MsgType.Connect

Description

Internal networking system message for communicating a connection has occurred.

Ensure you use RegisterHandler on the client or server. Insert MsgType.Connect as a parameter to listen for connections.

//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.
