Okay, I need to clerify a few things, this is the code i was using:

Code:

#include <Windows.h>

VOID MainLoop()
{
for (;;Sleep(10))
{
if (GetAsyncKeyState(VK_F1))
{

__asm {

mov esi,0 [0x0067BCBD]

}
}
}
}

BOOL WINAPI DllMain(HMODULE hModule, DWORD dwReason, LPVOID lpReserved)
{
if (dwReason == DLL_PROCESS_ATTACH)
CreateThread(0, 0, (LPTHREAD_START_ROUTINE)MainLoop, 0, 0, 0);
return TRUE;
}

It didn't work, i tried a few addresses but none of them worked.
Let say I have this Cheat Engine script:

Code:

[Enable]
alloc(ItemVac,128)
label(return)
ItemVac:
pushad
mov ecx,[ebp+8]
mov ebx,[ebp-24]
mov [ecx],ebx
mov [ecx+4],eax
mov ecx,eax
mov eax,ebx
lea edx,[eax-19]
mov [ebp-34],edx
lea edx,[ecx-32]
add eax,19
add ecx,A
mov [ebp-30],edx
mov [ebp-2C],eax
mov [ebp-28],ecx
popad
push eax
push [ebp-24]
lea eax,[ebp-34]
jmp return
004B44E7: //50 FF 75 DC 8D 45 CC 50 FF 15
jmp ItemVac
nop
nop
return:

[Disable]
004B44E7:
push eax
push [ebp-24]
lea eax,[ebp-34]

That was just an example, please show me. Smile

+rep for the people which help me

Try:

Code:

mov [0x0067BCBD],0

If you want to make 0x67BCDB have the value = 0.

For the asm script, you will have to create your own codecave and redirect the memory to it.

Could you show me an example, please?

Code:

#define JMP(frm, to) (int)(((int)to - (int)frm) - 5);

void _declspec(naked) MesoCave() //Meso Drop Code cave
{
_asm
{
   mov eax,[iMesoAmount]
   mov [esi+0x000000bc],eax
   jmp dwMesoDropret
}
}

*(BYTE*)dwMesoDropaddy = 0xE9;//JMP
*(DWORD*)(dwMesoDropaddy+1) = JMP(dwMesoDropaddy, MesoCave);//Address

Kinda like that, tho you have to define the values.

[/code]
