2D Collision, how to keep shapes out of an area?

Hello Kangaroo Master.

Here is what I am trying to do.

  1. Keep the green shapes outside && in-touch with the red shape, do not overlap. Red shape must not deform or move or anything. It must be stationed as it is.

  2. I do not know what I am missing, in my approach, the red shape is deforming.

  3. Attached is the gh file.

F.Y.I, I am on Rhino5 64, GH 0.90076, K2.42

Using the Kangaroo in R5, you can avoid the red shapes deforming by using CurvePointCollide. Since any overlap here would have to involve a point from a green shape being inside the red shapes. This goal treats the curve as a static input, so it won’t deform.

…in Rhino 6 though, all the collisions and shape preservation are done by one component:

and preserving the orientations is just a matter of adding a support:

Thank you for the reply. Master of Kangaroo.

I have downloaded R6, after installing, run gh, trying to load your curvecollide_r6.gh Rhino gives me this window.

After Rhino re-starts, pressed the gh again, Rhino gives me the same Unrecongnized Objects window.

Am I missing something?

Thank you again for looking into this.

I think you can open the R5 in R6 because it also works in R6
