Where does he cover the UFO's abilty to spin?

Where does he cover the UFO’s ability to spin when it collides with walls and is also moving? Does he at all? His UFO spins when it hits walls moving. Mine doesn’t.

I’ve gone through these tutorial again, and I’m still missing it. Chances are there is something I’ve missed in the tutorials. But maybe the spinning is automatic and I’ve turned it off.

Is there any assistance offered?

I tried it again and this time got success as a result! Ignore these posts please.

Heh-heh. Any idea how I delete this post? Will it just delete itself after long enough with no updates?
