{{l4d series point|info_director}}
It is the notorious AI Director, and must exist in every L4D and [[Left 4 Dead 2|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.

{{l4d2 add|[[logic_director_query]]}} 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 <code>forcesurvivorpositions</code> 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 <code>forcesurvivorpositions</code> 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 <code>ongamestart</code> 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.
