Really great advice there guys, thanks a lot :)
I had my suspicions it would be done like this, but needed to be
reassured by the Ninja's.
Luckily the game logic is separated from the display, in a similar way
to how you're describing.
I currently have multiple scrolling engines, each representing a layer
of parallax. I'm guessing I just need to duplicate a single 'terrain'
scrolling engine (which is never actually drawn) and combine it with the
necessary collision detection for each baddy that needs AI.
Cheers folks!

Separate your display code from your game logic.
One thing that I see frequently is people inheriting
directly from movie clips for their game objects. This
is bad because it encourages overuse of inheritance,
and makes display/game logic separation harder.
Usually, I'll have my game object as separate items,
with their own x and y properties, then a viewport
object for determining where you're looking. To
determine what gets displayed, I'll check to see if
the game object is within half a screen distance from
the viewport, and if it is, and not already displayed,
I'll attach a new movieclip, and position it relative
to the screen center by the distance from the viewport
to the game object.

Hello all,
When building a game where collision detection for
enemies is important
(such as a scrolling tile game), how do you create
persistent AI for an
enemy when it's off-screen?
For example, walking away from the enemy causes it
to be removed from
the game area, but the enemy needs to keep wandering
around the world in
virtual terms, so the player can't easily tell where
the enemy is going
to be when returning to the same area. How do you
maintain that
interaction for the enemy, or is it not done like
that because it's too
processor intensive?
Any tips or pointers to resources would be much
appreciated.
Thanks!
James
