以下是看了变速齿轮原理后编写的！暂时碰到一些问题，还请高人指点！
小弟hook了几个函数，分别是timeGetTime GetTickCount QueryPerformanceCounter 和 SetTimer
先是在main()函数中提取了4个函数真正的返回值！
然后当hook到这4个函数时就用下面是函数替换且返回假返回值：
//GetTickCount()
DWORD WINAPI my_GetTickCount()
{
DWORD dwRet;
dwRet = ((PFN_GetTickCount)(PROC) g_GetTickCount)();
dwRet = DWORD(DOUBLE(dwRet - g_dwFirstOfGetTickCountRet) * g_dMultiple);
return dwRet;
}
//SetTimer()
UINT WINAPI my_SetTimer(HWND hWnd, UINT nIDEvent, UINT uElapse, TIMERPROC lpTimerFunc)
{
UINT uRet, uMyElapse = (UINT)((DOUBLE)uElapse / g_dMultiple);
uRet = ((PFN_SetTimer)(PROC) g_SetTimer)(hWnd, nIDEvent, uMyElapse, lpTimerFunc);
return uRet;
}
//QueryPerformanceCounter();
BOOL WINAPI my_QueryPerformanceCounter(LARGE_INTEGER *lpPerformanceCount)
{
BOOL fRet;
fRet = ((PFN_QueryPerformanceCounter)(PROC) g_QueryPerformanceCounter)(lpPerformanceCount);
if(fRet)lpPerformanceCount->QuadPart = LONGLONG(DOUBLE(lpPerformanceCount->QuadPart - g_liFirstOfQueryPerformanceCounter.QuadPart) * g_dMultiple);
return fRet;
}
MMRESULT WINAPI my_timeSetEvent(UINT uDelay, UINT uResolution, LPTIMECALLBACK lpTimeProc, DWORD dwUser, UINT fuEvent)
{
MMRESULT Ret;
UINT uMyDelay = (UINT)((DOUBLE)uDelay / g_dMultiple);
Ret = ((PFN_timeSetEvent)(PROC) g_timeSetEvent)(uMyDelay, uResolution, lpTimeProc, dwUser, fuEvent);
return Ret;
}
我用自己的测试程序测试成功，但是在游戏中却无法起到加速作用，还请高手指点一二！
我只是不清楚，如果HOOK到了gettickcount函数后，替换函数应该如何修改返回值才能达到加速的效果呢？
