Alternative Syntax
- Syntax:
- Boolean = a and b (Only available since Arma 2:OA v1.62.)
- Parameters:
- a: Boolean - Test condition or variable that returns Boolean.
- b: Code - Code that returns Boolean. It is not evaluated if a returns as false.
- Return Value:
- Boolean
Examples
- Example 1:
if ((alive player) and (_enemycount == 0)) then {hint "you win !"}- Example 2:
if ((count _array > 0) and {(_array select 0) == player}) then {hint "It works! Without lazy evaluation it would throw an error if array was empty."}

Just like the "or" command, the "and" command allows several conditions to be checked. Example:
if(alive player and speed player > 0 and _someOtherVar) then { hint"All three condtions are true" };The example above will check if the player is alive and if the player is moving and checks if _someOtherVar is true.
