Description

Description:
Checks whether value is in array, unit is in vehicle, position is inside location or ANSI string is part of other ANSI string. If Unicode support is desired, see forceUnicode.
ⓘ
String comparison is case-sensitive (see Examples 2 and 6).
Groups:
StringsArraysLocationsHashMapUnit Control

Syntax 1

Syntax:
value in array
Parameters:
value: Anything - any value (cannot match Array before Arma 3)
array: Array - array of values
Return Value:
Boolean

Syntax 2

Syntax:
unit in vehicle
Parameters:
unit: Object - entity person
vehicle: Object - entity vehicle
Return Value:
Boolean

Syntax 3

Syntax:
position in location
Parameters:
position: Array - format Position2D or Position3D
location: Location
Return Value:
Boolean

Syntax 4

Syntax:
needle in haystack
Parameters:
needle: String - string to search for
haystack: String - string to search in
Return Value:
Boolean

Syntax 5

Syntax:
key in hashMap
Parameters:
key: HashMapKey
hashMap : HashMap
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 the introduction of the findIf command { if (_x == "aaa") exitWith { 1 } } count _myArray > 0; // true { _x == "aaa"; } count _myArray > 0; // true, worst performance, only option available in OFP
Example 3:
[1,2,3] in [[1,2,3], [4,5,6]]; // true - Arma 3 only
Example 4:
private _isInCar = player in Car;
Example 5:
private _isInside = [1000,2000,0] in MyLocation;
Example 6:
private _isInString = "foo" in "foobar"; // true _isInString = "Foo" in "foobar"; // false
Example 7:
private _onFoot = _unit in _unit;
Other options:
private _onFoot = vehicle _unit == _unit;
private _onFoot = isNull objectParent _unit;

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).
