写一个python飞机游戏代码

好的，下面是一个简单的Python飞机游戏代码示例：

import pygame
import random

# 初始化pygame
pygame.init()

# 设置游戏窗口大小和标题
screen_width = 480
screen_height = 700
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("飞机大战")

# 加载游戏背景图和飞机图片
background = pygame.image.load("images/background.png").convert()
player_img = pygame.image.load("images/player.png").convert_alpha()
enemy_img = pygame.image.load("images/enemy.png").convert_alpha()

# 设置游戏时钟和帧率
clock = pygame.time.Clock()
FPS = 60

# 定义玩家飞机类
class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = player_img
        self.rect = self.image.get_rect()
        self.rect.centerx = screen_width // 2
        self.rect.bottom = screen_height - 10
        self.speed_x = 0
        self.speed_y = 0

    def update(self):
        self.rect.x += self.speed_x
        self.rect.y += self.speed_y
        if self.rect.left < 0:
            self.rect.left = 0
        elif self.rect.right > screen_width:
            self.rect.right = screen_width
        elif self.rect.top < 0:
            self.rect.top = 0
        elif self.rect.bottom > screen_height:
            self.rect.bottom = screen_height

# 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, -40)
        self.speed_y = random.randint(1, 3)

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

# 创建玩家飞机和敌机精灵组
all_sprites = pygame.sprite.Group()
enemies = pygame.sprite.Group()
player = Player()
all_sprites.add(player)

# 游戏主循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                player.speed_x = -5
            elif event.key == pygame.K_RIGHT:
                player.speed_x = 5
            elif event.key == pygame.K_UP:
                player.speed_y = -5
            elif event.key == pygame.K_DOWN:
                player.speed_y = 5
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                player.speed_x = 0
            elif event.key == pygame.K_UP or event.key == pygame.K_DOWN:
                player.speed_y = 0

    # 生成敌机
    if random.randint(1, 60) == 1:
        enemy = Enemy()
        all_sprites.add(enemy)
        enemies.add(enemy)

    # 更新精灵组
    all_sprites.update()

    # 检测敌机和玩家飞机的碰撞
    hits = pygame.sprite.spritecollide(player, enemies, False)
    if hits:
        running = False

    # 绘制游戏界面
    screen.blit(background, (0, 0))
    all_sprites.draw(screen)

    # 刷新屏幕
    pygame.display.flip()

    # 控制帧率
    clock.tick(FPS)

# 退出游戏
pygame.quit()

这个游戏会在窗口中显示一个玩家飞机和一些敌机，玩家可以使用箭头键控制飞机移动，避免和敌机撞击。当玩家撞到敌机时，游戏结束。
