Description
- Description:
- Returns true only if both conditions are true. In case of the alternative syntax, lazy evaluation is used (if left operand is false, evaluation of the right side is skipped completely).
- Multiplayer:
- no special considerations
- Groups:
- Uncategorised
Syntax
- Syntax:
- Boolean = a and b
- Parameters:
- a: Boolean - Test condition or variable that returns Boolean.
- b: Boolean - Test condition or variable that returns Boolean.
- Return Value:
- Boolean
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.
