用python写一个飞机大战的游戏

好的，下面是一个简单的飞机大战游戏的代码，使用Python的Pygame库实现：

import pygame
import random

# 初始化 Pygame 库
pygame.init()

# 设置游戏窗口的尺寸
screen_width, screen_height = 480, 700
screen = pygame.display.set_mode((screen_width, screen_height))

# 设置游戏窗口标题和图标
pygame.display.set_caption("飞机大战")
icon = pygame.image.load("icon.png")
pygame.display.set_icon(icon)

# 加载游戏所需的图像资源
background = pygame.image.load("background.png")
player_img = pygame.image.load("player.png")
bullet_img = pygame.image.load("bullet.png")
enemy_img = pygame.image.load("enemy.png")
explosion_imgs = [pygame.image.load(f"explosion{i}.png") for i in range(1, 6)]

# 设置游戏的帧率和时钟对象
FPS = 60
clock = pygame.time.Clock()

# 定义游戏角色的类
class Sprite:
    def __init__(self, x, y, img):
        self.x = x
        self.y = y
        self.img = img
        self.rect = self.img.get_rect()
        self.rect.center = (self.x, self.y)

    def draw(self):
        screen.blit(self.img, self.rect)

# 定义玩家角色的类
class Player(Sprite):
    def __init__(self):
        super().__init__(screen_width // 2, screen_height - 100, player_img)
        self.speed = 5
        self.bullets = []
        self.health = 3

    def move(self, dir):
        if dir == "left":
            self.x -= self.speed
        elif dir == "right":
            self.x += self.speed

        if self.x < 0:
            self.x = 0
        elif self.x > screen_width:
            self.x = screen_width

        self.rect.center = (self.x, self.y)

    def shoot(self):
        bullet = Bullet(self.x, self.y)
        self.bullets.append(bullet)

    def check_collision(self, enemies):
        for enemy in enemies:
            if pygame.sprite.collide_rect(enemy, self):
                self.health -= 1
                if self.health <= 0:
                    self.kill()
                enemy.kill()

    def kill(self):
        explosion = Explosion(self.x, self.y)
        explosions.append(explosion)
        self.health = 0

# 定义子弹角色的类
class Bullet(Sprite):
    def __init__(self, x, y):
        super().__init__(x, y, bullet_img)
        self.speed = -10

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

# 定义敌人角色的类
class Enemy(Sprite):
    def __init__(self):
        x = random.randint(0, screen_width)
        y = -50
        super().__init__(x, y, enemy_img)
        self.speed = random.randint(1, 5)

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

# 定义爆炸效果角色的类
class Explosion(Sprite):
    def __init__(self, x, y):
        super().__init__(x, y, explosion_imgs[0])
        self.idx = 0
        self.timer = 0

    def update(self):
        self.timer += 1
        if self.timer >= 5:
            self.idx += 1
            if self.idx >= len(explosion_imgs):
                self.kill()
            else:
                self.img = explosion_imgs[self.idx]
            self.timer = 0

# 创建玩家对象和敌人列表
player = Player()
enemies = pygame.sprite.Group()
explosions = pygame.sprite.Group()

# 游戏主循环
running = True
while running:
    # 处理游戏事件
    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.move("left")
            elif event.key == pygame.K_RIGHT:
                player.move("right")
            elif event.key == pygame.K_SPACE:
                player.shoot()

    # 更新游戏角色
    for bullet in player.bullets:
        bullet.update()
    player.bullets = [bullet for bullet in player.bullets if not bullet.is_dead()]

    if random.randint(1, 30) == 1:
        enemy = Enemy()
        enemies.add(enemy)

    for enemy in enemies:
        enemy.update()

    player.check_collision(enemies)

    for explosion in explosions:
        explosion.update()

    # 绘制游戏画面
    screen.blit(background, (0, 0))
    player.draw()
    for bullet in player.bullets:
        bullet.draw()
    enemies.draw(screen)
    explosions.draw(screen)

    # 更新游戏画面
    pygame.display.update()

    # 控制游戏帧率
    clock.tick(FPS)

# 结束游戏
pygame.quit()

在运行该代码之前，你需要先准备好一些游戏所需的图像资源，例如背景图、玩家图、子弹图、敌人图和爆炸效果图等。你可以从互联网上下载这些图像资源，然后将它们保存在与代码文件相同的目录下。
