python pygame实现滚动横版射击游戏城市之战实现滚动横版射击游戏城市之战
主要为大家详细介绍了python pygame实现滚动横版射击游戏城市之战，文中示例代码介绍的非常详细，具有一定的参考
价值，感兴趣的小伙伴们可以参考一下
pygame城市之战横版射击游戏,按上下左右方向箭头操作飞机。这是一个横板射击小游戏，在黑夜的城市上空，你将要操作一架飞机去射
击敌机,爆炸效果还不错。
在游戏中定义了滚动的背景类，定义了飞机类Plane，定义了子弹类，敌机类，爆炸类等，是学习Pygame和面向对象编程的好例子。
代码：

pygame.sprite.Sprite.__init__(self)
