Hi, I am trying to have closed polylines repelling each other inside a boundary rectangle. For that I was planning to sample a certain amount of equidistant points along the polylines and set a repulsive force for each of them. The problem is that the Kangaroo solver seems to process each polyline…

It looks like you need to flatten the Points input to the collider. This lets it process them all together as one list instead of lots of separate lists. As for keeping them all in a rectangle, you can use an OnMesh goal with a mesh of a single quad face. If you want there to be a border, you can i…

Thank you so much for the prompt reply, it helped a lot !
