干什么的？走迷宫？

还有，代码中混杂英语和中文注译，我怀疑英文部分不是你原创

hzzh · 发表于 2004-4-9 16:15:00

楼主牛，我一小时只能读懂程序结构和实现方法。
不过void Delay(long time) 函数有问题，把CPU时间都白白吃光了,应该改成Sleep()

yzhlinux · 发表于 2004-4-9 19:35:00

不是吧，这样的程序都叫"最"简单了啊，我看来都是在写白痴程序了

hays2002 · 发表于 2004-4-10 15:23:00

绝对原创。。。。。。void Delay(long time) 函数的功能就是用来延时的。。。。。。

延时还有比Sleep(int)更好的吗？不浪费cpy啊，你用循环来拖延真是大胆创新啊

循环延时有是有的，不过会造成不同配置上的延时的不一致

再问一次，这个游戏到底是游的什么？？？

void Delay(long time) 确实可以用来延时，而且延时也比较准，但是Delay()是用CPU满负荷运行换来的。
在你的程序中把Delay(long time) 换成 Sleep(long time) ，然后看看CPU的负荷就知道了。
按理说能够在一小时内编出这个游戏的人不会不知道考虑CPU效率的，除非你喜欢让CPU发烧。

timeSetEvent 这个winAPI来定时不是更好马，毫秒精度应该也可以了
另外好像是用mfc还是什么的，mfc总是把我盟在雇里

楼主的编码风格真好，一会用C＋＋的风格，一会儿用C的风格，不知道楼主是不是学这两种语言的时候走火入魔了。
