插件的詳解在鏈接里已經(jīng)說的很清楚了，這里主要說下我改了一些代碼讓timer支持時間戳。以及增加了暫停和繼續(xù)的方法。

先說說支持時間戳的部分：
外部接口加了個參數(shù)，用于判斷是否需要用時間戳：

// time + callback + [timer handle]
    public static void In(float delay, Callback callback, Handle timerHandle = null, bool isConvertDate = false)
    { Schedule(delay, callback, null, null, timerHandle, 1, -1.0f, isConvertDate); }

獲取剩余的時間，用于暫停和繼續(xù)

    /// <summary>
    /// 讀取本地存儲時間戳，獲取剩余的時間
    /// </summary>
    /// <param name="key"></param>
    /// <returns></returns>
    public static float ContinueStartForConvertDateTime(string key)
    {
        if (PlayerPrefs.GetString("key") == null)
            return -1;
        if (PlayerPrefs.GetString(key) != "" && Int64.Parse(PlayerPrefs.GetString(key)) != 0)
        {
            float time = (Int64.Parse(PlayerPrefs.GetString(key)) - CommonFuntion.ConvertDateTimeForMillise(DateTime.Now)) * 0.001f;
            UnityEngine.Debug.Log("----------------"+ time);
            if (time < 0)
                time = 0;
            return time;
        }
        else
            return -1;
    }

Schedule添加定時器方法中isConvertDate如果是true，定時器用的就是時間戳，同時存儲在本地數(shù)據(jù)中

        if(isConvertDate)
        {
            pauseTime = 0;
            long start = CommonFuntion.ConvertDateTimeForMillise(DateTime.Now);
            long end = CommonFuntion.ConvertDateTimeForMillise(DateTime.Now.AddMilliseconds(time * 1000));
            m_NewEvent.StartTimeDateTime = start;
            m_NewEvent.DueTimeDateTime= end;
            PlayerPrefs.SetString(dataKey, end.ToString());
            UnityEngine.Debug.Log(CommonFuntion.ConvertDateTime(DateTime.Now) + "---------------"+start + "------------"+ end + "----------"+(end- start)*0.001f+"-----"+time);
        }
        else
        {
            m_NewEvent.StartTime = Time.time;
            m_NewEvent.DueTime = Time.time + time;
        }
        m_NewEvent.Iterations = iterations;
        m_NewEvent.Interval = interval;

Update中增加判斷時間戳定時器完成條件：

            long start = CommonFuntion.ConvertDateTimeForMillise(DateTime.Now);
            // execute all due events
            if ((Time.time >= vp_Timer.m_Active[m_EventIterator].DueTime && vp_Timer.m_Active[m_EventIterator].DueTime != 0) || // time is up
                vp_Timer.m_Active[m_EventIterator].Id == 0 || (start >= vp_Timer.m_Active[m_EventIterator].DueTimeDateTime && vp_Timer.m_Active[m_EventIterator].DueTimeDateTime != 0))// event has been canceled ('Execute' will kill it)
                vp_Timer.m_Active[m_EventIterator].Execute();

DueTime數(shù)據(jù)處理的地方也要添加DueTimeDateTime相應(yīng)的處理：

        private void Recycle()
        {
            Id = 0;
            DueTime = 0.0f;
            //重置時間戳
            if(DueTimeDateTime > 0 && pauseTime <= 0)
                PlayerPrefs.SetString(dataKey, "");
            DueTimeDateTime = 0;

            StartTime = 0.0f;

            Function = null;
            ArgFunction = null;
            Arguments = null;

            if (vp_Timer.m_Active.Remove(this))
                m_Pool.Add(this);

#if (UNITY_EDITOR && DEBUG)
            EditorRefresh();
#endif

        }

        public void Execute()
        {

            // if either 'Id' or 'DueTime' is zero, this timer has been
            // canceled: recycle it!
            if (Id == 0 || (DueTime == 0.0f && DueTimeDateTime == 0))
            {
                Recycle();
                return;
            }

            // attempt to execute the callback function
            if (Function != null)
                Function();
            else if (ArgFunction != null)
                ArgFunction(Arguments);
            else
            {
                // function was null: nothing to do so abort
                Error("Aborted event because function is null.");
                Recycle();
                return;
            }

            // count down to recycling
            if (Iterations > 0)
            {
                Iterations--;
                // usually a timer has one default iteration and will
                // enter the below scope to get recycled right away ...
                if (Iterations < 1)
                {
                    Recycle();
                    return;
                }
            }

            // ... but if we end up here the timer either has atleast one
            // iteration left, or user set iterations to zero for infinite
            // repetition. either way: update due time with the interval
            DueTime = Time.time + Interval;
            DueTimeDateTime = CommonFuntion.ConvertDateTimeForMillise(DateTime.Now.AddMilliseconds(Interval * 1000));
        }

在SchedulingDemo場景中進行測試
SchedulingDemo腳本中我的測試代碼：

    void Start()
    {
        float time = vp_Timer.ContinueStartForConvertDateTime(vp_Timer.dataKey);
        PlayerPrefs.SetString(vp_Timer.dataKey, "");
        if (time >= 0)
        {
            StartCoroutine(Test(time));
        }
    }
    IEnumerator Test(float time)
    {
        yield return new WaitForEndOfFrame();
        callback = SmackCube;
        vp_Timer.In(time, callback, 5, 0.5f, null, true);
    }
...
...
        if (DoButton("----10秒后執(zhí)行----5 iterations of a method, with 0.5 sec intervals"))
        {
            callback = SmackCube;
            vp_Timer.In(10f, SmackCube, 5, 0.5f, null, true);
        }
...
...

運行后

關(guān)閉后重新運行，實現(xiàn)重新進游戲繼續(xù)計時。

可以看出時間戳數(shù)據(jù)我用的都是精確到毫秒的，因為在Update中有獲取數(shù)據(jù)，如果只是精確到秒的話，一下就被判定是完成了。

timer沒有封裝暫停和繼續(xù)的方法，但是事件的數(shù)據(jù)都有封裝在Event里，所以加個暫停和繼續(xù)自然是no problem。。。于是馬上動手給他加了一個暫停和繼續(xù)的方法，我的思路是暫停的時候把活躍的Event列表和剩余時間存起來，繼續(xù)的時候再用對應(yīng)的剩余時間去激活，單個事件可以通過MethodName來暫停和繼續(xù)：
vp_Timer中新增的暫停接口：

    public static void PauseAll(string methodName = "")
    {
        if (methodName != "")
        {
            Event e = m_Active.Find((eventItem) => eventItem.MethodName == methodName);
            if (e == null)
                return;
            e.Paused = true;
            eventPauseList.Add(e);
            //暫停后剩余時間
            float residueTime = e.isConvertDate ? ((e.DueTimeDateTime - CommonFuntion.ConvertDateTimeForMillise(DateTime.Now)) * 0.001f) : (e.DueTime - e.StartTime) - e.LifeTime;
            UnityEngine.Debug.Log(e.MethodName + "-------Pause-------residueTime : " + residueTime);
            pauseTimeList.Add(residueTime);
            DestroyAll(methodName);
        }
        else
        {
            PauseDataSave();
            DestroyAll();
        }
    }
    private static void PauseDataSave()
    {
        for (int t = 0; t < m_Active.Count; t++)
        {
            if (m_Active[t].Paused)
                continue;
            m_Active[t].Paused = true;
            eventPauseList.Add(m_Active[t]);
            //暫停后剩余時間
            float residueTime = m_Active[t].isConvertDate ? ((m_Active[t].DueTimeDateTime - CommonFuntion.ConvertDateTimeForMillise(DateTime.Now)) * 0.001f) : (m_Active[t].DueTime - m_Active[t].StartTime) - m_Active[t].LifeTime;
            UnityEngine.Debug.Log(eventPauseList[t].MethodName + "-------PauseAll-------residueTime : " + residueTime);
            pauseTimeList.Add(residueTime);
        }
    }
    public static void ContiuePlayAll()
    {
        for (int t = 0; t < eventPauseList.Count; t++)
        {
            eventPauseList[t].Paused = false;
            Schedule(pauseTimeList[t], eventPauseList[t].Function, eventPauseList[t].ArgFunction, eventPauseList[t].Arguments, null, eventPauseList[t].Iterations, eventPauseList[t].Interval, eventPauseList[t].isConvertDate);
            UnityEngine.Debug.Log(eventPauseList[t].MethodName + "-------ContiuePlayAll-------pauseTimeList[t] : " + pauseTimeList[t]);
        }
        eventPauseList.Clear();
        pauseTimeList.Clear();
    }

SchedulingDemo腳本中我的測試代碼：

        if (GUI.Button(new Rect(Screen.width * 0.85f, Screen.width * 0.2f + Screen.width * 0.05f, Screen.width * 0.04f * 3, Screen.width * 0.04f), "Pause"))
        {
            if (callback != null)
                vp_Timer.PauseAll(callback.Method.Name);
        }
        
        if (GUI.Button(new Rect(Screen.width * 0.85f, Screen.width * 0.25f + Screen.width * 0.05f, Screen.width * 0.04f * 3, Screen.width * 0.04f), "PauseAll"))
        {
            vp_Timer.PauseAll();
        }

        if (GUI.Button(new Rect(Screen.width * 0.85f, Screen.width * 0.3f + Screen.width * 0.05f, Screen.width * 0.04f * 3, Screen.width * 0.04f), "PlayAll"))
        {
            vp_Timer.ContiuePlayAll();
        }

測試結(jié)果：

對時間戳定時的因為我有存本地數(shù)據(jù)，所以暫停和繼續(xù)只有在運行中有生效。

如果要實現(xiàn)某一個事件在延時幾秒后調(diào)幾次，間隔多少時間這種比較復(fù)雜的流程只要1句簡短的代碼就能搞定，想想是不是還有點小激動呢。

        if (DoButton("----10秒后執(zhí)行----5 次調(diào)用, 間隔 0.5 秒"))
        {
            callback = SmackCube;
            vp_Timer.In(10f, SmackCube, 5, 0.5f, null, true);
        }

這個插件還有做用字符串來標記delegate

今天的內(nèi)容就到這啦，研究完是不是覺得VisionTimer還蠻給力的呢。
