jit.phys Patch-along, Part 2

Patch along with Jitter Developer Rob Ramirez as he works with the Jitter Physics system. In this multi-part series, Rob will go from creation of a physics world and rigid bodies to using constraints and building and simulating complex structures. This second video shows how to work with constraints to create a Newton’s Cradle simulation.

I’m trying to make this patch but the jit.phys.body won’t give me the collisions attribute. I have:

Also, the jit.phys.picker wont give me the enable attribute

Any idea why this is?
As you might be able to tell, I’m not an eagle on max yet, so apologies if there is a way to obvious answer for tihis.

you simply need to update to the latest version of max 6.
those features were not available in versions prior to 6.0.7.

Aha…. Great.

Looks like I’m new to downloads as well :)

Hi! I really like this patch along series. I was wondering why we need to lock the hinge to get a more realistic behavior. I tried to build it with three swinging balls, but it did not work very well. I think this is due to the fact that I do not understand why we need to lock the hinge… If someone has the Newton’s cradle working with more than two swinging spheres, I’d be very interested to hear how it was done…. Thank you! Hanna
