生产一个大球吃小球的代码

以下是一个简单的 Python 代码实现：

import pygame, random

# 定义颜色常量
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)

# 初始化 Pygame
pygame.init()

# 设置窗口尺寸
SCREEN_WIDTH = 800
SCREEN_HEIGHT = 600
screen = pygame.display.set_mode([SCREEN_WIDTH, SCREEN_HEIGHT])

# 设置窗口标题
pygame.display.set_caption('大球吃小球')

# 创建大球类
class Ball(pygame.sprite.Sprite):
    def __init__(self, color, radius):
        super().__init__()
        self.color = color
        self.radius = radius
        self.image = pygame.Surface([radius * 2, radius * 2])
        self.image.fill(WHITE)
        pygame.draw.circle(self.image, color, [radius, radius], radius)
        self.rect = self.image.get_rect()

    def update(self):
        pass

# 创建小球类
class SmallBall(Ball):
    def __init__(self, color, radius, speed):
        super().__init__(color, radius)
        self.speed = speed
        self.rect.x = random.randrange(SCREEN_WIDTH - radius * 2)
        self.rect.y = random.randrange(SCREEN_HEIGHT - radius * 2)

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

# 创建大球对象
big_ball = Ball(RED, 50)
big_ball.rect.x = SCREEN_WIDTH / 2 - 50
big_ball.rect.y = SCREEN_HEIGHT / 2 - 50

# 创建小球列表
small_balls = pygame.sprite.Group()

# 创建多个小球对象
for i in range(25):
    color = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
    radius = random.randint(10, 20)
    speed = [random.randint(-5, 5), random.randint(-5, 5)]
    small_ball = SmallBall(color, radius, speed)
    small_balls.add(small_ball)

# 创建时钟对象
clock = pygame.time.Clock()

# 游戏主循环
done = False
while not done:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True

    # 获取鼠标位置
    pos = pygame.mouse.get_pos()

    # 移动大球
    big_ball.rect.x = pos[0]
    big_ball.rect.y = pos[1]

    # 检测大球是否吃掉小球
    small_balls_hit = pygame.sprite.spritecollide(big_ball, small_balls, True)
    for small_ball in small_balls_hit:
        # 创建新的小球
        color = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
        radius = random.randint(10, 20)
        speed = [random.randint(-5, 5), random.randint(-5, 5)]
        small_ball = SmallBall(color, radius, speed)
        small_balls.add(small_ball)

    # 更新小球位置
    small_balls.update()

    # 绘制屏幕
    screen.fill(BLACK)
    screen.blit(big_ball.image, big_ball.rect)
    small_balls.draw(screen)
    pygame.display.flip()

    # 控制帧率
    clock.tick(60)

# 退出 Pygame
pygame.quit()

运行以上代码，即可看到一个大球吃小球的小游戏界面。玩家可以通过鼠标控制大球移动，当大球碰到小球时，小球会被吃掉，并在其位置生成一个新的小球。
