Unity中使用MVC

首先我们先谈Unity3D本身的MonoBehavior脚本。

MonoBehavior我们可以将他理解为界面层与界面直接沟通的上层脚本，在他底部的控制，逻辑，数据等有必要用MonoBehavior脚本么？如果在unity中我们进行开发时如果滥用MonoBehavior脚本，无疑会造成相当高的耦合度，并且当我们对程序进行迭代时会变得困难重重。所以在这里介绍MVC框架来对代码进行解耦。

我们以创建一个玩家角色面板来演示

1.简单实例-Model

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

public class UserModel  {  
    private int currentExp;  
    private int fullExp;  
    private int cone;  
    private int level;  

    public UserModel()  
    {  
        level = 1;  
        cone = 0;  
        fullExp = 100;  
        currentExp = 0;  
    }  
    #region 字段封装  
    public int CurrentExp  
    {  
        get  
        {  
            return currentExp;  
        }  

        set  
        {  
            currentExp = value;  
        }  
    }  

    public int FullExp  
    {  
        get  
        {  
            return fullExp;  
        }  

        set  
        {  
            fullExp = value;  
        }  
    }  

    public int Cone  
    {  
        get  
        {  
            return cone;  
        }  

        set  
        {  
            cone = value;  
        }  
    }  

    public int Level  
    {  
        get  
        {  
            return level;  
        }  

        set  
        {  
            level = value;  
        }  
    }  
    #endregion  
}  

2.简单实例-View

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

public class UserView : MonoBehaviour {  
    private Text levelText;  
    private Text coneText;  
    private Text currentExp;  
    private Text fullExp;  
    [HideInInspector]  
    public Button addExp;  
    [HideInInspector]  
    public Button addCone;  

    private void Awake()  
    {  
        levelText = GameTool.FindTheChild(gameObject, "levelText").gameObject.GetComponent<Text>();  
        coneText = GameTool.FindTheChild(gameObject, "coneText").gameObject.GetComponent<Text>();  
        currentExp = GameTool.FindTheChild(gameObject, "currentExp").gameObject.GetComponent<Text>();  
        fullExp = GameTool.FindTheChild(gameObject, "fullExp").gameObject.GetComponent<Text>();  
        addExp = GameTool.FindTheChild(gameObject, "addExp").gameObject.GetComponent<Button>();  
        addCone = GameTool.FindTheChild(gameObject,"addCone").gameObject.GetComponent<Button>();  

    }  
    public void SetConeText(int cone)  
    {  
        coneText.text = cone.ToString();  
    }  
    public void SetFullExp(int fullexp)  
    {  
        this.fullExp.text = fullexp.ToString();  
    }  
    public void SetCurrentExp(int currentexp)  
    {  
        this.currentExp.text = currentexp.ToString();   
    }  
    public void SetLevelText(int level)  
    {  
        this.levelText.text = level.ToString();  
    }  
    private void Start()  
    {  

    }  
}  

3.简单实例-Controller

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

public class UserController : MonoBehaviour {  

    private UserView view;  
    private UserModel userModel;  
    private void Awake()  
    {  
        view = gameObject.GetComponent<UserView>();  
        userModel = new UserModel();  
    }  
    public void AddExp(GameObject go)  
    {  
        userModel.CurrentExp += 99;  
        if (userModel.CurrentExp>=userModel.FullExp)  
        {  
            userModel.CurrentExp = userModel.CurrentExp - userModel.FullExp;  
            LevelUP();  
        }  
        view.SetCurrentExp(userModel.CurrentExp);  
        view.SetFullExp(userModel.FullExp);  
        view.SetLevelText(userModel.Level);  
    }  
    public void AddCone(GameObject go)  
    {  
        userModel.Cone += 1000;  
        view.SetConeText(userModel.Cone);  
    }  
    public void LevelUP()  
    {  
        userModel.Level++;  
        userModel.FullExp = userModel.Level * 100;  
    }  
    // Use this for initialization  
    void Start () {  
        UGUIEventListener.Get(view.addCone.gameObject).onClick += AddCone;  
        UGUIEventListener.Get(view.addExp.gameObject).onClick += AddExp;  
    }  

    // Update is called once per frame  
    void Update () {  

    }  
}  

代码中使用到了两个简单的帮助类，很简单在其他博文中也介绍过，就不在介绍了。
