       前面的已经介绍了vp_Timer(点击前往查看），vp_TimeUtility相对简单很多，vp_TimeUtility定义了个表示时间的结构Units：

/// <summary>
/// represents a time measured in standard units
/// </summary>
public struct Units
{

	public int hours;
	public int minutes;
	public int seconds;
	public int deciSeconds;		// a.k.a. 'tenths of a second'
	public int centiSeconds;	// a.k.a. 'hundredths of a second'
	public int milliSeconds;
}

       下面就直接贴出时间与Units的转换，Units转换为string,时间转换为时钟转过的度数的实现

 1.时间与Units的相互转换：

public static Units TimeToUnits(float timeInSeconds)
{
	Units iTime = new Units();
	iTime.hours = ((int)timeInSeconds) / 3600;
	iTime.minutes = (((int)timeInSeconds) - (iTime.hours * 3600)) / 60;
	iTime.seconds = ((int)timeInSeconds) % 60;

	iTime.deciSeconds = (int)((timeInSeconds - iTime.seconds) * 10) % 60;
	iTime.centiSeconds = (int)((timeInSeconds - iTime.seconds) * 100 % 600);
	iTime.milliSeconds = (int)((timeInSeconds - iTime.seconds) * 1000 % 6000);

	return iTime;
}
public static float UnitsToSeconds(Units units)
{

	float seconds = 0.0f;
	seconds += units.hours * 3600;
	seconds += units.minutes * 60;
	seconds += units.seconds;

	seconds += (float)units.deciSeconds * 0.1f;
	seconds += (float)(units.centiSeconds / 100);
	seconds += (float)(units.milliSeconds / 1000);

	return seconds;

}

 

2.时间转换为字符串string：

public static string TimeToString(float timeInSeconds, bool showHours, bool showMinutes, bool showSeconds,
									bool showTenths, bool showHundredths, bool showMilliSeconds,
									char delimiter = ':')
{

	Units iTime = TimeToUnits(timeInSeconds);

	string hours = (iTime.hours < 10) ? "0" + iTime.hours.ToString() : iTime.hours.ToString();
	string minutes = (iTime.minutes < 10) ? "0" + iTime.minutes.ToString() : iTime.minutes.ToString();
	string seconds = (iTime.seconds < 10) ? "0" + iTime.seconds.ToString() : iTime.seconds.ToString();
	string deciSeconds = iTime.deciSeconds.ToString();
	string centiSeconds = (iTime.centiSeconds < 10) ? "0" + iTime.centiSeconds.ToString() : iTime.centiSeconds.ToString();
	string milliSeconds = (iTime.milliSeconds < 100) ? "0" + iTime.milliSeconds.ToString() : iTime.milliSeconds.ToString();
	milliSeconds = (iTime.milliSeconds < 10) ? "0" + milliSeconds : milliSeconds;

	return ((showHours ? hours : "") +
		(showMinutes ? delimiter + minutes : "") +
		(showSeconds ? delimiter + seconds : "") +
		(showTenths ? delimiter + deciSeconds : "") +
		(showHundredths ? delimiter + centiSeconds : "") +
		(showMilliSeconds ? delimiter + milliSeconds : "")).TrimStart(delimiter);

}	

 

3.时间对应时钟的转过的度数：

private static float HoursToDegreesInternal(float hours, float minutes = 0.0f, float seconds = 0.0f)
{
	return (hours * 30.0f) + (minutes * 0.5f) + (seconds * 0.0083333333f);
}
private static float MinutesToDegreesInternal(float minutes, float seconds = 0.0f, float milliSeconds = 0.0f)
{
	return (minutes * 6.0f) + (seconds * 0.1f) + (milliSeconds * 0.0001f);
}

private static float SecondsToDegreesInternal(float seconds, float milliSeconds = 0.0f)
{
	return (seconds * 6.0f) + (milliSeconds * 0.006f);
}


private static float MilliSecondsToDegreesInternal(float milliSeconds)
{
	return milliSeconds * 0.36f;
}

 

小结：

       vp_TimeUtility确实简单，之前还以为计算角度会比较复杂，贴完代码发现我想多了。具体的代码可以下载Unity时钟定时器插件——Vision Timer源码分析之一的附件查看。

       刚好2:00，晚上还有做点erlang的事情，只能等明天在写了，明天打算介绍Unity3D Managed Coroutines with Start, Stop, Resume——TaskManager。
