Matthijs 40 Posted February 14, 2016 Inspired by MKY's blizzard script, I created functions that provide you with climatological information. The functions contain a simple climatological model and statistical data, that I gathered from all kinds or sources on the web. The climatological data can be overridden by terrain makers, using config entries. I hope that this will contribute to the creation of weather add-ons, realism- and survival mods. The archive includes a demonstration script. Download: https://drive.google.com/file/d/1mkwaLX9Mxri2tIQvB-25OJ99t-K_WPq6/view?usp=sharing FEATURES Input variables for functions are mostly limited to time, date and a position or object. Besides climatological data, the functions determine Latitude, time, date, overcast, fog, cloud occlusion, terrain occlusion, and object occlusion to calculate output values. The following features are included: * Air and Sea temperatures (array of numbers: °C) - llw_fnc_getTemperature * Date and time (text: YYYY-MM-DD hh:mm:ss) - llw_fnc_getDateTime * Shadow detection (boolean: true / false) - llw_fnc_inShadow * Solar Azimuth and Elevation angles (array of numbers: degrees) - llw_fnc_getSunAngle * Solar Elevation angle at 12:00PM (number: degrees) - llw_fnc_getSunElevationNoon * Solar Radiation energy (number: W/m²) - llw_fnc_getSunRadiation * Sunrise and Sunset time (array of numebers: hours) - llw_fnc_getSunRise Please refer to the enclosed README.TXT for further details. 17 2 Share this post Link to post Share on other sites

das attorney 858 Posted September 4, 2016 Doesn't look like it. I think there's already a function for that in the BIS library somewhere. Share this post Link to post Share on other sites
Grumpy Old Man 3545 Posted September 4, 2016 Doesn't look like it. I think there's already a function for that in the BIS library somewhere. Might be, made this back in the days: GOM_fnc_getWeekday = { params [["_date",date]]; _date params ["_year","_m","_q"]; _weekday = ""; _yeararray = _year call BIS_fnc_numberDigits; _yeararray params ["_y0","_y1","_y2","_y3"]; _J = (_y0 * 10) + _y1; _K = (_y2 * 10) + _y3; if (_m < 3) then {_m = _m + 12}; _hgreg = (_q + floor ( ((_m + 1) * 26) / 10 ) + _K + floor (_K / 4) + floor (_J / 4) - (2 * _J)) mod 7; _shortDayNames = ["Sat","Sun","Mon","Tue","Wed","Thu","Fri"]; _dayNames = ["Saturday","Sunday","Monday","Tuesday","Wednesday","Thursday","Friday"]; if ("SHORT" in _this) exitWith {_shortDayNames select _hgreg}; _dayNames select _hgreg }; Been using the climatological functions to great success! Very useful stuff! Edit: Fixed params error, use select instead multiple if thens (made this in the very beginnings of my A3 career) Cheers 1 Share this post Link to post Share on other sites
ceeeb 147 Posted September 4, 2016 Very nice, but no license? Also, noon is 12:00PM Share this post Link to post Share on other sites
fn_Quiksilver 1636 Posted September 5, 2016 Very nice, but no license? Also, noon is 12:00PM maybe he means solar zenith or "solar noon" but yea i am still trying to put together a function to convert date to day-of-week Share this post Link to post Share on other sites

fn_Quiksilver 1636 Posted September 5, 2016 Did you miss my spoiler? Cheers wow cool :) how did you arrive at this equation? _hgreg = (_q + floor ( ((_m + 1) * 26) / 10 ) + _K + floor (_K / 4) + floor (_J / 4) - (2 * _J)) mod 7; Share this post Link to post Share on other sites
Grumpy Old Man 3545 Posted September 5, 2016 Google, heh. Has quite a few sites covering this. Here's one of them. Updated my snippet in the spoiler above. Cheers 1 Share this post Link to post Share on other sites

Undeceived 392 Posted December 25, 2017 @Matthijs, these are some great and useful functions, thanks a lot! One question: The inShadow function does not work for moonlight, does it? I'm asking because I'm creating a mission where I want to change the camouflageCoef depending of the player being in the shadows (full moon) or running around in the plain fields. Any help would be much appreciated. 1 Share this post Link to post Share on other sites

Any help would be much appreciated. That is correct. The function was created to allow calculation of energy build-up in a body. It does this by calculating the position of the sun and checks for collissions between the body and the sun. (a rather CPU intensive thing I must admit) I did not account for moon, stars nor artificial light, because their energy radiation is negligible. Sorry...

Feint 137 Posted March 11, 2018 I used your sunAngle calculator function on my Depth Gauge Watch addon I just released. Thanks for making this. It allowed me to know when it make my depth gauge glow in the dark. :) Thanks again @Matthijs!! 4 1 Share this post Link to post Share on other sites

The Real Bunc 137 Posted May 27, 2019 Matthijs, I hope you are still around. You have two functions here ( inShadow and sun angle I think) that I was needing to create myself for my DynamicCamo script but that seems silly when as far as I can see you seem to have already done this. Any chance you could pm me or let me know on here how you feel about reuse etc (with full credits of course). This would not be me just using it personally but wrapping it up into a larger package. Wonderful functions btw. As an aside my first thought when when I saw you have a solar irradiance function was "agh , soon to be followed by working solar panels in Arma" lol! Great work.

Matthijs 40 Posted May 29, 2019 As per PM, feel free to re-use. Please be aware that the inShadow function is rather CPU intensive. Have fun! 4 1 Share this post Link to post Share on other sites
