Description
- Description:
- Check if argument a is equal to argument b. Both arguments need to be of the same data type.
- Groups:
- MathVariables
Syntax
- Syntax:
- a == b
- Parameters:
- a: Number, String, Group, Side, Object, Structured Text, Config, Display, Control, Location, Diary Record (since Arma 3 v2.00), Namespace (since Arma 3 v2.00), Boolean (since Arma 3 v2.00)
- b: Number, String, Group, Side, Object, Structured Text, Config, Display, Control, Location, Diary Record (since Arma 3 v2.00), Namespace (since Arma 3 v2.00), Boolean (since Arma 3 v2.00)
- Return Value:
- Boolean
Examples
- Example 1:
if (player == leader group player) then { hint "You are the leader of your group."; } else { hint "Someone else is the boss"; };- Example 2:
"MyRabbit" == "MYRABBIT"; // returns true- Example 3:
- Since Arma 3 v2.00
if (alive _unit1 == alive _unit2) then {hint "Both units are either dead or both alive"};

For script comparison we need to detect whether scripts are running in advance, then compose both into string:
if (scriptDone _var0) then [{false},{(str _var0) == (str _var1)}];It is recommended to use isEqualTo for all types comparison, which is more functional and as fast as operator. For multiple comparisons:fnc_areEqual = { private ["_b", "_var1", "_var2"]; _b = true; for [{ _i = 1 }, { _i < (count _this) && _b }, { _i=_i + 1 }] do { _var1 = _this select (_i-1); _var2 = _this select _i; if (!(_var1 isEqualTo _var2)) then { _b = false; }; }; _b }; ["A","a","a"] call fnc_areEqual; // falseAnd we can use such workaround instead of using BIS_fnc_arrayCompare or BIS_fnc_areEqual
