Game - Client / Client - Game communication with Packets

[ѕeмa™ 352]

Some one know how send here other table from player.player?

void CHARACTER::SendTitleSystem() // test client-game 
{
	if (!GetDesc())
	{
		return;
	}
 
	TPacketGCMetin2Dev Metin2DevGC;
 
	Metin2DevGC.byHeader = HEADER_GC_METIN2DEV;
	Metin2DevGC.M2int = GetPlayerID(); // change here to a new table from player.player

	GetDesc()->Packet(&Metin2DevGC, sizeof(TPacketGCMetin2Dev));
}

for example a new table created , named "test"???

Thanks.

 I tried (ctrl+c, ctrl+v) the client-game communication, but doesn't works for me 

 

The sysser write this:

Analyze: login phase does not handle this packet! header 58

 

What i doing wrong?

 

thanks for helping me!

Hi Sanchez

I have a problem ...

I see the "none" (I posted a type of children in text), but directly after clicking on the button, I have a black screen ...

I have to force quit

I use the event function:

vid = net.SendM2DevPacket(player.GetTargetVID())
self.test.SetText(str(vid))

 

Thanks !

Push ...

(I'm just getting disconnected when I press the test button.) My function (53 is a test):

net.SendM2DevPacket(53)

I have an error in the sysser when my crash client ...:

SYSERR: Jun 24 21:11:11.804832 :: Process: UNKNOWN HEADER: 44, LAST HEADER: 0(0), REMAIN BYTES: 6, fd: 25

Header 44: Header CG Pong
Regarding the condition:

bool CPythonNetworkStream::SendMetin2DevOrgPacket(int data)
{
    TPacketCGMetin2DevOrg M2DevPacket;
    M2DevPacket.byHeader = HEADER_CG_METIN2DEVORG;
    M2DevPacket.data = data;

    if (!Send(sizeof(M2DevPacket), &M2DevPacket))
        return false;

    LogBox("test");
    return SendSequence();
}

The fonction return SendSequence and not false !
I did a test to see if the packet is received by the game:

        case HEADER_CG_METIN2DEVORG:
            sys_log(0, "TEST");
            Metin2DevReceivePacket(ch, c_pData);
            break;

But I have nothing in the syslog.
The packet is not received.

I don't understand at all what the problem is ....

replace this net.SendM2DevPacket(53) with this

net.SendM2DevPacket(self,53)

[kodepiko 39]

would be nice to see how to deal with string type value in packet at clientside, I'm getting mad trying to catch string at clientside, always some errors.. 

[Asha 8]

Thank you. Really helped me to understand how it works packets in Metin2. A great like.

Is there any part of the game which uses UDP?

Also I'd like to point out that the code in the original post is bad, the structure should be packed to ensure that there is no padding - this is standard practise.

You're the real MVP! Thanks a bunch mate, most appreciated!

why dont I see anything log-related 

[nefdulin 105]

Okay, so if you do all the steps in the first post you will NOT see any log box appering. This is not a bug or an error on your end. The problem(!) is very simple. We created the logic of what happens when we send our packet but we didn't send the packet at all. And since this is a new packet we've written the game will not send it for us. Let's say we want to send the packet when we pickup an item. To achieve that all we have to do is call "SendMetin2DevPacket" function inside PickupItem(DWORD dwVID) function. You can find the PickupItem function inside char_item.cpp file.

Just a question - Does what youre trying to do now comply with the terms of service/license agreement of this game?

And also, what is this WPE you mention?

As far as I know, It doesn't.

 

Thanks for the guide btw. Very helpful.

def Button1_Event(self net.SendM2DevPacket(player.GetTargetVID())

Hello, Ik its an old post, but on the last bit, with the button creation, can't see to figure out in which module (python file) to put the class method? And under what class? And also, who's "net", if anybody could help, would really appreciate it!

Now add the last function to game.py, this will be called by the binary:

	def BINARY_M2DEV_Test(self, M2int):
		import dbg
		dbg.LogBox(str(M2int))

 
Finally, lets check how it works:
 

 
 

I can't understand this part. like how to check if it works? starting the server and login into the game nothing is happening. 

I've followed the "tutorial" as is, verifying it multiple times, but tbh nothing happens also, no errors. (using tmp4 base)
