Description

Description:
Checks whether value is in array, unit in vehicle or position inside location.
ⓘ
String value in array check will be compared on a case-sensitive basis (see Example 2).
Arma 3
Since Arma 3 you can test for arrays within arrays.
Groups:
Uncategorised

Syntax 1

Syntax:
value in array
Parameters:
value: Anything - any value (Arma 2 cannot match Array)
array: Array - array of values
Return Value:
Boolean

Syntax 2

Syntax:
unit in vehicle
Parameters:
unit: Object - person
vehicle: Object - transport
position: Array - format Position2D or Position3D
location: Location
Return Value:
Boolean

Syntax 3

Syntax:
position in location        (Since Arma 3)
Return Value:
Boolean

Examples

Example 1:
1 in [0, 1, 2]; // true
Example 2:
private _myArray = ["Aaa", "AAa", "AAA"]; "aaa" in _myArray; // false "AAa" in _myArray; // true // case-insensitive alternatives _myArray findIf { _x == "aaa"; } != -1; // true _x count _myArray > 0; // true, less performant but valid before findIf
Example 3:
Arma 3:[1,2,3] in [[1,2,3], [4,5,6]]; // true
Example 4:
_isInCar = player in car;
Example 5:
_isInside = [1000,2000,0] in myLocation;

The Object syntax of in might not behave as you would expect (e.g. it would always return true) when both parameters are the same object . It serves as a quick method of checking if a unit is mounted: private _onFoot = _unit in _unit;
