Need help to check MC for attached movie

Hey there!
I’m kind’a curious about this one. I have this flash timeline with an empty movieclip in it. And i have some button that attaches an ‘actionscript-exported’ movieClip from the library… like this:

someBTN.onRelease = function(){
NAV_MC.attachMovie(“some_mc”,“some_instancename”,1);
}

Now…each time i press that button, the ‘some_mc’ loads. Is there some clever way of checking if the movieclip has already loaded, so that it doesn’t load if it’s already loaded…did that make any sense?

I know you can do it, if the movieclip you load, is a external .swf. something like…
someBTN.onRelease = function(){
if(_root.NAV_MC==external_mc.swf, true){
}else{
// some action
}
}

Can you do this with attached MC’s?

Any help is appreciated :slight_smile:

cheers, mikz
