logic_choreographed_scene is a point entity available in all Source games. It manages a choreographed scene of one or more actors.

For an example on how this entity can be used, see the npc_gman_overwatch prefab.

Bug:In multiplayer, the actor must be within a player's PVS in order for lines to be heard. This does not apply in Portal 2   [todo tested in?]

AltNames: This entity is also tied to scripted_scene. There are lines in code searching for "logic_choreographed_scene".

Todo: document side effects of using scripted_scene as classname

Keyvalues

Name (targetname) <string>

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

Scene file (SceneFile) <scene>

The VCD scene file to use.

Target 1 (target1) to Target 8 (target8) <targetname>

Use these keyvalues to specify the resolution of Actor or Event Target names that are using a !Target# name in the VCD.

If an Actor is talking... (busyactor) <choices>

What to do if an actor this scene needs is already talking when this scene is told to start.

• 0 : Start immediately
• 1 : Wait for actor to finish
• 2 : Interrupt at next interrupt event
• 3 : Cancel at next interrupt event

On player death (onplayerdeath) <choices>

What should this entity do if the player dies

• 0 : Do Nothing
• 1 : Cancel Script and return to AI

Inputs

Start

Pause

Pauses playback of the scene file

Resume

Resumes playback of the scene if it has been paused

Cancel

CancelAtNextInterrupt

Cancels playback of the scene at the next interrupt event in the scene.

PitchShift <float>

Multiplies the pitch

InterjectResponse <string>

Finds an actor who can respond to the specified concept string while the scene continues playing.

Note:In order to use the interjection, the target actor needs to have a "Permit Responses" event (or multiple) added on the choreo timeline, and the playback needs to be within the span of those events.
The input parameter here is the name of the response concept, not the response itself.

Tip:The sole instance in which this feature is used in Half-Life 2 is in Kleiner's Lab.
See sdk_d1_trainstation_05.vmf provided in the Source SDK, and see the VCD such as scenes/k_lab/lab01.vcd for the Permit Responses usage.
