prop_mirror

prop_mirror is a point entity available in  Portal 2.

Entity description

It creates a square portal that mimics a mirror and which cannot be travelled through.

Note: The model won't be displayed if it doesn't have a MirrorSurface bodygroup.

Note: Any Model can be specified if you simply want the mirror funtionality; the model will not show and you will be left with a very simple mirror projection.

Bug:This entity does not work properly. Objects pop in and out of view, and sometimes the whole portal goes white.

Workaround: Place a brush flush to the room dimensions and tie it to a func_viscluster

Keyvalues

Width <float>

The width of the mirror when there's no model

Height <float>

The height of the mirror when there's no model

Physics <boolean>

Move physically

Studiomodel:

World Model (model) <string>

The model this entity should appear as. 128-character limit.

Skin (skin) <integer>

Some models have multiple skins. This value selects from the index, starting with 0.

Tip: Hammer's model browser automatically updates this value if you use it to view different skins.

Shadow:

Disable Shadows (disableshadows) <boolean>

Prevents the entity from creating cheap render-to-texture shadows, or lightmap shadows if the entity is a prop_static. Does not affect shadow mapping.

Disable ShadowDepth (disableshadowdepth) <boolean> (in all games since )

Used to disable rendering into shadow depth (for projected textures) for this entity.

Projected Texture Cache (shadowdepthnocache) <choices> (in all games since )

Used to hint projected texture system whether it is sufficient to cache shadow volume of this entity or to force render it every frame instead.

• 0 : Default
• 1 : No cache - render every frame
• 2 : Cache it - render only once

Disable flashlight (disableflashlight) <boolean> (in all games since )

Used to disable projected texture lighting and shadows on this entity.

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.

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.

Angles:

Pitch Yaw Roll (Y Z X) (angles) <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.

Targetname:

Name (targetname) <string>

The targetname that other entities refer to this entity by.

Inputs

Studiomodel:

Skin <integer>

Changes the model's skin to the specified number.

SetBodyGroup <integer>

Set the model's body group.

AlternativeSorting <boolean>

Uses an alternative method for telling which objects are in front of others. Use if this object draws incorrectly when seen through transparent things.

SetModelScale <string> (only in )

Sets the model scale. Takes two values separated by a space. The first is the target model scale. The second value is the number of seconds the change in scale will be spread over. If there is no second value, the model will scale instantly.

Warning:Negative or extremely high values can cause crashes!

Shadow:

DisableShadow

Turn dynamic shadows off for this entity. Identical to applying  EF_NOSHADOW.

EnableShadow

Turn dynamic shadows on for this entity.

DisableReceivingFlashlight  (in all games since )

This object will not receive light or shadows from projected textures.

EnableReceivingFlashlight  (in all games since )

This object may receive light or shadows from projected textures.

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.

ToggleDraw:

DisableDraw  (in all games since )

Add the EF_NODRAW flag to this entity. Some entities manage this on their own so be aware you can override that value.

EnableDraw  (in all games since )

Remove the EF_NODRAW flag from this entity. Some entities manage this on their own so be aware you can override that value.

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.

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.

Outputs

Studiomodel:

OnIgnite

Fired when this object catches fire.

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.
