pygame写飞机大战

好的，这里是一个简单的Pygame飞机大战游戏示例：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 创建游戏窗口
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").convert()

# 加载游戏音效
pygame.mixer.music.load("sound/game_music.ogg")
pygame.mixer.music.set_volume(0.2)
pygame.mixer.music.play(-1)

bullet_sound = pygame.mixer.Sound("sound/bullet.wav")
bullet_sound.set_volume(0.2)

enemy_down_sound = pygame.mixer.Sound("sound/enemy_down.wav")
enemy_down_sound.set_volume(0.2)

game_over_sound = pygame.mixer.Sound("sound/game_over.wav")
game_over_sound.set_volume(0.2)

# 加载玩家飞机图片
player_image = pygame.image.load("images/player.png").convert_alpha()

# 加载子弹图片
bullet_image = pygame.image.load("images/bullet.png").convert_alpha()

# 加载敌机图片
enemy_images = [
    pygame.image.load("images/enemy1.png").convert_alpha(),
    pygame.image.load("images/enemy2.png").convert_alpha(),
    pygame.image.load("images/enemy3.png").convert_alpha(),
]

# 定义玩家飞机类
class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = player_image
        self.rect = self.image.get_rect()
        self.rect.midbottom = (screen_width // 2, screen_height - 30)
        self.speed = 8
        self.bullets = pygame.sprite.Group()

    def update(self, keys):
        if keys[pygame.K_LEFT] and self.rect.left > 0:
            self.rect.x -= self.speed
        if keys[pygame.K_RIGHT] and self.rect.right < screen_width:
            self.rect.x += self.speed

    def shoot(self):
        bullet = Bullet(self.rect.centerx, self.rect.top)
        self.bullets.add(bullet)
        bullet_sound.play()

# 定义子弹类
class Bullet(pygame.sprite.Sprite):
    def __init__(self, x, y):
        super().__init__()
        self.image = bullet_image
        self.rect = self.image.get_rect()
        self.rect.centerx = x
        self.rect.bottom = y
        self.speed = -10

    def update(self):
        self.rect.y += self.speed
        if self.rect.bottom < 0:
            self.kill()

# 定义敌机类
class Enemy(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = random.choice(enemy_images)
        self.rect = self.image.get_rect()
        self.rect.x = random.randint(0, screen_width - self.rect.width)
        self.rect.y = random.randint(-200, -50)
        self.speed = random.randint(1, 4)
        self.health = 1

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

# 创建游戏对象
player = Player()
enemies = pygame.sprite.Group()
all_sprites = pygame.sprite.Group()
all_sprites.add(player)

# 设置游戏主循环
clock = pygame.time.Clock()
score = 0
game_over = False

while not game_over:
    clock.tick(60)

    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True

    # 检测玩家按键
    keys = pygame.key.get_pressed()
    if keys[pygame.K_SPACE]:
        player.shoot()

    # 更新玩家和子弹
    player.update(keys)
    player.bullets.update()

    # 检测子弹和敌机碰撞
    for bullet in player.bullets:
        enemies_hit = pygame.sprite.spritecollide(bullet, enemies, True)
        for enemy in enemies_hit:
            enemy_down_sound.play()
            score += 100
            bullet.kill()

    # 更新敌机
    if random.randint(1, 30) == 1:
        enemy = Enemy()
        enemies.add(enemy)
        all_sprites.add(enemy)
    enemies.update()

    # 检测玩家与敌机碰撞
    if pygame.sprite.spritecollide(player, enemies, True):
        game_over_sound.play()
        game_over = True

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

    # 显示得分
    font = pygame.font.SysFont(None, 36)
    score_text = font.render("得分: {}".format(score), True, (255, 255, 255))
    screen.blit(score_text, (10, 10))

    # 更新屏幕
    pygame.display.update()

# 游戏结束
pygame.quit()

你可以在代码中看到，程序使用了 Pygame 绘图模块来创建游戏窗口、加载图片和播放音效。游戏中有三个主要的类：Player、Bullet和Enemy。其中，Player类表示玩家飞机，Bullet类表示子弹，Enemy类表示敌机。游戏主循环中，程序不断更新玩家和子弹位置，检测子弹和敌机碰撞，更新敌机位置，检测玩家与敌机碰撞，绘制游戏界面，并在游戏结束时退出 Pygame。
