As of ["Arma 3","Arma3",152,132676,"Stable",true] this command is still broken if checking against markers that have axisB larger axisA.
To get around this if needed you can create your marker with the largest radius in axisA and rotate your marker by 90degrees.

Description

Description:
Detects whether position is within area or calculates distance to the nearest edge of trigger area by using optional params.
Arma 3
Since Arma 3 v1.57 inArea is available for an area check.
Execution:
call
Groups:
Object Manipulation

Syntax

Syntax:
[area, position, returnDistance, includeFloorCeiling] call BIS_fnc_inTrigger
Parameters:
area: Object, String, Location or Array
  • Object - trigger
  • String - marker
  • Location - location
  • Array - in format [center, distance] or [center, [a, b, angle, rect]] or [center, [a, b, angle, rect, height]]
position: Object or Array - position to check (e.g. player) or Position
returnDistance: Boolean - (Optional, default false) true to return distance to nearest edge of trigger area
includeFloorCeiling: Boolean - (Optional, default false) to include trigger area floor and ceiling in calculation when calculating distance to nearest edge
Return Value:
  • Boolean - true when position is in area, false if not
  • Number - (when returnDistance is true) - distance from closest border: negative distance - from inside, positive distance - from outside

Examples

Example 1:
private _trigger = createTrigger ["EmptyDetector", getPosATL player]; _trigger setTriggerArea [10, 10, 0, false]; _inTrigger = [_trigger, player] call BIS_fnc_inTrigger; // _inTrigger = true

Additional Information
