Re: [Flashcoders] instantiate symbol linked to parent movie's library
Hi, I don't remember the exact details, but if I remember correctly there are 2 ways: 1. let the child attach the clip at the root, copy its bitmap data and use that to create a clip in its own root, but this will result in static bitmaps only 2. -declare an empty clip with linkage id in the root and export it for runtime sharing -in the child import the clip from the parent for runtime sharing It was one of those hacks, but it's been a long time, so I'm not sure I got the steps all right, I might have those files somewhere.

Re: [Flashcoders] instantiate symbol linked to parent movie's library
Or, maybe I could call a function in the root that would instantiate the symbol, passing the target clip? I'll post my resutls.

Re: [Flashcoders] instantiate symbol linked to parent movie's library
Hi, calling a function in the root that would instantiate the symbol is not going to work, neither is using reflection to get classes by name. The issue you are dealing with is that by default flash will only let you attach clips to a clip from the library from whence it came. I'll try to whip up a sample up of the runtime share hack. greetz JC On Tue, Sep 22, 2009 at 2:08 PM, jonathan howe jonathangh...@gmail.comwrote: Totally forget in AS2, but maybe research getDefinitionByName() - it can retrieve a class based on a classname string - and maybe there are some comments about AS2 vs. AS3 -jonathan On Tue, Sep 22, 2009 at 2:54 AM, Hans Wichman j.c.wich...@objectpainters.com wrote: Hi, I don't remember the exact details, but if I remember correctly there are 2 ways: 1. let the child attach the clip at the root, copy its bitmap data and use that to create a clip in its own root, but this will result in static bitmaps only 2. -declare an empty clip with linkage id in the root and export it for runtime sharing -in the child import the clip from the parent for runtime sharing It was one of those hacks, but it's been a long time, so I'm not sure I got the steps all right, I might have those files somewhere.

Re: [Flashcoders] instantiate symbol linked to parent movie's library
Hi Andrew, i've put a sample together at: http://www.objectpainters.com/downloads/runtimesharinghack.zip user/pass is blog/blog There are 2 demos, the first of how you probably do it at the moment, you load a sub into main and try to attach a clip from main to sub. The sample shows that doesnt work by default. The second sample added a couple of things: -main exports a hack_clip at main.swf for runtime sharing. -sub imports a hack_clip from main.swf for runtime sharing AND puts it on the stage. If you run the 2nd example you see there is no problem attaching a clip from main to sub, even though the attached clip had nothing to do with runtime sharing, only the hack_clip did. In practice you need to account for a couple things: - runtime library sharing is not without it's own problems, but since you can be sure main.swf is already in the cache by the time sub.swf requires it, you're on the safe side - i've never ever used this hack in a real project, so there is some risk involved in using it (but ain't it spiffy ;)). regards, JC On Tue, Sep 22, 2009 at 7:43 PM, Hans Wichman j.c.wich...@objectpainters.com wrote: Hi, calling a function in the root that would instantiate the symbol is not going to work, neither is using reflection to get classes by name.

Re: [Flashcoders] instantiate symbol linked to parent movie's library
Thanks Hans. Yes, I tried this myself this morning. I'm working in AS2. I'm pretty much ruling this out. I think it will be more trouble than it's worth. A little background will clarify why: Our goal was to allow an instructor to create content and then export that content in a single swf file. We'd use swfmill + mtasc to create the swf from within our content-creator application. They'd then be able to upload that swf to any LMS. The presentation engine and the other secure operations would reside in a static swf that would reside in on our server. Just a pipe dream. I'm ready to move on to more viable solutions.

Re: [Flashcoders] instantiate symbol linked to parent movie's library
That's super cool. So the sub only has to have a _single_ library item from the shared library in order to have access to the whole library. That's not very intuitive, but I'm really glad it works!

Re: [Flashcoders] instantiate symbol linked to parent movie's library
Hi Andrew, yes only a single library item. Still before basing a large scale email application on something like this would not make me sleep well at night, unless there wasn't another way. Seeing the large numbers of elearning apps already written in flash, there probably is another way;). From what you describe, maybe you could use: - a template that's loaded by the main engine which loads xml and does things based on that (instead of generating it statically to an swf using swfmill, you'd have different templates). - non library based assets, completely drawn in actionscript, that way recompiling them into the main after changing, would change them for all the subs even if they were compiled with another version of the actionscript asset another time - use the bitmap based approach earlier - an asset swf that gets loaded by each sub swf only once and is used as a container to attach the assets from it's own library to as well One thing I would do is check whether this still works like this in as3 for example. On the other hand if it works it works and if you're under a lot of time pressure this might just be what you need ;) take care Hans On Tue, Sep 22, 2009 at 8:47 PM, Andrew Sinning and...@learningware.comwrote: That's super cool.
