Is this possible? I made a class and registered it to a movieclip in the library, but when I do it this way the tweening prototypes no longer work. Is there any way to have both?

EDIT: If I give my class Extends Movieclip it works (I guess cause then they can work together? It still won’t let me put something like slideTo(100,100,2); in the class, while \_x = 100 or standard movieclip methods\properties work. Anyone know why that is?
