我想创建一个简单的游戏循环。我正在考虑这两个版本：

v.1：

while (continueRunning) {

        PeekMessage(&msg, 0, 0, 0, PM_REMOVE);

        TranslateMessage(&msg);
        DispatchMessage(&msg);

        if (WM_QUIT == msg.message) {
            continueRunning = false;
        }

        // run the game logic

    }

和 v.2：

while(continueRunning)
{
    // peek for messages
    while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);

        if (msg.message == WM_QUIT)
            continueRunning = false;
    }

    // run the game logic
}

什么是更好的解决方案？是否需要有PeekMessage在while循环像在第二个例子？

我写了一个简单Win32 App的Visual Studio的2019对10场。在WinMain函数内的主消息循环中，我有：

while (Msg.message != WM_QUIT) {

    if (PeekMessage(&Msg, NULL, 0, 0, PM_REMOVE) > 0) {
        TranslateMessage(&Msg);
        DispatchMessage(&Msg);

        swprintf_s(msgbuf, _T("In the PeekMessage loop cnt: %d, msg: %d\n"), loop_cnt++, Msg.message);
        OutputDebugString(msgbuf);
    }
...
}

我得到以下输出：

In the PeekMessage loop cnt: 0, msg: 799
In the PeekMessage loop cnt: 1, msg: 49300
In the PeekMessage loop cnt: 2, msg: 96
In the PeekMessage loop cnt: 3, msg: 96
In the PeekMessage loop cnt: …
