Unity 关于MVC使用

背景

关于MVC，在某种程度的分离代码逻辑是必要的，可以提高代码的可维护性和重用性。
核心代码：
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;
    //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;
    }
    /// <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>
    /// 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);
            }
        }
    }
}

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().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)
    {
        playerExperience.text = experience.ToString();
    }
    //修改金币
    public void SetGoldNum(int goldn)
    {
        goldNum.text = goldn.ToString();
    }

}

Controller:

using UnityEngine;
using System.Collections;
public class PlayerMsgController 
{
    void Start()
    {
        PlayerMsgModel.GetMod().PlayerLevel = 1;
        PlayerMsgModel.GetMod().PlayerExperience =0;
        PlayerMsgModel.GetMod().GoldNum = 0;
    }

    /// <summary>
    /// 提升经验按钮点击事件
    /// </summary>
    public void OnExperienceUpButtonClick()
    {
        PlayerMsgModel.GetMod().PlayerExperience += levelUpValue;
        PlayerMsgModel.GetMod().PlayerLevel += 1;
        PlayerMsgModel.GetMod().GoldNum += 2;
        levelUpValue += 20;
    }
}
