Description

Description:

Sets rain density smoothly over the given transition time. A transition time of zero means an immediate change. A rain density of zero is no rain, one is maximum rain. Rain is not possible when overcast is less than 0.7.

Since Arma 3 this command is multiplayer synchronised:

if executed on the server, the changes will propagate globally.
if executed on a client, the effect is local, temporary and will soon change to the server setting.

Minimum overcast needed for rain in Arma 3 is 0.5.

⚠

Alternative syntaxes (Syntax 2 and Syntax 3):

set rain particle params. Rain particles params are client-side params and are ignored on dedicated server. Use helper function BIS_fnc_setRain if sync is needed in Multiplayer
have a local LELocal effect

Multiplayer:

Prior to Arma 3, each client and the server could have different rain values.

Groups:

Environment

Syntax 1

Syntax:: time setRain rain
Parameters:: time: Number - transition time in seconds to the new value
: rain: Number - new rain value in range 0..1.
Return Value:: Nothing

2.08

Syntax 2

Syntax:: LELocal setRain rainParams
Parameters:: rainParams: Array - array of custom RainParticles params - see rainParams. Use empty array [] to reset to default config values
Return Value:: Nothing

2.08

Syntax 3

Syntax:: LELocal setRain config
Parameters:: config: Config - config path to a custom class, which contains RainParticles class. Use configNull to reset to default config values
Return Value:: Nothing

Examples

Example 1:: 60 setRain 1;
Example 2:: Force no rain:
0 setRain 0; forceWeatherChange; 999999 setRain 0;
Example 3:: Snow like effect (Since Arma 3 v2.08):
0 setOvercast 1; 0 setRain 1; 0 setFog 0.1; // snow affects visibility at distance setHumidity 0.9; // don't want to see dust clouds enableEnvironment [false, true]; // don't want to see snakes and butterflies either forceWeatherChange; setRain [ "a3\data_f\rainnormal_ca.paa", // rainDropTexture 1, // texDropCount 0.01, // minRainDensity 15, // effectRadius 0.1, // windCoef 2, // dropSpeed 0.5, // rndSpeed 0.5, // rndDir 0.02, // dropWidth 0.02, // dropHeight [0.1, 0.1, 0.1, 1], // dropColor 0.1, // lumSunFront 0.1, // lumSunBack 5.5, // refractCoef 0.3, // refractSaturation true, // snow false // dropColorStrong ];

: setTimeMultiplier does not affect transition time.

: Using Example 2 on dedicated server might need additional interference on JIP clients. The reason is that JIP has rain value > 0 slowly changing to 0. To force client to sync one can execute this on client:
skipTime 1; skipTime -1;
