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.
if(condition, trueExpr, falseExpr)
Parameters
condition - What is tested to determine is the trueExpr or falseExpr will 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 if condition returns as true.
falseExpr - A section of code that is executed if condition does not return as true.
Example 1: If 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)]Returns: property set to 0
