That’s really quite helpful and solid. Thanks, Zack!

Thanks to share this source! It saves me!

Nice! I extended it with EmbedSWFLibrary. Especially useful for single-file haXe apps.

How come your site is redirected from ErinGipson.com?

I used to host her site until she took it down. I guess her domain still points to my server.

Kinda interesting though. I’ll have to look into it.

[…] thanks to Zack Jordan for sharing his SWFLibrary […]

thanks for the great ideas, I’ve been scouring the web and blogs for Flex game development ideas - thanks again!

Amazing! Thank you!

I’ve been looking for this functionality for years. Up to this point I’ve relied on a hacky solution that required artists to add 2 lines of code to all their FLAs that retrieved the symbol.

Now maybe someone can explain why Adobe buried this critical functionality 3 levels deep in Loader.loaderInfo.applicationDomain.getDefinition()

No problem. Actually, I’ve got a v2.2 that I’m about ready to release. If you want to use this for a project, I’ll send it to you to test-drive.
