GetObjectByGUID return always NULL

[Cypher]

I just hook EndScene via a Virtual Function hook by obtaining the already created IDirect3DDevice9 pointer stored in the CGxDevice3d class.

Ooooohh well la-di-da then Mr Smartypants.

Hardly.

Hooking D3D funcs is harrrrrd. Amirite?

Besides, hooking CreateDevice allows me to grab the window's handle in a generic way and set up input detection. Much easier than reversing out a static pointer in every game.

And anyway, even if I could be bothered to do it in a manner that doesn't require me to create and hook the process on startup it would be pointless, I've got stuff that needs to be done then anyway.

Silly jew. Trix are for kids.

Hello.

Thank you all for the responses.

I have find a way, to hook EndScene without hooking any other function.
Its really simple, you need to create your own Direct3DDevice9 and then you can get easy the address of EndScene and hook it. This works great and now it dont crash anymore if i interact with all. ^^

This works only if WoW is running in windowed-mode, if its in fullscreen, i need to get the address of EndScene in my Injector and then pass it to my injected dll. If you create an additional Direct3DDevice9 in a fullscreen-application, weird things will happen. ^^

If someone is interested in the sourcecode, i will post it here.

Another question: If i would get Lua_DoString to work, do i need CastSpellById anymore? Currently Lua_DoString dont work, dont know why, nothing happens.

In WoWXBase it is defined as follows:
typedef void ( __cdecl * tLua_Dostring )( char * pszString, char * pszString2, void * pState );

FindPattern find this address:
Lua_DoString: 0077DEF0

i call the function like this:
Lua_DoString("/cast Throw\r\n", NULL, NULL);

NARF. I searched this and other forums for an example how to use Lua_DoString, but i found nothing.

Please, do post the code.
You can find examples on how to call DoString in the 3.0.2 Information thread btw.

i call the function like this:
Lua_DoString("/cast Throw\r\n", NULL, NULL);

I seem to remember seeing a post where someone (probably Cypher or Kynox) saying that you have to pass the same string as arguments one and two. Lua_DoString("/cast Throw", "/cast Throw", NULL);, or something. I may be wrong, so I suggest attempting to find the thread I'm thinking of, but you might give it a shot anyway.

Hey, what exactly are you passing to the function. Could you give me a real example so I could see?

typedef void (__cdecl * tDoString)(const char * pszExec1, const char * pszExec2, void * pState = 0);
tDoString MyDoString = (tDoString)(0x0077DEF0);
MyDoString("ForceQuit()","ForceQuit()");

WARNING: The code above is untested and off the top of my head. It should work though.

If you can't get it working reply again and I'll write up some test code for you.

Its obvious you're well above the level of the moron in that other thread and the fact that you've been able to jump into IDA and do some research on your own makes me more than happy to give you a hand.

That's what Cypher posted
Also i don't think that

Lua_DoString("/cast Throw", "/cast Throw")

would work i think it would have to be something like

Lua_DoString("CastSpell(1, \"spell\")", "CastSpell(1, \"spell\")");

Not sure but.

EDIT:

MyDoString("CastSpellByName(\"Fireball\")", "CastSpellByName(\"Fireball\")");

Would be better...

In the attachment is the code.

Thanks to you all. Now it works properly.

I thought i could use the text, i would paste into the WoW macro-managment (/macro), but this won´t work.

Lua_DoString("CastSpellByName(\"Throw\");", "CastSpellByName(\"Throw\");", NULL);
works great! Thanks to you all.
