[if():] Roll Option
* Introduced in version 1.3b46
Branches the flow of the roll as determined by the condition.
Usage
[if(condition): true_body][if(condition): true_body; false_body]Parameters
condition- The condition/s to check to determine which roll(true_bodyorfalse_body) is executed, if any. The condition/s can only contain one level of nested parenthesis.true_body- The roll that is executed if theconditionevaluates totrue(1). To use complex rolls in thetrue_body, you must use the [code():] roll option in conjunction with this roll option.false_body- The roll that is executed if theconditionevaluates tofalse(0). If nofalse_bodyis given, there is no output if theconditionevaluates tofalse(0). To use complex rolls in thefalse_body, you must use the [code():] roll option in conjunction with this roll option.
Operators
Operators are used to compare two variables, strings, literal numbers, expressions, or function outputs within a condition.
Conditional Operators:
>- Greater than<- Less than>=- Greater than or equal to<=- Less than or equal to==- Equal to!=orne- Not equal
Logical Operators:
&&- And||- Or
Boolean Operators:
truefalse
It is important to note that the Equal to condition operator must be two equal signs(==). If you are checking for a text string, place quotes around the text.
Example
Sets the variable newVal to 12*12 if the variable val equals 12.
[h:val=12]
[h,if(val == 12): newVal=12*12]
New Value = [r: newVal]Returns New Value = 144
