[Tutorial] Snow added to Dynamic Weather

Vampire · Dec 11, 2013

No I haven't, but if you take a look at the snow script included and think you could do it, that would be great.

Richie · Dec 12, 2013

Snow works perfectly

very nice script, thanks Vampire
Is there a way to change how much falls ? from a slight snow fall to a blizzard

Just play with
_minimumSnow
and
_maximumSnow.

That's the best you're going to be able to do with what there is at the moment.

Vampire · Dec 12, 2013

Working on getting the other snow to work with this and making progress.

I have the larger particles working, but its not quite right yet.

seaweeduk · Dec 13, 2013

Thanks for sharing this Vampire

I'm going to add some cold effects this week and get people hunting for heatpacks and fires when its snowing!

Have you thought about adding breath fog too? There's a few scripts for it like this one http://www.armaholic.com/page.php?id=13307

Vampire · Dec 13, 2013

I think I have implemented it into the script.
I have to do a test later.

zappi · Dec 13, 2013

Thak you Vampire, very nice work and atmosphere weather script.
Working great.
I looking forward for update about cold effect added

DangerRuss · Dec 14, 2013

so just heads up for anyone wondering.... the infinstar/blur antihack also interferes with setting custom temperature it seems. Also, if you're experiencing the crazy wind I think this is also caused by the antihack. What Ive noticed about the wind is its usually just one player or a couple players experiencing it. Relogging seems to correct the issue for anyone experiencing the issue.

you can do this yourself by extracting fn_temperatur.sqf from your dayz code to your server and calling it in your custom compiles

Inkko · Dec 20, 2013

I messed around with it a little bit, tried to merge the snow script everyone uses and couldn't get it to work. I increased the snow and added some color correction and film grain along with heavy fog and a shortened view distance when it snows tho. I've only tested it with snowchance set to 100% tho so I'll have to test how it looks when it changes to snowing.

DangerRuss · Dec 20, 2013

inkko I actually prefer my snow on 100% of the time so if you release this Id be interested. Although my antihack does tend to interfere with my weather/temperature unfortunately.

works nicely but the fog is way too thick for my pvp server. I like the idea though, scarier and all that. Just no visibility so you can't really engage AI or players.

You can lower the amount of fog, I got the ground fog from the other snow script working as well, but after it finishes snowing its stuck on. Plus when it changes to snowing its like a flash of darkness when it switches to color correction and the game fog instantly fills your view. I updated my above post with changes I've made for just snow, it needs work on transitioning between different types of weather.

Roger that, calling the fn_temperatur.sqf

But i suppose i have to edit it to add snow and fog effect isnt it?

adding snow and fog facor isnt enought i guess, what more to add?

Vampire · Dec 29, 2013

No, you don't need to add anything.

You just need to adjust the moving and fire factor down a point or two until you're happy with the effects in game.

zappi · Dec 29, 2013

Thank you mate.

I place the file into the server/compile and i call it from server_function.sqf like that?

fn_temperatur = compile preprocessFileLineNumbers "\z\addons\dayz_server\compile\fn_temperatur.sqf";

? is it right, i'm not sure

DangerRuss · Dec 29, 2013

I imagine if its like the dynamic weather you place it in a folder named whatever you want to call it (we'll call it custom), and in your compiles.sqf you call it something like this

Code:

execVM "custom\fn_temperatur.sqf";
initialized = true;

Of course you'd need to change your init.sqf to point to this custom folder and compiles.sqf

zappi · Dec 29, 2013

i used it in the test server.

I added it into the complie folder of the server and called like i wrote ^^^^^^

It seem working correctly

I will try to test trought the client side and call it like you do

DangerRuss · Dec 29, 2013

Im gonna try and get it to work on my server as well.. I think my antihack prevents it from working though... we'll see

It's not my antihack blocking it because I tried it after disabling the antihack. Maybe Im doing it wrong because its not working and its actually blocking my snow script from working as well.

Another interesting bit, even though I have the rained turned off in the dynamic weather, it definitely rains.
