evalMacro() Function
Note: This function can only be used in a Trusted Macro
The evalMacro() function executes the macro in the same variable scope (i.e. the executed macro can read and alter variables from the current macro), where as execMacro() creates a new variable scope (i.e. the executed macro can neither read nor alter variables from the current macro).
If you are performing rolls in the macro that create tool tips or use [e: ]
then you will have to use either { }
or [r: ]
to display the output, otherwise you will get incorrect formatting.
"3+5"
), while with evalMacro() you can give anything as a parameter, but only the parts between [
brackets]
will be evaluated, e.g. "Your resulting roll is [r: 1d10]"
.Usage
evalMacro(macroString)
execMacro(macroString)
Parameter
macroString
- The string containing the macro script that is evaluated/executed.
Examples
[h: setNotes(evalMacro('[r,macro("CreateNotes@Lib:Notes"): ""]'))]
Sets the Notes of a Token to the output of the CreateNotes
macro located on the Lib:Notes
Library Token.
[r: evalMacro("[h: TestVar1 = 5][h: TestVar2 = 10][TestVar1+TestVar2]")]
Returns 15
[h: TestVar3 = 10]
[h: TestVar4 = 20]
[r: evalMacro("[TestVar3+TestVar4]")]
Returns 30
[h: TestVar3 = 15]
[h: TestVar4 = 30]
[h: evalMacro("[TestVar5 = TestVar3+TestVar4]")]
[TestVar5]
Returns 45
[h: TestVar6 = 20]
[h: TestVar7 = 40]
[r: execMacro("[TestVar6+TestVar7]")]
Prompts for the values of TestVar6
and TestVar7
, then it returns the sum of those two values.
[h: TestVar8 = 50]
[h: TestVar9 = 100]
[h: TestVar10 = 0]
[h: execMacro("[TestVar10 = TestVar8+TestVar9]")]
[TestVar10]
Returns 0
[r: evalMacro("[h:roll=1d20]You roll [r:roll] and you [r:if(roll<10, 'hit', 'miss')] your target.")]
You roll 3 and you hit your target.
