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, 6).

Since Arma 3 you can test for arrays within arrays.
Groups:: Uncategorised

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;
Example 6:: _isInString = "foo" in "foobar"; // true _isInString = "Foo" in "foobar"; // false

SilentSpike: 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;
