Beam spotlight.png
beam_spotlight is a point entity available in all Source games. It is used to draw a spotlight. Will draw a beam when the player views it side on, and a halo when it's facing towards the player. Unless the 'No Dynamic Light' spawnflag is checked, it will also create a dynamic light wherever the end of the spotlight rests. Other than its ability to rotate, this entity is functionally identical to point_spotlight.

This spotlight is entirely client side, it is not sync'd across clients.

Tip:Can be set to rotate for a lighthouse search beam effect.

Keyvalues

Max Rotation Speed <integer>
The maximum rotation speed of the spotlight, in degrees per second.
Spotlight Length <integer>
Length of the spotlight beam.
Spotlight Width <integer>
Width of the spotlight beam.
Color (R G B) <color255>
The color of the beam. Black makes the beam invisible, so no "Shadow Beams."
HDR color scale. <float>
float value to multiply sprite color by when running in HDR mode.

Targetname:

Name <string>
The targetname that other entities refer to this entity by.
Entity Scripts <scriptlist> (New with Left 4 Dead 2)
Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions.
Script think function <string> (New with Left 4 Dead 2)
Name of a function in this entity's script which will be called automatically every 100 milliseconds (ten times a second) for the duration of the script. It can be used to create timers or to simulate autonomous behavior. The return value (if present) will set the time until the next call.
Note:Try to avoid expensive operations in this function, as it may cause performance problems.

Parentname:

Parent (parentname) <targetname>
Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma.

RenderFields:

Render Mode (rendermode) <choices>
Set a non-standard rendering mode on this entity.
Render FX / Transparency (0 - 255) (renderamt) <integer>
Transparency amount, requires a Render Mode other than Normal. 0 is invisible, 255 is fully visible.
Render Color (R G B) (rendercolor) <color255>
Color tint.
Disable Receiving Shadows (disablereceiveshadows) <boolean>
Prevent the entity from receiving shadows on itself.

RenderFXChoices:

Render FX (renderfx) <choices>
Preset pattern of appearance effects.
To do: 18-21, 25

Angles:

Pitch Yaw Roll (Y Z X) <angle>
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.

DXLevelChoice:

Minimum DX Level (mindxlevel) <choices>
The entity will not exist if the engine is running outside the given range of DirectX Versions. Replaced by SystemLevelChoice from <Left 4 Dead> Left 4 Dead onwards.
Warning: If these are used, the object may break when the user switches their DirectX settings.
Maximum DX Level (maxdxlevel) <choices>

SystemLevelChoice:

Minimum CPU Level (mincpulevel) <choices> (New with Left 4 Dead)
A user with a CPU level lower than this will not see this object rendered in-game. CPU levels are determined by the Effect detail setting.
Maximum CPU Level (maxcpulevel) <choices> (New with Left 4 Dead)
  • 0: Default
  • 1: Low
  • 2: Medium
  • 3: High
Minimum GPU Level (mingpulevel) <choices> (New with Left 4 Dead)
A user with a GPU level lower than this will not see this object rendered in-game. GPU levels are determined by the Shader detail setting.
Maximum GPU Level (maxgpulevel) <choices> (New with Left 4 Dead)
  • 0: Default
  • 1: Very low
  • 2: Low
  • 3: Medium
  • 4: High

Flags

  • 1 : Start On
  • 2 : No Dynamic Light
  • 4 : Start rotation on
  • 8 : Reverse Direction
  • 16 : X Axis
  • 32 : Y Axis

Inputs

LightOn
Turn the spotlight on.
LightOff
Turn the spotlight off
Start
Start the rotator rotating.
Stop
Stop the rotator from rotating.
Reverse
Reverse the direction of rotation of the rotator.

Targetname:

Kill
Removes this entity and any entities parented to it from the world.
KillHierarchy
Functions the same as Kill, although this entity and any entities parented to it are killed on the same frame, being marginally faster than Kill.
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.
Use  !FGD
Same as a player invoking +use; may not do anything. Can also be invoked by creating an output that does not specify an input.
This input is not included in Valve's FGDs.
RunScriptFile  <script> (New with Left 4 Dead 2)
Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.
RunScriptCode  <string> (New with Left 4 Dead 2)
Execute a string of VScript source code in the scope of the entity receiving the input. String quotation may be needed when fired via console.
Bug: In <Left 4 Dead 2>, the code is executed in the script scope of the entity that fires the output, not the one receiving the input.
Warning: Never try to pass string parameters to a script function with this input. It will corrupt the VMF structure because of the nested quotation marks, which then must be removed manually with a text editor.
CallScriptFunction  <string> (New with Left 4 Dead 2) !FGD
Execute a VScript function in the scope of the receiving entity.
SetLocalOrigin  <coordinates> (New with Alien Swarm) !FGD
Send this entity to a spot in the map. If the entity is parented to something, it will be offset from the parent by this amount.
SetLocalAngles  <angles> (New with Alien Swarm) !FGD
Set this entity's angles.

Parentname:

SetParent  <string>
Move with this entity. See Entity Hierarchy (parenting).
SetParentAttachment  <string>
Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.
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 the the movement hierarchy, leaving it free to move independently.

RenderFields:

Alpha  <integer>
Sets the entity's transparency to a number from 0 (invisible) to 255 (fully visible). Requires the entity to have its Render Mode (rendermode) set to a number other than 0.
Color  <color255>
Sets an RGB color for the entity.

Outputs

OnLightOn
Fires when light turns on.
OnLightOff
Fires when light turns off.

Targetname:

OnUser1 to OnUser4
These Outputs each fire in response to the firing of the like-numbered FireUser1 to FireUser4 Input; see User Inputs and Outputs.
OnKilled  (Only in the Left 4 Dead series)
This Output fires when the entity is killed and removed from the game.
