Data Structures Being Changed when Using Hops

Grasshopper Hops
,
#1

Hi Everyone,

I was working on a script to find the inside or outside tangents circles or two input circles and wanted to test out using Hops for the first time. I have a working script that does what I need it to, but when I reference it as a Hops component, the script does not return anything. I believe it has something to do with the Hops component internally changing the data structures of my script because I have a work around in the script to check if a singular item or a tree has been input, and it only doesn’t work when I try to use trees. Has anyone had this issue before or know why it’s happening?

I’ve attached a file that shows the script exploded, packaged in a cluster, and referenced with a Hops component. I’ve also attached the separate Grasshopper script that is referenced in the Hops component.

Best,

Grant

I haven’t checked the definition, but have you checked the At Most setting on your Get Components (the ones that define inputs on the Hops component). The default is set to 1 which means its expecting you to pass in a single item. If you pass it in a list, then it will make a separate call for each item that gets passed in. If you unset the At Most value (meaning clear out the value), or set the number to some large integer, then it will treat the input as a list and only make a single call with the values your passing in. This value could be what’s causing the data structure to be different than what you’re expecting.

Thanks for the response, Andy! I’ll try it out.
