i downloaded it from mail-archive, and it seems to work for me.

thanks! i didn't think of this. i was trying to set the simulation
conditions, and the surface parameters to increase friction.

probably there's no interface for this in fluxus. i gave up to solve
this problem for a while, because it seems we have to add some more
functions to make this work. it would be worth to look into the physics
code sometime anyway, because ode 0.10 complains about normalization and
scripts with physics do not work anymore.

best,
