python飞机大战小游戏

以下是Python语言实现的飞机大战小游戏的基本功能：

# 导入必要的模块
import pygame
import random

# 初始化pygame
pygame.init()

# 设置游戏窗口大小
screen_width = 480
screen_height = 700
screen = pygame.display.set_mode((screen_width, screen_height))

# 设置游戏标题
pygame.display.set_caption("飞机大战")

# 加载背景图片
background = pygame.image.load("images/background.png")

# 加载玩家飞机图片
player_img = pygame.image.load("images/me1.png")

# 加载敌方飞机图片
enemy_imgs = [
    pygame.image.load("images/enemy1.png"),
    pygame.image.load("images/enemy2.png"),
    pygame.image.load("images/enemy3.png")
]

# 加载子弹图片
bullet_img = pygame.image.load("images/bullet1.png")

# 加载游戏音效
bullet_sound = pygame.mixer.Sound("sounds/bullet.wav")
enemy_down_sound = pygame.mixer.Sound("sounds/enemy_down.wav")
game_over_sound = pygame.mixer.Sound("sounds/game_over.wav")
