Random weather & Dynamic weahter.

[splatsh 10]

Where do I find any good script with random weather, like random fog, and random rain, and random time. (Everytime I start mission it should not be the same weather & time.)

Where do I find dynamic weather change, example that weather cheange every hour or so... start to rain, more fog, less rain, less fog and so on.

Would nice if there is something like that.

Thanks.

Hi,

that's quite easy, as rain and fog intensity are values between 0 and 1, all you have to do is generate a random value between 0 and 1 thanks to the "random" command, such as :

60 setRain random 1

where "60" is the number of seconds of the transition.

See also setfog and setOvercast.

Then, a very simple script to launch these parameters again every hour for example for dynamic weather.

[splatsh 10]

Yeah, that looks easy, thanks =)

This is what I got in my init.sqf now:

skipTime (random 24);

60 setRain random 1;

60 setFog random 1;

Clayman wrote a great weather script. Have a look here or download it from here. You can set different parameters like daytime, nighttime and weather type.

Thanks, that looks cool and heavy.

How do I use it?

Copy & paste to my init.sqf file?

And how do I run it with diffrent settings?

(My german is not that good, and I did not find any read me.)

I found something....

Is this right?

I have paste this code into my init.sqf file:

[6, 8, 20, "Mixed"] execVM "weather.sqf";

Try this..it's very easy to use and you get some great weather FX's.

That script does not work with Arrowhead sadly..

If you do it yourself, the biggest two gotcha's are:

1) The commands setFog and setOvercast can't be used simultaneously. You have to do them "in steps" or wait for one to finish before doing the other.

2) The command setRain will immediately be overrun by whatever the engine thinks is suitable. That makes it hard to get steady rain, light rain at heavy overcast, or heavy rain a low overcast. Luckily setRain can be used whenever you feel like it (while setFog or setOvercast is adjusting), so you can set a quick loop to hold whatever rain level you want.

Fully random weather scripts has never been good to me. I typically need i.e. weather on the nice side, where rain and fog is quite rare. Also I have to this date never found max fog level to be playable at all, which is what most weather scripts tend to use.

Finally, wind can be set using setWind [10,3,true] instead of relying on overcast (which seems to be the normal driving force), where 10 and 3 are the wind vectors.

If you download external script, make sure the mission is playable with whatever extreme values the script allows. Experiment with how bad weather you can allow while still having a playable mission, and put those values in the script as the extreme values. Keep in mind that normally, 50% fog (which is a lot in the game) is far above "normal" levels of fog. Consider a squared (as a minimum) distribution of the randomness, instead of linear chances.

Doesn't work for me, did you find a fix?

English Version^^

Wetterscript V1.3:

With this script you can create random weather.

There are several optional parameters to adjust the weather settings.

_initial: If set to true, random settings for weather will be generated at mission start. If you want specific weather at the beginn of the mission, and random weather to start later, set this to false. (Default: true)

_startDawn: Determines the daytime when dawn beginns. Value from 0 to 24. (Default: 05:00)

_endDawn: Determines the daytime when dawn ends. Value from 0 to 24. (Default: 07:00)

_nightTime: Determines the daytime when night beginns. Value from 0 to 24. (Default: 20:00)

_weatherType: Here you can select the kind of weather. (Default: "Mixed") Possible values (See header of script for details):

"Good"

"Average"

"Bad"

"Mixed"

"MediumGood"

"MediumBad"

"Custom"

The following parameters are only required for _weatherType "Custom":

_customMinOvercast:

_customMaxOvercast: You can pass values for min and max overcast, e.g. best and worst possible weather. Values must be between 0 and 1, where 0 is clear sky and 1 is heavy rain / storm.

_customMinFog:

_customMaxFog: Same as above, only for the fog. 0 is no fog, 1 is thick fog.

There are four different ways to call the script. Examples:

Call without parameter:

0 = [] execVM "randomWeather.sqf"

Call with only one parameter:

0 = [false] execVM "randomWeather.sqf"

Call with five parameters:

0 = [true, 4.5, 6.5, 19.5, "Average"] execVM "randomWeather.sqf";

Call for "Custom" weathertype with nine parameters:

0 = [false, 6, 8, 18, "Custom", [0.4, 0.6], [0.2, 0.5]] execVM "randomWeather.sqf";

And here is the script:

randomWeather.sqf

/********************************************************************************

  randomWeather.sqf

  Script by Clayman

  Version 1.3


  Optional Parameters:

  [<_initial | Bool>, <_startDawn | Number>, <_endDawn | Number>, <_nightTime | Number>, <_weatherType | String>, [<_customMinOvercast | Number>, <_customMaxOvercast | Number>], [<_customMinFog | Number>, <_customMaxFog | Number>]]

  _initial:   Should random weather be set initially.
        If you want specific weather at mission start and the random weather to start later, set this to false.
        If you start script at mission start, set this to true, so random values for starting weather will be used.

  _startDawn:    Sets the time (0-24) when dawn beginns (default: 05:00)
  _endDawn:    Sets the time (0-24) when dawn ends (default: 07:00)
  _nightTime:    Sets the time (0-24) when the night starts (default: 20:00)
  _weatherType:   Sets what kind of weather there will be: (default: "Mixed")

              "Good":
           Clear sky to light clouds
           None to light fog during day and night
           Medium to thick fog during dawn
           No rain

              "Average":
           Cloudy sky
           Light to medium fog during day
           Light fog during night
           Light to medium fog during dawn
           No rain

              "Bad":
           Dark clouds
           Medium to thick fog during day
           Light to medium fog during night
           No fog during heavy rain / storm
           Light rain to storm

              "Mixed":
           All of the above can be possible

              "MediumGood":
           Mix of 'Good' and 'Average' weather types

              "MediumBad":
           Mix of 'Average' and 'Bad' weather types

              "Custom":
           Set values for min and max overcast
           Set values for min and max fog
           Slightly more fog during dawn
           Slightly less fog during night
           No fog during heavy rain / storm

  _customMinOvercast:
  _customMaxOvercast:
        Additional parameters for "Custom" weather.
        Sets the minimum and maximum overcast values (0 = clear sky, 1 = storm)

  _customMinFog:
  _customMaxFog:
        Additional parameters for "Custom" weather.
        Sets the minimum and maximum fog values (0 = no fog, 1 = thick fog)


  Examples:

  No parameters - default settings will be used:

     0 = [] execVM "randomWeather.sqf";

  Only parameter for initial setting:

     0 = [false] execVM "randomWeather.sqf";

  Parameters for preset weather types:

     0 = [true, 4.5, 6.5, 19.5, "Average"] execVM "randomWeather.sqf";

  Parameters for custom weather settings:

     0 = [false, 6, 8, 18, "Custom", [0.4, 0.6], [0.2, 0.5]] execVM "randomWeather.sqf";



  To end the script, set global variable 'CLAY_Weather' to false

That's fantastic! Thank you very much. This gives so much to immersion I don't know why anyone would not use it.

I guess this is related to the engine and its inner workings, but shouldn't it become a lot darker when i rains? I mean really dark?

Thanks again, two thumbs up!
