Need help getting started

[winhog]

Hi, I have never made a bot before but I know a decent amount of winsock and c++ and I was wondering if anyone could help me get started.  I'm trying to make a bot that will connect as warcraft 3 (or the expansion).

What should I send (and to what server) in order to just get logged on? I looked around and I saw lists of bytes to send, but I didn't see anywhere that mentioned the username or password or cd-key. 

Sorry...I know very little about this. Thanks for any help.

Are you going to use BNLS or local hashing?

If the former:

http://www.valhallalegends.com/yoni/BNLSProtocolSpec.txt

To initiate a binary connection to Battle.net, send the byte 0x01, and then follow this login sequence (the following are packets, most of them documented either in the above link, or at http://bnetdocs.valhallalegends.com )

C->S: 0x50
S->C: 0x25
S->C: 0x50
C->S: 0x25 (optional)
C->S: 0x51
S->C: 0x51

After this, it all depends on what you want to do (create an account, log in to an account - or upgrade your account - if I'm correct you'll never be doing the latter with WarCraft 3)

Thanks, the documentation and sequence should be enough to get me started.

Can you recommend any tutorials/documention on how I could do local hashing instead of BNLS?

There is no publicly released sourcecode for War3 in C++.  There is a C# version, and a Java version, both opensource, and supported by their authors (the Java one being mine).  There is a stolen, unsupported C++ along with a .dll, but I'll cry if you use it . 

There is also a server something like BNLS written in Java that can be run locally that does it, but I don't think it has been released yet.

[winhog]

Hmmm. I'm guessing I'll use bnls for now...but what's a link to your java version?

[iago]

It's on "iago's forum" on this board, stickied.

[winhog]

Wow that may be a bit above my head  .

Anyway, I think I'm making some progress with my program but I can't really be sure. I've only made it to message 0x50 to battle.net. Can anyone confirm that the values I'm getting back aren't way out of whack?

NLSRevision is 2
MPQName is IX86ver4.mpq
SessionKey is seemingly random
Checksum value some strange string with A = something, B = something, A = A^S...I really have no idea what it means.

Those values seem reasonable to me...but hey some encouragement that I'm at least on the right track would be nice too.

Hit a major snag with 0x51...

I'm not sure if you can figure out what's wrong just by looking at the packet but here it is

Edited:  Some weirdness with my send/recv was causing problems...so it's looking better now but still not quite right


Edit #2...wow, one extra 00 at the end can cause a lot of problems.  Sorry for my noobness, I can get authenticated by b.net now.

[iago]

Session key is indeed random.
NLSRevision is right.
MPQName is right.

And that version string is a mini-program to verify your files.

[winhog]

Thanks very much!!  I've got a working chat client now! The problem is i seem to be able to do a LOT of things that get me banned from b.net for a few minutes...but I'll figure that out soon enough I suppose. 

An EditBox control also doesn't seem to be a good chat window since it scrolls to the very top everytime i setwindowtext on it. Do most people make their own sort of chat window class, or is there something about EditBox that I'm missing?

[iago]

I think most use a RichTextbox (RTB).  Just make sure you filter out RTB Control Codes (I don't know what they are).

[R.a.B.B.i.T]

When parsing messages to be displayed, always just flip the backslash in "{\rtf", or get rid of it, because "\rtf" is required before any RichText control code (as iago puts it) can be used, like a type identifier, I suppose.

[Skywing]

The proper way to do that is to insert text with RTF parsing off (look up the EM_STREAMIN message).

And who here besides you uses "the proper way" to do anything?  We all half-assishly create most of our code.  Silly Skywing.

But yes, that's the way you should do it if you want good code, otherwise you can just be lazy like 90% of the other programmers and simply flip the backslash.
