Description:: Checks if argument a is equal to argument b. Both arguments need to be of the same type. Comparing Numbers or Strings has higher priority than comparing other types. String comparison is case-insensitive. If you need case-sensitive comparison use isEqualTo command.
Groups:: Uncategorised

Syntax:: a == b
Parameters:: a: Group, Side, Object, Structured Text, Config, Display, Control, Location
: b: Group, Side, Object, Structured Text, Config, Display, Control, Location
Return Value:: Boolean

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:: ? name player == "Billy" : hint "Hello Billy, how are you?"

Ceeeb: In OFP v1.96, comparison of strings is not case sensitive. Example : "STRINGtext" == "stringTEXT" returns true.; Posted on Apr 15, 2014 - 15:34
ffur2007slx2_5: (A3 1.16) for case sensitive comparison, array comparison and boolean comparison we can use switch do. e.g. switch (_var0) do { case (_var1) : {true}; default {false}; }; 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; // false And we can use such workaround instead of using BIS_fnc_arrayCompare or BIS_fnc_areEqual
