MsgType.Connect

描述

用于传达已成功连接的内部网络系统消息。

请务必在客户端或服务器上使用 RegisterHandler。将 MsgType.Connect 作为参数插入以监听连接。

//Attach this script to your GameObject.
//Attach a NetworkManager component. To do this click Add Component, then go to Network>Network Manager.
//Create 2 Buttons (Create>UI>Button) and attach them to the fields in your GameObject’s Inspector by clicking and dragging the Buttons from your Hierarchy to the fields.

//This script allows you to start and stop a Server and Client by clicking buttons. It also detects when there has been a connection and calls a method when that happens.
