python开发五子棋8 #

UI右侧信息显示
人机大战的主函数整体实现

收获 #

了解五子棋人机交战背后的python原理，通过PyGame实践学会独立建立和更新项目，完成五子棋游戏开发

UI右侧信息显示 #

本小节为设定界面UI右侧信息显示的方法，包括目前交战双方执手，以及战况.

########################################在main主函数前，添加下列函数#################################################

人机大战的主函数整体实现 #

本小节为五子棋主函数的整体实现方法，可参考第四节中五子棋人人大战的主函数的实现方法，不同点在于使用AI类替换了原有对手的部分.

##################################将已有的五子棋人人大战的主函数替换为下列函数###################################
