Unity之计时器功能（转）

Unity时钟定时器插件——Vision Timer源码分析之二

       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;
}
