env_wind is a point entity available in all 
Source games. It creates wind throughout an entire map, which affect physics props, swaying trees, and dust.

parentnameortarget).
Also displayed in Hammer's 2D views and Entity Report.See also: Generic Keyvalues, Inputs and Outputs available to all entities
- Min normal speed (minwind) <integer>
- Minimum speed of the wind while idling.
- Max normal speed (maxwind) <integer>
- Maximum speed of the wind while idling.
- Min gust speed (mingust) <integer>
- Minimum speed of wind gusts.
- Max gust speed (maxgust) <integer>
- Maximum speed of wind gusts.
- Min gust delay (mingustdelay) <integer>
- Minimum time delay between random gusts.
- Max gust delay (maxgustdelay) <integer>
- Maximum time delay between random gusts.
- Gust Duration (gustduration) <integer>
- How long will the wind gust for.
- Max gust dir change (degrees) (gustdirchange) <integer>
- Maximum amount that the wind's direction changes due to a gust.
- Radius (windradius) <float> (only in )
- The radius this entity applies wind effects to. -1 for global effect.
Inputs
- Enable (only in
) - Turns the wind on.
- Disable (only in )
- Turns the wind off.
Outputs
- OnGustStart
- !activator = !caller = NULL
Fired when a wind gust begins. - Bug:env_wind gusts can seemingly pile up and fire this output multiple times when a player first loads into a multiplayer map.
Workaround:Use AddOutput to add OnGustStart effects when players are already connectedTodo: Needs more testing, only observed in[todo tested in ?]
- OnGustEnd
- !activator = !caller = NULL
Fired when a wind gust ends.
