使用Pygame做一个乒乓球游戏。左侧为电脑右侧为玩家。 视频地址-YT 视频搬运-B站 视频教程约90分钟。 代码地址
环境需要pygame库可用pip安装pip install pygame
1. 基础版本 首先进行一些初始化初始化pygame以及物体的初始状态。 然后是主循环游戏的主循环主要包含3个内容
处理事件这里主要是键盘按键更新物体的状态在屏幕上绘制

为游戏添加分数显示添加字体并渲染出分数。发球时有3秒倒计时通过pygame.time.get_ticks() 获得时间。 # 添加得分和计时器

如果你运行了第2节的程序你会发现有时候球的反弹有时很奇怪比如有时候会黏在球拍上。 本节我们将
优化碰撞逻辑在ball_animation()通过判断球与球拍的位置修改球的运动。添加碰撞和得分音效: pygame.mixer.Sound
