Hi all, I've created a shape that can interactly change by the user inputs. That is done by first attaching the shape to a branchgroup and then before new the inputs take changes, I detach the the branchgroup first. I just wanted to know if I'm making the right decision, I mean is it better using "removeChild" or "detach" ? What's the difference between the 2 methods ? because I want to use as less resources as I can. Thanks in advanced to everyone! Take Care and Keep Smilling!
