運行實例演示.png

前言：

1.關于PureMVC:

MVC框架在很多項目當中擁有廣泛的應用，很多時候做項目前人開坑開了一半就消失了，后人為了填補各種的坑就遭殃的不得了。嘛，程序猿大家都不喜歡像文案策劃一樣組織文字寫東西，也不喜歡看別人留下不清不楚的文檔，還不如看代碼來得實在。剛開始新人看代碼是看得頭暈，因為這樣那樣的東西不一定能完全猜得透。而老人家就算有經驗和閱歷，也沒有這么多的體力去看一個龐大而又復雜的糟糕項目。因為這種需求，Unity3D的程序猿就統一組織起來，想做一個完整規范的程序框架，而這時，PureMVC就誕生了。我個人喜歡PureMVC的原因也很簡單，因為它簡單粗暴，和Unity3D之間沒有依賴性，加上又開源，真的遇到Bug能拿到源代碼來調試也是很容易執行的。Unity3D應用商店還有一個同類產品叫uFrame Game Framework，它對Unity版本有著依賴，拖視圖雖然方便，但是一旦出bug真的改得夠嗆的，所以不推薦使用它。下文便是使用PureMVC和Unity3D的UGUI制作一個簡單的員工管理系統實例。

2.通過MVC模式在Unity項目當中應用的特別提醒：

(1)Unity3D是基于組件設計的，如果沒有好的規劃，組件之間會產生復雜的調用關系，導致組件之間復雜的依賴，從而破壞了整個系統結構，因此需要設計時確定組件的層次關系，確保依賴關系只存在于下層對上層。而這個是業務邏輯設計問題，PureMVC幫不了你。
(2)僅僅用上MVC，解決不了什么問題，或許解決了1%，剩下的99%就被挪到了MVC的C里，當你慶祝MVC竣工時，99%的問題在那里默默的微笑的看著你。(話說以前寫PHP的CI框架時候，一堆東西扔到XxxAction.Class.php里面，發現和擺的亂七八糟的架構沒區別，只是大家都習慣了這套框架的規矩，看代碼找某個東西稍微好找而已，本質上還是考驗基本功和對項目的熟悉程度的，23333)

3.PureMVC通過4種pattern實現隔離變化：

(1)facade非常適合將UI界面對游戲數據的依賴解耦，將UI操作數據的請求封裝在facade 接口里面，同時數據變化對UI的影響可以通過notification事件通知來實現，該模式應用得非常常見。
(2)command模式統一對對象的操作，將鍵盤輸入，網絡輸入輸出統一成command來操控游戲對象。
(3)proxy維護數據，提供某塊數據統一的初始化，訪問和修改接口。
(4)mediator沒怎么用過，我們的游戲中的UI界面每次變化一般都是整體更新的，不常用局部更新。
以上4中pattern請務必牢牢記住，請務必牢牢記住，請務必牢牢記住。重要的事情要說3便。

4.PureMVC的流程示意圖

(1)在puremvc中，model/view/controller統一是由Facade類的單件實例來統籌管理的。
(2)PureMVC的基本流程：啟動PureMVC—>建立Mediator來操作視覺元素（按鈕與文本框）—>點擊按鈕發送Notification->文本框接收Notification改變內容。
(3)大致流程可理解為：通過Facade類的單件實例（即：統一的門面） 啟動 puremvc環境，啟動同時注冊Command對象(相當于asp.net mvc中的controller)，然后Command通過與之關聯的facade(即前面的單件實例)來注冊Mediator(中介者：用于把View與Command聯系起來)。
(4)當UI界面(即View)上有動靜時（比如按鈕點擊了之類），與之關聯的Mediator(中介者)會發送通知給facade，然后facade會調用command對象執行相關的處理。(即：消息響應)

一.引入PureMVC的插件

1.下載PureMVC

請訪問地址
https://github.com/PureMVC/puremvc-csharp-standard-framework/wiki

安裝

2.把PureMVC.DotNET.35.dll放到Plugins里面就好了。

QA

3.這里有一個很簡單的基本案例可以參考一下
http://www.open-open.com/lib/view/open1452657515480.html

二.動手配置文件

1.需要完成的實例如下：

實現的界面效果.png

2.具體實現的目標：

(1)在Scripts文件夾下，分別設置模型、視圖、控制器對應的文件夾Model、View、Controller，分別放置處理數據模型的腳本、處理顯示視圖的腳本、處理邏輯控制的腳本。
(2)如界面，一個Unity3D和UGUI制作的簡單員工管理系統，Employee Admin，其中員工界面Users顯示有哪些員工在登記范圍內，而New和Delete分別是添加和刪除某個員工的信息。然后下面的員工信息界面User Profile則是對員工信息的一個具體編輯和修正。

三.主要實現步驟

1.啟動文件AppFacade.cs 作為PureMVC框架的入口文件。

using UnityEngine;
using System.Collections;
using PureMVC.Patterns;
using PureMVC.Interfaces;

//Facade模式的單例
public class ApplicationFacade : Facade
{
    //實例化函數，保證單例模式(Singleton)運行該函數
    public new static IFacade Instance
    {
        get
        {
            if(m_instance == null)
            {
                lock(m_staticSyncRoot)
                {
                    if (m_instance == null)
                    {
                        Debug.Log("ApplicationFacade");
                        m_instance = new ApplicationFacade();
                    }
                }
            }
            return m_instance;
        }
    }
    //啟動PureMVC的入口函數
    public void Startup(MainUI mainUI)
    {
        Debug.Log("Startup() to SendNotification.");
        SendNotification(EventsEnum.STARTUP, mainUI);
    }
    //該類的構造器
    protected ApplicationFacade()
    {

    }
    //設置靜態
    static ApplicationFacade()
    {

    }
    //初始化控制器函數
    protected override void InitializeController()
    {
        Debug.Log("InitializeController()");
        base.InitializeController();
        RegisterCommand(EventsEnum.STARTUP, typeof(StartupCommand));
        RegisterCommand(EventsEnum.DELETE_USER, typeof(DeleteUserCommand));
    }
}

2.對PureMVC需要處理的事件用EventsEnum.cs存放

using UnityEngine;
using System.Collections;

//處理事件的枚舉
public class EventsEnum
{
    public const string STARTUP = "startup";//啟動事件

    public const string NEW_USER = "newUser";//新建用戶
    public const string DELETE_USER = "deleteUser";//刪除用戶
    public const string CANCEL_SELECTED = "cancelSelected";//取消選擇

    public const string USER_SELECTED = "userSelected";//選擇用戶
    public const string USER_ADDED = "userAdded";//添加用戶
    public const string USER_UPDATED = "userUpdated";//更新用戶
    public const string USER_DELETED = "userDeleted";//刪除用戶

    public const string ADD_ROLE = "addRole";//添加角色
    public const string ADD_ROLE_RESULT = "addRoleResult";//查詢添加角色的結果
}

3.然后在Unity的場景中創建一個MainUI.cs文件，掛在需要啟動PureMVC的組件上。就可以啟動了。

using UnityEngine;
using System.Collections;

//處理該UI場景的入口
public class MainUI : MonoBehaviour
{
    public UserList userList;
    public UserForm userForm;
    //啟動函數
    void Awake()
    {
        //啟動PureMVC程序，執行StartUP()方法
        ApplicationFacade facade = ApplicationFacade.Instance as ApplicationFacade;
        facade.Startup(this);
    }
}

4.對Controller部分進行處理

然后我們對執行邏輯的處理事件進行補充。新建一個文件夾Controller，暫時先放置StartupCommand.cs和DeleteUserCommand.cs。處理上述所說的邏輯事件
首先，處理啟動事件

using UnityEngine;
using System.Collections;
using PureMVC.Patterns;
using PureMVC.Interfaces;

//啟動事件
public class StartupCommand : SimpleCommand, ICommand
{
    //復寫原有的Execute執行函數
    public override void Execute(INotification notification)
    {
        //注冊統一的數據接口UserProxy，給其他事件處理
        Debug.Log("StartupCommand.Execute()");
        Facade.RegisterProxy(new UserProxy());

        //注冊局部界面Mediator，給其他事件處理
        MainUI mainUI = notification.Body as MainUI;
        Facade.RegisterMediator(new UserListMediator(mainUI.userList));
        Facade.RegisterMediator(new UserFormMediator(mainUI.userForm));
    }
}

其次，處理刪除用戶事件

using PureMVC.Patterns;
using PureMVC.Interfaces;

//刪除用戶事件
public class DeleteUserCommand : SimpleCommand, ICommand
{
   //復寫原有的Execute執行函數
    public override void Execute(INotification notification)
    {
        //獲取要刪除的對象user
        UserVO user = (UserVO)notification.Body;
        //獲取處理數據操作的userProxy
        UserProxy userProxy = (UserProxy)Facade.RetrieveProxy(UserProxy.NAME);

        //操作數據，刪除user
        userProxy.DeleteItem(user);
        //刪除完畢，廣播USER_DELETED進行通知
        SendNotification(EventsEnum.USER_DELETED);
    }
}

5.對Model部分進行處理

然后是對Model模型數據的定義哈,首先要記錄的信息用UserVO來表示

using UnityEngine;
using System.Collections;
//顯示用的數據信息UserViewObject
public class UserVO
{
    //用戶名
    public string UserName
    {
        get { return m_userName; }
    }
    private string m_userName = "";
    //名字
    public string FirstName
    {
        get { return m_firstName; }
    }
    private string m_firstName = "";
    //姓氏
    public string LastName
    {
        get { return m_lastName; }
    }
    private string m_lastName = "";
    //郵箱
    public string Email
    {
        get { return m_email; }
    }
    private string m_email = "";
    //密碼
    public string Password
    {
        get { return m_password; }
    }
    private string m_password = "";
    //部門
    public string Department
    {
        get { return m_department; }
    }
    private string m_department = "";
    //是否合法
    public bool IsValid
    {
        get
        {
            return !string.IsNullOrEmpty(UserName) && !string.IsNullOrEmpty(Password);
        }
    }
    //合并名字
    public string GivenName
    {
        get { return LastName + ", " + FirstName; }
    }
    //構造器
    public UserVO()
    {
    }
    //構造函數
    public UserVO(string uname, string fname, string lname, string email, string password, string department)
    {
        if (uname != null) m_userName = uname;
        if (fname != null) m_firstName = fname;
        if (lname != null) m_lastName = lname;
        if (email != null) m_email = email;
        if (password != null) m_password = password;
        if (department != null) m_department = department;
    }
}

接著對操作數據的UserProxy進行補充

using UnityEngine;
using System.Collections.Generic;
using PureMVC.Patterns;
using PureMVC.Interfaces;

//數據操作
public class UserProxy : Proxy, IProxy
{
    public new const string NAME = "UserProxy";

    //返回數據操作類
    public IList<UserVO> Users
    {
        get { return (IList<UserVO>) base.Data; }
    }

    //構造函數，添加幾條數據進去先
    public UserProxy():base(NAME, new List<UserVO>())
    {
        Debug.Log("UserProxy()");
        //添加幾條測試用的數據        
        AddItem(new UserVO("lstooge", "Larry", "Stooge", "larry@stooges.com", "ijk456", "ACCT"));
        AddItem(new UserVO("cstooge", "Curly", "Stooge", "curly@stooges.com", "xyz987", "SALES"));
        AddItem(new UserVO("mstooge", "Moe", "Stooge", "moe@stooges.com", "abc123", "PLANT"));
        AddItem(new UserVO("lzh", "abc", "def", "lzh@stooges.com", "abc123", "IT"));
    }

    //添加數據的方法
    public void AddItem(UserVO user)
    {
        Users.Add(user);
    }

    //更新數據的方法
    public void UpdateItem(UserVO user)
    {
        for (int i = 0; i < Users.Count; i++)
        {
            if (Users[i].UserName.Equals(user.UserName))
            {
                Users[i] = user;
                break;
            }
        }
    }

    //刪除數據的方法
    public void DeleteItem(UserVO user)
    {
        for (int i = 0; i < Users.Count; i++)
        {
            if (Users[i].UserName.Equals(user.UserName))
            {
                Users.RemoveAt(i);
                break;
            }
        }
    }
}

6.接下來對VIew部分進行實現

顯示用戶界面列表的UserList和填寫用戶具體信息的UserForm
列表單條數據部分

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

//UserList列表當中單條數據信息
public class UserList_Item : MonoBehaviour
{
    //定義UI組件
    public Text txt_userName;//用戶名文本框
    public Text txt_firstName;//名字文本框
    public Text txt_lastName;//姓氏文本框
    public Text txt_email;//郵件文本框
    public Text txt_department;//部門文本框

    //定義User信息類
    public UserVO userData;

    //更新User類
    public void UpdateData(UserVO data)
    {
        //獲取需要更改的User信息
        this.userData = data;

        //更改UI的文字信息
        txt_userName.text = data.UserName;
        txt_firstName.text = data.FirstName;
        txt_lastName.text = data.LastName;
        txt_email.text = data.Email;
        txt_department.text = data.Department;
    }
}

用戶列表部分

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

//UserList用戶界面列表部分
public class UserList : MonoBehaviour
{
    //定義UI組件
    public Text txt_userCount;//用戶列表文本框
    public UGUI_MyToggleGroup myToggleGroup;//用戶列表滑動條
    public Button btn_New;//新建按鈕
    public Button btn_Delete;//刪除按鈕
    public UserList_Item itemPrefab;//單個列表文件的預置體
    List<UserList_Item> itemList = new List<UserList_Item>();//臨時存列表

    //定義事件操作
    public System.Action NewUser;//添加用戶事件
    public System.Action DeleteUser;//刪除用戶事件
    public System.Action SelectUser;//選擇用戶事件

    //定義數據
    public UserVO SelectedUserData;//列表中選擇好的用戶
    private IList<UserVO> m_currentUsers;//當前選擇的用戶

    //開始函數
    void Start ()
    {
        itemPrefab.gameObject.SetActive(false);

        myToggleGroup.onToggleChange.AddListener(onSelectUserItem);
        btn_New.onClick.AddListener(onClick_btn_New);
        btn_Delete.onClick.AddListener(onClick_btn_Delete);

        UpdateButtons();
    }
    //加載用戶
    public void LoadUsers(IList<UserVO> list)
    {
        m_currentUsers = list;
        RefreshUI(list);
    }
    //點擊新建
    void onClick_btn_New()
    {
        if (NewUser != null) NewUser();
    }
    //點擊刪除
    void onClick_btn_Delete()
    {
        if (DeleteUser != null) DeleteUser();
    }
    //選擇物體
    void onSelectUserItem(Toggle itemToggle)
    {
        if (itemToggle == null)
        {
            return;
        }

        UserList_Item item = itemToggle.GetComponent<UserList_Item>();
        this.SelectedUserData = item.userData;
        UpdateButtons();
        if (SelectUser != null) SelectUser();

    }
    //取消選擇
    public void Deselect()
    {
        myToggleGroup.toggleGroup.SetAllTogglesOff();
        this.SelectedUserData = null;
        UpdateButtons();
    }
    //刷新UI
    void RefreshUI(IList<UserVO> datas)
    {
        ClearItems();
        foreach (var data in datas)
        {
            UserList_Item item = CreateItem();
            item.UpdateData(data);
            itemList.Add(item);
        }
        txt_userCount.text = datas.Count.ToString();
    }
    //新建列表項目
    UserList_Item CreateItem()
    {
        UserList_Item item = GameObject.Instantiate<UserList_Item>(itemPrefab);
        item.transform.SetParent(itemPrefab.transform.parent);
        item.gameObject.SetActive(true);
        item.transform.localScale = Vector3.one;
        item.transform.localPosition = Vector3.zero;

        return item;
    }
    //清空列表
    void ClearItems()
    {
        foreach(var item in itemList)
        {
            Destroy(item.gameObject);
        }
        itemList.Clear();
    }
    //更新按鈕
    private void UpdateButtons()
    {
        btn_Delete.interactable = (SelectedUserData != null);
    }
}

用戶個人信息部分

using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using UnityEngine.EventSystems;

//用戶個人信息表單模式?編輯:新增
public enum UserFormMode
{
    ADD,
    EDIT,
}
//用戶個人信息表單
public class UserForm : MonoBehaviour
{
    //UI項的定義
    public InputField txt_firstName;
    public InputField txt_lastName;
    public InputField txt_email;
    public InputField txt_userName;
    public InputField txt_password;
    public InputField txt_confirmPassword;
    public InputField txt_department;
    public Button btn_updateUser;
    public Button btn_cancel;

    //其他
    public System.Action AddUser;
    public System.Action UpdateUser;
    public System.Action CancelUser;

    //用戶信息獲取
    public UserVO User
    {
        get { return m_user; }
    }
    private UserVO m_user;

    //用戶信息表單
    public UserFormMode Mode
    {
        get { return m_mode; }
    }
    private UserFormMode m_mode = UserFormMode.ADD;

    //開始
    void Start ()
    {
        //設置UI
        btn_updateUser.onClick.AddListener(btn_updateUser_Click);
        btn_cancel.onClick.AddListener(btn_cancel_Click);

        txt_userName.onValueChange.AddListener(InputField_onValueChange);
        txt_password.onValueChange.AddListener(InputField_onValueChange);
        txt_confirmPassword.onValueChange.AddListener(InputField_onValueChange);

        UpdateButtons();
    }

    //顯示當前用戶信息
    public void ShowUser(UserVO user, UserFormMode mode)
    {
        m_mode = mode;
        if (user == null)
        {
            ClearForm();
        }
        else
        {
            m_user = user;
            txt_firstName.text = user.FirstName;
            txt_lastName.text = user.LastName;
            txt_email.text = user.Email;
            txt_userName.text = user.UserName;
            txt_password.text = txt_confirmPassword.text = user != null ? user.Password : "";
            txt_department.text = user.Department;
            //txt_firstName.ActivateInputField();
            EventSystem.current.SetSelectedGameObject(txt_firstName.gameObject);
            //txt_firstName.MoveTextEnd(false);
            txt_firstName.caretPosition = txt_firstName.text.Length - 1;
            UpdateButtons();
        }
    }

    //更新按鈕
    private void UpdateButtons()
    {
        if (btn_updateUser != null)
        {
            btn_updateUser.interactable = (txt_firstName.text.Length > 0 && txt_password.text.Length > 0 && txt_password.text.Equals(txt_confirmPassword.text));
        }
    }

    //清空表單
    public void ClearForm()
    {
        m_user = null;
        txt_firstName.text = txt_lastName.text = txt_email.text = txt_userName.text = "";
        txt_password.text = txt_confirmPassword.text = "";
        txt_department.text = "";
        UpdateButtons();
    }

    //更新用戶信息
    void btn_updateUser_Click()
    {
        m_user = new UserVO(
            txt_userName.text, txt_firstName.text, 
            txt_lastName.text, txt_email.text, 
            txt_password.text, txt_department.text);

        if (m_user.IsValid)
        {
            if (m_mode == UserFormMode.ADD)
            {
                if (AddUser != null) AddUser();
            }
            else
            {
                if (UpdateUser != null) UpdateUser();
            }
        }
    }

    //取消信息
    void btn_cancel_Click()
    {
        if (CancelUser != null) CancelUser();
    }

    //輸入
    void InputField_onValueChange(string value)
    {
        UpdateButtons();
    }
}

最后，對局部更新UI的行為進行完善Mediator

using UnityEngine;
using System.Collections;
using PureMVC.Patterns;
using PureMVC.Interfaces;
using System.Collections.Generic;
//更新UserList部分
public class UserListMediator : Mediator, IMediator
{
    private UserProxy userProxy;

    public new const string NAME = "UserListMediator";

    private UserList View
    {
        get { return (UserList)ViewComponent; }
    }

    public UserListMediator(UserList userList)
            : base(NAME, userList)
    {
        Debug.Log("UserListMediator()");
        userList.NewUser += userList_NewUser;
        userList.DeleteUser += userList_DeleteUser;
        userList.SelectUser += userList_SelectUser;
    }

    public override void OnRegister()
    {
        Debug.Log("UserListMediator.OnRegister()");
        base.OnRegister();
        userProxy = Facade.RetrieveProxy(UserProxy.NAME) as UserProxy;
        View.LoadUsers(userProxy.Users);
    }

    void userList_NewUser()
    {
        UserVO user = new UserVO();
        SendNotification(EventsEnum.NEW_USER, user);
    }
