ARCore开发报错The legacy networking system has been removed in Unity 2018.2. Use Unity Multiplayer。。。。。。

报错信息：The legacy networking system has been removed in Unity 2018.2. Use Unity Multiplayer and NetworkIdentity instead.'

报错原因：谷歌官方发布的ARCore版本与Unity更新后的方法弃用冲突。

解决办法：

1.引入

using UnityEngine;
using UnityEngine.Networking;

2.在start方法下

NetworkIdentity m_Identity;
    
    void Start()
    {
        //Fetch the NetworkIdentity component of the GameObject
        m_Identity = GetComponent<NetworkIdentity>();

        //Output to the console the connection associated with this NetworkIdentity
        Debug.Log("Connection : " + m_Identity.connectionToClient);
    }

 解决！
