Injecting Interact doesn't work

[skra]

Hi everyone,

I've been reading this forumsection for quite some time now and and i'd say it is a source of nearly infinite wisdome But i've one problem i couldn't solve through reading the related posts. I've managed to read all the things i need from wow's memory, but when i try to interact, nothing happens. the game doesn't even crash.

            uint codeCave = wow.AllocateMemory();
            uint VMT38 = wow.ReadUInt((wow.ReadUInt(obj.BaseAddress)) + (38 * 4));
            wow.Asm.Clear();

            wow.Asm.AddLine("fs mov eax, [0x2C]");
            wow.Asm.AddLine("mov eax, [eax]");
            wow.Asm.AddLine("add eax, 8");
            wow.Asm.AddLine("mov dword [eax], {0}", objectManagerBase);
            wow.Asm.AddLine("mov ecx, {0}", obj.BaseAddress);
            wow.Asm.AddLine("call {0}", VMT38); 
            wow.Asm.AddLine("retn");

            suspendMainThread();
            wow.Asm.InjectAndExecute(codeCave);

            resumeMainThread();
            wow.FreeMemory(codeCave);

This is how i try to do it. I'm sure that my suspend and resume functions work, because the rendering freezes, when i suspend the mainthread, but i have absolutely no clue, why there isn't anything happening.
I would be glad to get evn a hint, it doesn't have to be a complete solution

Thanks!

Guess you didn't read everything... In the 3.1 patch the TLS offset changed from 0x8 to 0x10 as lanman pointed out. A quick look at GetObjectByGUID in a debugger would show you that

wow.Asm.AddLine("add eax, 0x10");

i must have missed that..thanks alot, but i still get no result =(

EDIT: OMG I'm soo stupid...works now. thanks alot =D +rep

One word, LUA.

[skra]

One word, LUA.

why? is it more reliable or safer? or just more simple?

[Shynd]

Simpler. There's a new LUA function called InteractUnit (or something). Far, far easier than VMT, and all that nonsense.

[lanman92]

DoString("InteractUnit("KILLME");

And then you're attacking. No complications or anything. You can do ANYTHING with lua and console. Blizzard is writing the code for us, don't do extra work when you could be reverse engineering...

[skra]

ok, that sounds nice, thanks... i'll try it

[Nesox]

Does that work with GameObjects too, and if so what if you got like 10 GameObjects around with the same name that would work right?
Pretty crappy imo just call Interact on w/e u want and be happy

[lanman92]

Well, I didn't think about that. It just came to mind, so I posted it.

[Nesox]

Ok well allways useful with new lua functions atleast

[Cypher]

Yeah the LUA interact func is only good for helping update across patches, usless to actually call in a bot.

[skra]

but i need dostring for injected spellcasting, right?

[lanman92]

It's much easier with DoString. "CastSpellByName("Demon Armor");" and you're goin.

[skra]

Ok, i read your DoString method (http://www.mmowned.com/forums/wow-me...ml#post1480627). Am i right that the variable luaDoString is 0x0049AE30?
