       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：

C#代码  收藏代码
/// <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：

C#代码  收藏代码
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：

C#代码  收藏代码
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：

C#代码  收藏代码
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。
