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.
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 v1.98)
- Groups:
- Triggers
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 v1.44)
- 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.
