[Closed] objectsets and single objects

Hello!

A really simple question:

normally I write things like

fn Bla objs =
(
for o in objs do () etc.
)

and then Bla ($ as array)

the problem is that it doesnt work with single object selections. I mean i could check for the class of the object but its not so neat… is there a way of turning a single object into an objectset? Or how do you clever people handle this?

Thanks in advance!

in the case of selected objects you can use “selection” as it returns the current selection as an array. so “bla selection” will always work

hOpe this helps,

This should do the trick:

fn Bla objs = 
(
  -- turn <objs> into an array if needed
  if classof objs != array and
     classof objs != objectset then
  (
    objs = #(objs)
  )

  -- just an example, this fn returns the object's names
  for o in objs collect o.name
)

-- examples
Bla $Box01
Bla #($Box01, $Box02)
Bla lights

Or, you could also write a function for it that can be used throughout your script:

fn makeObjArray objs = 
(
  if classof objs != array and classof objs != objectset then #(objs) else objs
)

fn Bla objs = 
(
  for o in (makeObjArray objs) collect o.name
)

Cheers,

or in some cases you use a mapped function,


mapped fn randomcolor obj=
(

r=(random 0 255)
b=(random 0 255)
g=255-((r+b)/2)
obj.wirecolor=(color r g b)
)
