i was wondering how i would move the mouse to x postion in c++.

i have this function(see below), but gameguard seems to block me moving the mouse. i named the file EvoMouExec.exe, the game i play is Mu online global. so how would i move the mouse in c++? thanks for any help =]

Code:
void SetMousePos(int x, int y)
{
    double fScreenWidth = ::GetSystemMetrics( SM_CXSCREEN )-1;
    double fScreenHeight = ::GetSystemMetrics( SM_CYSCREEN )-1;
    double fx = x*(65535.0f/fScreenWidth);
    double fy = y*(65535.0f/fScreenHeight);
   
    INPUT inp;
    inp.type = INPUT_MOUSE;
    inp.mi.dx = fx;
    inp.mi.dy = fy;
    inp.mi.dwFlags = MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE;
    inp.mi.time = 0;
    SendInput(1, &inp, sizeof(INPUT));
}

SendInput hooked by gameguard just like all user32.dll api's
to bypass it jump 5 bytes over the hook
Code:

DWORD _si = (DWORD)GetProcAddress(GetModuleHandle("User32.Dll"),"SendInput");

__declspec(naked) unsigned int WINAPI _SendInput(UINT nInputs,LPINPUT pInputs, int cbSize)
{
  __asm
  {
    mov edi,edi
    push ebp
    mov ebp,esp
    jmp dword ptr ds:[_si]
  }
}

I'm pretty sure SendInput is blocked on r0 not r3. Kiki had a driver to bypass it, but that appears to be patched (i BSOD using it with GG).

why don't you use java...

Code:

import java.awt.*;

public class fuck {
    public static void main(String args[]) {
        Robot f = new Robot();
        f.moveMouse(10, 10); //move mouse to pos 10, 10
    }
}

because java sucks. And it's blocked anyways aswell.

I think in windows.h there is SetCursorPos. Include windows.h and just do
SetCursorPos(int x, int y); it's not sending anything to the game so gameguard shouldn't care.

The part of Robot class in Java that sends a click is blocked, so the method is crap because you won't be able to do anything other than move the mouse. If you argue that clicking or input isn't blocked in java then you are a moron. I've used the robot in java and it failed.

I'm not sure if bypassed SetCursorPos is needed. I think MAKELPARAM might do it. However, just to be safe, use it. Or just test it out later.

Code:

DWORD SCP = (DWORD)GetProcAddress(LoadLibrary(L"user32.dll")), "SetCursorPos") + 5;

__declspec(naked) BOOL WINAPI SetCursorPosX(int X, int Y)
{
   __asm
   {
      push   ebp
      mov    ebp, esp
      jmp    dword ptr [SCP]
   }
}

Code:

DWORD PMA = (DWORD)GetProcAddress(LoadLibrary(L"user32.dll")), "PostMessageA") + 5;

__declspec(naked) BOOL WINAPI PostMessageX(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)
{
   __asm
   {
      push   ebp
      mov    ebp, esp
      jmp    dword ptr [PMA]
   }
}


I guess you do something like this:
Code:

. . .
SetCursorPosX(x, y);
PostMessageX(hWnd, WM_LBUTTONDOWN, NULL, MAKELPARAM(x, y));
PostMessageX(hWnd, WM_LBUTTONUP, NULL, MAKELPARAM(x, y));
. . .


Or you could use the POINT structure so you don't have to keep re-writing the coords.
Code:

. . .
POINT coords = { x, y };
SetCursorPos(coords.x, coords.y);
PostMessageX(hWnd, WM_LBUTTONDOWN, NULL, MAKELPARAM(coords.x, coords.y));
PostMessageX(hWnd, WM_LBUTTONUP, NULL, MAKELPARAM(coords.x, coords.y));

visual studio (costs but you can easily torrent)
visual C++ express (free, just google it)

when you prefix a string with L it is used as a unicode string.

either remove the L 's

or use the unicode versions of the functions.

LoadLibraryW instead of LoadLibraryA

unicode:
Code:

DWORD SCP = (DWORD)GetProcAddress(LoadLibraryW(L"user32.dll")), "SetCursorPos") + 5;


ascii:
Code:

DWORD SCP = (DWORD)GetProcAddress(LoadLibraryA("user32.dll")), "SetCursorPos") + 5;


and VC++ express! nice choice, I have the express edition too and its all you need. Remember winners don't do warez! Very Happy

@BirdsEye: yes you do need to bypass SetCursorPos because it is hooked, and doesn't work if you try to call it.

lol, this one you should've figured out. think about what its telling you. GetProcAddress DOESN'T take 1 parameter. That means your only giving it 1 parameter. So take a look at whats screwing it up.

your closing it off with )

remove it

so

Code:

DWORD SCP = (DWORD)GetProcAddress(LoadLibraryW(L"user32.dll")), "SetCursorPos") + 5;


to

Code:

DWORD SCP = (DWORD)GetProcAddress(LoadLibraryW(L"user32.dll"), "SetCursorPos") + 5;


and actually its not your fault either, BirdsEye posted it like that with the extra parenthesis. And I didn't catch it. But that's why your compiler gives you the error so you can fix your mistake if you didn't catch it yourself.
