Description

Description:

Creates a sensor (trigger) of the given type and at the given position. The type must be a class name in CfgNonAIVehicles or CfgVehicles with simulation = detector. An array containing all units that have activated the trigger is available via list triggerobj. Created triggers can be deleted using deleteVehicle.

ⓘ

Since Arma 3 v1.43.129935 triggers can be created locally on clients setting optional param makeGlobal to false

ⓘ

Since Arma 3 v1.53.132440 triggers can be disabled/enabled using enableSimulation command

Triggers are created with default params, which are:

• a: 50.0
• b: 50.0
• c: -1
• angle: 0
• rectangular: false
• activationBy: None
• activationType: Present
• repeating: false
• timeoutMin: 0
• timeoutMid: 0
• timeoutMax: 0
• interruptable: true
• type: None
• text: ""
• name: ""
• expCond: "this"
• expActiv: ""
• expDesactiv: ""
• interval: 0.5 (Cannot be accessed via editor, scripted only since Arma 3 v1.97.146056)

Syntax

Syntax:

createTrigger [type, position, makeGlobal]

Parameters:

[type, position, makeGlobal]: Array

type: String - usually "EmptyDetector"

position: Position2D, Position3D or Object

makeGlobal (Optional): Boolean - locality flag (available since Arma 3 v1.43.129935)

• true (Default) - trigger is global Template:EffArg
• false - trigger is local Template:EffArg

Return Value:

Object - created trigger

Examples

Example 1:

_trg = createTrigger ["EmptyDetector", getPos player]; _trg setTriggerArea [5, 5, 0, false]; _trg setTriggerActivation ["CIV", "PRESENT", true]; _trg setTriggerStatements ["this", "hint 'Civilian near player'", "hint 'no civilian near'"];

Example 2:

Open/close Bar Gate automatically: //--- init of the Bar Gate if (isServer) then { _gateTrigger = createTrigger ["EmptyDetector", getPosWorld this, false]; _gateTrigger setVariable ["BarGateObj", this]; _gateTrigger setTriggerActivation ["ANYPLAYER", "PRESENT", true]; _gateTrigger setTriggerArea [5, 25, getDir this, true]; _gateTrigger setTriggerStatements [ "this", "thisTrigger getVariable ""BarGateObj""; animateSource [""Door_1_sound_source"", 1]", "thisTrigger getVariable ""BarGateObj""; animateSource [""Door_1_sound_source"", 0]" ]; };

Calling list immediately after creating a trigger this way (and setting up activation, area, statements, timeout, etc..), will return <null> instead of an array. It seems the trigger needs about 1 second to initialise, after which it will behave as expected: returning an array of all the objects inside the trigger (the ones matching the criteria), or an empty array.
