用python使用pygame写飞机大战的小游戏

好的，我可以帮你回答这个问题。首先需要安装pygame模块，可以在命令行中输入 pip install pygame 进行安装。然后，使用下面的示例代码，可以实现一个基础版的飞机大战游戏：

import pygame
import random

# 初始化pygame
pygame.init()

# 设置游戏界面大小、背景颜色
screen_width = 480
screen_height = 700
bg_color = pygame.Color('gray')

# 创建游戏窗口
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
bg = 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(center=(screen_width//2, screen_height-100))

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

# 加载敌机图片
enemy_img1 = pygame.image.load('images/enemy1.png')
enemy_img2 = pygame.image.load('images/enemy2.png')
enemy_img3 = pygame.image.load('images/enemy3.png')
enemy_imgs = [enemy_img1, enemy_img2, enemy_img3]

# 飞机、子弹及敌机列表
player = pygame.sprite.GroupSingle()
player.add(pygame.sprite.Sprite())
player.sprite.image = player_img
player.sprite.rect = player_rect

bullets = pygame.sprite.Group()

enemies = pygame.sprite.Group()

# 创建敌机
for i in range(6):
    enemy = pygame.sprite.Sprite()
    enemy.image = random.choice(enemy_imgs)
    enemy.rect = enemy.image.get_rect(
        center=(random.randint(30, screen_width-30), random.randint(-100, -50)))
    enemies.add(enemy)

# 设置帧率
clock = pygame.time.Clock()

# 定义游戏循环
while True:
    # 事件检测
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

    # 玩家移动操作
    keys = pygame.key.get_pressed()
    if keys[pygame.K_UP]:
        player.sprite.rect.move_ip(0, -5)
    if keys[pygame.K_DOWN]:
        player.sprite.rect.move_ip(0, 5)
    if keys[pygame.K_LEFT]:
        player.sprite.rect.move_ip(-5, 0)
    if keys[pygame.K_RIGHT]:
        player.sprite.rect.move_ip(5, 0)

    # 玩家边界限制
    if player.sprite.rect.left <= 0:
        player.sprite.rect.left = 0
    if player.sprite.rect.right >= screen_width:
        player.sprite.rect.right = screen_width
    if player.sprite.rect.top <= 0:
        player.sprite.rect.top = 0
    if player.sprite.rect.bottom >= screen_height:
        player.sprite.rect.bottom = screen_height

    # 子弹发射操作
    if keys[pygame.K_SPACE]:
        bullet = pygame.sprite.Sprite()
        bullet.image = bullet_img
        bullet.rect = bullet.image.get_rect(center=player.sprite.rect.midtop)
        bullets.add(bullet)

    # 子弹移动
    for bullet in bullets:
        bullet.rect.move_ip(0, -5)
        if bullet.rect.bottom <= 0:
            bullets.remove(bullet)

    # 敌机移动
    for enemy in enemies:
        enemy.rect.move_ip(0, 3)
        if enemy.rect.top >= screen_height:
            enemy.kill()
            enemy = pygame.sprite.Sprite()
            enemy.image = random.choice(enemy_imgs)
            enemy.rect = enemy.image.get_rect(
                center=(random.randint(30, screen_width-30), random.randint(-100, -50)))
            enemies.add(enemy)

    # 子弹击中敌机
    for enemy in pygame.sprite.groupcollide(enemies, bullets, True, True):
        enemy = pygame.sprite.Sprite()
        enemy.image = random.choice(enemy_imgs)
        enemy.rect = enemy.image.get_rect(
            center=(random.randint(30, screen_width-30), random.randint(-100, -50)))
        enemies.add(enemy)

    # 玩家与敌机碰撞检测
    if pygame.sprite.spritecollide(player.sprite, enemies, True):
        pygame.quit()
        exit()

    # 游戏界面显示
    screen.blit(bg, (0,0))
    player.draw(screen)
    bullets.draw(screen)
    enemies.draw(screen)
    pygame.display.flip()

    # 设置帧率
    clock.tick(60)

希望以上代码对你有所帮助！
