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_auto
to 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

- Radius

Inputs
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 connected[todo tested in?]
OnGustEnd
- Fired when a wind gust ends.
