Left 4 Dead 2/Scripting/Director Scripts

Left 4 Dead 2 Director scripts are vscripts that are primarily used to influence the behavior of the AI Director. They are extensively used for custom finales and gauntlet events.

Usage

Director scripts are executed with inputs to the info_director entity. A DirectorOptions table is used to give new temporary values for the variables the director uses for decision making. Additional commands can be accessed through the Director object. Only one Director script can be running at a time.

Inputs

BeginScript <script name>

Executes a generic Director script, for example for onslaught events or changing spawning behavior.

EndScript

Ends the running script and resets the Director options to the map specific values.

BeginScriptedPanicEvent <script name>

Begins a Scripted Panic event.

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 launched from the info_director ScriptedPanicEvent input.

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 "" (which will do nothing), any bad value here will crash you to the desktop. Your script is responsible for sending an EndCustomScriptedStage input to the director (a goal of your choice, like a certain trigger volume, timer, random value, etc.). trigger_finale input AdvanceFinaleState may also work. Otherwise, the onslaught will not end.

An example custom finale script:

ERROR <- -1
PANIC <- 0
TANK <- 1
DELAY <- 2
SCRIPTED <- 3 

DirectorOptions <-
{
	//-----------------------------------------------------
	 A_CustomFinale_StageCount = 8 // Number of stages. Used for calculating the Versus score.
	 
	 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 = 12 // Wait some more.
	 
	 A_CustomFinale5 = SCRIPTED
	 A_CustomFinaleValue5 = "my_scripted_stage.nut" // Run a custom scripted stage using a separate script.
	 
	 A_CustomFinale6 = DELAY
	 A_CustomFinaleValue6 = 15 // Wait 15 seconds.
	 
	 A_CustomFinale7 = TANK
	 A_CustomFinaleValue7 = 1  // One more tank.

	 A_CustomFinale8 = DELAY
	 A_CustomFinaleValue8 = 10 // Wait ten seconds ... rescue!


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

	 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 );
      MapScript.DirectorOptions.CommonLimit <- num * 10 // Increase commons by 10 linearly with stages.
}

DirectorOptions

The DirectorOptions table is used for overriding various Director variables that govern among other things, infected spawning, finale stages and more.

Note:In mode and map scripts, use the SessionOptions table to influence the director instead, or the MutationOptions/MapOptions tables for initial values. The DirectorOptions table can get overwritten or cleared by map events, and writing a new DirectorOptions on a finale will erase the finale script.

Information about some of the Director Options found in the Steam Forums.

Warning: The Fields interact a lot

For instance, SpecialRespawnInterval is "how long after a special of type X dies can we spawn another one." Setting this fairly high (the default) makes a lot of sense in a flow based movement. Whereas if you are building a mutation where you stay in a single place, or where you want a ton of boomers, keeping it set high means that whenever you kill a boomer there will be a long wait until the Director is allowed to spawn a new one. So you'd want to set this value very low if your mod wants to do that.

This brings up the main point: often things don't work as expected, because the DirectorOptions have been set in ways that conflict, causing unexpected behaviors. You can set 3 variables to get what you want, but a 4th may default to something that thwarts you. So it is worth learning about all the options, because it is very easy to over-constrain the Director. When you see odd behavior, think about what other variables and settings might be interfering with your plans.

Warning: NEVER use the = operator when trying to influence the director. Use <-. The difference is semantics. If you use =, it will throw an error if the table slot isn't defined (like if a previous script didn't define it). <-, on the other hand, will create the variable if it does not exist. Some of these samples are only portions of a full script, so make sure that the variables are created beforehand.

Note:The default values are for reference of the values set elsewere in-game, and does NOT mean that the DirectorOption is set by default.

• function Update()

If you define an Update() function in your vscript, it will run repeatedly much like a Think() function, but ONLY a finale via trigger_finale is triggered, if you have multiple scripts that are running that define it, they all will be called. The use of Update() is also found in the Bleed Out mutation (mutation3.nut), but needs further testing to see see if it behaves the same way like during a finale.

• 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_CustomFinale_StageCount	int		Number of stages. Needs to be set for Versus scoring to function properly.
A_CustomFinaleX	int		Stage type (enumerated PANIC, SCRIPTED (AKA ONSLAUGHT), DELAY, TANK), where X is the stage number. Also used in scripted panic events.
A_CustomFinaleValueX	*		Value depends on the stage type above. Also used in scripted panic events. Please see the example above.
A_CustomFinaleMusicX	string		Soundscript entry to play. For instance, A_CustomFinaleMusic1 = "C2M5.BadManTank2". Note that c2m5_concert_finale.nut does not use this method and instead opted to use entities within the map instead. In the c2m5 script A_CustomFinaleMusic4 = "", suggesting that no song is actually played automatically via script.
EnforceFinaleNavSpawnRules	bool		Possibly used to enforce the finale spawning behavior without running a finale. Todo: confirm category/working

• function OnBeginCustomFinaleStage( num, 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.).

Movement Bonus related options

The Movement Bonus successively increases the delay between hordes when the survivors are not making progress toward the Gauntlet goal. The Current Bonus value ticks down every second, allows a horde to spawn when it reaches 0. When a horde spawns the Current Bonus is reset to the Movement Bonus value. The Movement Bonus increases at set intervals, and is reset when the survivors cross the Movement Threshold, which is then incremented. Use director_debug 1 to see the values.
