Todo:The deprecated template {{Base point}}, {{Point ent}} or {{Tf2 point}} (and similar) was used. Use {{Entity}} instead.

prop_laser_relay is a point entity available in Portal 2.

Entity description

A laser catcher that has target for lasers to strike. The entity will fire outputs when struck and unstruck.

Keyvalues

laser relay model <model path>

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.

Targetname:

Name (targetname) <string>

The targetname that other entities refer to this entity by.

Reflection:

Render in Fast Reflections (drawinfastreflection) <boolean> (in all games since )

If enabled, this entity will render in fast water reflections (i.e. when a water material specifies $reflectonlymarkedentities) and in the world impostor pass.

Inputs

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.

Base:

AddContext <string>

Adds to the entity's list of response contexts. Format is <key>:<value>.

AddOutput <string>

Assigns a new keyvalue/output on this entity. For keyvalues, some rely on extra necessary code to be ran and won't work if its simply just changed through this input. There is a strict format that must be followed:

Syntax: 

// Format of changing KeyValues: "AddOutput [key] [value]"
//// Raw text:
"OnUser1" "!self,AddOutput,targetname new_name"

// Format of adding an Output: "AddOutput {targetname}:{inputname}:{parameter}:{delay}:{max times to fire, -1 means infinite}"
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:SetParent:!activator:0.0:-1"
// Arguments can be left blank, but the empty blank should still be contained.
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:ClearParent::0.0:-1"

ClearContext

Removes all contexts from this entity's list.

ClearParent

Removes this entity from the the movement hierarchy, leaving it free to move independently.

FireUser1 to FireUser4

Fires the respectiveOnUseroutputs; see User Inputs and Outputs.

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 thanKillinput.

RemoveContext <string>

Remove a context from this entity's list. The name should match the key of an existing context.

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.

Use  !FGD

Same as a player invoking +use; no effect in most cases.

DispatchResponse <string> !FGD

Dispatches a response to the entity. See Response and Concept.

DispatchEffect <string> (removed since ) !FGD

Dispatches a special effect from the entity's origin; see also List of Client Effects. Replaced by the particle system since .

RunScriptFile <script> (in all games since ) (also in )

Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.

RunScriptCode <string> (in all games since ) (also in )

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 Hammer, using string arguments will corrupt the VMF file's structure, making the file unviewable for the next Hammer session.

Fix:Remove the string argument manually with a text editor.

Note: Backtick characters ` are replaced with quotation marks at runtime, allowing quotation marks to be used when normally not possible.

CallScriptFunction <string> (in all games since ) (also in ) !FGD

Calls a VScript function defined in the scope of the receiving entity.

TerminateScriptScope  (only in ) !FGD

Destroys the script scope of the receving entity.

SetLocalOrigin <coordinates> (in all games since ) !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> (in all games since ) !FGD

Set this entity's angles.

Reflection:

DisableDrawInFastReflection  (in all games since )

Turns off rendering of this entity in reflections when using $reflectonlymarkedentities in water material.

EnableDrawInFastReflection  (in all games since )

Turn on rendering of this entity in reflections when using $reflectonlymarkedentities in water material.

Outputs

OnPowered

Fired when a laser hits the target.

OnUnpowered

Fired when a laser has stopped hitting the target.

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 )

This output fires when the entity is killed and removed from the game.
