Description

Description:

Checks whether value is in array, unit is in vehicle, position is inside location or string is part of other string.

ⓘ

String comparison is case-sensitive (see Examples 2 and 6).

Since Arma 3 you can test for arrays within arrays.

Syntax:

position in location        (Since Arma 3)

Parameters:

position: Array - format Position2D or Position3D

location: Location

Return Value:

Boolean

Syntax 4

needle in haystack        (Since Arma 3 v1.95.146032)

Parameters:

needle: String - string to search for

haystack: String - string to search in

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 ({ if (_x == "aaa") exitWith { _forEachIndex }; -1 } forEach _myArray) != -1; // true, less performant but valid before findIf { if (_x == "aaa") exitWith {1} } count _myArray > 0; // true { _x == "aaa"; } count _myArray > 0; // true, worst performance // only option available in OFP

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;

Example 6:

_isInString = "foo" in "foobar"; // true _isInString = "Foo" in "foobar"; // false

Example 7:

private _boarded = player in _groupVehicle;

Example 8:

private _onFoot = _unit in _unit; // isNull vehicle _unit works // isNull objectParent _unit is even faster

From a description note:
<unit> in <vehicle> literally does this: vehicle <unit> == <vehicle>. If <vehicle> is the same as <unit> the expression will return true for when the <unit> is on foot and false for when <unit> is in vehicle (see example 7 & 8).
