Syntax
- Syntax:
- Syntax needed
- Parameters:
- booleanA: Boolean - test condition or variable
- booleanB: Boolean - test condition or variable
- Return Value:
- Return value needed
Alternative Syntax
- Syntax:
- boolean && code Template:Since
- Parameters:
- boolean: Boolean - test condition or variable
- code: Code - code that once executed returns a Boolean. The code is not evaluated if boolean is false.
- Return Value:
- Boolean
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!"; };
