Unity中MVC的简单应用

本篇简单介绍一下，Unity中MVC框架的简单应用。MVC自1982年被设计出来，至今都有着很大比重的使用率，特别是目前软件及游戏迭代此之快的情况下。高效的增删功能低耦合又小巧灵活的框架MVC，深受广大ProgramDesigner的喜爱。

数据是程序的灵魂，视图是看清灵魂的眼睛，控制器从中拨开迷雾，这就形成了现在的MVC。

简单实例：Model

using UnityEngine;

using System.Collections;

/// <summary>

/// 模型委托（当用户信息发生变化时执行）

/// </summary>

public delegate void OnValueChange (int val);

public class PlayerMsgModel

{

    //玩家等级

    private int playerLevel;

    //玩家经验

    private int playerExperience;

    //玩家升级经验

    private int playerFullExperience;

    //金币数量

    private int goldNum;

    //声明委托对象，接收当等级发生变化时，触发的事件

    public OnValueChange OnLevelChange;

    //声明委托对象，接收当经验发生变化时，触发的事件

    public OnValueChange OnExperienceChange;

    //声明委托对象，接收当升级经验发生变化时，触发的事件

    public OnValueChange OnFullExperienceChange;

    //声明委托对象，接收当金币数量发生变化时，触发的事件

    public OnValueChange OnGoldNumChange;

    //单例

    private static PlayerMsgModel mod;

    public static PlayerMsgModel GetMod ()

    {

        if (mod == null) {

            mod = new PlayerMsgModel ();

        }

        return mod;

    }

    private PlayerMsgModel ()

    {

    }

    /// <summary>

    /// 玩家等级属性

    /// </summary>

    /// <value>The player level.</value>

    public int PlayerLevel {

        get {

            return playerLevel;

        }

        set {

            playerLevel = value;

            //如果委托对象不为空

            if (OnLevelChange != null) {

                //执行委托

                OnLevelChange (playerLevel);

            }

        }

    }

    /// <summary>

    /// 玩家经验属性

    /// </summary>

    /// <value>The player experience.</value>

    public int PlayerExperience {

        get {

            return playerExperience;

        }

        set {

            playerExperience = value;

            if (OnExperienceChange != null) {

                OnExperienceChange (playerExperience);

            }

        }

    }

    /// <summary>

    /// 玩家升级经验属性

    /// </summary>

    /// <value>The player full experience.</value>

    public int PlayerFullExperience {

        get {

            return playerFullExperience;

        }

        set {

            playerFullExperience = value;

            if (OnFullExperienceChange != null) {

                OnFullExperienceChange (playerFullExperience);

            }

        }

    }

    /// <summary>

    /// 金币数量属性

    /// </summary>

    /// <value>The gold number.</value>

    public int GoldNum {

        get {

            return goldNum;

        }

        set {

            goldNum = value;

            if (OnGoldNumChange != null) {

                OnGoldNumChange (goldNum);

            }

        }

    }

}

简单实例：View

using UnityEngine;

using System.Collections;

using UnityEngine.UI;

public class PlayerMsgView : MonoBehaviour

{

    //UI

    public Text playerLevel;

    public Text playerExperience;

    public Text goldNum;

    public Button experienceUpButton;

    void Start ()

    {

        //委托事件绑定

        PlayerMsgModel.GetMod ().OnLevelChange += SetLevel;

        //委托事件绑定

        PlayerMsgModel.GetMod ().OnExperienceChange += SetExperience;

        PlayerMsgModel.GetMod ().OnFullExperienceChange += SetFullExperience;

        PlayerMsgModel.GetMod ().OnGoldNumChange += SetGoldNum;

        //View绑定按钮控制功能

        experienceUpButton.onClick.AddListener (

            PlayerMsgController.controller.OnExperienceUpButtonClick);

    }

    //修改UILevel值

    public void SetLevel (int level)

    {

        playerLevel.text = level.ToString ();

    }

    //修改UI经验值

    public void SetExperience (int experience)

    {

        //将字符串以“/”拆开

        string[] str = playerExperience.text.Split (new char []{ '/' });

        //用新的经验值重组

        playerExperience.text = experience + "/" + str [1];

    }

    public void SetFullExperience (int fullExiperience)

    {

        string[] str = playerExperience.text.Split (new char []{ '/' });

        playerExperience.text = str [0] + "/" + fullExiperience;

    }

    public void SetGoldNum (int goldn)

    {

        goldNum.text = goldn.ToString ();

    }

}

简单实例：Controller

using UnityEngine;

using System.Collections;

public class PlayerMsgController : MonoBehaviour

{

    public static PlayerMsgController controller;

    private int levelUpValue = 20;

    void Awake ()

    {

        controller = this;

    }

    void Start ()

    {

        PlayerMsgModel.GetMod ().PlayerLevel = 1;

        PlayerMsgModel.GetMod ().PlayerExperience = 0;

        PlayerMsgModel.GetMod ().PlayerFullExperience = 100;

        PlayerMsgModel.GetMod ().GoldNum = 0;

    }

    /// <summary>

    /// 提升经验按钮点击事件

    /// </summary>

    public void OnExperienceUpButtonClick ()

    {

        PlayerMsgModel.GetMod ().PlayerExperience += levelUpValue;

        if (PlayerMsgModel.GetMod ().PlayerExperience

            >= PlayerMsgModel.GetMod ().PlayerFullExperience) {

            PlayerMsgModel.GetMod ().PlayerLevel += 1;

            PlayerMsgModel.GetMod ().PlayerFullExperience +=

                200 * PlayerMsgModel.GetMod ().PlayerLevel;

            levelUpValue += 20;

            if (PlayerMsgModel.GetMod ().PlayerLevel % 3 == 0) {

                PlayerMsgModel.GetMod ().GoldNum +=

                    100 * PlayerMsgModel.GetMod ().PlayerLevel;

            }

        }

    }

}
