如何在EditorWindow中暫停/繼續計時器？

Question

void OnGUI()
    {
        pauseCounting = GUILayout.Toggle(pauseCounting, "Pause timer");
        Timer();
    }

然后：

private void Timer()
    {
        if (stopCounting == false)
        {
            EditorGUILayout.LabelField("Count Each:", countTime + " Secs");

            if (waitForUI)
                timeToCount = nextCountTime - EditorApplication.timeSinceStartup;

            EditorGUILayout.LabelField("Next Count:", timeToCount.ToString() + " Sec");
            if (waitForUI == false)
            {
                timeToCount = 30;
                waitForUI = true;
            }

            this.Repaint();

            if (EditorApplication.timeSinceStartup > nextCountTime)
            {
                nextCountTime = EditorApplication.timeSinceStartup + countTime;
            }

        }
        else
        {
            EditorGUILayout.LabelField("Counting:", countTime + " Secs");
            EditorGUILayout.LabelField("Next Count:", countToSave.ToString() + " Sec");
        }
    }

問題是我現在使用的是EditorApplication.timeSinceStartup，如果我將stopCounting標志更改為true，然后又返回false，它將使用EditorApplication.timeSinceStartup進行計算，並且不會從停止點繼續。 我希望如果stopCounting為true，那么false再次從上次暫停開始繼續計時。

在您的班級中，添加一個字段以記錄總的滴答時間：

double timerRecord;

在您的onEnable中，將其初始化：

timerRecord = EditorApplication.timeSinceStartup;

在您的OnGUI（）中，添加一些邏輯以檢查“重新啟動”操作：

var shouldStop = GUILayout.Toggle(stopCounting, "Pause timer");
if(!shouldStop && stopCounting)
{
    // in this case, you restarted the timer.
    timerRecord = EditorApplication.timeSinceStartup;
}
stopCounting = shouldStop;
Timer();

最后，在您的Time（）中，將所有的'EditorApplication.timeSinceStartup'替換為'timerRecord'，最后，將其'timerRecord'的值替換為'EditorApplication.timeSinceStartup'。

timerRecord = EditorApplication.timeSinceStartup;
