Description
- Description:
- Returns true only 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). Identical to: a or b
- Groups:
- MathVariables
Syntax
- Syntax:
- a || 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:
- a || b Template:since
- Parameters:
- a: Boolean - Test condition or variable that returns Boolean.
- b: Code - code that returns Boolean. It is not evaluated if a returns true.
- Return Value:
- Boolean
Examples
- Example 1:
if ((OBJ1) || (_enemycount == 0)) then {hint "you win !"}- Example 2:
if ((count _array == 0) || {(_array select 0) != player}) then { hint "It works! Without lazy evaluation it would throw an error if array was empty."; };
