写一个飞机大战的游戏代码

好的，我可以尝试为您提供一个基于 Python 语言的飞机大战游戏代码，以下是代码实现：

import pygame
import random

# 设置屏幕宽高
SCREEN_WIDTH = 480
SCREEN_HEIGHT = 800

# 创建游戏窗口
pygame.init()
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption("飞机大战")

# 加载游戏图片
background_img = pygame.image.load("images/background.png").convert()
player_img = pygame.image.load("images/player.png").convert_alpha()
bullet_img = pygame.image.load("images/bullet.png").convert_alpha()
enemy_img = pygame.image.load("images/enemy.png").convert_alpha()

# 创建玩家飞机类
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 = 5

    def update(self):
        keys_pressed = pygame.key.get_pressed()
        if keys_pressed[pygame.K_LEFT] and self.rect.left > 0:
            self.rect.x -= self.speed
        elif keys_pressed[pygame.K_RIGHT] and self.rect.right < SCREEN_WIDTH:
            self.rect.x += self.speed
        if keys_pressed[pygame.K_UP] and self.rect.top > 0:
            self.rect.y -= self.speed
        elif keys_pressed[pygame.K_DOWN] and self.rect.bottom < SCREEN_HEIGHT:
            self.rect.y += self.speed

    def fire(self):
        bullet = Bullet(self.rect.centerx, self.rect.top)
        all_sprites.add(bullet)
        bullets.add(bullet)

# 创建子弹类
class Bullet(pygame.sprite.Sprite):
    def __init__(self, x, y):
        super().__init__()
        self.image = bullet_img
        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()

# 创建敌机类
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 = random.randint(1, 4)

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

# 创建精灵组
all_sprites = pygame.sprite.Group()
player = Player()
bullets = pygame.sprite.Group()
enemies = pygame.sprite.Group()

all_sprites.add(player)

# 设置游戏循环
running = True
clock = pygame.time.Clock()

while running:
    clock.tick(60)

    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.fire()

    # 添加敌机
    if random.randint(0, 100) < 2:
        enemy = Enemy()
        all_sprites.add(enemy)
        enemies.add(enemy)

    # 检测子弹是否击中敌机
    hits = pygame.sprite.groupcollide(enemies, bullets, True, True)

    # 更新精灵组
    all_sprites.update()

    # 绘制游戏背景
    screen.blit(background_img, (0, 0))

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

    # 更新屏幕显示
    pygame.display.flip()

pygame.quit()

您可以将代码保存为 `plane.py` 文件，然后在终端中运行 `python plane.py` 命令启动游戏。祝您游戏愉快！
