System

System is a simple MonoBehavior that most likely will use URSA's magic methods in conjunction with SystemsExecutor. To get nice looking label you can inherit from SystemBase.

This is an example of a system:

publicclassTimeSystem:SystemBase{publicdoubledayDelta,prevDayTotal;publicdoubleprevTotaltime;intprevhour=-1;intcurrentHour;voidorderedFixedUpdate(){vartime=Pool<TimeData>.First.data;time.TotalTimePassed+=GetScaledDelta(time);time.DoubleTimeOfDay=time.TotalTimePassed%1;time.DoubleDelta=time.TotalTimePassed-prevTotaltime;time.TimeOfDay.Value=(float)(time.TotalTimePassed%1);if(currentHour!=prevhour){time.Hour.Value=currentHour;prevhour=time.Hour;}currentHour=(int)time.TimeOfDay.Remap(0f,1f,0f,24f);time.Delta=(float)time.DoubleDelta;if(time.TotalTimePassed-prevDayTotal>1.0){time.DoubleTimeOfDay=0.0+time.DoubleDelta;time.TimeOfDay.Value=(float)time.DoubleTimeOfDay;prevDayTotal=time.TotalTimePassed;}prevTotaltime=time.TotalTimePassed;}intGetCurrentHour(doubletod){return(int)(tod*24.0);}doubleGetDaylenght(TimeData.Datatime){return1440.0/time.DayLength;}doubleGetScaledDelta(TimeData.Datatime){doublescaled=Time.deltaTime*GetDaylenght(time);doublescaleBacktoHour=scaled.Remap(0,1440,0,1);doublegetMinute=scaleBacktoHour/60.0;doubleapplyMult=getMinute*time.SpeedMultiplier;returnapplyMult;}}

Despite most other systems being dependent on the work of this one, since all it does is modify the Time component, it is completely decoupled from the rest of the game. You can destroy it and no error will be thrown.
