【Unet】Unet Network Messages

Messages 消息传递机制 
首先要注册 接收回调函数 
服务器端
 NetworkServer.RegisterHandler(chatMessage, ServerReceiveMessage);
客户端
 NetworkManager.singleton.client.RegisterHandler(chatMessage, ReceiveMessage);
定义相同的聊天通道 
  private const short chatMessage = 131;（随便定义数字 保证相互通信的chatMessage  一样）
发送消息 CS 公用一个 Send
 NetworkManager.singleton.client.Send(chatMessage, myMessage);
会直接先回调到 服务器的接收函数 然后通过服务器接收函数中的 
 NetworkServer.SendToAll(chatMessage, myMessage);
发送给所有客户端（当然也有指定发送某个客户端）
 NetworkServer.SendToClient(1, chatMessage, myMessage);
剩下具体方法可查API
还有就是传递的消息
系统内置的是有三种
EmptyMessage
StringMessage
IntegerMessage

当然官方也提供自己定义的类 只要继承与MessageBase即可

 当然通信的前提 你需要开启 服务器 连入客户端 可以使用代码也可以添加NetWorkManager组件 + HUD 配合 达到通信效果
