用Python写一个飞机大战

好的，以下是一个简单的飞机大战游戏的 Python 代码示例：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 窗口大小和标题
WIDTH = 480
HEIGHT = 600
WINDOW = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("飞机大战")

# 颜色定义
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)

# 加载背景音乐和音效
pygame.mixer.music.load("bgm.mp3")
pygame.mixer.music.play(-1)
bullet_sound = pygame.mixer.Sound("bullet.wav")
explosion_sound = pygame.mixer.Sound("explosion.wav")

# 加载图片
bg_image = pygame.image.load("background.png")
player_image = pygame.image.load("player.png")
enemy_image = pygame.image.load("enemy.png")
bullet_image = pygame.image.load("bullet.png")
explosion_images = []
for i in range(1, 6):
    explosion_images.append(pygame.image.load(f"explosion{i}.png"))

# 游戏对象类
class GameObject:
    def __init__(self, x, y, image):
        self.x = x
        self.y = y
        self.width = image.get_width()
        self.height = image.get_height()
        self.image = image

    def draw(self, surface):
        surface.blit(self.image, (self.x, self.y))

# 玩家类
class Player(GameObject):
    def __init__(self, x, y, image):
        super().__init__(x, y, image)
        self.speed = 5

    def move(self, dx, dy):
        self.x += dx * self.speed
        self.y += dy * self.speed
        # 限制玩家移动范围
        if self.x < 0:
            self.x = 0
        elif self.x > WIDTH - self.width:
            self.x = WIDTH - self.width
        if self.y < 0:
            self.y = 0
        elif self.y > HEIGHT - self.height:
            self.y = HEIGHT - self.height

    def shoot(self):
        bullet = Bullet(self.x + self.width // 2 - bullet_image.get_width() // 2, self.y, bullet_image)
        bullets.append(bullet)
        bullet_sound.play()

# 敌人类
class Enemy(GameObject):
    def __init__(self, x, y, image):
        super().__init__(x, y, image)
        self.speed = random.randint(1, 3)

    def move(self):
        self.y += self.speed

# 子弹类
class Bullet(GameObject):
    def __init__(self, x, y, image):
        super().__init__(x, y, image)
        self.speed = 10

    def move(self):
        self.y -= self.speed

# 爆炸类
class Explosion:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.images = explosion_images
        self.index = 0
        self.frame_rate = 5
        self.frame_count = 0

    def draw(self, surface):
        surface.blit(self.images[self.index], (self.x, self.y))
        self.frame_count += 1
        if self.frame_count % self.frame_rate == 0:
            self.index += 1
            if self.index >= len(self.images):
                explosions.remove(self)

# 创建游戏对象
player = Player(WIDTH // 2 - player_image.get_width() // 2, HEIGHT - player_image.get_height(), player_image)
enemies = []
bullets = []
explosions = []

# 游戏循环
running = True
clock = pygame.time.Clock()
while running:
    # 事件处理
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_ESCAPE:
                running = False
            elif event.key == pygame.K_SPACE:
                player.shoot()

    # 玩家移动
    keys = pygame.key.get_pressed()
    dx = keys[pygame.K_RIGHT] - keys[pygame.K_LEFT]
    dy = keys[pygame.K_DOWN] - keys[pygame.K_UP]
    player.move(dx, dy)

    # 敌人出现
    if random.randint(1, 100) == 1:
        enemy = Enemy(random.randint(0, WIDTH - enemy_image.get_width()), -enemy_image.get_height(), enemy_image)
        enemies.append(enemy)

    # 更新游戏对象状态
    for enemy in enemies:
        enemy.move()
        if enemy.y > HEIGHT:
            enemies.remove(enemy)
        elif enemy.y + enemy.height > player.y and enemy.x < player.x + player.width and enemy.x + enemy.width > player.x:
            explosions.append(Explosion(player.x, player.y))
            explosion_sound.play()
            running = False
    for bullet in bullets:
        bullet.move()
        if bullet.y < -bullet.height:
            bullets.remove(bullet)
        else:
            for enemy in enemies:
                if bullet.x < enemy.x + enemy.width and bullet.x + bullet.width > enemy.x and bullet.y < enemy.y + enemy.height and bullet.y + bullet.height > enemy.y:
                    enemies.remove(enemy)
                    bullets.remove(bullet)
                    explosions.append(Explosion(enemy.x, enemy.y))
                    explosion_sound.play()

    # 绘制游戏界面
    WINDOW.blit(bg_image, (0, 0))
    player.draw(WINDOW)
    for enemy in enemies:
        enemy.draw(WINDOW)
    for bullet in bullets:
        bullet.draw(WINDOW)
    for explosion in explosions:
        explosion.draw(WINDOW)
    pygame.display.update()

    # 游戏帧率控制
    clock.tick(60)

# 退出 Pygame
pygame.quit()

这是一个简单的版本，你可以根据需要进行修改和扩展。
