Unity3d基于Socket通讯例子(转)

按语：按照下文，服务端利用网络测试工具，把下面客户端代码放到U3D中摄像机上，运行结果正确。

在一个网站上看到有关于Socket的通讯事例，就拿来学习学习，高手就莫喷！ 原文链接：http://bbs.9ria.com/thread-364859-1-1.html 首先， 直接两个服务器端代码丢到相机上，然后也把客户端代码挂到相机上，发布服务端,再把服务器两个代码勾掉再发布客户端，最后运行服务端，再运行客户端。 unity里面展示：file:///C:/Users/Administrator/AppData/Local/YNote/data/qq233344ACD512D13C553FF71505B4C730/8d394e1cb202445dafbc1da3c2f90daa/clipboard.png <ignore_js_op>
