用python写一个飞机大战

好的，下面是一个简单的飞机大战游戏的代码实现。请注意，此代码仅用于学习和参考目的，可能存在一些不足之处。

import pygame
import random

# 初始化pygame
pygame.init()

# 创建游戏窗口
win_width = 480
win_height = 700
window = pygame.display.set_mode((win_width, win_height))

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

# 加载游戏资源

# 设置游戏音效

bg_music = pygame.mixer.music.load("sounds/bg_music.mp3")
pygame.mixer.music.play(-1)

# 设置游戏字体
font_score = pygame.font.SysFont("Arial", 30, True)
font_gameover = pygame.font.SysFont("Arial", 60, True)

# 设置游戏变量
score = 0

# 定义游戏角色类

# 创建角色和子弹

# 定义游戏结束函数

    elif keys[pygame.K_RIGHT]:
        player.move_right()
    
    # 更新游戏窗口
    pygame.display.update()

这里只是一个简单的实现，你可以根据自己的需求和想法进行扩展和优化。
