Armed Assault


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.

NOTE1: Since Arma 3 v1.43.129935 triggers can be created locally on clients using the alternative syntax.
NOTE2: 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
  • 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 - ""


createTrigger [type, position, makeGlobal]
[type, position, makeGlobal]: Array
type: String
position: Position2D, Position3D or Object
makeGlobal (optional): Boolean - locality flag, true - trigger is global Effects of this scripting command are broadcasted over the network and happen on every computer in the network, false - trigger is local Effects of this scripting command are not broadcasted over the network and remain local to the client the command is executed on (available since Arma 3 v1.43.129935)
Return Value:


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'"];

Additional Information

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.
