Modify Description on a component?

[TCArknight]

I'm back again with something that doesn't seem to be working...

I have a Skill component, and this eval script on the component:

<!-- Update description for each rank3+ with additional info -->
    <eval index="5" phase="Traits" priority="10000"><![CDATA[
      trustme
      var myDesc as string
      
      ~if this skill is not added directly to the hero (i.e. an advance), skip it entirely
      doneif (field[trtFinal].value <= 2)
      
      if (field[trtFinal].value >= 3) then 
        myDesc = field[descript].text
        myDesc &= "{br}{br}{b}Bonus: {/b}Reroll any single die when you take a Risk with this skill.{br}"
        field[descript].text = myDesc
        ~perform amendthing[descript,myDesc]
        endif
         
      ]]></eval>

That results in:

Hero Lab was forced to stop compilation after the following errors were detected:

Syntax error in 'eval' script for Component 'Skill' (Eval Script '#5') on line 11
-> Only derived fields can generally be modified via scripts (field 'descript')

If i try using the amendthing statement instead, I get this:

Hero Lab was forced to stop compilation after the following errors were detected:

Syntax error in 'eval' script for Component 'Skill' (Eval Script '#5') on line 12
-> Script reference is invalid under the circumstances

I created the appenddesc macro based on the posts elsewhere -

  <scriptmacro
    name="appenddesc"
    param1="thing"
    param2="append"
    result="perform state.thing[#thing].amendthing[description,#append & "{br}{br}" & state.thing[#thing].field[descript].text]"/>

If I try using:

 #appenddesc[this,myDesc]

it results in

Hero Lab was forced to stop compilation after the following errors were detected:

Syntax error in 'eval' script for Component 'Skill' (Eval Script '#5') on line 13
  -> Non-existent thing 'this' used by script

I'm at a loss with this, because it seems like the trustme should at least allow me to modify the descript field directly.

Am I missing something?

If a field is static, trustme will not override that - it only overrides the protections on user fields and persistent fields.

In your original script, you're still in a pick context - you haven't transitioned to state.thing[], and amendthing isn't valid on a pick.

state.thing[] must be given an Id. "this" is not a legal option, because it's not the Id of a specific thing - it's a path that leads to a pick context. Amendthing is not just modifying the current pick - you need to modify the thing that this pick is based on.

foreach thing in TheComponent where tagids[thing.?]
     perform eachthing.amendthing[description,"The Text"]
     nexteach

should work.

Actually, I'd add a new text field, and then in your mouseinfo procedures, write a standard bit just after where the procedure already adds field[descript].text, so that if that "Additional Information" field is not empty, it adds it to the text that's displayed. Skip the whole amendthing part.
