env_wind is a point entity available in all 
Source games. It creates wind throughout an entire map, which affect physics props and swaying trees.
Important:This is a preserved entity in 
.
- On a new round entities with this classname will intentionally not reset. You can use
logic_autoto emulate resetting it. - Killing it removes it forever, as it is not respawned on a new round.
- It cannot be spawned with a
point_template. - Parenting this with non preserved entities may have undesirable effects.
Note:Wind direction is determined by env_wind's yaw value.Note:In most games, this entity is required for $treesway to have any effect, unless $treeswaystatic (only in 
) is used.
Bug:The wind effect in the client game will not reset when a new map is loaded which does not contain an env_wind entity. [todo tested in?]
Tip:In 
Black Mesa this entity can be spawned via point_template and killed with Kill input. This allows you to change the wind globally or turn it off completely by spawning new env_wind and killing via Kill input the previous env_wind.Keyvalues
- Name
(targetname)<string> - The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g.
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- 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- Fired when a wind gust ends.
