用Python写一个飞机大战游戏

好的，下面是一个简单的飞机大战游戏的Python代码：

import pygame
import random

# 初始化Pygame
pygame.init()

# 设置窗口大小和标题
WIDTH, HEIGHT = 480, 700
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("飞机大战")

# 加载图像
bg_img = 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()
bullet_img = pygame.image.load("images/bullet.png").convert_alpha()

# 设置颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)

# 设置字体
font = pygame.font.SysFont(None, 30)

# 定义游戏对象类
class GameObject(pygame.sprite.Sprite):
    def __init__(self, img, x, y, speed):
        pygame.sprite.Sprite.__init__(self)
        self.image = img
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y
        self.speed = speed

    def update(self):
        self.rect.y += self.speed

# 定义玩家类
class Player(GameObject):
    def __init__(self, img, x, y, speed):
        super().__init__(img, x, y, speed)
        self.score = 0

    def shoot(self):
        bullet = Bullet(bullet_img, self.rect.centerx, self.rect.top, -10)
        all_sprites.add(bullet)
        bullets.add(bullet)

# 定义敌人类
class Enemy(GameObject):
    def __init__(self, img, x, y, speed):
        super().__init__(img, x, y, speed)

    def update(self):
        self.rect.y += self.speed
        if self.rect.top > HEIGHT:
            self.rect.x = random.randrange(WIDTH - self.rect.width)
            self.rect.y = random.randrange(-100, -40)
            self.speed = random.randrange(1, 8)
            player.score += 1

# 定义子弹类
class Bullet(GameObject):
    def __init__(self, img, x, y, speed):
        super().__init__(img, x, y, speed)

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

# 创建游戏对象
player = Player(player_img, WIDTH/2, HEIGHT-100, 0)
enemies = pygame.sprite.Group()
bullets = pygame.sprite.Group()
all_sprites = pygame.sprite.Group()
all_sprites.add(player)

# 设置敌人数量
NUM_ENEMIES = 10

# 创建敌人
for i in range(NUM_ENEMIES):
    enemy = Enemy(enemy_img, random.randrange(WIDTH - enemy_img.get_width()), random.randrange(-1500, -100), random.randrange(1, 8))
    enemies.add(enemy)
    all_sprites.add(enemy)

# 创建时钟对象
clock = pygame.time.Clock()

# 游戏循环
running = True
while running:
    # 设置帧率
    clock.tick(60)

    # 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_SPACE:
                player.shoot()

    # 移动玩家
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        player.rect.x -= 5
    if keys[pygame.K_RIGHT]:
        player.rect.x += 5

    # 更新游戏对象
    all_sprites.update()

    # 检测敌人和子弹是否碰撞
    hits = pygame.sprite.groupcollide(enemies, bullets, True, True)
    for hit in hits:
        enemy = Enemy(enemy_img, random.randrange(WIDTH - enemy_img.get_width()), random.randrange(-1500, -100), random.randrange(1, 8))
        enemies.add(enemy)
        all_sprites.add(enemy)

    # 检测玩家和敌人是否碰撞
    hits = pygame.sprite.spritecollide(player, enemies, False)
    if hits:
        running = False

    # 绘制游戏界面
    screen.blit(bg_img, (0, 0))
    all_sprites.draw(screen)
    score_text = font.render("Score: {}".format(player.score), True, WHITE)
    screen.blit(score_text, (10, 10))
    pygame.display.update()

# 退出Pygame
pygame.quit()

你可以将上述代码保存在一个名为“plane_game.py”的文件中，并在与图片文件夹同一目录下新建一个名为“images”的文件夹，将游戏所需的图片文件放入其中，然后运行该文件，即可开始游戏。
