Entity Description

An invisible light source that changes over time. Can be turned on and off through inputs, and can aim at any object, including moving ones. Dynamic lights are calculated on the fly in the game, which means they have a higher processing cost but are much more flexible than static lighting.

Note:This entity actually consists of two lights, a cone model light and a spot world light. Some values may affect one and not the other.
Note:For the light to work properly the "distance" keyvalue must be greater than the distance from the entity to the surface it is supposed to light, otherwise it will not show. Also, the "brightness" keyvalue should be either 6 or 8, normal brightness values do not apply. Finally, adjusting the angle using the circle tool in the top-right or by using the "point at" tool will only adjust the cone model, the angle keyvalue must be set manually to adjust the spot world light.

Keyvalues

  • Targetname:

Name <string>
The targetname other entities refer to this entity by.

  • Angles:

Pitch Yaw Roll (Y Z X) <angle>
This entity's angular orientation in the world.
This will control the direction the light points at, if no target is specified.

  • Parentname:

Parent <targetname>
Specifies the targetname of this entity's movement parent. Entities with parents move with their parent.
  • target <target_destination>
The name of an entity in the map that the dynamic light will point at.
  • inner_cone <integer>
The inner (bright) angle.
  • cone <integer>
The outer (fading) angle.
  • brightness <integer>
This is the intensity of the spotlight.
  • spotlight_radius <float>
This is the radius of the spotlight, in inches, at the object that it is hitting.

Flags

  • 1 : No World Light
  • 2 : No Model Light
  • 4 : Add Displacement Alpha
  • 8 : Subtract Displacement Alpha

Inputs

  • Targetname:

Kill
Removes this entity from the world.
KillHierarchy
Removes this entity and all its children from the world.
AddOutput <string>
Evaluates a keyvalue/output on this entity. It can be potentially very dangerous, use with care.
Format: <key> <value>
Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>
FireUser1 to FireUser4
Fire the OnUser outputs; see User Inputs and Outputs.

  • Parentname:

SetParent <targetname>
Move with this entity. See Entity Hierarchy (parenting).
SetParentAttachment <string>
Attach to a named attachment on the current parent. The entity will teleport so that the position of its root bone matches that of the attachment.
SetParentAttachmentMaintainOffset <string>
As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.
ClearParent
Removes this entity from its current movement hierarchy.
  • Brightness
<integer> Set the light brightness.
  • Distance
<float> Set the maximum light distance.
  • _inner_cone
<integer> Set the inner (bright) angle.
  • _cone
<integer> Set the outer (fading) angle.
  • spotlight_radius
<float> Set the radius of the spotlight at the end point.
  • style
<integer> Change the lightstyle (see Appearance field for possible values).
  • TurnOn
Turn the light off.
  • TurnOff
Turn the light on.
  • Toggle
Toggle the light on/off.
