Entity Description

An entity that spits out a constant stream of smoke. You can place up to two env_particlelight entities near the smoke stack to add ambient light to its particles.

Availability

This point-based entity is available in: all Source games. In code it is represented by class CSmokeStack, defined in smokestack.cpp.

Keyvalues

• Targetname:

• InitialState

<boolean>

• BaseSpread

<float> Amount of random spread in the origins of the smoke particles when they're spawned.

• SpreadSpeed

<integer> Amount of random spread in the velocity of the smoke particles after they're spawned.

• Speed

<integer> The speed at which the smoke particles move after they're spawned.

• StartSize

<float> Size of the smoke particles when they're first emitted.

• EndSize

<float> Size of the smoke particles at the point they fade out completely.

• Rate

<integer> Rate at which to emit smoke particles (i.e. particles to emit per second).

• JetLength

<integer> Length of the smokestack. Lifetime of the smoke particles is derived from this & particle speed.

• WindAngle

<integer> This specifies the wind direction. It is an angle in the XY plane. WindSpeed specifies the strength of the wind.

• WindSpeed

<integer> The strength of the wind.

• SmokeMaterial

<material> Material of the smoke particles emitted by this stack.

• twist

<float> The amount, in degrees per second, that the smoke particles twist around the origin.

• rendercolor

<color255> Base Color

• renderamt

<integer> Translucency

• roll

<float> Amount of roll in degrees per second.

Inputs

• Targetname:

• TurnOn

Turn on the smokestack.

• TurnOff

Turn off the smokestack.

• Toggle

Toggles the smokestack between on and off state.

• JetLength <float>

Set the length of the smoke trail.

• Rate <float>

Set the rate at which to emit smoke particles (particles per second).

• Speed <float>

Set the speed at which the smoke particles move after they're spawned.

• SpreadSpeed <float>

Set the amount of random spread in the velocity of the smoke particles after they're spawned.
