Calling WoW functions C++

[f3lix]

Hello, i started to look into wow-devloping yesterday, and found this very websites offset collection, and decided to test my luck.

sadly, it seemed i had none
i tried calling CommandPrintF (thats what its called, i think?) in 2 different ways, typedef and from assembly, although, none were succesfull

what i tried:

typedef void(__cdecl *ConsolePrintType) (char*);
ConsolePrintType ConsolePrint = (ConsolePrintType)0x006F8900;

and
//copypasta from olly
void Print(char* msg)
{
__asm
{
PUSH msg
MOV EAX, 0x006F8900
CALL EAX
ADD ESP, 8
}

}

and then made the call Print("test") or ConsolePrint("test")


Any ideas whats wrong?

ADD ESP, 8 when you push a PTR? Either you magically are running WoW in 64-bit or you mistyped.

Are you injected? My guess is that you aren't, hence you can't do any of what you are trying as you aren't in WoW's virtual memory space and your 0x006F8900 is different then theirs... hence nothing happens.

thanks for the reply,
about the ADD ESP, 8 - i pasted that from a call from the real wow

the other thing about being injected, yes i am pretty sure of that, i debugged it all through a messagebox, well, it looks like the following:

void mainthread()
{
while(true)
{
if(GetAsyncKeyState(VK_NUMPAD7)== -32767)
{
Print("hello ther.");
MessageBox(NULL,L"debug",L"HI",NULL);
}
Sleep(25);
}
}

and the message does indeed showup



solved! nvm!

The ConsoleAddLine function takes 2 parameters, you have to push the color, just push 0 here.

push 0
push msg
mov eax, 0x006F8900
call eax
add esp, 0x8
