I'm not sure why this isn't working. Can somebody please help?

I tried to rebuild the Dynamics Body Tag File setup you posted, but mine isn't working. The Dynamic Collisions node isn't returning anything for the Object index A or B except -1. I've poured over the scene Teknow posted, but cannot find any reason why my version isn't working. Weirdly, when I updated my IntroAni_v01c file, it works, although the Index B value goes way higher than I think it should. What am I doing wrong? Thanks for the help!

I attached my scene file for context. I checked out both files, and have some follow up questions. The first one, with the Dynamic Body Tag node, looks more like what I'm trying to build, with a few changes. Is there a way to make the clones change color permanently, so the color change happens once? I know one can track how many collisions happen, but can one track how many times a single clone collides? I've also seen a rig that cycles through Material indexes to change an object's color. If I could get the clones to change colors once when they collide with each other, and clamp the Material index value so it can't keep increasing over the one I want, that should work. I'm not sure what's going on in the second file you posted. Can you please explain what's going on there? Thanks! IntroAni_v01c.c4d

Thank you teknow! I was just about to send you a message. I'll take a look at both of these c4d files and get back to you.

Thank you for the reply! Can you please elaborate on the Dynamic Body State node setup you are referring to? What steps are involved in setting that up?

Anybody?

Hey Everybody, I'm trying to build a rig with Xpresso that causes individual, dynamic cloned spheres to change color when they collide with each other. I figured out how to change all the clones color when any of them collide, and how to identify the index of each clone. I'm not sure how to connect these two Xpresso scripts, or if this is possible with just Xpresso. I'd really appreciate help making this rig. Thanks! Karl
