Hooking WoW Events without LUA-Handler Proc?

[berlinermauer]

Hello Guys.

First: Merry Christmas to all, I'm glad knowing a Community with such experienced users in it

Ok the following: As my development progresses, it would be good to hook some WoW Events in Order to have the Bot handling more fluently and logical.
For that, I plan hooking "OnChatMessage" and the RedText one (maybe with enum's instead of localized text?). Do you recommend another one as well?

I know, that I could simply read the memory and parse it, however there might be some hookable methods that don't support reading their buffer.

To the case I'm writing: I don't have a .NET CLR spawned in WoW.exe. What I'm doing is basically assembling code and write it into a codecave. upon completion, RPM reads the return values (e.g. calling GetLocalizedText() will write a call to it into the codecave, and then read out some values once complete).

The hooks: What I am now thinking of is having another codecave, which is called on a hook-trigger and then sending WM_MESSAGE's to my bot. The only thing I don't know is, whether those are non-LUA-Hooks (which obviously support assembly) or whether those are. If they are LUA-Hooks, they will obviously expect a LUA-Proc as Pointer?

What do you guys think about the idea? Do you have a Guide from where to start?

offtopic: Do you also have some problems with BSDIFF40 patches for some Model files?

Thanks in Advance!

Hook FrameScript::SignalEvent. But take care, back when I did wow stuff it had multiple overloads and one didn't get all the events.
One of them is variadic so you need to do some tricks to hook it.

Can't provide any offsets as my stuff is waaaaaay outdated. It's been quite a while since I did that.
