帮我写一个飞机大战的python代码

好的，以下是一个简单的飞机大战的 Python 代码：

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/player.png")
player_rect = player_img.get_rect()
player_rect.centerx = screen_width // 2
player_rect.bottom = screen_height - 10

# 加载敌机图片
enemy_img = pygame.image.load("images/enemy.png")

# 设置字体
font = pygame.font.SysFont(None, 48)

# 设置游戏时钟
clock = pygame.time.Clock()

# 设置游戏分数
score = 0

# 定义敌机类
class Enemy(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = enemy_img
        self.rect = self.image.get_rect()
        self.rect.x = random.randint(0, screen_width - self.rect.width)
        self.rect.y = random.randint(-100, -self.rect.height)
        self.speed = random.randint(1, 3)

    def update(self):
        self.rect.y += self.speed
        if self.rect.top > screen_height:
            self.kill()

# 创建敌机组
enemy_group = pygame.sprite.Group()

# 创建玩家飞机精灵
player = pygame.sprite.Sprite()
player.image = player_img
player.rect = player_rect

# 创建所有精灵组
all_sprites_group = pygame.sprite.Group()
all_sprites_group.add(player)

# 游戏循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 绘制背景
    screen.blit(background, (0, 0))

    # 更新玩家飞机位置
    player.rect.centerx = pygame.mouse.get_pos()[0]
    if player.rect.left < 0:
        player.rect.left = 0
    elif player.rect.right > screen_width:
        player.rect.right = screen_width

    # 创建敌机
    if random.randint(1, 60) == 1:
        enemy = Enemy()
        enemy_group.add(enemy)
        all_sprites_group.add(enemy)

    # 更新敌机位置
    enemy_group.update()

    # 绘制所有精灵
    all_sprites_group.draw(screen)

    # 检测玩家飞机和敌机的碰撞
    if pygame.sprite.spritecollide(player, enemy_group, True):
        running = False

    # 绘制分数
    score_text = font.render("Score: " + str(score), True, (255, 255, 255))
    screen.blit(score_text, (10, 10))

    # 更新屏幕
    pygame.display.update()

    # 设置游戏帧率
    clock.tick(60)

# 退出 Pygame
pygame.quit()

希望这个代码能够帮到你！
