python基于pygame实现飞机大作战小游戏

基于pygame的飞机大作战小游戏，适合新手，不能直接运行，只能在命令行进入当前游戏目录，输入python game.py才能够运行，尚不知道是什么原因。

游戏截图如下，我们用黄色的圆圈代表敌机：

代码如下

import pygame,sys,time,random,math

def init():
pygame.init()
size = width, height =600,600
screen =pygame.display.set_mode(size)
plx=270
ply=528
beijing =pygame.image.load("beijing.jpg")
main_role =pygame.image.load("main_role.jpg")
font=pygame.font.SysFont("arial",60)

return screen,[plx,ply],main_role,beijing,font

def mainloop(screen,pl,main_role,beijing,shots,ms,ecs): #每刷新一次,调用一次
for event in pygame.event.get():
