Better way to access dropdownlist values in Maxscript,

Tools 3ds Max

Hello,

I’ve been having a few issues with the dropdownlist menu item in Maxscript. Basically, I have various values (mainly float values) in a dropdown list that the user can select. If I use basically “<dropdownlist>.selection” I get the number of the item in the array, so far example if I had something like this,
(random example)

#("1.0", "5.5", "10.4", "20.8", "50.5","100.1", "200.05")

and I want to get the value contained in the selection, using “.selection” returns the number of the item, but not the actual value it contains (so instead of 100 I would get 6 instead of 100).

To “fix” this I just use a case statement which works fine, but seems a bloated way of doing things.

So is this a syntax/logic error on my part, or something else?

Thanks for your time. :slight_smile:

Jonathan,

Use the index returned by selection to access the data from the items array of the dropdownlist.

	dropdownlist test "test" items:#("A","B","C","D","E","F","G","H","I","J") height:6 
	button btn_test "get selection"
	
	on test selected i do
	(
		print	test.items[i]
	)
	
	on btn_test pressed do
	(
		print test.items[test.selection]
	)

or you can use the .selected property of the drop down list control which returns the value of the selected item and not its index.

Thanks for the responses. Cannot believe it was that simple, just needed “selected” instead of selection. Woot! (works if you cast it as an integer or float, i.e.- “~.selected as integer”)

Thanks again.
