Suppose I wish to generate stripes with random widths.

I can, right now, manually create a series of [translateXYZ] --> [rectangle] objects and, with the right numbers, I do get stripes.

But maybe sometimes I need 3 really fat stripes and other times, 20 narrow ones. Or I want to fill up a total distance of 1.5 with randomly-sized stripes and random distances between them, so that the total number of stripes is not known in advance.

If every stripe must be an individual [rectangle], then I'm afraid I don't see how to do it.

High-level jiujitsu trickery is welcome

What a GREAT link! Thank you!!!

@whale-av I'm trying your [repeat] substitution but it seems not to work with gemlists.

etc.

Am I doing it wrong? Or are gemlists "special" somehow?

@ddw_music It is probably because the output is tagged as a list. I tried adding [list trim] and strangely the list tag remained.
Adding [f] after [list] will retag the repeated float as a float and then it should work for Gem (I hope).

Alas:

consistency check failed: gpointer_copy
inlet: expected 'float' but got 'pointer'
Couldn't convert gem_state to float.

It's funny... seems like this "should" work.

@ddw_music i think the error message makes sense, because you send the gem pointer to the second inlet of [translateXYZ] which expects a float.

@Jona "because you send the gem pointer to the second inlet of [translateXYZ] which expects a float."

I don't think so:

The [f] box is whale-av's suggestion above, to deal with a different error.

@ddw_music alright, i was refering to your last screenshot, now it looks different... sorry, i do not have a solution.

@ddw_music So [list] creates "gpointer_copy" errors from the Pd binary (use log debug mode to see).
And an abstraction will not accept gem_state messages travelling back up the chain as an external can do.
The gem_state will need to be looped like this........ iteration.zip
It's simple and I think it's safe.
David.

@whale-av I see, recursion is the only way, then. zexy is probably easier to explain to the students.

Thanks!
