flash extensions [Solved]

Does anyone know how to create and package flash extensions? Or a good tutorial on how to anyway. I have looked but can’t see anything on the subject.

I have downloaded a few that i use, like flashwhip that converts all selected frames to a symbol. But i want to know how they are made.
Not that i am making one, just interested in how it’s done so i can if i want to in the future. I assume they are made using actionscript but have no idea how to make them work as part of flash.

Any help would be great :D

You can interract with Flash using some scripting languages. We managed it in my work as we needed to create a auto-update/re-publish for all files. It is not easy though and the flash API is not really nice to use. We were using CS3 and found a few issues (e.g. CS3 will randomly crash if opening multiple files too quickly, and it does not report the error back to the API!). This meant we needed a re-publish and a continue re-publish script. Very annoying. Anyway I digress. If you want to create scripts for flash it is possible but not easy. This is an experienced level task and not a beginner.

thanks for the reply, but that’s not quite what i was getting at. I don’t want to change flash itself, i want to know how to create and package .mxp files. They are addons that can be made for all adobe products i believe.

But i have since found that they are made using XML. The documentation i found can be viewed here http://help.adobe.com/en_US/ExtensionManager/2.0/mxi_file_format.pdf if anyone else is interested.
