Rollin' vs. Mashin'

I put a physical ball on a non-physical cube. I put a script in the cube that rotates the cube slightly. Shouldn't the ball roll off the cube?

If I lower the cube using llSetPos, the ball just hangs suspended in mid-air. If lift the cube, it passes into the ball without any collision events.

Is there some way of telling a physical object that it ought to update its notion of the world? For example, if it isn't sitting on something solid it should let gravity do its thing and fall until it is?

When a physical object settles down (stops moving) then the physics become disabled until it's given a knock again by an avatar or another physical object.

You could put a script inside the ball to keep it active. A script that gives it a little nudge now and then.
