一个C语言编写的坦克大战游戏

       在VC6.0平台下运用一个EasyX的图形库，用C语言编写了一个坦克大战的小游戏，代码和算法都是我自己源生的。文章的两幅配图，分别展示了游戏的开始选择界面和正在游戏界面。这个小游戏，具有游戏背景音乐，音乐是我在网上搜索到的坦克大战的音乐文件，然后将音乐的播放加入到代码的编写当中。另外游戏中坦克可以接道具，接道具后，会有相应的状态效应。由于利用的是EasyX的简单画图函数，因此整个界面的图形不是很友好，另外有的地方图片是读取的磁盘图片文件到内存中，然后显示在游戏界面中的。整个代码有1900多行，由于只是业余写来娱乐的，因此代码里面应该有不少位子存在冗余。欢迎有兴趣的朋友，对相关代码进行提出修改意见。
