbg, and by searching for constants, such as 0x9000 or 0x600D you can easily find those and more.

Now the question... what are they used for?
Basically it's the language spoken by the client and the server. Most of them have a response from the server and in most of the cases they start with 0xB nowadays (or at least on 1.268 was in that way... I'm into something in real life so I've stopped researching/doing anything related to SRO).

Supposed you want to move, so you click the floor. At that time the client sends a message to the server with the OP 0x7021 which means 'requesting movement', then the server does whatever it does (checks if it's a valid move, if you're not dead, etc) and once it has finished the checks it sends back the 0xB021 which is the 'movement response' (offtopic, some people think that this process is because of lag, they're wrong).

When you read things like 'packets' it's generally the OP + operands.

Quick but hope it helps.

Edit: they might have it in that way just in case they've to change the OP codes as for example, last year when Joymax decided to change the OP codes all the time or when switching to another version of SRO (and I personally think it's a good idea but it lacks the pre-built packets that I've mentioned in another thread).

Thanks for the quick explanation boot. I would like to know how would you make the opcode send a move to a certain coordinate? With that said, how do you code a command in C++ to make it send a move packet to a certain coordinate? I have no idea how I can connect a program to the client and to the servers.

Each packet has their own form of handling data.
You never (100%) know how it works.
The two options are: trying to figure it out (parse) yourself or download a silkroad emulator and look how they parsed it (and used it).

dropglock · 11/10/2010, 12:57

lesderid, when you say each packet has their own form of handling data, are you talking about the different parameters that a function may have? Is it safe to say that each packet is a function or a method? I am guessing the silkroad emulator way would be the easiest way to see how things are being handled. With that said, I am going to check out a Silkroad emulator and see how I can relate to what you have been telling me.

Indeed. To compare it, I'll use this example:

Code:

public void Authenticate_6102 (string username, string password, WORD agentserverid, BYTE division)
{
  writer.SetOpcode(0x6102);
  writer.WriteByte(client.sroLocale);
  writer.WriteWord(username.length);
  writer.WriteString(username); //Actually, each character in the string gets written.
  writer.WriteWord(password.length);
  writer.WriteString(password); //Again, chars are written.
  writer.WriteWord(0x0000); //The extra kSRO code. Other versions don't have this WORD.
  writer.WriteWord(agentserverid);
  writer.WriteByte(division);
  client.Send(writer);
}

Note: This is pseudo code, I use pseudo classes and I write to the writer object and I use the client object without creating them first. The reason I did this is to make it easier to explain.

For packet documentation about the LoginServer, use my documentation at

.

Edit: I know it sounds a bit 'scary' in the beginning but once you understand it, it's pretty easy.
