Setting mouse position in FPS games C++

int x = 0;
int y = 0;
INPUT inputm;
int count = dis;
for(int i = 0; i <= count; i++){
    inputm.mi.dx = (x-i)*(65536.0f/GetSystemMetrics(SM_CXSCREEN));//x being coord in pixels
    inputm.mi.dy = y*(65536.0f/GetSystemMetrics(SM_CYSCREEN));//y being coord in pixels
    inputm.mi.dwFlags = MOUSEEVENTF_MOVE;
    inputm.type = INPUT_MOUSE;
    SendInput(1, &inputm, sizeof(inputm));
    Sleep(1);
}

Try using SendInput with relative mouse motion, so without the MOUSEEVENTF_ABSOLUTE flag in the MOUSEINPUT struct.
