[WarCraft III] Game State Checking (v1.21)

[Perma]

Thanks again to Palomino's notes for clarification on the global class.

.data

        WC3FXN_GlobalClass      dd 6F84CC20h 

.code

Warcraft_CheckGameState proc

        ;Get the pointer to Warcraft's global class.
        mov eax, WC3FXN_GlobalClass
        mov eax, dword ptr ds:[eax]

        ;Check to see if we're in a game and return true/false.
        .if dword ptr [eax+1ACh] == 00000000h
            mov eax, 0
        .else
            mov eax, 1
        .endif
        ret

Warcraft_CheckGameState endp

Moved to the Warcraft hacking related section.

uhm, wouldn't you be better off just doing, say:

Warcraft_CheckGameState proc

        ;Get the pointer to Warcraft's global class.
        mov eax, WC3FXN_GlobalClass
        mov eax, dword ptr ds:[eax]

        ;Check to see if we're in a game and return true/false.
        mov eax, dword ptr ds:[eax+1AC]
        ret

Warcraft_CheckGameState endp

It'll still work the same way if you are using boolean logic.

[Perma]

Suppose it would.

[tinman]

how do i implement the hooked function into my cheating program?

[Perma]

If your program is written in Masm, then you can simply do:

call Warcraft_CheckGameState

[tinman]

i'm using C, inject an DLL that compiled with this function and call it when needed?

[Perma]

That's correct. It will return true if the user is in a game, and false if not.

[tinman]

I tried the text out function and Game State checking function... both end up with fatal error after calling the functions.

[Perma]

Perhaps one of more C-oriented gurus can help you with this, but I assume that the function would have to be a naked function. Maybe post your converted C function here so I can check it?

[tinman]

int Warcraft_CheckGameState()
{
	static int WC3FXN_GlobalClass = 0x6F84CC20;
	__asm
	{
		;Get the pointer to Warcraft's global class.
		mov eax, WC3FXN_GlobalClass
		mov eax, dword ptr ds:[eax]

		;Check to see if we're in a game and return true/false.
		mov eax, dword ptr ds:[eax+1AC]
		ret  
	}
}

[Perma]

Pretty sure the address should be stored as a long, and I don't think you can use those comments in C either.

[dt]

#define GameState (*(int*)(*(int*)0x6F84CC20+0x1AC))

Simple as that.

[Perma]

What he said.

[tinman]

int Warcraft_CheckGameState()
{
	static long WC3FXN_GlobalClass = 0x6F84CC20;
	__asm
	{
		mov eax, WC3FXN_GlobalClass
		mov eax, dword ptr ds:[eax]
		mov eax, dword ptr ds:[eax+0x1AC]
		ret
	}
}

these are the changes i made.
when it executes mov eax, dword ptr ds:[eax]
it still causes fatal error.

Simple as that.

simple statement... complicated pointers

1. get the pointer from 0x6F84CC20, assume it is A
2. A + 0x1AC, assume it is B
3. get the pointer from B, return the value.

Did i understand it correctly?

what is the purpose of the type cast (int *)?

[oMBra]

Can this be made with autoIT?

Of course, if AutoIt has the capability to read memory of another process.

The code in this thread seems to be obsolete, a updated version has been posted by Rufus in this thread.
