booleanA: Boolean - test condition or variable
booleanB: Boolean - test condition or variable
Return Value:
Boolean

Alternative Syntax

Syntax:
boolean && code
Parameters:
boolean: Boolean - test condition or variable

Examples

Example 1:
private _allEnemiesKilled = true; if (alive player && _allEnemiesKilled) then { hint "you win !"; };
Example 2:
if ((count _array > 0) && { (_array select 0) == player }) then // an error would be thrown without lazy evaluation { hint "It works!"; };
Example 3:
if ((alive player) && { player setDamage 0.5; true }) then // valid AS LONG AS the code block returns a Boolean { hint "It works!"; };
