模仿写了个win32雷霆战机游戏，加载不了图片
就是消息循环用while(msg.message != WM_QUIT) if (PeekMessage(&msg, 0, 0, 0, PM_REMOVE)) {TranslateMessage(&msg); DispatchMessage(&msg);} 敌军图片一加载出来就消失，子弹正常，当用while (GetMessage(&msg, nullptr, 0, 0)) if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)) {TranslateMessage(&msg); DispatchMessage(&msg);} //这是自动生成的代码，上面那是别人写好的程序用的。时就加载不出敌军的图片但会判断撞没撞。这是怎么回事啊，我估计是消息循环的原因但我不大懂#include "stdafx.h"
