Select CatParent in MaxScript

[wagnerdesouza]

How i can check if my object in the selection is a CatParent and not a CatBone?

Thanks

Assuming a single object selected:-

if classof selection[1] == CatParent then
   -- it's a cat parent
else
   -- it's not

Yes! I have just one object selected. 

Great, i will try this!

Thanks

Works fine! Thanks!

What is the number 1 inside of selection[] ?

And, do you know the diference between Cat_Parent and CatParent?

Selection is an inbuilt array (well, technically a collection, but...) so if there's only 1 item selected it is in the 1st element of the array. [1] is an array index. Essentially the same using "$" i.e. classof $

Select an object, open the Maxscript Listener and type in "classof $" - if the selected object is a CatParent then that is what is displayed - literally. Also, the help has no entries for "Cat_Parent" but does for "CatParent" which is a bit of a clue 🙂

Cool, 

I understood, i was using $.

I tryed different ways ex.:

if $.category == CatParent then

if $.category == Cat_Parent then

if $category... etc

But the key was classOf 🙂

Next step is to parse the string of layer name of cat to set the timeline range 🙂

Iam very newbie in maxscript, so i have some doubts

Thanks for help!

Category is a somewhat different animal. Think of them as "groups" of objects of a similar type. A Box is part of the "#Standard_Primitives" category, a CatParent is part of the "#CAT_Objects" category and so on. Categories have their uses (they're used by the Display Panel "Hide by Category" for example) but aren't really specific enough for what you need in this instance.

Usage would be :- if $.category == #Standard_Primitives then...
