Arma 3 Observation Night Sky [BETA]

 

This is some kind of example addon what can you do in Arma engine. Please do not ask me why some doen't work or why sometimes game crash.

 

Mod using own library which is helping calculate some data for satellites, because it cannot be done ingame.

 

WARNING!!!
When the library is called, it can connect to internet for downloading TLE data. These files are not dangerous for your PC, they only contains data for calculating satellites. Files are stored in @ObservationNightSky/tle.
Please if you don't know what are TLE data are, go to Wikipedia for more info.

 

 

Using mod

Module Satellites
This module add satellites into the game. Satellites are showed as white dots on night sky (as real satellites). If you point at them, info will display. If not, some issue happened, please it is BETA and only sample mod.

 

BEFORE PLACING MODULE, PLEASE SET INGAME REAL DATETIME. It means if it is today 2017-08-15, set this date also ingame. Otherwise game can crash or you can't see anything!

 

Also you can saw sometimes falling star (meteor). This is the next reason for setting right datetime, because meteor showers are calculated from real parameters.

 

On map you can see circle, bigger circle is the horizon. Smaller circle is 50 degrees of elevation.

 

 

Module Milky Way
This module simulates real Milky Way in night sky.
You can see three different brightness of it.
First is the maximum - for this brightness go to very dark place of map (without any light lamps) and set night without full moon.
Second is the middle - set night where is the moon at half
Third is the low - for this set night with full moon or go to city/town/village where are a lot of light lamps

Please, you can sometimes see that Milky Way texture is "misplaced". It is due to strange Arma stars positions, because they aren't at their real positions!

Also, Milky Way script was designed only for Altis and Startis, because script is dependent on lat lon coords.

 

 

Meteors and Bolides
These functions doesn't have scripts. If call it, it will run.

 

 

For meteor run:

[0, 50, 50, 0, 1] call ObservationNightSky_fnc_Meteor;

 

Parameters:
0 - azimuth ( 0 to 360 )
1 - elevation of start ( 30 to 90 )
2 - slope of fall ( 20 to 70 )
3 - from north or from south ( 0 or 1 )
4 - distance from player ( +1000 to -1000 )


For bolide run:

[0, 0, 50, 0, 1] call ObservationNightSky_fnc_Bolid;

 

Parameters:
0 - bolide type ( 0 - small long trail, 1 - small short trail, 2 - big and long trail )
1 - azimuth ( 0 to 360 )
2 - elevation of start ( 30 to 90 )
3 - from north or from south ( 0 or 1 )

Beautiful! Do you think there's a way to get the Milky Way working for other maps (obviously not correctly aligned to the other stars at the firmament) but it's just to cool to be missed.

Maybe.. I thought about new way how to calculate its position.

Hi Folks,

 

Nice work - pretty cool stuff - reminds me of camping out when a kid - trying to find satellites in the night sky - I was really skeptical at first but you can see them with the naked eye...

 

Regards,
Scott

Hi, this mod looks incredible! How would it work with servers? If it doesn't work, could this be a possible future feature?

It was created primary for singleplayer. There is no server key included. Well, I never tried it in MP, so I don't know if it works.

In future - maybe...

Bit of a bump, but what an awesome mod. One thing I might note about the Milky Way image used in this mod; there are at least two bright "stars" in that image that are not "stars"; the large yellow-spiked star, and the bright spot right next to the MW center. At least one of these is actually Jupiter, according to the original source: http://www.eso.org/public/usa/images/eso0932a/  

I believe there's a comet in there as well. Might be a fairly quick touchup to try and remove those.

 

Another interesting feature to add might be the zodiacal light; at the darkness levels where you can see the Milky Way in its full glory, the zodiacal light will be visible as well.

Thanks for ideas. As I like night observing night sky, I wanted to add all "night features" like zodiacal light. But due to my short of time I am still not able to add or fix current issues. Maybe if someone wants to continue, he can, but I for near future no.
