帮我用python做一个150行代码的弹珠小游戏

好的，下面是一个简单的弹珠小游戏的代码示例，共计约150行代码：

import pygame
import random

# 初始化pygame
pygame.init()

# 设置窗口大小
WINDOW_WIDTH = 600
WINDOW_HEIGHT = 800
window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption("弹珠小游戏")

# 设置颜色变量
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
BLUE = (0, 0, 255)

# 设置字体
font = pygame.font.SysFont(None, 45)

# 设置游戏变量
score = 0
lives = 3
game_over = False

# 创建弹珠类
class Ball(pygame.sprite.Sprite):
    def __init__(self, color, width, height):
        super().__init__()
        self.image = pygame.Surface([width, height])
        self.image.fill(color)
        self.rect = self.image.get_rect()
        self.velocity = [random.randint(4,8), random.randint(-8,8)]

    def update(self):
        self.rect.x += self.velocity[0]
        self.rect.y += self.velocity[1]
        if self.rect.right >= WINDOW_WIDTH or self.rect.left <= 0:
            self.velocity[0] = -self.velocity[0]
        if self.rect.top <= 0:
            self.velocity[1] = -self.velocity[1]

# 创建板子类
class Paddle(pygame.sprite.Sprite):
    def __init__(self, color, width, height):
        super().__init__()
        self.image = pygame.Surface([width, height])
        self.image.fill(color)
        self.rect = self.image.get_rect()
        self.rect.x = WINDOW_WIDTH // 2
        self.rect.y = WINDOW_HEIGHT - height

    def update(self):
        pos = pygame.mouse.get_pos()
        self.rect.x = pos[0]
        if self.rect.left <= 0:
            self.rect.left = 0
        elif self.rect.right >= WINDOW_WIDTH:
            self.rect.right = WINDOW_WIDTH

# 创建砖块类
class Brick(pygame.sprite.Sprite):
    def __init__(self, color, width, height):
        super().__init__()
        self.image = pygame.Surface([width, height])
        self.image.fill(color)
        self.rect = self.image.get_rect()

# 创建弹珠、板子、砖块组
all_sprites = pygame.sprite.Group()
balls = pygame.sprite.Group()
paddles = pygame.sprite.Group()
bricks = pygame.sprite.Group()

for i in range(3):
    ball = Ball(RED, 10, 10)
    ball.rect.x = random.randint(0, WINDOW_WIDTH)
    ball.rect.y = random.randint(0, WINDOW_HEIGHT // 2)
    balls.add(ball)
    all_sprites.add(ball)

paddle = Paddle(BLUE, 100, 10)
paddles.add(paddle)
all_sprites.add(paddle)

for i in range(10):
    brick = Brick(BLUE, 60, 15)
    brick.rect.x = i * 60 + 20
    brick.rect.y = 60
    bricks.add(brick)
    all_sprites.add(brick)

# 创建游戏循环
clock = pygame.time.Clock()

while not game_over:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True

    # 更新所有精灵
    all_sprites.update()

    # 检测弹珠与板子的碰撞
    if pygame.sprite.spritecollide(paddle, balls, False):
        for ball in balls:
            ball.velocity[1] = -ball.velocity[1]

    # 检测弹珠与砖块的碰撞
    for ball in balls:
        bricks_hit = pygame.sprite.spritecollide(ball, bricks, True)
        if bricks_hit:
            ball.velocity[1] = -ball.velocity[1]
            score += len(bricks_hit)

    # 检测弹珠是否落地
    for ball in balls:
        if ball.rect.bottom > WINDOW_HEIGHT:
            lives -= 1
            balls.remove(ball)
            all_sprites.remove(ball)
            if lives == 0:
                game_over = True
            else:
                ball = Ball(RED, 10, 10)
                ball.rect.x = random.randint(0, WINDOW_WIDTH)
                ball.rect.y = random.randint(0, WINDOW_HEIGHT // 2)
                balls.add(ball)
                all_sprites.add(ball)

    # 绘制所有精灵
    window.fill(WHITE)
    all_sprites.draw(window)

    # 绘制得分和生命值
    score_text = font.render("Score: {}".format(score), True, BLACK)
    window.blit(score_text, [10, 10])
    lives_text = font.render("Lives: {}".format(lives), True, BLACK)
    window.blit(lives_text, [WINDOW_WIDTH - 120, 10])

    # 更新屏幕
    pygame.display.update()

    # 设置帧率
    clock.tick(60)

# 游戏结束，显示最终得分
final_score_text = font.render("Final Score: {}".format(score), True, BLACK)
window.blit(final_score_text, [WINDOW_WIDTH // 2 - 100, WINDOW_HEIGHT // 2])
pygame.display.update()

# 停留3秒后退出游戏
pygame.time.wait(3000)
pygame.quit()

这个小游戏中，你需要控制板子移动，让弹珠不断反弹并消除所有砖块，同时要注意不让弹珠掉落到底部。游戏中包含了弹珠、板子、砖块三种元素，它们都是继承自pygame.sprite.Sprite类的精灵对象。游戏中使用了pygame.sprite.Group类来管理所有精灵对象，方便统一更新和绘制。

游戏的主要逻辑在游戏循环中，每次循环都要更新所有精灵的位置，检测碰撞和得分，并绘制得分和生命值。在游戏结束后，程序会停留3秒钟并退出游戏。
