Hi,

I don’t know how to manipulate/access movieclips from a class file. Is it possible? What i know is when you right click the movieclip from the library you can link in to your class. I want to know if i can do it without that method.

For example:

Main.fla - \*\* box1\_mc, box2\_mc, box3\_mc\*\*

MyClass.as - how can i set their alpha from this class? ( **box1\_mc.alpha = 0** , etc)… something like this

I’m new to making a class so any help is appreciated…Thanks
