写这个游戏已经有一段时间了,一直在实现各种新功能,从最开始的地图上只有坦克,发子弹还是一个大问题到现在可以两个人一起玩,还是花了不少心思的,现在坦克的速度更快,电脑坦克也不会撞墙.虽然游戏性没有经典坦克大战那么强,但是还是可以用来休闲娱乐一下,这个用了很多最近学到的新知识,模仿俄罗斯方块,还有一些小技巧,比如可以同时按触发多个按键事件,对子弹的处理等.
左边的坦克用W D S A控制移动,H发射子弹,每次最多出现5颗子弹,右边的坦克用上下左右箭头控制移动,L键发射子弹,互不干扰.Q键可以直接退出游戏,游戏结束后按Y键可以继续游戏.为了结构清晰游戏分为Mywar Shoot Tanks 3个类.
（第二次用插入代码，之前一直都不懂这功能，我奥特蛋了 (*^__^*) 嘻嘻……）
