is it possible to use hoopsnake in this case

Hi i'm trying to find the solution in simple script and i thought about hoopsnake to make it work. But after connection it seemed to make a loop empty and i don't understand why. How could I make it work. I'd like to produce a curve based on the points list which are given by the loop of evaluated circles. Thank You for any help.

Hi Adam,

In principle it is certainly possible. I didn't really understand your definition, but in any case you will have to supply a starting condition (the S input on Hoopsnake). Actually, the way it works right now, you will have to specify a starting condition even if you are not using it, otherwise you will will get empty outputs.

Cheers

Thank You Yiannis, it works with the starting condition (simple plane) but still im not sure if it works in the right way. I have found the question in the GH forum about the repeating GH script - if there is any way to make it without copy and paste the same part for many times. So i found Hoopsnake to be usefull in this case. Actually if it's possible to engage Hoopsnake in this case then it would make live much easier when we have to repet the same script over and over again instead just loop one unit. You can have a look at that post of Stamatis:

and btw thank You for this amazing tool - it change the way of thinking about creating the scripts on GH

cheers

Hi Adam,

yes, this is exactly the type of situation Hoopsnake was designed for. So, connecting the output of a single block of Stamatis' definition to Hoopsnake and it's output back into the block (the Plane component perhaps) should get you set. You should pay attention to two things then:

First, you should merge the output of the current iteration (after the eval) and the previous one (output of Hoopsnake) in order to get a series of points and not just the last one.

Second, I saw that there are different variables for each iteration in Stamatis' example, so for that you would require some way of setting them for each iteration, i.e. a random number generator or so.

Cheers,

Yiannis
