Reading Chat Out-of-Process

[RiseAndShine]

So I'm finally getting a little used to IDA & Olly and found a way read the ChatChannels. This should be useful for noticing annoying tells. I've been leeching for a long time now, so I thought I might wanna share something ^^.

----------------

Chat-Messages start at:
0x104BCE4

There you'll find something like:
Type: [7] Channel: [] Player Name: [Dude] Text: [Sup!]

The Typenumber tells you which kind of message it is:
17: Public-Channels (Trade, LFG, etc.)
7: Whisper-FROM
9: Whisper-TO
1: Say
4: Guild
5: Guild-Officer

Hadn't have a chance yet to get the type of Party & Raid, but it should be easy to determine.

The next Chat-Message will be at:
+0x17C0

------------------

Now there's just one more problem, when you start up the client the first message will be at 0x104BCE4, the second at 0x104BCE4 + 0x17C0, third at 0x104BCE4 + (2*0x17C0) and so on...
This continues until the 60 message at (0x104BCE4 + (59*0x17C0)). If there's a new Chat-Message after this point the message will be stored at beginning again (0x104BCE4). However the old ones remain in memory until new messages overwrite them. The way I handled this, is just to check for different messages in between 2 reading loops, which seems to work well enough.


Here's my code, may be it explains it a little bit clearer:

Nice job.

here's a complete list of chat types (may be a bit out of date):

    public enum ChatType : byte
    {
        ADDON = 0,
        SAY = 1,
        PARTY = 2,
        RAID = 3,
        GUILD = 4,
        OFFICER = 5,
        YELL = 6,
        WHISPER = 7,
        WHISPER_MOB = 8,
        WHISPER_INFORM = 9,
        EMOTE = 10,
        TEXT_EMOTE = 11,
        MONSTER_SAY = 12,
        MONSTER_PARTY = 13,
        MONSTER_YELL = 14,
        MONSTER_WHISPER = 15,
        MONSTER_EMOTE = 16,

        DND = 24,
        IGNORED = 25,
        SKILL = 26,
        LOOT = 27,

        BATTLEGROUND_LEADER = 45,
        RESTRICTED = 46,
    };

Nice; I used this quite a while back when I coded my cross-game whisper and chat.

It would read the chat out of process for multiple games and you could type something like..

;w USERNAME:MESSAGE HERE

Then it would attempt to send the message to said user if they were logged on, then post it to the game they were in if they were in one OR open a chat window.

Was kind of cool..

You can also hook Broadcast Event and grab messages from there.

You can also hook Broadcast Event and grab messages from there.

Or CGChat_C__AddChatMessage

I don't know c#, what exactly i have to do for read chat? I need any kind of assembly?
I get error on this when i try to run.

public void StartReading()
{
PrepareReading();
Thread t = new Thread(ReadChat);
t.Start();
}

Thread can find!

No, but you will have to reverse the values of the new pointers and offsets. Not hard. Look at the lua. Love the lua...

[miLl3niUm]

Can you explain what this does for the newbs?

[lanman92]

What? Is the explanation at the top not good enough for you???
