<Left 4 Dead><Left 4 Dead 2> info_director is a point entity available in the Left 4 Dead series. It is the notorious AI Director, and must exist in every L4D and L4D2 map for normal gameplay.

The director is almost entirely automated and only exists at design-time for the few situations in which other designer-placed entities need to communicate with it, such as for forcing survivors to their respective info_survivor_position at the start of a campaign for camera intro sequences.

logic_director_query (New with Left 4 Dead 2) can output the director's anger level, allowing level designers to adjust conditions according to how well the players are doing.

Caveats

Using the changelevel console command to restart the map will cause the director to ignore the forcesurvivorpositions input.
If you are restarting the map after a fresh compile using changelevel and you need to test out your intro sequence, use the kill console command afterwards to have the mission fail, this will cause the map to restart in a way that allows the info_director to use forcesurvivorpositions input, which will also allow your cameras to function.
logic_auto cannot trigger forcesurvivorpositions unless the map was freshly loaded from the game menu as a campaign, or is restarting after mission failure.
To get around this, have the director call forcesurvivorpositions and releasesurvivorpositions on itself using the ongamestart input. When your campaign is ready for release, you can safely change it back to using a logic_auto before final compilation if you wish, since players will be loading your campaign from the game menu.

Keyvalues

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.

Origin:

Origin (X Y Z) <origin>
The position of this entity's center in the world. Rotating entities typically rotate around their origin.

Inputs

<Left 4 Dead> Original inputs

PanicEvent
Fired when a major event happens that the director should know about.
PanicEventControlled <int>
Like Panic Event, but allows for some control of intensity, via the number of waves. Standard values are 1 for earlier maps, 2 for later maps.
Note:PanicEventControlled only works in L4D1. In L4D2, a series of panic event (and much more!) are triggered by running director vscripts.
ForceSurvivorPositions
Make each survivor stand at an info_survivor_position.
ReleaseSurvivorPositions
Allow survivors to move freely again.
FireConceptToAny <string>
Fire a speech concept to any survivor that is capable of speaking it. Allows survivor dialogue to be triggered by map entities (e.g. No Mercy's elevator with parameter hospital04_path4)
StartIntro
Fire when the intro starts. Players are immune to damage while this is active. No mobs or SI will spawn.
FinishIntro
Fire when the intro ends. Players will now take damage. Mobs and SI can spawn given that the player is no longer standing in a nav square marked as PLAYER_START and/or CHECKPOINT.
EnableTankFrustration
Can be used to enable the tank frustration meter.
DisableTankFrustration
Can be used to disable the tank frustration meter.

Targetname:

Kill
Removes this entity from the world.
KillHierarchy
Removes this entity and all its children from the world.
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.
Note:This input is missing from some games FGD files.
SetLocalOrigin  <origin> (New with Alien Swarm) !FGD
Set this entity's origin in the map.
Note:This input is missing from some games FGD files.
SetLocalAngles  <angles> (New with Alien Swarm) !FGD
Set this entity's angles in the map.
Note:This input is missing from some games FGD files.
