#1. 初始化 pygame
pygame.init()#2. 设置游戏界面大小、背景图片及标题
# 游戏界面像素大小
screen = pygame.display.set_mode((480, 800))# 游戏界面标题
pygame.display.set_caption('飞机大战')# 背景图
background = pygame.image.load('resources/image/background.png').convert()# Game Over 的背景图
game_over = pygame.image.load('resources/image/gameover.png')# 飞机图片
plane_img = pygame.image.load('resources/image/shoot.png')# 截取玩家飞机图片
player = plane_img.subsurface(pygame.Rect(0, 99, 102, 126))#3. 游戏主循环内需要处理游戏界面的初始化、更新及退出
