Are you sure you're implementing it correctly? You have to assign the class to your library item and it should work. If you're just arbitrarily attaching a MovieClip from the library without assigning that symbol the class, it will give you that error.

If you want to typecast your movieclip, I think you need to do : var mc:MovieClip = myClip.attachMovie(linkage, name, depth).init(args); var myClass:MyClass = MyClass(mc); myClass.init(args); BLITZ | Patrick Matte - 310-551-0200 x214 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Ngo Sent: Wednesday, May 02, 2007 6:17 PM To: flashcoders@chattyfig.figleaf.com Subject: RE: [Flashcoders] AS2: generating new instances dynamically? Another way to do this is to have an init() method that you call in-line to your attachMovie(). class MyClass extends MovieClip { public function MyClass() {} public function init(args):MyClass { // do your constructor type stuff here return this } } And this is how you use it: var myClass:MyClass = myClip.attachMovie(linkage, name, depth).init(args); This way, you can also type-cast your instance to your Class without having to re-cast. I forgot who came up with this or where I saw it, but it's been pretty useful for me when extending MovieClip. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alain Rousseau Sent: Wednesday, May 02, 2007 9:08 PM To: flashcoders@chattyfig.figleaf.com Subject: Re: [Flashcoders] AS2: generating new instances dynamically? Hi Sebastian, When extending the MovieClip Class in AS2, there is no way to access the constructor. All initializations should be done, like Matthias Dittgen mentionned with the optional initObject argument of attachMovie(libraryID, instanceName, depth, initObject) That way you set all the properties that you need before the onLoad() of your Class. Don't forget that it's a MovieClip and in AS2 it's instances are not handled the same way as other Classes and has it's own rules :) You should read on the MovieClip Class, it's all there HTH Alain sebastian chedal wrote: >> If it is a movie clip you want to instantiate then you have to use: >> _root.attachMovie(libraryID, instanceName, depth); > >> The class associated with it will construct and the onLoad event will >> trigger if it is being listened to. > > this indeed works, but then i can't pass any values to the constructor. > Is there any way to attachMovie and at the same time pass values to it? > > I supose I can always refer to it afterwards on the time line and call a > custom function... but it would be nice to use the constructor's > functionality. > > I had hoped I could generate new instances just by calling a constructor > instead of attaching it to something; but i guess logically i it needs > to be > attached to be "on the timeline".
