pygame介绍
Pygame被设计用来写游戏的python模块集合，基于SDL库开发。使用python可以导入pygame来开发具有全部特性的游戏和多媒体软件，Pygame是极度轻便的并且可以运行在几乎所有的平台和操作系统上。1. 导入依赖 & 通用配置

1 2* pygame.sprite模块，官方文档上说这个模块是轻量级的，在游戏开发中也未必要使用。3* sprite翻译为精灵，在游戏动画一般是指一个独立运动的画面元素，在pygame中，4就可以是一个带有图像（Surface）和大小位置（Rect）的对象。5* pygame.sprite.Sprite是pygame精灵的基类，一般来说，需要写一个自己的精灵类继承一下它然后加入自己的代码。6 7class BaseItem(pygame.sprite.Sprite):8 def __init__(self):9 super().__init__()
