I have set up a library project that contains a lot of AS3 util classes that I use in nearly every project. When I start a new build now I include the lib using the library path tab and all is good.
If at the end of the project I need to give my source code to the client how can I package it up so that it will not fail looking for my external libs? Do I just have to package up my class library as well and hand that over too?
i believe you would do a "export release built" and it would take care of that for you or you can just hand over the entire project to your client.. if he wants the actual source code.
Yes, you can just export the project as a release build. You can merge the library into the *.swf compiled project or also distribute using RSL, this way your *.swc library project will be available as a resource in the bin-release folder.
