在Win32 API中的游戏循环 [英] Game loop in Win32 API

问题描述

我在win32 GDI中创建游戏马里奥。我已经实现了游戏的新循环：

I'm creating game mario like in win32 GDI . I've implemented the new loop for game :

PeekMessage(&msg,NULL,0,0,PM_NOREMOVE);

while (msg.message!=WM_QUIT)
{
    if (PeekMessage(&msg,NULL,0,0,PM_REMOVE)) {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    else // No message to do
    {
        gGameMain->GameLoop();  
    }
}

但是我的游戏只是运行直到我按Ctrl + Alt + Del（鼠标光标滚动）。

But my game just running until I press Ctrl + Alt + Del ( mouse cursor is rolling ).

推荐答案

我一直使用类似的东西：

I've always been using something like that:

    MSG msg;
    while (running){
        if (PeekMessage(&msg, hWnd, 0, 0, PM_REMOVE)){
            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }
        else
            try{
                onIdle();
            }
            catch(std::exception& e){
                onError(e.what());
                close();
            }
    }

onIdle是实际的游戏lopp实现，onError错误处理程序（将错误描述作为参数），而running是全局bool变量或类成员。将running设置为false会关闭游戏。

onIdle is actual game lopp implementation, onError() is an error handler (takes error description as argument), and "running" is either a global bool variable or a class member. Setting "running" to false shuts down the game.
