Description
- Description:
- Returns true if one or both conditions are true. In case of the alternative syntax, lazy evaluation is used (if left operand is true, evaluation of the right side is skipped completely).
- Groups:
- Uncategorised
Syntax
- Syntax:
- a or b
- Parameters:
- a: Boolean - test condition or variable
- b: Boolean - test condition or variable
- Return Value:
- Boolean
Alternative Syntax
- Syntax:
- a or b (Since Arma 2:OA v1.62)
- Parameters:
- a: Boolean - test condition or variable
- b: Code - code that returns Boolean; it is not evaluated if a returns true
- Return Value:
- Boolean
Examples
- Example 1:
if (_obj1 or (_enemycount == 0) or (not alive _enemyGeneral)) then { hint "you win !"; };- Example 2:
// without lazy evaluation select would throw an error if array was empty if ((count _array == 0) or { (_array select 0) != player }) then { hint "It works!"; };
