基于光子统一回合的多人游戏

Question

我正在尝试创建一个简单的2D转弯为基础的多人游戏使用光子统一网络。

这只是一个简单的基于turn的游戏，其中player 1 (主机)按下他的按钮，它添加他的分数，并将其轮到player 2 (客户端)，后者按下他的按钮添加分数，并将turn改为player 1。它继续是无限的。

我能够使用基本的Photon文档连接游戏中的两个玩家。现在，我需要添加轮流和更改它们的网络逻辑。

我在网上找过了，但我不能理解光子的RPC和SerializeView。我真的对此感到困惑。请帮帮我。谢谢你以后再来。这是我的GameManager脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;

public class GameManager : Photon.PunBehaviour
{    
    public Text roomName;
    public Text player1Name,player2Name;
    public List<string> playersConnected = new List<string>();
    int scoreP1 = 0, scoreP2 = 0;
    public Text scoreTextP1, scoreTextP2;
    public Button p1Btn, p2Btn;
    int playerTurn = 1;

    void Start()
    {
        roomName.text = SceneManager.GetActiveScene().name;
        p2Btn.gameObject.SetActive(false);
        p1Btn.gameObject.SetActive(true);
    }    

    public void AddScoreP1()
    {
        scoreP1++;
        scoreTextP1.text = scoreP1.ToString();
        ChangePlayerTurn();
    }


    public void AddScoreP2()
    {
        scoreP2++;
        scoreTextP2.text = scoreP2.ToString();
        ChangePlayerTurn();
    }

    void ChangePlayerTurn()
    {
        if (playerTurn == 1)
        {
            playerTurn = 2;
            p2Btn.gameObject.SetActive(true);
            p1Btn.gameObject.SetActive(false);
        }
        else
        {
            playerTurn = 1;
            p1Btn.gameObject.SetActive(true);
            p2Btn.gameObject.SetActive(false);
        }
        print("Player Turn: P" + playerTurn);
    }

    void LoadArena()
    {
        if (!PhotonNetwork.isMasterClient)
        {
            Debug.LogError("PhotonNetwork : Trying to Load a level but we are not the master Client");
        }
        Debug.Log("PhotonNetwork : Loading Level : " + PhotonNetwork.room.PlayerCount);
        PhotonNetwork.LoadLevel("Room for " + PhotonNetwork.room.PlayerCount);
    }

    public override void OnLeftRoom()
    {
        SceneManager.LoadScene(0);
    }      

    public void LeaveRoom()
    {
        PhotonNetwork.LeaveRoom();
    }

    public override void OnPhotonPlayerConnected(PhotonPlayer other)
    {
        Debug.Log("OnPhotonPlayerConnected() " + other.NickName); // not seen if you're the player connecting
        foreach (PhotonPlayer _player in PhotonNetwork.playerList)
        {
            playersConnected.Add(other.NickName);
        }

        if (PhotonNetwork.isMasterClient)
        {
            Debug.Log("OnPhotonPlayerConnected isMasterClient " + PhotonNetwork.isMasterClient); // called before OnPhotonPlayerDisconnected

            LoadArena();
        }
    }

    public override void OnPhotonPlayerDisconnected(PhotonPlayer other)
    {
        Debug.Log("OnPhotonPlayerDisconnected() " + other.NickName); // seen when other disconnects
        foreach (PhotonPlayer _player in PhotonNetwork.playerList)
        {
            playersConnected.Remove(other.NickName);
        }

        if (PhotonNetwork.isMasterClient)
        {
            Debug.Log("OnPhotonPlayerDisonnected isMasterClient " + PhotonNetwork.isMasterClient); // called before OnPhotonPlayerDisconnected
            LoadArena();
        }
    }
}

RPC基本上是在远程客户端上调用函数的一种方式。

通常在多人游戏中，你会希望你的MasterClient来控制游戏的流程。所以，当两个玩家加入一个房间时，你需要做的就是从你的MasterClient中决定哪个玩家先走，然后从MasterClient调用一个RPC函数，告诉两个客户端第一个轮到谁。然后，无论轮到哪个玩家，只需激活它的按钮并让他们添加分数(也将RPC发送到MasterClient，以便每个人都能保持同步)。然后更新会通过另一个RPC告诉每个人，等等。

虽然您也可以在这种情况下使用事件，但使用它们需要的准备工作较少。
