Hi all, a quick little question: is there any way to get properties from uninstantiated MovieClips? that is, I have a thumbnail MC in the library. I want to get its width before I instantiate it. I know it’s kind of a stupid question, but I’m trying to optimise my code and that would prevent a bunch of extra calculations. Thanks in advance!
