Unity3d游戏开发框架-标志量，数学管理类，时间管理，Log日志管理
本篇文章我们常州手机游戏开发培训-幻天网络给大家分享在游戏开发框架中常用到几个部分，包含标志量，数学管理类，时间管理，Log日志管理等，熟悉这几个相信对于大家的项目开发会很有帮助。
新建一个文件夹：Util
新建C#文件：
1.GmagFalag.cs
2.Log.cs
3.MathUtilLite.cs
4.TimeMgr.cs
标志量有什么用？可以标记人物的状态，攻击，奔跑·······
using UnityEngine;
using System.Collections;
public class GmagFalag
｛
/// <summary>

/// <summary>

｛

｝
set
｛

｝
｝
public GmagFalag()
｛

public GmagFalag(long flag)
｛
mValue = flag;
｝
/// <summary>

public long AddFlag(long flag)

/// <summary>
