Finding the correct position of the sun in dayCycles
Here's some data that I gathered using a test .daycycle file and another script
.daycycle Fraction is the fraction found in the .daycycle file under FRACTION #
The Time Fraction is the fraction by taking %timeOfDay/%dayLength.



I also have the file in .xls and .ods (for you OpenOffice users like me).

Here is some code snippets to convert from each fraction type as well as the simplified functions and their ranges from the data

Code: [Select]

//Simplified equations: f(x) is Sim Time Fraction, x is DayCycle Fraction
//f(x) = (7/6)x where x <= 0.6
//f(x) = (1/3)x where x > 0.6 and x <= 0.9
//f(x) = 2x where x > 0.9
function simTimeFractionToDaycycleFraction(%dayCycleFraction)
{
%dayCycleFraction = mClampF(%dayCycleFraction, 0.0, 1.0);

%simTimeFraction = (7/6) * %dayCycleFraction;
if(%dayCycleFraction <= 0.6)
return %simTimeFraction;

%simTimeFraction += (1/3) * %dayCycleFraction - 0.6;
if(%dayCycleFraction < 0.9)
return %simTimeFraction;

%simTimeFraction += 2 * %dayCycleFraction - 0.9;
return %simTimeFraction;
}

//Simplified equations: f(x) is DayCycle Fraction, x is Sim Time Fraction
//f(x) = (6/7)x where x <= 0.7
//f(x) = 3x where x > 0.7 and x <= 0.8
//f(x) = (1/2)x where x > 0.8
function simTimeFractionToDaycycleFraction(%simTimeFraction)
{
%simTimeFraction = mClampF(%simTimeFraction, 0.0, 1.0);

%dayCycleFraction = (6/7) * %simTimeFraction;
if(%simTimeFraction <= 0.7)
return %dayCycleFraction;

%dayCycleFraction += 3 * %simTimeFraction - 0.7;
if(%simTimeFraction <= 0.8)
return %dayCycleFraction;

%dayCycleFraction += (1/2) * %simTimeFraction - 0.8;
return %dayCycleFraction;
}
Now this is all cool, but the hell is it useful for?
Well, you could read a .daycycle file and grab specific values based on the time of day now, you can correctly determine whether it's day or night, and any other things you want :D

Other stuff
coming soon
