I want one animation of a content area but i want the menu to run the animation and put in a certain .swf so i can have something like:
when u click a button that is suposed to goto Home then it plays a MC that has Home as an external .swf loaded into it and when i click another link like Portfolio it starts that MC over but with Portfolio as an external .swf in it
if you want a transition animation between movieclips you can set up the animation movieclip to call the appropriate movie clip to load. this info can be passed to the transition on the button press as well.
in the loadMovie section of flash help there are a bunch of links to loadMovieNum and the movieClipLoader class. plenty of info to get you rollin.
