I have been trying this for a while now and am not getting anywhere... hope someone here with fresh eyes can help me out!!

I have a grid of spheres and I would like to be able to drop random ones. So far so good. I use jit.phys.multiple and jit.gl.multiple. I set the mass of all objects to 0, @filters none (I don't want the spheres to interact with each other), then randomly set the mass back to 1...

What I would like to happen next is that once a sphere has left the FOV that it is removed from the physics engine. I was trying to set the mass back to 0 but couldn't make it work. Also, each time I make another sphere fall, all previously fallen spheres reset and fall again... How do I tell jit.phys.multiple to ignore certain spheres and keep them at their current position off screen? Is there a good way of achieving this?

Here is the patch. Thanks so much in advance!!!

I have a grid of

jit-phys-multiple-change-mass-of-individual-object

you'd probably be interested in the "sendbody" message. search the file browser for "phys.multiple.sendbody.maxpat"

Thanks, will have a look at this one again!

jit.phys.multiple change mass of individual object?
