基于对面向对象编程的思想完成简单的坦克大战游戏。主要目的锻炼面相对象编程思想
同样的在使用python进行游戏编写时需要安装pygame模块
安装方法：
pycharm安装方式：File --> setting
游戏中的主要对象有：
坦克父类：BaseTank
我方坦克：HeroTank
敌方坦克：EnemyTank
子弹类：Bullet
爆炸类：Explode
墙类：Wall
主进程：MainGame
定义一个精灵类：
# 定义一个精灵类 class BaseItem(Sprite): def __init__(self, color, width, height): # Call the parent class (Sprite) constructor pygame.sprite.Sprite.__init__(self)
坦克父类：
# 坦克父类
