trigger_wind is a brush entity available in all Source Source games. It is a trigger that pushes physics objects that touch its volume.

Warning.pngWarning:Clientside prop_physics aren't detected by this entity. Use Force server-side flag of such prop_physics if this is an issue.

Keyvalues

Name (targetname) <string>[ Edit ]
The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.
See also:  Generic Keyvalues, Inputs and Outputs available to all entities

Speed (speed) <integer>
The baseline for how hard the wind blows.
Speed Noise (SpeedNoise) <integer>
Noise added to wind speed +/-
Pitch Yaw Roll (Y Z X) (angles) <angles>
Yaw sets the wind direction. Pitch and roll should be ignored.
Warning.pngWarning:Brush also gets rotated but it's not shown in hammer
PlacementTip.pngWorkaround:If Vscripts with NetProps functions are available then instead of using angles keyvalue create logic_auto that OnMapSpawn sends RunScriptCode input to trigger_wind with parameter. (45 yaw in this example) 
foreach(k,v in {m_nDirBase=45}) NetProps.SetPropInt(self,k,v)
Direction Noise (DirectionNoise) <integer>
Noise added to wind direction.
Hold Time (HoldTime) <integer>
Baseline for how long to wait before changing wind.
Hold Noise (HoldNoise) <integer>
Noise added to how long to wait before changing wind.
Filter Name (filtername) <filter>
Name of filter entity to test against activators.
Start Disabled (StartDisabled) <boolean>
Stay dormant until activated (with theEnableinput).

Flags

Needs one of these flags checked to work.


Physics Objects : [8]
Everything (not including physics debris) : [64]

Inputs

SetSpeed <integerRedirectInput/integer>
Set the baseline for how hard the wind blows.

EnableDisable:

Enable / Disable
Enable/disable this entity from performing its task. It might also disappear from view.
Icon-Bug.pngBug:Sometimes props that are inside this trigger's brush and are asleep won't be detected after Enable input.
Note.pngFix:Send Wake input to all the desired props.
  (tested in: l4d2)
