Random snow effect

Nvdm · Nov 14, 2013

Hey!

I have seen many threads about adding the snow effect. But it is either on or off. I want it to be more random. So I have made a start with some scripts to make it more random. It will probably need some more work, but I hope you guys want to help finish the script.

Here is what I have so far:

Snowcheck.sqf is executed in your missions init.sqf file.

snowcheck.sqf

Code:

// Script executed every 5 minutes to check random snow effect.
 
snowcheck = true;
 
while {snowcheck} do {
nul = [] execVM "random_snow.sqf";
sleep 300;
};

random_snow.sqf

Code:

// Script to check by a random variable if it should snow or not.
 
snowchance = round(random 100);
 
if (snowchance > 70) then {
snow = [] execVM "spawn_snow.sqf";
}
else
{
terminate snow;
};

spawn_snow.sqf

Code:

// Script to create the snow effect.
 
//Snow Storm
//Modified by Audio Rejectz, all credits go to original creators JW - Snow script / BI - Wind & Dust particles
"filmGrain" ppEffectEnable true;
"filmGrain" ppEffectAdjust [0.02, 1, 1, 0.1, 1, false];
"filmGrain" ppEffectCommit 5;
 
stormchance = (random 100);
 
if (stormchance > 1) then {
setviewdistance 600;
bis_fog = 1;
0 setovercast 1;
}
else {
setviewdistance 1000;
bis_fog = 0.6;
};

0 setfog bis_fog;

    _delay = 3;
    sleep 0.01;

cant you just tie it in with dynamic weather script ?

what I mean is,

Ive modded my dynamic weather scripts so it does its normal stuff during daylight hours.
Then it has clear, no overcast skies at night.

I was thinking is it possible to merge the script in with it.

Vampire · Nov 14, 2013

If you already have dynamic weather in your mission pbo this should add dynamic snow.

It'll be a 1/4 chance when it rains to snow instead.

Change (line 14ish)

Code:

private ["_minimumFog", "_maximumFog", "_minimumOvercast", "_maximumOvercast", "_minimumRain", "_maximumRain", "_minimumWind", "_maximumWind", "_minRainIntervalTimeMin", "_maxRainIntervalTimeMin", "_forceRainToStopAfterOneRainInterval", "_maxWind"];

to this

Code:

private ["_minimumFog", "_maximumFog", "_minimumOvercast", "_maximumOvercast", "_minimumRain", "_maximumRain", "_minimumWind", "_maximumWind", "_minRainIntervalTimeMin", "_maxRainIntervalTimeMin", "_forceRainToStopAfterOneRainInterval", "_maxWind","_snowCheck"];

Add this

Code:

// Turn snow on or off (on = true, off = false)
_snowCheck = true;

under

Code:

// The following variables can be changed to tweak weather behaviour

Change (around line 472)

Code:

private ["_rainTimeSec"];

to

Code:

private ["_rainTimeSec","_snowDucksArray","_snowGoose"];

Add this:

Code:

_snowDucksArray = ["duck", "duck", "goose", "duck"];
                        _snowGoose = _snowDucksArray select floor random count _snowDucksArray;
                        if ((_snowGoose == "goose") && _snowCheck) then {
                            // It's not raining this time
                            drn_var_DynamicWeather_rain = 0;
                            publicVariable "drn_var_DynamicWeather_rain";
                           
                            // Make it snow instead
                            dynSnow = [] execVM "missionfoldername\snow.sqf";
                           
                        };

Under

Code:

else {
                            drn_var_DynamicWeather_rain = 0;
                            publicVariable "drn_var_DynamicWeather_rain";
                           
                            _forceStop = false;
                        };

And add

Code:

                        // If its snowing, kill it
                        terminate dynSnow;

Under

Code:

                    if (drn_var_DynamicWeather_rain != 0) then {
                        drn_var_DynamicWeather_rain = 0;
                        publicVariable "drn_var_DynamicWeather_rain";

If it is over .75 overcast and it chooses to rain, it has a 1/4 chance of snowing instead.

Vampire · Nov 14, 2013

Make sure you change

Code:

dynSnow = [] execVM "missionfoldername\snow.sqf";

to point to the snow.sqf in your mission pbo

Vampire · Nov 14, 2013

Thinking about it I think this

Code:

// If its snowing, kill it
terminate dynSnow;

Needs to be

Code:

// If its snowing, kill it
if (!(isNil(dynSnow))) then {
terminate dynSnow;
};

I am going to try it out now.

Vampire · Nov 14, 2013

I've added it to my server, and I'm getting no log errors so far after about 3 hours, but it may not have ran yet, and I haven't been on to see if it ever snowed.

With my Antihack I can set it to storm. Maybe it has a high chance of snowing then. With lots of overcast.

Vampire · Nov 14, 2013

As long as it's over .75 overcast and decides to rain then it has a 1/4 chance to snow instead.
Your antihack might just be turning on rain, which won't make a difference. It has to run from the dynamic script.
You might be able to adjust the dynamic to turn up the chance of rain, but I'll just wait and see for mine.

Reason I'm wondering is because none of my script I added will run unless it rains.
I guess I could ask my players later tonight if it snowed at all.

Vampire · Nov 15, 2013

After testing this It needs to be ran from the client side. So the dynamic weather will need to use a global variable to say it's on, and then have a script called from the init wait until its called, and terminate it when it's done.

Working with it now.

I see. Did the snow script get executed at all? Or was there no snow effect?

Vampire · Nov 15, 2013

I never seen the snow effect. Modified my dynamic weather to run it 24/7 and it still never showed up, so I blieve it's an issue with the dynamic weather being executed server side instead of client side (from the init)

I tried to make the dynamic weather throw out a global variable and have the script running from the init catch it, but I don't think they dynamic weather script runs often enough to loop through and keep updating itself.

I'm at a loss on where to go from here. I guess keep working on your script on randomizing the snow until someone can come along and figure out how to correctly execute what I was attempting to do.

I have also created the topic on the epoch forums. Somebody also had an idea how to execute:

Vampire · Nov 15, 2013

Yes he is correct too. You can probably pretty easily use a script like yours to randomize it, but until it is added to the dynamic weather it isn't dynamic. It would be snow or no snow.

Did the script you post work?

SchwEde · Nov 15, 2013

hey,

I'm also interesseted to get this working for the winter on my server. Sadly for now on the testing-phase no results:

here is dynamic-weather.sqf (some values i haev changed for testing the snow)
http://pastebin.com/Eq4LLx3q

and here is my snow.sqf:
http://pastebin.com/JuLn59sZ

Thanks for any idea

Cheers

I havent tested it yet. But I think that could work. Just make it execute it every 15 minutes with a chance on snow. I think the problem lies in stopping the snow.

Vampire · Nov 15, 2013

You would need to set the ppEffect to false, and then delete all the snow vehicles.
