That's interesting, you focused on adding controls and I focused on adding control... [link] I shy from "for" loops, they suck up too much RAM (even after making them adjust dynamically for scope.) What version of flash did you make this in?
'for' loops suck up ram? lolwhat, i think you mean processing power. And without 'for' loops, programming something like this would be retarded, using dynamic arrays to update every object and constraint. as well as iterations to resolve collisions and constraints.
