Unity中MVC的簡(jiǎn)單應(yīng)用

本篇簡(jiǎn)單介紹一下，Unity中MVC框架的簡(jiǎn)單應(yīng)用。MVC自1982年被設(shè)計(jì)出來(lái)，至今都有著很大比重的使用率，特別是目前軟件及游戲迭代此之快的情況下。高效的增刪功能低耦合又小巧靈活的框架MVC，深受廣大ProgramDesigner的喜愛(ài)。

數(shù)據(jù)是程序的靈魂，視圖是看清靈魂的眼睛，控制器從中撥開(kāi)迷霧，這就形成了現(xiàn)在的MVC。

簡(jiǎn)單實(shí)例：Model

using UnityEngine;

using System.Collections;

/// <summary>
