Left 4 Dead 2/Scripting/Response System

This is a draft page. It is a work in progress open to editing by anyone.
Remember to check for any notes left by the tagger at this article's talk page.

This article or section needs to be cleaned up to conform to a higher standard of quality.

The response system used by Left 4 Dead 2 can be extended through VScript by creating custom decision rules. These rules allow scripts to evaluate criteria and select responses dynamically based on game state, similar to the built-in response rules used by the engine.

VScript response rules use the same general concept as the traditional response rule system, but instead of being defined through KeyValues files, rules are created using Squirrel tables.

A response rule consists of three main parts:

• name - An arbitrary rule name, mainly used for debugging.
• criteria - Conditions that determine whether a rule matches.
• responses - Actions performed when a rule is selected.

Response system structure

A response rule is a Squirrel table containing a name, criteria, and responses:

{
	name = "ExampleRule",

	criteria =
	[
		[ "concept", "TLK_REMARK" ],
		[ "who", "Coach" ],
		[ "subject", "ExampleSubject" ],
		[ "distance", 0, 500 ]
	],

	responses =
	[
		{
			scenename = "scenes/Coach/MoveOn01.vcd"
		}
	]
}

Multiple rules can be stored in an array:

[
	{
		name = "Rule1",
		criteria = [],
		responses = []
	},

	{
		name = "Rule2",
		criteria = [],
		responses = []
	}
]

Criteria

Criteria are used to determine if a rule is valid. Every criterion in a rule must match before the response can be selected.

Criteria can be either static comparisons or functions.

Static criteria

Static criteria compare a fact from the response query against a value.

A two-value criterion checks if a fact equals a value:

[ "concept", "TLK_HELP_ME" ]

This matches when the query contains:

concept = "TLK_HELP_ME"

A three-value criterion checks whether a number is within a range:

[ "distance", 0, 500 ]

This matches values between 0 and 500.

A missing value can be used as an unlimited range:

[ "distance", 500, null ]

Matches values greater than or equal to 500.

Function criteria

For information about what the query contains, see Query facts ↓

Criteria can also be functions that return true or false.

Important: When accessing functions or variables defined in the global response rule table, you must prefix them with g_rr..

Example:

function IsNotInCombat(query) // query param is IMPORTANT!!! DO NOT REMOVE!!!
{
	return query.incombat == 0;
}

// In the rules
criteria =
[
	[ IsNotInCombat ]
]

Example 2:

function SomeFunction() {
	//...
}

function SomeFunctionABC(query) {
	//...
}

MyGlobalVariable <- "ABC";

function IsNotInCombat(query) // query param is IMPORTANT!!! DO NOT REMOVE!!!
{
	g_rr.SomeFunction();
	
	g_rr.SomeFunctionABC(query);
	
	print(g_rr.MyGlobalVariable);

	return query.incombat == 0;
}

// In the rules
criteria =
[
	[ IsNotInCombat ]
]

Functions allow rules to perform custom checks that cannot be represented by simple comparisons.

Another example is using the param query to see if a survior is alive

function IsGamblerAlive(query) // query param is IMPORTANT!!! DO NOT REMOVE!!!
{
	return query.isgambleralive == 1;
}

criteria =
[
	[ IsGamblerAlive ]
]

Common criteria

concept

The concept represents the type of response being requested.

Examples:

[ "concept", "TLK_HELLO" ]
[ "concept", "TLK_HELP_ME" ]
[ "concept", "TLK_RELOAD" ]

who

who is not an entity lookup. It is a response query fact containing the speaker identifier supplied by the caller.

Built-in survivor responses commonly use internal survivor names:

• Coach
• Gambler (Nick)
• Mechanic (Ellis)
• Producer (Rochelle)
• Biker (Francis)
• Manager (Louis)
• NamVet (Bill)
• TeenGirl (Zoey)

However, custom scripts may provide any string value.

Example:

[ "who", "Virgil" ]

subject

The subject usually refers to the entity the response is directed toward.

Example:

[ "subject", "PlayerRemarkC1M1ThroughThisDoorCoach" ]

Responses

Responses define what happens when a rule matches.

A response can execute a scene, sound, or script function.

Scene responses

A response containing scenename plays a VCD scene:

responses =
[
	{ scenename = "scenes/Coach/MoveOn01.vcd" }
]

Script responses

A response can execute a VScript function:

function ExampleResponse(speaker, query)
{
	printl("Response executed")
}

responses =
[
	{ func = ExampleResponse }
]

The function receives:

• speaker - the entity performing the response.
• query - the response query table.

Response parameters

Responses can contain additional parameters controlling behavior.

Example:

{
	scenename = "scenes/Coach/MoveOn01.vcd",
	delay = 2,
	odds = 50
}

Common parameters:

Parameter	Description
nodelay	Removes the additional speaking delay.
defaultdelay	Adds the default response delay.
odds	Chance that the response is selected.
speakonce	Prevents the response from being used more than once.
weight	Changes selection priority between responses.
respeakdelay	Prevents the same response from playing again for a period of time.
applycontext
applycontexttoworld

Group parameters

Response groups control how responses are selected and repeated.

group_params = RGroupParams(
{
	permitrepeats = false,
	sequential = true,
	norepeat = false
})

Ususally it can just be group_params = RGroupParams().

Available options:

• permitrepeats - Allows responses to repeat before all responses have been used.
• sequential - Selects responses in order instead of randomly.
• norepeat - Disables the response group after all responses have been used.
• matchonce - Disables the rule after it matches once.

Criteria examples

criteria = [
	[ "concept", "onSeeEnemy" ], // arrays of two entries are considered to be fact = value
	[ "speaker", "coach" ],
	[ "numAllies", 1, 4 ],	// arrays of three entries are considered to be fact >= x && fact <= y
	[ "enemyType", "smoker" ],
	[ @(query) (query.GameTime) < 30 ] // arrays of one entry are expected to be functions (In this entry, its an anonymous function)
],

Important: g_rr is needed in the reponse rules when declaring criteria rules as a variable.

// if you want to share a criterion between many rules, you can declare it as its own variable like this:
CriterionIsNotCoughing <- [ "Coughing", 0 ]
CriterionIsc6m3_port  <- [ "map", "c6m3_port" ]  //use for the moveon example below to scope the rule change
CriterionIsAwardProtector  <- [ "awardname","Protector" ]

// and then include it into the criteria lists as per the examples below. The "g_rr." part
// is a bit of temporary cruft that will go away once we resolve some questions about scope resolution
// in map .nut files.

criteria = [
		[ "concept", "PlayerMoveOn" ], // conceptPlayerMoveOn
		g_rr.CriterionIsNotCoughing,
		[ "Who", "Coach" ],	// isCoach
		g_rr.CriterionIsc6m3_port
	],

Response examples

Confirm:Does onFinish work? Might not be implemented as said here: onFinish = eventually, a script function to call when the scene finishes (currently not implemented).

responses = [
	{ scenename = "coach_see_smoker_1.vcd", // if a 'scenename' key is present, this is expected to be a 'scene' response
	  soundlevel = 80,
	  onFinish = @(query, speaker) speaker.smokersSeen += 1 // expected to be a function
	},
	{
	  func = ZombieFreakout // if a 'func' key is present, this is expected to be a 'do function' response 
	},
	{
	  func = @(query,speaker) speaker.PointAt( query.enemy ) // anonymous functions are ok too
	},
	{
	  scenename = "coach_see_smoker_2.vcd",
	  sndlevel = 90,
	  onFinish = SomeFunc
	}
],

responses = [
	{ 
		func = SetAwardSpeech	
	}
],

responses = [
	{ scenename = "scenes/Gambler/MoveOn01.vcd",
		followup = RThen( "self",  "DemonstrateScriptFollowup", {additionalcontext="whatever"}, 1.23 ) // dispatches a "DemonstrateScriptFollowup" concept back to self
		func = DemoWritingContextToCharacter
	}
],

RThen is a followup event like in the response system in TXT files. All followups need to expose a function and a 'delay' parameter.

The callable gets the following parameters: ( _target, _concept, _contexts, _delay )

RThen(
	"coach",  					// target
	"TLK_FOLLOWUP_WHATEVER", 	// concept
	{ foo = 1, bar = "flarb" }, // contexts to add to the followup  (may be null instead)
	1.5 						// delay
)

Query facts

Todo: Check if then descriptions are correct.

The following table lists the known query facts available when evaluating a response rule. Values shown are examples captured from a live response query.

Note: The keyvalues are changed if the mission file has "survivor_set" as "1" for L4D1 Survivors or "2" for L4D2 Survivors
