用法：直接繼承這個類去實現裡面的方法

using UnityEngine;
using System.Collections;


public static class testDataFlag
{
    public const int IntTemp = 1;
}


public class testData : Flag 


{
    private static testData instance;
    public static testData Instance
    {
        get
        {
            if (instance == null)
            {
                instance = new testData();
            }
            return instance;
        }
    }


    public void Method()
    {
        SetFlag(testDataFlag.IntTemp);
    }
}
 

呼叫：

using UnityEngine;
using System.Collections;


public class test : MonoBehaviour 
{


<span style="white-space:pre">	</span>// Use this for initialization
<span style="white-space:pre">	</span>void Start () 
    {
        testData.Instance.Method();
<span style="white-space:pre">	</span>}
<span style="white-space:pre">	</span>
<span style="white-space:pre">	</span>// Update is called once per frame
<span style="white-space:pre">	</span>void Update () 
    {
        if (testData.Instance.CheckFlag(testDataFlag.IntTemp))
        {
            Debug.LogError("小唐");
            testData.Instance.ClearFlag(testDataFlag.IntTemp);
        }
<span style="white-space:pre">	</span>}
