[Tutorial] Snow added to Dynamic Weather

[Vampire]

So I was wondering how to add snow to the dynamic weather like everyone else, and then realised that snow was dynamic on Namalsk. So I looked at how it was done, and seen that Namalsk uses a custom dynamic weather script with snow as a logic function. Thought I was crazy for trying but I managed to get it working on my Epoch server.

All credits go to Sumrak (http://www.nightstalkers.cz/) for putting so much work into Namalsk.​

All this code is his, I simply figured out how to port it from Namalsk to any map.​

First create a folder in your mission.pbo called Weather, and put these two scripts in there:​

Hit "RAW" next to download, to copy and paste.​

First script: DynamicWeatherEffects.sqf​

(You can modify the settings at the top, but it only snows if it's over .75 overcast)​

Hit "RAW" next to download, to copy and paste.
Second script: fn_dzn_snowfall.sqf
(This script even takes into account if you are inside a building, so it doesn't snow inside)
http://pastebin.com/nmmFrJyZ

Then you need to open up your init.sqf (on Epoch) or custom compiles and point the dynamic weather location to your script instead.
Like so:

        //Start Dynamic Weather
    execVM "Weather\DynamicWeatherEffects.sqf";

When the script wants it to snow, it calls the snow function, which runs the script. We need to add the snow function.

Open your Description.ext
Under the class RscPicture block of code, add this.

class CfgFunctions {
    class DZN {
        class Functions {
            class snowfall {
                description = "Simple snowfall script";
                file = "Weather\fn_dzn_snowfall.sqf";
            };
        };
    };
};

In the DynamicWeather I have Debug turned on. Turn it off if you don't want it logging the current weather to your .RPT.

Enjoy everyone!

If someone could modify the fn_dzn_snowfall.sqf to use the snow from the other snow script everyone is using, that would be great.

The Namalsk snow is nice, but it's not dense enough for my liking.

 

[Andrew_S90]

Very cool! I like the snow idea, the idea of a winter chernarus would be awesome

 

[Vampire]

There is a classname for snow, but to cover your entire map in it would be too much. Maybe some code to spawn patches of it accross the map?

 

[Stuff and Junk]

Glad to see someone else figured this out. I just added the snow to my fixes folder and changed the line to call it. Didnt have to mess with anything else :/

 

[Stuff and Junk]

Also i dont know if u have this in your scripts but you can make the cold affect players temps and also put in warm clothing like we did.

 

[Hertizch]

Great!
Would be fun to get the groundfog to work dynamically as well, like when overcast is over 0.5 for example.

 

[Vampire]

You cant add new skins to a mod unless you make a new mod.
You can adjust the tempurature by adjusting fn_temperatur.sqf

 

[Stuff and Junk]

i didnt add skins i defined existing ones as warm clothing.

 

[Vampire]

Oh I see.

You would probably just code into fn_tempuratur.sqf that if the player model matches those in an array then the overall temperature is higher

 

[graeme bourne]

i didnt add skins i defined existing ones as warm clothing.

Some info on that would be awesome, if your willing to share

Thnx in advance

[Hertizch]

You need some new variables, for example:

Factors:
_warm_clothes = 10;

And for posistive effects:
if (((typeOf player) == "Sniper1_DZ")) then {
_difference= _difference + _warm_clothes;
};

I guess that will work

 

[SteveJ]

I think it's buggy. Wind is too hard

 

[Hertizch]

Hahaha! The storm is coming!
You obviously messed up somewhere

 

[SteveJ]

IDK, but I did everything as in the tutorial. The only thing I have added a script to clean weather at certain times of day. Like this in DynamicWeatherEffects.sqf

if(daytime<6||daytime>19)then {
        _currentOvercast = 0;
        _currentFog = 0;
        _currentRain = 0;
        _currentWeatherChange = _this select 3;
        _targetWeatherValue = _this select 4;
        _timeUntilCompletion = _this select 5;
        _currentWindX = _this select 6;
        _currentWindZ = _this select 7;
    }
    else {
    _currentOvercast = _this select 0;
    _currentFog = _this select 1;
    _currentRain = _this select 2;
    _currentWeatherChange = _this select 3;
    _targetWeatherValue = _this select 4;
    _timeUntilCompletion = _this select 5;
    _currentWindX = _this select 6;
    _currentWindZ = _this select 7;
    };

 

[SteveJ]

And there is error in RPT:
"0:0 Debug: Starting script WeatherEffects.sqf..."

16:12:27 Error in expression <ndZ, true];
 
 
if (_currentWeatherChange == "OVERCAST") then {
_timeUntilCompleti>
16:12:27  Error position: <== "OVERCAST") then {
_timeUntilCompleti>
16:12:27  Error Generic error in expression
16:12:27 File mpmissions\dayz_1.Chernarus\Fixes\compile\DynamicWeatherEffects.sqf, line 191

 

[Hertizch]

Yeah, have to be something with your own edits because for me it's working like it should, without hurricanes!

 

[DangerRuss]

Would there be away to make it so it only snows, never rains?

 

[Hertizch]

Just set rain min and max to 0

 

[Vampire]

Don't change the amount, just change snow chance to 100% and rain to 0.
These lines:

_rainIntervalRainProbability = 50;
_snowIntervalSnowProbability = 50;
