Checking Selection Set Contents

[Anonymous]

This is an extremely simple question but I'm working on making some scripts I've written more robust. What is an efficient way to determine if a set of objects selected via code is empty or not. I'm sort of assuming it's some variation on checking whether or not the selection set is null?

Many thanks in advance.

if selection.count == 0 do ...

Do you mean checking if named selection sets are empty? You can do it like this:

if selectionsets == undefined or selectionsets.count == 0 then
    print "empty or non-existent."

If you're using a numeric index into the selection sets, you can check it versus selectionsets.count instead of checking if selectionsets is undefined.
