一、注册创建应用

 创建

导入Photon和游戏素材发现有个这个提示，官网的意思是用到了试验性质的库存在风险

配置服务器信息，需要配置下Region，不配置随机分配，你和小伙伴可能不在一个服务器哦，我的配置如下

官方的Region

Region	Hosted in	Token
Asia	Singapore	asia
Australia	Melbourne	au
Canada, East	Montreal	cae
Chinese Mainland1 (See Instructions)	Shanghai	cn
Europe	Amsterdam	eu
India	Chennai	in
Japan	Tokyo	jp
Russia	Moscow	ru
Russia, East	Khabarovsk	rue
South Africa	Johannesburg	za
South America	Sao Paulo	sa
South Korea	Seoul	kr
Turkey	Istanbul	tr
USA, East	Washington D.C.	us
USA, West	San José	usw

新建一个NetworkLauncher，然后创建一个脚本

 给玩家增加Photon View

修改PlayerControler代码

 将Player添加到网络资源中

运行游戏如果出现下面错误

NullReferenceException: Object reference not set to an instance of an object PlayerControler.Movement () (at Assets/Script/PlayerControler.cs:39) PlayerControler.Update () (at Assets/Script/PlayerControler.cs:33)

说明摇杆的游戏对象是空的

通过下面代码解决

private VariableJoystick _variableJoystick;
private GameObject _variableJoystickGameObject;
void Start()
{
_variableJoystickGameObjec
t = GameObject.Find("Variable Joystick");
        VariableJoystick variableJoystick = _variableJoystickGameObject.GetComponent<VariableJoystick>();
        _variableJoystick = variableJoystick;
}

 好了可以预览游戏啦

 NetworkLauncher中的代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;

public class NetworkLauncher : MonoBehaviourPunCallbacks
{
    // Start is called before the first frame update
    void Start()
    {
        PhotonNetwork.ConnectUsingSettings();
    }

    public override void OnConnectedToMaster()
    {
        base.OnConnectedToMaster();
        Debug.LogWarning("Welcome Master!");
        PhotonNetwork.JoinOrCreateRoom("Room", new Photon.Realtime.RoomOptions() { MaxPlayers = 20 }, default);
    }

    public override void OnJoinedRoom()
    {
        base.OnJoinedRoom();
        PhotonNetwork.Instantiate("Player", new Vector2(1, 1), Quaternion.identity, 0);
    }
}
