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:: Strings Arrays Locations HashMap Unit Control

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:: [1,2,3] in [[1,2,3], [4,5,6]]; // true - Arma 3 only
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 _onFoot = _unit in _unit; // vehicle _unit == _unit works // isNull objectParent _unit is even faster

Lou Montana: 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).
