      However, I find it preferable to look at a map someone else did, look at the

      A simple solution here would be to have a function like

     'find_mover_object_match' or the like, which takes a teleporter/mover/exit (and

Ok, that makes sense.

I'll just be sure that the fields that I do my matching against won't touch
those that will be used by movers, teleporters, and such.

Just to be clear: I'm using a new object type (63, which was unused) for my
new mover.  The plan is to get it fully-tested (it's already working for
the cases I've tried), and get it included in the server.  The next step is
to create new arch types for the new mover (and set up crossedit to make
them available).  Then I convert the existing maps over from using the old
mover to using the new mover.  Then, if everyone is happy, we eliminate the
old mover and associate arch types.



Now I have some questions about the code.

As it is now, the mover works by having a speed.  As I understand it, that
means that it will periodically scan through all the objects above it and
move them if they match the move criteria.  If I drop a few hundred
non-matching items on a mover, this could be bad for performance.  It would
make a lot more sense to have the object activated anytime something
changes on that square that might matter.  How should I go about this?

Someone suggested the possibility of having a mover have a connected value.
Can someone give me an outline of how the code handles connected objects?


Thanks!
