listbox items access

[SoLiTuDe]

hey all.
I want to access individual items from a listbox so they do a specific operation one by one.

check out my test

"for o in fragments.items do" seems to be wrong :/

Here's how I would do it... keep in mind I didn't test this. Just going on the fly here.


rollout booM "b o o M "
(

group "Fragments"
(
Button addsel " add selected"
Button resetlist " reset the list"
MultiListBox fragments "Fragments" --items:(for o in selection collect o.name)
)

Button test " Test"

local fragobjs = #()

on booM open do --sets stuff when the rollout opens
(
fragobjs = selection as array
fragments.items = (for o in fragobjs collect o.name)
)

on resetlist pressed do
(fragments.items = #())

on addsel pressed do --reset list basically
(
fragobjs = selection as array
fragments.items = (for o in fragobjs collect o.name)
)

on test pressed do
(
for o in fragobjs do --fragments.items is just an array of strings, not objects!
(rotate o (eulerangles (random 2 -2) (random 2 -2) (random 2 -2)))
)

)

createDialog booM

It is, your problem is that the items array in the multilistbox does not hold the actual scene items but an array of string names (the one you created in "for o in selection collect o.name"). When you try to rotate the string the script obviously throws an error. The most direct solution is to have a local variable in the rollout that holds the items themselves, that can be referenced using the multilistbox; which is basically what SoLiTuDe coded up for you.
