python实现飞机大战游戏

飞机大战游戏是一个经典的2D游戏，下面我给你提供一个基于Python的简单实现。本实现基于Pygame库，需要先安装Pygame。

import pygame
import random

pygame.init()

# 游戏窗口大小
WIDTH = 480
HEIGHT = 700

# 颜色定义
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)

# 初始化游戏窗口
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("飞机大战")

# 加载图片
background = pygame.image.load("background.png").convert()
player_img = pygame.image.load("player.png").convert()
player_mini_img = pygame.transform.scale(player_img, (25, 19))
player_mini_img.set_colorkey(BLACK)
enemy_img = pygame.image.load("enemy.png").convert()
bullet_img = pygame.image.load("bullet.png").convert()

# 加载声音
shoot_sound = pygame.mixer.Sound("shoot.wav")
expl_sound = pygame.mixer.Sound("explosion.wav")
pygame.mixer.music.load("background.ogg")
pygame.mixer.music.set_volume(0.2)

# 玩家类

在运行游戏之前，需要准备好游戏所需的图片和声音文件，并与代码中的文件名相对应。游戏所需的资源可以从互联网上搜索并下载。
