一个比较好的多人网络游戏菜单程序。

看完大神们的博客，作为一个初学者，同时第一次写博客，仅抄袭些简单的东西供大家参考。

关于U3D开发，我想说的是DO与WHY的问题。个人觉得程序开发，初学者需要的实际的操作，从实际案例中总结经验是去DO，而不是一味的追寻WHY，等到技术时机成熟了，自然知道了WHY。如果一直在原地问为什么？WHY？最后还是没有出发。所以不要管是不是有语言基础，只要想学，从简单的案例下手不断积累经验查漏补缺，我相信会越走越远。

/*一个比较好的多人网络游戏菜单程序
有兴趣尝试多人网络编程的话，大家可以试试下面的菜单代码，感觉还是不错的一段代码，功能比较全面，如果能应用到自己的工程中的话，相信会得到很不错的效果，不过在用之前最好能仔细的读一读，并且根据自己的工程进行稍微的调整，希望能对大家提供有用的帮助。*/
