Description

Description:

Smoothly change the fog over given time (in seconds). See also fogParams.

This command is MP synchronised, if executed on server, the changes will propagate globally. If executed on client effect is temporary as it will soon change to the server setting.

Multiplayer:

Pre-Arma 3, each client and the server could have different fog values

Syntax

Syntax:

time setFog fog

Parameters:

time: Number - transition time to the new value

fog: Number - fog density. Range 0..1

Return Value:

Nothing

Alternative Syntax

Syntax:

time setFog [fogValue, fogDecay, fogBase] Template:Since

Parameters:

time: Number - transition time to the new value

fogValue: Number - normal fog value that represents fog density at fogBase level. Range 0..1

fogDecay: Number - decay of fog density with altitude. Range -1..1

fogBase: Number - base altitude (ASL) of fog (in meters). Range -5000..5000

Return Value:

Nothing

Examples

Example 1:

15 setFog 0.5;

Example 2:

Force no fog: 0 setFog 0; // forceWeatherChange; // change is immediate 999999 setFog 0;

Example 3:

0 setFog [1, 0.01, 0];

Example 4:

Mountain fog, starts from 70m ASL and thickens more the higher you climb: 0 setFog [1, -1, 70];

Example 5:

Valley fog, starts from 60m ASL and thickens more the lower you descend: 0 setFog [1, 1, 60];

Example 6:

Fooooog on the waaaater: 0 setFog [1, 1, 0];

Only one script command induced weather change (either setOvercast or setFog) can be happening at a time. Starting a new weather change will immediately halt the current weather change. SetRain changes are independent and can occur simultaneously to a weather change.

setTimeMultiplier DOES affect transition time.

A little information about how Alt Syntax works. The fogValue is normal fog value that could be set independently with original setFog command. fogBase is the ASL altitude at which the fog will start. 0 is the sea level. fogDecay is how defined the fog start is. The more defined, the denser is the fog. 1 (or -1) are the max values. If it is positive the fog will be generated below fogBase line, if negative, above it. If fogDecay is small, the fog will transition more smoothly from no fog to full fog, and because of that it will cross fogBase line by quite a lot, depending on how small is fogDecay value. Current values of fogDecay and fogBase can be retrieved with fogParams
