vgui_movie_display is a point entity available in all Source games since <Alien Swarm> Alien Swarm. This entity is used to display videos in the world. Portal 2 uses the Bink format for videos, while [Portal 2: Community Edition] Portal 2: Community Edition uses the WebM format.

A movie screen is typically a brush face textured with elevator/elevator_screen or one of its variants. Make sure you click "Fit" in the Texture Application Tool.

Note.png Note: If the video has sound, it will be heard at full volume everywhere in the map.
Note.png Note: [Portal 2: Community Edition] uses webm instead of bink video.
Bug.png Bug: The video restarts when pausing and unpausing the game.
Bug.png Bug: The movie display does not fade into fog, and rarely is visible through walls.
Bug.png Bug: Non-functional in <Alien Swarm><Counter-Strike: Global Offensive>.

Stretching movies across multiple screens

The master/slave keyvalues and U/V inputs on the entity can be used to stretch a movie across multiple displays. The usual setup for this involves one vgui_movie_display with "_master" at the end of its targetname, which then controls a group of slave vgui_movie_displays that have "Forced Slave" enabled and the same "Group Name" as the master entity.

Place a slave vgui_movie_display for each screen at the lower-left corner of the face. Change the width and height to match each panel. The U/V inputs can be used to set which part of the image is displayed on each screen.

To start the movie, fire an "Enable" input at all vgui_movie_display entities; wildcards are useful for this.

Elevator videos

Valve includes a system for selecting elevator videos in custom maps. The arrival_departure_transition_ents instance includes a pair of instance parameters which can be used to set the arrival and departure videos respectively. The video_splitter.nut VScript will automatically handle setting the correct U/Vs.

To do: No longer works since the Perpetual Testing Initiative update. Are there any good community-made alternatives?

Property Name Value
Fix up Name
VMF Filename instances/transitions/arrival_departure_transition_ents.vmf
Replace $arrival_video media/faithplate.bik
Replace $departure_video media/animalking.bik

The video_splitter script also contains a list of all singleplayer campaign maps and which videos each map should play. For mods, it is recommended to add the mod's maps to this list. Single maps should continue to use the method above.


Display Text <string>
Unknown use, appears non-functional.
Movie Filename <string>
Path to the video file, located in media/. Portal 2 uses Bink (.bik) videos, while P2CE uses WebM (.webm) videos. See List of Portal 2 Movies for a list of default videos in Portal 2 (P2CE also includes WebM versions of these).
Group Name <string>
What group of vgui_movie_display entities it belongs to.
Loop Movie <boolean>

Classname (classname) <string>
The classname defines the type of entity. Classnames can be changed using AddOutput, which will influence how the engine deals with the entity in certain circumstances.
Name (targetname) <string>
The name that other entities refer to this entity by.
Global Entity Name (globalname) <string>
Name by which this entity is linked to another entity in a different map. When the player transitions to a new map, entities in the new map with globalnames matching entities in the previous map will have the previous map's state copied over their state.
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. Every entity can be parented, even point entities. Entities which are parented will be forced to transition to the next map, such as from a trigger_transition. Some entities which aren't intended to be parented may not function correctly. phys_constraint can be used as a workaround to parenting.
Origin (X Y Z) (origin) <coordinates>
The position of this entity's center in the world. Rotating entities typically rotate around their origin.
Pitch Yaw Roll (X Y Z) (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.
Note.png Note: This works on brush entities, although Hammer doesn't show the new angles.
Flags (spawnflags) <integer>
Toggles features of an entity, its specific number is determined by the combination of flags added.
Response Contexts (ResponseContext) <string>
Pre-defined response system contexts for this entity. Format is key:value,key:value,.... Contexts may be filtered.
Effects (effects) <integer> !FGD
Combination of effect flags to use.
Hammer ID (hammerid) <integer> !FGD
The entity's Hammer ID. Mainly used by plugins and debugging commands, such as ent_keyvalue. Entities spawned at run-time are not assigned any Hammer ID.
Entity Scripts (vscripts) <scriptlist> (in all games since <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 (thinkfunction) <string> (in all games since <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. Try to avoid expensive operations in this function, as it may cause performance problems.
Lag Compensation (LagCompensate) <boolean> (in all games since <Left 4 Dead 2>) !FGD
Set to Yes to lag compensate this entity. Should be used very sparingly!
Disable for Xbox 360 (disableX360) <boolean> (in all games since <Left 4 Dead 2>) !FGD
If this entity should automatically be given the 'Disable' input on the Xbox 360 version of Source.
Is Automatic-Aim Target (is_autoaim_target) <boolean> (in all games since <Counter-Strike: Global Offensive>) !FGD
If set to 1, this entity will slow down aiming movement for consoles and joystick controllers when the entity is under the crosshairs.

Format: <key> <value>
Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>
Removes this entity and any entities parented to it from the world.
Functions the same as Kill, although this entity and any entities parented to it are killed on the same frame, being marginally faster thanKillinput.
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.
Removes this entity from the the movement hierarchy, leaving it free to move independently.
FireUser1 to FireUser4
Fire the OnUser outputs; see User Inputs and Outputs.
AddContext <string>
Adds to the entity's list of response contexts. Format is <key>:<value>.

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> (in all games since <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> (in all games since <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.png 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.png 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> (in all games since <Left 4 Dead 2>) !FGD
Execute a VScript function in the scope of the receiving entity.
SetLocalOrigin <coordinates> (in all games since <Alien Swarm>) !FGD
