Thank you for the code! Very helpful. Now all I have to do is decide which method to use and get testing.

One final thing about ph_cylinder. Im running this:

phent_settype(me, ph_rigid, ph_box)
phent_mass(me, ... , ph_cylinder)

This works, I think but I'm not sure why. And why makew two physics settings only for static objects???

For some reason, my ambition always seems to beat my ability.
