说一下Photo服务器

误打误撞学习了一下Photo服务器，自己去百度上找，有些问题大家也没说清楚，所以，在这里补充说明一下：

现在Photo官网已经更新到4.0.29（说不定有更新了），但是很多教程都是Photo3.0的版本，虽然大体还是差不多，但是对于初学者来说还是非常苦恼的

所以本人在这提供Photo3.0版本的下载链接：链接：http://pan.baidu.com/s/1pL16a2v 密码：hvwi

我使用Photo中提供的Lite实现了一个简单的聊天，因为Lite服务器中没有聊天的事件，所以我们要自己写并且注册聊天事件

首先我们仿照Lite服务器中的事件使用枚举声明聊天事件

然后，在OnGUI函数中注册这个事件：

 然后，在OnEvent()函数中就可以半段这个方法了：

完成这些，一个简单的聊天的程序就完成了，附上完整的脚本。
