Gah! Coder's block!

I need to add 'something' to control enemies shooting patterns and behaviour, which needs to be fairly flexible but easy to configure. I've been staring at it for a week or so now and I'm still no closer to comming up with a good idea of how to do it.

Actually, "flexible but easy to configure" just screams out "object factory" so maybe I'll start there. Probably with some kind of simple manager to share out created objects...
