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

Warning: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:Brush also gets rotated but it's not shown in hammer

Workaround: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.

Bug:Sometimes props that are inside this trigger's brush and are asleep won't be detected after Enable input.

Fix:Send Wake input to all the desired props.
