python打乒乓球

以下是一个简单的Python打乒乓球游戏的示例代码：

import pygame
from pygame.locals import *

# 初始化游戏
pygame.init()

# 设置窗口大小
screen_width = 640
screen_height = 480
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("乒乓球游戏")

# 设置颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)

# 创建球拍类
class Paddle(pygame.sprite.Sprite):
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.Surface((100, 10))
        self.image.fill(WHITE)
        self.rect = self.image.get_rect()
        self.rect.centerx = screen_width // 2
        self.rect.bottom = screen_height - 20

    def update(self):
        # 控制球拍的移动
        pos = pygame.mouse.get_pos()
        self.rect.centerx = pos[0]
        self.rect.clamp_ip(screen.get_rect())

# 创建球类
class Ball(pygame.sprite.Sprite):
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.Surface((10, 10))
        self.image.fill(WHITE)
        self.rect = self.image.get_rect()
        self.rect.centerx = screen_width // 2
        self.rect.centery = screen_height // 2
        self.speed = [3, 3]

    def update(self):
        # 控制球的移动和碰撞检测
        self.rect.x += self.speed[0]
        self.rect.y += self.speed[1]

        if self.rect.left <= 0 or self.rect.right >= screen_width:
            self.speed[0] = -self.speed[0]
        if self.rect.top <= 0:
            self.speed[1] = -self.speed[1]
        if self.rect.colliderect(paddle.rect):
            self.speed[1] = -self.speed[1]

# 创建球拍和球的精灵组
all_sprites = pygame.sprite.Group()
paddle = Paddle()
ball = Ball()
all_sprites.add(paddle, ball)

# 游戏主循环
running = True
clock = pygame.time.Clock()
while running:
    clock.tick(60)

    # 处理事件
    for event in pygame.event.get():
        if event.type == QUIT:
            running = False

    # 更新精灵组
    all_sprites.update()

    # 绘制背景
    screen.fill(BLACK)

    # 绘制精灵组
    all_sprites.draw(screen)

    # 刷新屏幕
    pygame.display.flip()

# 退出游戏
pygame.quit()
