[Closed] Allow only point helper?

Feb 16, 2005 6:37 pm

Hi,

I don’t know how I can solve this problem so please give me some advice.
I want to know how I can tell script that I want allow only point helpers for my selection. I think “classOf selection” is my problem, but don’t know what is right way…

    on adjust_spn changed val do
       
           if classOf selection==point then $.size = adjust_spn.value else messagebox "Please, select point helper!"

Thanks for helping.

Hi Tak Tak,

Here’s an example, I hope my comments explain it well

on adjust_spn changed val do
(
   -- collect all point helpers from selection into an array called 'thePoints'
   local thePoints = for obj in selection where classof obj == point collect obj

   -- any point helpers found in current selection?
   if thePoints.count > 0 then
   (
      -- change size of all selected point helpers
      thePoints.size = [b]val[/b]
   )
   else
   (
      -- no point helpers in current selection
      messagebox "Please, select point helper!"
   )
)

Regards,
Martijn
