实现的功能有：
1.难度变更，根据玩家击杀的敌方坦克数量和获得的分数，增加场上的敌方坦克数量
2.血条显示，玩家坦克每击杀一个敌方坦克获得一个生命标记，没受到一次攻击掉落一个生命标记，初始标记20个
3.敌方坦克的随机生成，敌方坦克3种类型，一种血厚防高移速慢黄色坦克，一种血防平衡移速适中白色坦克，一种血薄防低移速快原谅坦克，随机生成不同类型
4.空格键发射子弹，方向键控制方向，未设置连发，按一次空格射击一次
5.碰撞判定，圆的相交判定
6.允许穿模，即坦克相撞不产生伤害，不然难度太高

有兴趣的可以拿去尝试看看能打到多少分，每个py文件独立一个模块，资源图：

enemy：（enemy_creat.gif 是我自己复制了一个敌方坦克图然后用ps直接扣空成一张白图，并不是白色，而是什么都没有，拿来作为初始化每一个敌军坦克的初始显示图，因为一移动就会自动变换成对应类型的模样，刚开始创建打印应该什么都没有）
