前言：

photon PUN是一款用于實現聯網對戰的插件，通過簡單的設計，就可以實現加入大廳，加入房間，并且進行對戰，玩家可以同步動畫和位置等參數，同時可以通過RPC機制，廣播參數，實現房間內的玩家消息共享。

對戰實現

1.打開photon官網，再打開賬號，登錄。

2.點擊Your Applications，創建應用，選擇PUN,按要求填寫，然后再復制Appid,打開unity創建項目。

3.在unity的資源商店中搜索photon PUN，下載導入。

4.粘貼剛才復制的appid,點擊setup project—close

5.新建一個場景，添加如下的UI組件，一個是名字輸入面板，點擊之后進入大廳。

6.在場景中新建一個空物體，命名NetWorkManager，同樣新建一個腳本NetworkManager，填充命名空間PUN，更改繼承類為MonoBehaviourPunCallbacks，首先在start函數中啟動。連接服務器，具體的代碼如下：

using System.Collections; using System.Collections.Generic; using UnityEngine; using Photon.Pun; using UnityEngine.UI; using Photon.Realtime;public class NetworkManager : MonoBehaviourPunCallbacks {#region 私有變量#endregion#region 公開變量public static NetworkManager _instance;//單例public InputField nameInputField;//名字輸入框public InputField RoomnameInputField;//房間名輸入框public GameObject readyBtn;//準備按鈕public GameObject startBtn;//開始游戲按鈕public GameObject NamePanel;//名字設置面板public GameObject LobbyPanel;//大廳面板public GameObject RoomPanel;//房間面板public GameObject StartInitPanel;//開始初始化面板#endregion#region Mono函數private void Awake(){if (_instance == null){_instance = this;}}private void Start(){PhotonNetwork.ConnectUsingSettings();//初始化設置，連接服務器}private void Update(){if (PhotonNetwork.LocalPlayer.IsMasterClient)//判斷是否是房主，是就顯示開始游戲按鈕，不是就顯示準備按鈕{readyBtn.SetActive(false);startBtn.SetActive(true);}else{readyBtn.SetActive(true);startBtn.SetActive(false);}}#endregion#region 按鈕函數/// <summary>/// 名字設置按鈕/// </summary>public void SetNicknameButton(){if (nameInputField.text.Length < 2)return;PhotonNetwork.NickName = nameInputField.text;//將輸入的名字上傳至網絡if(PhotonNetwork.InLobby)//判斷是否在大廳內，在就顯示大廳，隱藏名字面板{LobbyPanel.SetActive(true);NamePanel.SetActive(false);Debug.Log("已經在大廳中");}}/// <summary>/// 創建或加入房間按鈕/// </summary>public void joinOrCreateRoomBtn(){if(RoomnameInputField.text.Length<=2){return;}LobbyPanel.SetActive(false);RoomOptions roomOptions = new RoomOptions { MaxPlayers = 4 };//房間最大人數4人PhotonNetwork.JoinOrCreateRoom(RoomnameInputField.text, roomOptions, default);RoomPanel.SetActive(true);}#endregion#region Photon函數public override void OnJoinedRoom(){if (PhotonNetwork.LocalPlayer.IsMasterClient)//判斷是否是房主，是就顯示開始游戲按鈕，不是就顯示準備按鈕{readyBtn.SetActive(false);startBtn.SetActive(true);}else{readyBtn.SetActive(true);startBtn.SetActive(false);}}/// <summary>/// 當成功連接該服務器/// </summary>public override void OnConnectedToMaster(){NamePanel.SetActive(true);//顯示名字面板StartInitPanel.SetActive(false);//隱藏開始初始化面板PhotonNetwork.JoinLobby();//加入大廳Debug.Log("加入大廳成功");}#endregion }

7.新建一個RoomManagerList的空物體，同理新建一個RoomMnaager腳本，主要用來管理房間列表的顯示：

using Photon.Pun; using Photon.Realtime; using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;public class RoomManager : MonoBehaviourPunCallbacks {public GameObject roomNamePrefab;//房間顯示的預制體public Transform gridLayout;//預制體的父物體/// <summary>/// 房間更新的函數，每次房間消失或者增加，就會進行調用，所以要對消失的時候進行特殊處理/// </summary>/// <param name="roomList">返回的房間參數</param>public override void OnRoomListUpdate(List<RoomInfo> roomList){Debug.Log("roomlist:" + roomList.Count);for (int i = 0; i < gridLayout.childCount; i++)//遍歷父物體下的子物體{if (gridLayout.GetChild(i).gameObject.GetComponentInChildren<Text>().text == roomList[i].Name)//有相同的物體{Destroy(gridLayout.GetChild(i).gameObject);//銷毀if (roomList[i].PlayerCount == 0)//如果房間玩家為0{roomList.Remove(roomList[i]);//移除該房間}}}foreach (var room in roomList)//遍歷生成房間的顯示{GameObject newRoom = Instantiate(roomNamePrefab, gridLayout.position, Quaternion.identity, gridLayout);//生成房間按鈕newRoom.GetComponent<RoomBtn>().roomName = room.Name;//設置房間名字newRoom.GetComponentInChildren<Text>().text = room.Name + "(" + room.PlayerCount + "/4)";//顯示參數}} }

8.為了點擊房間按鈕，可以進入該房間，所以給按鈕添加腳本事件，新建一個腳本RoomBtn,房間按鈕是一個預制體，需要事先進行設置，在scroll view里面的content下新建按鈕，然后記得給content添加Vertical layout group和content size fitter組件，同理在玩家面板，也需要設計玩家對應的預制體，方法類似，代碼如下：

using Photon.Pun; using Photon.Realtime; using System.Collections; using System.Collections.Generic; using UnityEngine;public class RoomBtn : MonoBehaviourPunCallbacks {public string roomName;void Start(){}/// <summary>/// 點擊按鈕，加入該房間/// </summary>public void JoinRoomBtn(){PhotonNetwork.JoinRoom(roomName);//加入房間NetworkManager._instance.RoomPanel.SetActive(true);//顯示房間面板NetworkManager._instance.LobbyPanel.SetActive(false);//隱藏大廳面板}}

9.在進入房間后，需要對玩家進行更新，同時要判斷是不是房主，如果是，房主則可以進行開始游戲，如果不是，則顯示一個準備按鈕。這里其實也可以做一個聊天的聯機，添加以下組件，作為聊天的輸入和顯示。

腳本InRoom代碼：

using Photon.Pun; using Photon.Realtime; using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;public class InRoom : MonoBehaviourPunCallbacks {public GameObject playerInfoPrefab;//玩家按鈕預制體public Transform conlayout;//父物體List<GameObject> mplayers = new List<GameObject>();Player[] allplayers;bool ready = false;public InputField contentInput;//聊天輸入框public GameObject textPrefab;//文本預制體public Transform layoutContent;//父物體void Start(){}/// <summary>/// 當加入房間時/// </summary>public override void OnJoinedRoom(){allplayers = PhotonNetwork.PlayerList;foreach (var item in allplayers){GameObject obj = Instantiate(playerInfoPrefab, conlayout);m_PlayerInfo _PlayerInfo = obj.GetComponent<m_PlayerInfo>();_PlayerInfo.playerName = item.NickName;obj.GetComponentInChildren<Text>().text = item.NickName + "(" + "未準備" + ")";mplayers.Add(obj);}}/// <summary>/// 當有玩家進入時，更新玩家列表/// </summary>/// <param name="newPlayer"></param>public override void OnPlayerEnteredRoom(Player newPlayer){GameObject obj = Instantiate(playerInfoPrefab, conlayout);m_PlayerInfo _PlayerInfo = obj.GetComponent<m_PlayerInfo>();_PlayerInfo.playerName = newPlayer.NickName;obj.GetComponentInChildren<Text>().text = newPlayer.NickName+"("+"未準備"+")";mplayers.Add(obj);}/// <summary>/// 當有玩家離開時，更新玩家列表/// </summary>/// <param name="otherPlayer"></param>public override void OnPlayerLeftRoom(Player otherPlayer){foreach (var item in mplayers){if (item.GetComponentInChildren<Text>().text.Contains(otherPlayer.NickName)){Destroy(item);break;}}}/// <summary>/// 當離開房間時，如果房間內還有人，則設置其他人為房主/// </summary>public override void OnLeftRoom(){foreach (var item in mplayers){if (item.GetComponentInChildren<Text>().text.Contains(PhotonNetwork.LocalPlayer.NickName)){if (PhotonNetwork.LocalPlayer.IsMasterClient){foreach (var p in allplayers){if (p != PhotonNetwork.LocalPlayer){PhotonNetwork.CurrentRoom.SetMasterClient(p);break;}}}Destroy(item);break;}}}Dictionary<string, bool> IsPlayerReady = new Dictionary<string, bool>();//使用字典來進行數據廣播，廣播字典/// <summary>/// 準備按鈕事件/// </summary>public void SetReadyBtn(){foreach (var item in mplayers){m_PlayerInfo playerinfo = item.GetComponent<m_PlayerInfo>();if (!IsPlayerReady.ContainsKey(playerinfo.playerName)){IsPlayerReady.Add(playerinfo.playerName, false);}}ready = !ready;foreach (var item in IsPlayerReady){if(item.Key== PhotonNetwork.LocalPlayer.NickName){IsPlayerReady[item.Key] = ready;break;}}photonView.RPC("ReadyBtn", RpcTarget.All,PhotonNetwork.LocalPlayer.NickName,IsPlayerReady);}[PunRPC]void ReadyBtn(string xname,Dictionary<string,bool> keyValuePairs){foreach (var item in keyValuePairs){if(item.Value==true){foreach (var p in mplayers){if(p.GetComponentInChildren<Text>().text.Contains(item.Key)){p.GetComponentInChildren<Text>().text = item.Key + "(" + "已準備" + ")";break;}}}else{foreach (var p in mplayers){if (p.GetComponentInChildren<Text>().text.Contains(item.Key)){p.GetComponentInChildren<Text>().text = item.Key + "(" + "未準備" + ")";break;}}}}//foreach (var item in mplayers)//{// Debug.Log(item.GetComponentInChildren<Text>().text);// if (item.GetComponentInChildren<Text>().text.Contains(xname))// {// if(ready)// {// item.GetComponentInChildren<Text>().text= xname + "(" + "已準備" + ")";// }// else// {// item.GetComponentInChildren<Text>().text = xname + "(" + "未準備" + ")";// }// break;// }//}}//發送消息public void SendMessInfoBtn(){string info = PhotonNetwork.LocalPlayer.NickName + " :" + contentInput.text;photonView.RPC("SendMess", RpcTarget.All,info);}[PunRPC]void SendMess(string mess){GameObject textobj = Instantiate(textPrefab, layoutContent);textobj.GetComponentInChildren<Text>().text = mess;}//開始游戲public void StartGameButton(){photonView.RPC("LoadGameScene", RpcTarget.All);}[PunRPC]void LoadGameScene(){PhotonNetwork.LoadLevel(1);} }

這里還添加了一個代碼，綁定給玩家的按鈕，

代碼內容：

using System.Collections; using System.Collections.Generic; using UnityEngine;public class m_PlayerInfo : MonoBehaviour {public string playerName;}

10.新建一個場景，記得添加在build setting里面。在這個場景中，搭一個簡單的地面，同時新建一個膠囊體，作為玩家的預制體Player。添加以下組件，將他拖到以下的文件夾中，刪除場景中的Player：


11.新建一個腳本，命名為GameManager，主要是用來生成玩家，記得在場景中添加，代碼如下：

using Photon.Pun; using Photon.Realtime; using System.Collections; using System.Collections.Generic; using UnityEngine;public class GameManager : MonoBehaviourPunCallbacks {public static GameManager _insatnce;// Start is called before the first frame updatevoid Awake(){_insatnce = this;int index = 0;Player[] players = PhotonNetwork.PlayerList;foreach (var item in players){if (item.NickName == PhotonNetwork.NickName){index = item.ActorNumber - 1;// PhotonNetwork.Instantiate("Player", m_spawns.mySpawns[index].spawnPos.position, Quaternion.identity);PhotonNetwork.Instantiate("Player", Vector3.zero, Quaternion.identity);Debug.Log("userid:" + item.ActorNumber);}}} }

12.新建mPlayer腳本，用來控制玩家移動

using Photon.Pun; using System.Collections; using System.Collections.Generic; using UnityEngine;public class mPlayer : MonoBehaviourPunCallbacks {void Update(){if (photonView.IsMine){MoveController();}}public void MoveController(){float h = Input.GetAxis("Horizontal");float v = Input.GetAxis("Vertical");transform.Translate(new Vector3(h, 0, v) * 10 * Time.deltaTime);} }

13.這樣，一個基礎的聯機機制的小demo就完成了。其實整體來說，photon這套聯機機制，入門很簡單，但是后期拓展和優化需要花點時間。

最后是項目源碼：源碼地址
