I can't seem to wrap my head around this and it's driving me nuts.

I want to toggle on or off numbers 1-5 then select randomly from what is toggled on.

So let's say numbers 1, 3, or 5 are toggled on. I want to randomly select one of those numbers.

It seems simple enough but I've been fiddling for hours please help

I came up with a pretty complicated solution, but it seems to work. Here it is both as an image and an attachment.

randomly_select_toggled_values.pd

@zillaomg here's a simpler but maybe more cpu and memory-hungry version (bc you have to clear and repopulate a [list store] and [bag] every time, and use [pipe])

@zillaomg Using the abs library...... always worth a look as mainly very useful abstractions (so still Vanilla Pd)......
try.zip
You an remove repeats of the random selection if you wish.
The bang in the middle was connected after the [pack] ...... order of operations.
CPU..... no idea.... but the selection list will always need to be re-built when a toggle is updated.

@zillaomg Ty all!

I actually got it working with the list-abs library using list-nth but it was stupid complicated.

Your solution(s) are much more elegant. @whale-av's is exactly what i'm looking for ty!

@zillaomg And one using messages and no abstractions just for fun and completions sake, should be fairly efficient, Could be reworked for [list store] without much effort but I have no idea if there is any advantage to that over messages.

@zillaomg He he he...piling on....
choose random toggle.pd

Edit: less cluttered way to set the array

I got 1 more too, after seeing @oid's I was inspired to make a hybrid of ours:

edit: actually you don't even necessarily have to use lists:

ahaha amazing thanks friends. my pd weaknesses have certainly been illuminated through this endeavor. I've usually been pretty quick at achieving a goal in pure data but apparently havent been using messages/lists or arrays/tables past to their full potential
