L4D2 Director Scripts

Usage

Director scripts typically contain a table named DirectorOptions, which contains variables that change up the decision making of the Director. They can be ran / stopped with the following inputs to the info_director entity:

BeginScript <string>: Run a Director script, and parse its DirectorOptions table once. If a Director script is already running and this input is called, the previous Director script automatically stops running.
EndScript: Ends the running script and resets the Director options to either the map's DirectorOption values, or the default settings.
ScriptedPanicEvent <string>: With the script name given it'll be ran as a Scripted Panic Event, which is like a mini finale, so the script should be structured as a finale script.

Note: Scripts used with ScriptedPanicEvent will not work if they are in a subdirectory under thevscriptsfolder, even though you can use subdirectories in other script contexts. If they don't reside under the vscripts folder, they will simply act as a 1 stage 1 second delay Panic Event.

There is too, a CDirector object for VScripts, which its extra functions can be paired for customizing your Director scripts.

General scripts and Onslaughts

Scripts launched with the BeginScript Director input run until a different script is launched, or the script is manually ended with the EndScript input. Unless new Director Options are set, the gameplay continues on as normally.

Onslaught events are created by manipulating the pacing and spawn limits of mobs and special infected.

c2m4_barns_onslaught.nut (with annotations):

Msg("Initiating Onslaught\n");

DirectorOptions <-
{
	// This turns off tanks and witches (when true).
	ProhibitBosses = false
	
	//LockTempo = true

	// Sets the time between mob spawns. Mobs can only spawn when the pacing is in the BUILD_UP state.
	MobSpawnMinTime = 1
	MobSpawnMaxTime = 1

	// How many zombies are in each mob.
	MobMinSize = 30
	MobMaxSize = 30
	MobMaxPending = 30

	// Modifies the length of the SUSTAIN_PEAK and RELAX states to shorten the time between mob spawns.
	SustainPeakMinTime = 5
	SustainPeakMaxTime = 10
	IntensityRelaxThreshold = 0.99
	RelaxMinInterval = 1
	RelaxMaxInterval = 5
	RelaxMaxFlowTravel = 50

	//Special infected options
	SpecialRespawnInterval = 1.0
        SmokerLimit = 2
        JockeyLimit = 0
        BoomerLimit = 0
        HunterLimit = 2
        ChargerLimit = 1

	// Valid spawn locations
	PreferredMobDirection = SPAWN_NO_PREFERENCE
	ZombieSpawnRange = 2000
}

Director.ResetMobTimer()		// Sets the mob spawn timer to 0.
Director.PlayMegaMobWarningSounds()	// Plays the incoming mob sound effect.

Finales and Scripted Panic Events

Finales and Scripted Panic Events consist of a number of different kind of stages set in DirectorOptions.

The Director script for the finale is always loaded from <map name>_finale.nut. Scripted panic events are initiated from the info_director ScriptedPanicEvent input.

Bug: While the trigger_finale entity has an option to specify a script, it is non-functional.

A stage can be one of 4 types (other values will break the finale and go right to ESCAPE):

PANIC - A panic event, the value is the number of waves of infected.
TANK - Spawn a tank(s), the value is the number of tanks to spawn.
DELAY - A delay, the value is the number of seconds to wait before proceeding to the next stage.
SCRIPTED (also called ONSLAUGHT) - The value should be the name of a VScript to call, or at least just any string "" (which just won't do anything and will be skipped). Any bad value here will crash you to the desktop. To do: Confirm the last part.

Your script however is responsible for sending an EndCustomScriptedStage input to the Director with a goal of your choice, like a certain trigger volume or a timer. For finales, trigger_finale input AdvanceFinaleState is an available alternative, but so is theMinimumStageTimeDirectorOptions key. Otherwise, the SCRIPTED stage will not end.

Bug: Sending an EndCustomScriptedStage input ends the Scripted Panic Event immediately.

Bug: After a Scripted Panic Events ends, the last stage of the event will repeat itself with the lowest valid value. So with PANIC and TANK stages, they will repeat once again with 1x spawn wave / spawn count, while for DELAY and SCRIPTED stages, nothing will happen.

An example custom finale script:

const ERROR = -1
const PANIC = 0
const TANK = 1
const DELAY = 2
const SCRIPTED = 3 

DirectorOptions <-
{
	//-----------------------------------------------------
	A_CustomFinale_StageCount = 4 // Number of stages. Used for calculating the Versus score.
	B_CustomFinale_StageCount = 4 // Number of stages for the alternate B finale type
	
	A_CustomFinale1 = PANIC
	A_CustomFinaleValue1 = 2	// Two panic waves.
	
	A_CustomFinale2 = DELAY
	A_CustomFinaleValue2 = 12 	// Delay for twelve seconds in addition to stage delay.
	
	A_CustomFinale3 = TANK
	A_CustomFinaleValue3 = 3 	// 3 tanks!
	
	A_CustomFinale4 = DELAY
	A_CustomFinaleValue4 = 6	// Wait some more... and its rescue for Finale Type A!
	
	B_CustomFinale1 = SCRIPTED
	B_CustomFinaleValue1 = "my_challenging_scripted_stage"	// Start of with running a custom scripted stage using a separate script.
	
	B_CustomFinale2 = DELAY
	B_CustomFinaleValue2 = 15	// Wait 15 seconds.
	
	B_CustomFinale3 = TANK
	B_CustomFinaleValue3 = 1 	// One more tank.

	B_CustomFinale4 = DELAY
	B_CustomFinaleValue4 = 10	// Wait ten seconds ... rescue for Finale Type B!

	//-----------------------------------------------------

	CommonLimit = 10
	SpecialRespawnInterval = 25
}

function OnBeginCustomFinaleStage( num, type ) // This function is run at the beginning of every stage.
{
	printl( "Beginning custom finale stage #" + num + " of type: " + type )
	if( num != 1 && DirectorOptions.CommonLimit < 30 )
		DirectorOptions.CommonLimit = num * 5 // Increase commons by 5 linearly with stages.
}

To do: Add info from [1]

Callbacks

float GetCustomScriptedStageProgress(float defvalue)

Will be called during FINALE_CUSTOM_SCRIPTED stages. The function should return a value from 0-1 to indicate the completion percentage of the stage. The default time-based completion percentage is passed in as a parameter.

void OnBeginCustomFinaleStage(int num, int type)

If defined, will be called on every stage change with the number, and type, this is how you would change director options between stages (spawn directions, etc). num refers to the finale stage number passed by the director and type is the stage type (PANIC, TANK, etc.).

Bug: The CEntities object will not work properly in this callback, always returning the default value null every tick until Squirrel terminates the script.

DirectorOptions

TheDirectorOptionstable is used for overriding various Director variables that govern among other things: infected spawning rough distance, finale stages, and others.

In mode and map scripts, use SessionOptions and MutationOptions/MapOptions! SessionOptions for influencing the director, while the MutationOptions/MapOptions tables for setting default values. This is because the normal DirectorOptions table can conflict with other scripts, especially on a finale event, as custom finales are often and require DirectorOptions.

Note: 'Mode scripts' term refer to scripts ran when a specific gamemode is active, likeshootzones.nutorc3m1_plankcountry_holdout.nut. 'Map scripts' on the other hand, are ran anytime during a map, dependent of map logic. Examples for this include:c9m1_alleys_minifinale.nutandc11m4_reserved_wanderers.nut.

Though, while customizing the Director's behaviour, you might come across these issues:

The Fields interact a lot!
Say you have a custom mutation mod, and you use aDirectorOptionstable to influence the Director. It reducesCommonLimit for lesser Commons, but also reduces bothMobSpawnTimeMinandMobSpawnTimeMax to make them respawn faster. However, when playtesting your mod on Dead Center, everything seems to revert to default after you complete the Gauntlet fetch quest, featuring weapon_cola_bottles. While not a great example scenario, this is to show something that can happen if you're not careful: Things working not as expected, as DirectorOptions have been set in ways that conflict, causing unexpected behaviors.

When you see odd behavior like this, think about what other variables and objects might be interfering with your plans. Going back to the earlier example, the cause of this could be other scripts using aDirectorOptionstable, so if you remember, you could try aMutationOptionstable and see if it works. But if it doesn't, its okay, because if you inspect the keys documentation below, you'll find out the keycm_CommonLimitalso exists, and could solve your other problems. Viewing the list of usableDirectorOptionskeys can be very vital when debugging issues like these, sometimes you find something that just does what exactly you want.

Don't forget to use the proper assignment operator!
With a new DirectorOptions table, you should use the<-operator. <- is required over using thelocaltag and the= operator, as variables created with<-become globals, allowing the C++ side of the game to use DirectorOptions.

Note: The default values are for reference of the values set elsewhere in-game (if it has one), and do NOT mean that the DirectorOption key is set by default. Blank values for a key also imply something simply has no default value.

`GasCansOnBacks`	bool	false	Puts the Hard Rain diesel cans on the survivors backs.
`GetSpecialSlotCountdownTime`	float
`IgnoreNavThreatAreas`	bool	false	Likely prevents bosses from spawning along the nav. To do: confirm category/working
`InfectedFlags`	int	0	Applies flags to newly spawned infected. Valid flags are: `INFECTED_FLAG_CANT_SEE_SURVIVORS, INFECTED_FLAG_CANT_HEAR_SURVIVORS, INFECTED_FLAG_CANT_FEEL_SURVIVORS`
`IntensityRelaxAllowWanderersThreshold`	float		If the maximum intensity of the survivors is below this threshold, wandering commons can spawn.
`IntensityRelaxThreshold`	float		All survivors must be below this intensity before a Peak is allowed to switch to Relax (in addition to the normal peak timer)
`JournalString`	string	-none-	To do: Used in holdout, seems to build some kind of table. Is this for the Director Journal related I/O inputs?
`LockTempo`	bool	false	Locks the horde spawning to only be at the COMBAT phase. Note: The horde spawning pacing consists of: BUILD_UP -> spawn horde -> SUSTAIN_PEAK -> RELAX -> BUILD_UP again. Setting`LockTempo = true`removes the "SUSTAIN_PEAK -> RELAX -> BUILD_UP" bit making your hordes spawn constantly without a delay.
`MobRechargeRate`	float		Guessing it's the speed at which a mob regenerates (i.e. next mob).
`MobSpawnMaxTime`	float	180.0-240.0	Maximum time in seconds between mob spawns. Default value depends on difficulty.
`MobSpawnMinTime`	float	90.0-120.0	Minimum time in seconds between mob spawns. Default value depends on difficulty.

Note: `SPAWN_LARGE_VOLUME`is what makes infected be a considerable distance away, like on Dead Center finale. However.. for the technical people thinking its too vague, `SPAWN_LARGE_VOLUME`makes infected ignore variables that constraint their spawning behavior, like ZombieSpawnRange. This massive freedom given to the infected, unintentionally but also desirably, makes mobs split up to more than one spots per spawn, and also usually has them spawning quite a distance away when they can.
`PreferredMobPosition`	Vector	-none-	To do: confirm category/working; used in dash
`PreferredMobPositionRange`	float	-none-	To do: confirm category/working; used in dash

`ZombieDiscardRange`	int	2500	Any CI beyond this point will be deleted, while any AI-controlled SI will suicide.
`ZombieDontClear`	bool	false	Do not mark nav areas as cleared.
`ZombieSpawnInFog`	bool	false	Allows zombies to spawn in in line-of-sight of survivors in fogged areas.
`ZombieSpawnRange`	float	1500.0	Maximum distance from the survivors that the infected can spawn.
`ZombieTankHealth`	float	2000.0 in Easy; +2000.0 for every higher difficulty	Sets the amount of health a tank spawns with. Default value is difficulty dependant.

function void g_ModeScript::GetNextStage()

Called by the director when it wants a new stage. It can be forced with Director.ForceNextStage()

Finale Specific/Related

A normal finale consists of X number of stages. Some variables in DirectorOptions can only be used during finales. Multiple staged events can be defined in the same script, with the Options starting with A_, B_, C_ etc.

Name	Type	Default value	Description
`[A-Z]_CustomFinale_StageCount`	int	-none-	Number of stages. Needs to be set for Versus scoring to function properly.
`[A-Z]_CustomFinaleX`	int	-none-	Stage type (enumerated PANIC, SCRIPTED (AKA ONSLAUGHT), DELAY, TANK), where X is the corresponding stage number. Usable in scripted panic events.
`[A-Z]_CustomFinaleValueX`	any	-none-	Value depends on the stage type above. Usable in scripted panic events.
`[A-Z]_CustomFinaleMusicX`	string	-none-	Soundscript entry to play. For instance, `A_CustomFinaleMusic1 = "C2M5.BadManTank2"` will play a Dark Carnival - Concert finale song. Does not work in Scripted Panic Events. Note: Dark Carnival - Concert finale does not use this method! It instead uses map logic and ambient_music. However its finale script has`A_CustomFinaleMusic4= ""`, suggesting that it may be disabling the default Tank music.
`EnforceFinaleNavSpawnRules`	bool	true	Possibly used to enforce the finale spawning behavior without running a finale. To do: confirm category/working
`HordeEscapeCommonLimit`	int	-1	Number of commons allowed in the escape stage.
`EscapeSpawnTanks`	bool	true	Whether to spawn tanks in the escape sequence. To do: possibly EMS stage related
`MinimumStageTime`	float	1.0	The minimum amount of time a SCRIPTED stage is allowed to run before ending. Unavailable for Scripted Panic Events.

Gauntlet Specific/Related

These options are specific to Gauntlet finales. Most of these can be found in director_gauntlet.nut

Name	Type	Default value	Description
`CustomTankKiteDistance`	float	3000.0	Controls when the Gauntlet's Tank wave should start if a survivor advanced this far, in flow distance.

Movement Bonus related options: Movement Bonus are an unique RELAX pacing method present only in Gauntlet finales. Everytime the Movement Timer finishes its timing, Movement Bonus is incremented by its set value. However if a new mob spawns, the Director initiates an extra variable afterwards: Current Bonus. Current Bonus is a timer that lasts as long as the current Movement Bonus, which when still ticking down, disallows the Director from spawning any new infecteds (except Tanks).

To familiarize with Movement Bonus better, usedirector_debug 1in-game to see the values.

Name	Type	Default value	Description
`GauntletMovementThreshold`	float	500.0	When survivors advance this many amount of flow distance, from the last reset point or the start point, Movement Bonus, Movement Timer and Current Bonus is reset to defaults.
`GauntletMovementTimerLength`	float	5.0	The interval between each Movement Bonus increase, in seconds.
`GauntletMovementBonus`	float	2.0	The initial value, and the amount the movement Bonus increases everytime the timer stops, in seconds.

Name	Type	Default value	Description
`TankHitDamageModifierVersus`	float	1.0	Damage dealt by Tanks is multiplied by this number in Versus modes.
`ZombieGhostDelayMax`	float	30.0	Maximum time in seconds until allowing player infected to respawn.
`ZombieGhostDelayMin`	float	20.0	Minimum time in seconds until allowing player infected to respawn.

Dump of Enumerations fromDirectorScript table. If you have a script that intends to access these, but won't be ran with the info_director's inputs, access the enums like this manner to avoid errors:DirectorScript.ALLOW_BASH_ALL.

Some enums here are bitmasked (these:1 << 2), so they can be combined with other ones. Any hook / callback functions are stylized as italics.
