基于javafx，通过fxml实现交互的简单石头剪刀布游戏

一：前言

        在经历了一段时间的新学习（折磨加摸鱼）后，本人在上一篇博文的基础上制作了这一次的作品，说实话，fxml的使用就我目前感觉来，其实更加偏向实际操作，理论知识可能用到的较少（也有可能是我太菜了)，废话不多说，进入本次的主题吧！由于本人技术有限，期待各位读者在阅读后给出指正，谢谢！

二：总览

        

        主要还是有三个部分，登录注册，游戏画面，以及其他操作具体的简介已经放在代码注释中了，诸位读者请慢慢食用！

        另外，也先奉上fxml页面：

//由于本人写下这份博客匆忙，所以当前游戏时间暂时没有及时跟上

三：具体代码

        由于这个包内部类的功能其实和上一篇博客类似，所以这里不再过多赘述！

四：后话

        最近我在看红楼梦，我很喜欢那句“满纸荒唐言，谁解其中味”，正如我写的这些代码，其实在真正的高手眼中不过是一个刚学到新东西的毛头小子耍的三脚猫功夫，但我想，总会有读者能身有体会，在漫长的学习道路上，其中的酸甜苦辣，你知，我知。

       最后，感谢每一位读者！
