info_directoris 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 can output the director's anger level, allowing level designers to adjust conditions according to how well the players are doing.
- Using the changelevel console command to restart the map will cause the director to ignore the
- 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
forcesurvivorpositionsunless 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
ongamestartinput. 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.
- Entity Scripts
- 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
- 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 (X Y Z)
- The position of this entity's center in the world. Rotating entities typically rotate around their origin.
- Fired when a major event happens that the director should know about.
- 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.
- Make each survivor stand at an info_survivor_position.
- Note:Also hides HUD, except Survival and Scavenge specific HUD overlays.
- Allow survivors to move freely again.
- Note:Also enables HUD again.
- 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)
- Fire when the intro starts. Players are immune to damage while this is active. No mobs or SI will spawn.
- 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.
- Can be used to enable the tank frustration meter.
- Can be used to disable the tank frustration meter.
- Removes this entity from the world.
- Removes this entity and its children from the world. Note:Entities already remove orphaned children upon being removed, but this input removes all children on the same frame, being marginally faster than
- Adds a keyvalue/output to this entity. It can be potentially very dangerous, use with care.
<output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>
- Fire the
OnUseroutputs; see User Inputs and Outputs.
- Same as a player invoking +use; may not do anything depending on the entity. Can also be invoked by firing an output that does not specify an input.
- Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.
- 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 , 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.
- Execute a VScript function in the scope of the receiving entity.
- 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.
- Set this entity's angles.
The following are additional inputs only available in L4D2.
- Begin/End a Director VScript.
- Run a Scripted Panic Event, a staged event similar to a finale.
- Trigger a panic event, no matter what else is going on.
- End a scripted type finale stage.
- Increment a team's score. (2=survivors, 3=infected)
- Create a new journal.
- Add a task to the I/O Journal.
- Execute all tasks in the specified journal
- To do: seems to teleport survivors to the positions they spawned from.
- Fired when a map loads, all players join and gameplay begins.
- Fired when a panic event is finished.
- These outputs each fire in response to the firing of the like-numbered
FireUser4Input; see User Inputs and Outputs.
- This output fires when the entity is killed and removed from the game.
The following are additional outputs only available in L4D2. They focus on the new scavenge game mode and vscripts.
- Fired when each stage of a custom panic event or custom finale finishes. Relies on vscripts.
- Fired when a team places a scavenge item in the scavenge goal.
- Fired when a scavenge round starts.
- Timer has run out and game went into overtime.
- Time was added to the clock, ending overtime.
- Time has run out, game did not enter overtime.
- Intensity level has changed. 1 = highest intensity, decreases as number gets larger.
- Generic user defined event fired from a squirrel script (
