isEqualTo

Description

Performs strict comparison between var1 and var2 and returns true if equal, otherwise false. Strict means that it would check that both arguments are of the same data type and then compare the values.

Some differences between isEqualTo and ==:

• It performs case sensitive comparison on Strings
• It doesn't throw error when comparing different types, i.e. ("eleven" isEqualTo 11)
• It can compare Arrays, Script Handles and Booleans (alive player isEqualTo true)
• It can compare non-existent game objects (grpNull isEqualTo grpNull)
• It is slightly faster than ==, especially when comparing Strings
• Arma 3 v1.48 It can compare Namespaces

Note

A compiled code is not equal to the same compiled code made final:

_a = compile "123"; _b = compileFinal "123"; _a isEqualTo _b; // false

Warning

When comparing Arrays, if an array contains nil element, the comparison will return false. For example:

private _array1 = [1, nil, 2];
private _array2 = [1, nil, 2];
_array1 isEqualTo _array2; // false

UNLESS the compared arrays are the same array:

private _array1 = [1, nil, 2];
private _array2 = _array1;
_array1 isEqualTo _array2; // true

Syntax

val1 isEqualTo val2

Parameters:

• val1: Anything
• val2: Anything

Returns: Boolean

Examples

Example 1

_arr1 = [1, [2, [3]]];
_arr2 = [1, [2, [3]]];
if (_arr1 isEqualTo _arr2) then { hint "Arrays match!" };

Example 2

if (a isEqualTo b) then { hint "a is equal to b" };
if !(a isEqualTo b) then { hint "a is not equal to b" };
