帮我用Python写一个接球小游戏

好的，我可以回答这个问题。以下是一个简单的Python接球小游戏的代码：

import pygame
import random

# 初始化pygame
pygame.init()

# 设置窗口大小
screen_width = 500
screen_height = 500
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("接球小游戏")

# 设置颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)

# 设置球和板子的大小和速度
ball_size = 25
ball_speed = 5
paddle_width = 75
paddle_height = 15
paddle_speed = 5

# 创建球和板子
ball = pygame.Rect(screen_width/2 - ball_size/2, 0, ball_size, ball_size)
paddle = pygame.Rect(screen_width/2 - paddle_width/2, screen_height - paddle_height, paddle_width, paddle_height)

# 设置分数
score = 0
font = pygame.font.Font(None, 30)

# 游戏循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 移动板子
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT] and paddle.left > 0:
        paddle.left -= paddle_speed
    if keys[pygame.K_RIGHT] and paddle.right < screen_width:
        paddle.right += paddle_speed

    # 移动球
    ball.top += ball_speed

    # 碰撞检测
    if ball.top < 0:
        ball_speed = -ball_speed
    if ball.colliderect(paddle):
        ball_speed = -ball_speed
        score += 1
    if ball.bottom > screen_height:
        running = False

    # 生成新球
    if ball.top > screen_height/3:
        if random.randint(0, 10) == 0:
            ball = pygame.Rect(random.randint(0, screen_width-ball_size), 0, ball_size, ball_size)
            ball_speed = 5

    # 绘制界面
    screen.fill(white)
    pygame.draw.rect(screen, black, paddle)
    pygame.draw.ellipse(screen, red, ball)
    score_text = font.render("Score: " + str(score), True, black)
    screen.blit(score_text, (10, 10))
    pygame.display.flip()

# 退出游戏
pygame.quit()

希望这个代码能够帮助你实现一个简单的接球小游戏。
