这是一个纯javascript语言开发的射击类游戏，它的名字叫“打飞机”，主体开发了4个工作日，内部含有全部的代码。希望大家学习学习。运行这款游戏可以在IE8以上浏览器运行。运行时如果屏幕分辨率不兼容，你可以缩放到最佳显示效果。
简介：
这个游戏是我在去年上自习课时闲着无聊做的一个射击类小游戏，总共花个4个工作日才完成，为了游戏的效率，做了很多优化，目前在IE8以上浏览器能够流畅运行，运行时如果屏幕分辨率不兼容，你可以缩放到最佳显示效果。大家可以学习学习，有不足的地方你们可以自己改改。

代码说明：
这个游戏是基于HTML4开发的，所以兼容性也挺不错的，电脑配置稍微高些就可以流畅玩耍了。下面介绍下相关代码。
