if() Function
• Introduced in version 1.3b38
This function is used to check whether a certain code expression should be executed or not. If the condition to be evaluated with this function is
true, the first expression of code is executed, otherwise the second expression of code is executed.
Note: This function has been deprecated in favor of the if (roll option). Both trueExpr and falseExpr are evaluated regardless of what condition returns, so this should only be used in limited cases where a small branch is required within other functions.Usage
if(condition, trueExpr, falseExpr)Parameters
condition- What is tested to determine is thetrueExprorfalseExprwill be executed. This follows the standard rules for conditions that can be found in the Branching and Looping article.trueExpr- A section of code that is executed ifconditionreturns astrue.falseExpr- A section of code that is executed ifconditiondoes not return astrue.
Examples
Example 1: If
Returns:
a is 10 and b is 20:
[r: if(a > b, "A is larger than B", "A is not larger than B")]Returns: A is not larger than B
Example 2: If number is 1:
[r: if(number >= 1, 20, "")]Returns: A blank string, please note that a blank string is not an empty variable if you were to assign the output of this function.
Example 3: If variable is "Foobar":
[r: if(variable == "Text", 1, 0)]Returns: 0
Example 4: If variable is 20
[property = if(variable > 0 && variable < 20, 1, 0)]property set to 0
