Nevermind, I see hp = x, sp = y now.  By the way, is_animated is
0, as copied from pit.arc.  I don't know what that

Also note that now the console gives:

[Error]   Object lacks animation.
[Error]   arch manhole_closed_3a

I'm not sure the change is made in svn is correct.  is_animated
is 0 because it is not continually animated but triggered (I
think, and going by pit.arc).

The error message goes away if I put is_animated 1 in the arch,
even though pit arc doesn't use it that way, but the animation
still doesn't work.

I've committed an update to the world_105_115.patch and to the
arch files to better explain the different cases.  There are
six examples now.  None of them work correctly even though 4
of them have a functioning animation.
