Source(core) Point Entity

description

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

properties

• Parent parentname(target_destination)
  The name of this entity's parent in the movement hierarchy. Entities with parents move with their parent.
• Pitch Yaw Roll (Y Z X) angles(angle) - default: 0 0 0
  This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.
• Name targetname(target_source)
  The name that other entities refer to this entity by.
• Initial State InitialState(choices)
  • 0 - Off
  • 1 - On
• Spread at the base BaseSpread(integer) - default: 20
  Amount of random spread in the origins of the smoke particles when they're spawned.
• Spread Speed SpreadSpeed(integer) - default: 15
  Amount of random spread in the velocity of the smoke particles after they're spawned.
• Speed Speed(integer) - default: 30
  The speed at which the smoke particles move after they're spawned.
• Particle start size StartSize(integer) - default: 20
  Size of the smoke particles when they're first emitted.
• Particle end size EndSize(integer) - default: 30
  Size of the smoke particles at the point they fade out completely.
• Emission rate Rate(integer) - default: 20
  Rate at which to emit smoke particles (i.e. particles to emit per second).
• Length of smoke trail JetLength(integer) - default: 180
  Length of the smokestack. Lifetime of the smoke particles is derived from this & particle speed.
• Wind X/Y Angle WindAngle(integer) - default: 0
  This specifies the wind direction. It is an angle in the XY plane. WindSpeed specifies the strength of the wind.
• Wind Speed WindSpeed(integer) - default: 0
  The strength of the wind.
• Particle material SmokeMaterial(string) - default: particle/SmokeStack.vmt
  Material of the smoke particles emitted by this stack.
• Twist twist(integer) - default: 0
  The amount, in degrees per second, that the smoke particles twist around the origin.
• Base Color (R G B) rendercolor(color255) - default: 255 255 255
• Translucency renderamt(integer) - default: 255

spawn flags

none.

inputs

• SetParent(string)
  Changes the entity's parent in the movement hierarchy.
• SetParentAttachment(string)
  Change this entity to attach to a specific attachment point on it's parent. Entities must be parented before being sent this input. The parameter passed in should be the name of the attachment.
• ClearParent(void)
  Removes this entity from the the movement hierarchy, leaving it free to move independently.
• TurnOn(void)
  Turn on the smokestack.
• TurnOff(void)
  Turn off the smokestack.
• Toggle(void)
  Toggles the smokestack between on and off state.
• JetLength(integer)
  Set the length of the smoke trail.
• Rate(integer)
  Set the rate at which to emit smoke particles (particles per second).
• Speed(integer)
  Set the speed at which the smoke particles move after they're spawned.
• SpreadSpeed(integer)
  Set the amount of random spread in the velocity of the smoke particles after they're spawned.

outputs

none.
