Coding wise it would be similar to what I'm already doing in game, just a little different as the editor doesn't use the parent/child structure, and really it's just a bunch of good ol' trigonometry to get the pieces to rotate around a radius.
So do you program actionscript too?
Btw, i like your 12 o'clock shuffle, and your stopping rotation trick is neat too. It's awesome seeing the 'hacks' (not really) you guys come up with, in fact, there's still one i'm surprised no one's discovered yet...hehe...
swartzer, item grouping is coming! I've already got grouping working with moving multiple part, just no rotation yet.
In the end, rotating everything would require selecting each part, so having the core rotate every part around it might still be useful...of course, ideally the grouping would work like it does in operating systems, click and drag a selection box...maybe one day.
Once Christmas break comes and all my exams are done I can dedicate some time to Zeta Flow, then I will implement as much as I possibly can
