Make it snow on your server

[Audio Rejectz 144]

A few people have been asking for this, so thought id make a fresh post as the other one wasn't specifically aimed at this. PLEASE NOTE - in doing this you will need to change a few of your scripts as BE will kick for script rescription #21 and i think one more. You will need to edit these to let people join

Anyway. here it is.

Open your mission file and create a file called effects.sqf and then put in the code below

effects.sqf

_dpos = [((_pos select 0) + (_d - (random (2*_d))) + ((velocity vehicle player select 0)*1)),((_pos select 1) + (_d - (random (2*_d))) + ((velocity vehicle player select 0)*1)),((_pos select 2) + _h1)];
drop ["\ca\data\cl_water", "", "Billboard", 1, 7, _dpos, [0,0,-1], 1, 0.0000001, 0.000, 0.7, [0.07], [[1,1,1,0], [1,1,1,1], [1,1,1,1], [1,1,1,1]], [0,0], 0.2, 1.2, "", "", ""];


_dpos = [((_pos select 0) + (_d - (random (2*_d))) + ((velocity vehicle player select 0)*1)),((_pos select 1) + (_d - (random (2*_d))) + ((velocity vehicle player select 0)*1)),((_pos select 2) + _h2)];

};
sleep 0.2;
};

Then in your ini file put this:

// SnowStorm:
if (!isDedicated) then {
[] execVM "effects.sqf";
};

There you go

Please note that the way i have this set up is for quite an extreme storm, it really adds some tense moments not being able to see people within a few hundred meters

If you want just the snow, and not the effect i use then delete this from the top code

setviewdistance 900;
bis_fog = 0.8;

setviewdistance 900;
0 setovercast 0.9;
0 setrain 1;
//0 setfog 0.8;
0 setfog bis_fog

Or you can play with the settings to your likeing, setfog 1 is max fog, where as setfog 0 is obviously nothing. The reason i setview distance to 900, is to add performance. As on our server you cant see that far anyway

On another note - If you would like to force your sever to have no fog at all, and let people see over 6000 meters, put this into the effects ini

setviewdistance 9000;
bis_fog = 0;

setviewdistance 9000;
0 setovercast 0;
0 setrain 1;
//0 setfog 0;
0 setfog bis_fog

With the settings above, there will be no fog AT ALL, it wont ever rain and will always be clear skies.

Once you made all your changes, pack it all back into a pbo and all done

Hope this helps

It snows in vanilla ArmA 2/OA if you set the date to January or December and make it crappy weather.

Yeah i know mate, all though that's not an option for most Dayz users. So wanted to give them the option to have something fitting for the time of year :D
