Hi all,

I was just wondering if the above is possible?

Say you have a simple copystamp operation on a grid.
Your random rotation on the stamped copies is set to rotvar = fit(360*rand($PT),0,1,-180,180).
This all works fine.

If I pack the setup into a subnet, is it possible to replace the -180,180 with sliders and link those back into the expression?
e.g. I made two (integer) sliders in the subnet UI named minrot (-180<–>0) and maxrot (0<–>180), and linked them back into the expression:
rotvar = fit(360*rand($PT),0,1, ‘../../subnet/minrot’, ‘../../subnet/maxrot’)

There's no errors, but the sliders in the subnet aren't working. I feel I'm close, but missing something here


cheers for any tips, links etc.

If it is not working as you have tried consider moving the fit into an attributeWrangle and referencing channels instead. You will need to create an attribute instead of a variable then reference that attribute in the stamps instead.
Click on the little side button to create the additional channels on the attributeWrangle. Now you should be able to use a relative reference on the min/max channels from the higher level.

Hi,

Thanks for that!

So it - should- have worked as described? I'll fidlle a bit more to see if I can get it to work.
I will also dive into the AttributeWrangle and channels. Always a good thing to have multiple options

cheers!

After some more RTFM and some testing with dragging and dropping parameters, I found the culprit.

The driving parameter should be referenced as a channel as well.
So instead of ,“../../subnet/minrot”, it should read ,ch(“../../subnet/minrot”),

Works like a charm now!
