Question

我为我的游戏编写了日夜系统，但我遇到了其中一种方法的问题。到目前为止，除了一种方法之外我编码得很好。这是完整的代码：

using Plus.Utilities;
using System;
using System.Collections.Generic;
using System.Linq;

namespace Plus.Roleplay.GameEnvironment
{
    class GameEnvironmentHandler
    {
        private List<TimeSpan> _darkTimes;
        private List<TimeSpan> _lightTimes;

        public GameEnvironmentHandler()
        {
            _darkTimes = new List<TimeSpan>
            {
                new TimeSpan(19, 0, 0),
                new TimeSpan(19, 30, 0),
                new TimeSpan(20, 0, 0),
                new TimeSpan(20, 30, 0),
                new TimeSpan (21, 0, 0)
            };

            _lightTimes = new List<TimeSpan>
            {
                new TimeSpan(06, 0, 0),
                new TimeSpan(06, 30, 0),
                new TimeSpan(07, 0, 0),
                new TimeSpan(07, 30, 0),
                new TimeSpan (08, 0, 0)
            };
        }

        public bool IsGettingDark()
        {
            return RoleplayHelper.IsTimeOfDayBetween(DateTime.Now,
                _darkTimes.First(), _darkTimes.Last());
        }

        public bool IsGettingLight()
        {
            return RoleplayHelper.IsTimeOfDayBetween(DateTime.Now,
                _lightTimes.First(), _lightTimes.Last())
                || RoleplayHelper.IsTimeOfDayBetween(DateTime.Now, 
                _lightTimes.First(), _darkTimes.Last());
        }
    }
}

我遇到问题的方法是IsGettingLight（），我编写了它来检查时间是否在第一次和最后一次光照时间之间，但是如果它在最后一次开始变亮之后，在第一次之前时间变暗，我怎样才能检查它是否变暗，变暗或变暗？我知道它与在第一个黑暗时间消除一点时间有关，但我究竟要删除什么，以及如何删除？

这是一种方法：

// firstLight starts at 5:30
var firstLight = new TimeSpan(5, 30, 0);

// fullLight start at 8:00
var fullLightStart = new TimeSpan(8, 0, 0);

// first Darkness starts at 18:30
var firstDark = new TimeSpan(18, 30, 0);

// fullDarkness starts at 21:00
var fullDarkStart = new TimeSpan(21, 0, 0);

然后，要查看当天您所处的位置，您可以将当前TimeOfDay与上述值进行比较：

var currentTime = DateTime.Now.TimeOfDay;

var IsGettingLight = currentTime >= firstLight && currentTime < fullLightStart;
var IsFullLight = currentTime >= fullLightStart && currentTime < firstDark;
var IsGettingDark = currentTime >= firstDark && currentTime < fullDarkStart;
var IsFullDark = currentTime >= fullDarkStart || currentTime < firstLight;

var IsLight = IsGettingLight || IsFullLight;
var IsDark = IsGettingDark || IsFullDark;

日夜系统，即使没有光线也检查灯光？
