How to put ActionScript into Catalyst project via Flash Builder?

Question

I don't know if this is the wrong place to put this, but I need to add some ActionScript into my Catalyst project... from what I understand, it can only be done via Flash Builder. Am I right? How?

Hi Alex,
To edit the code of a Flash Catalyst project, you can import it into Flash Builder as follows:
File > Import > Flash Builder Project
Select the FXP file from Catalyst
Make sure "Import new copy of project" is selected, then hit Finish
I'm not sure where you got the ActionScript code that you're planning to use, but it may be difficult to integrate into your project if it's not designed for use with Flex (a lot of AS code snippets you'll find online are just for general use in Flash, not tailored for Flex applications).  But you'll probably want to do something like this:
Locate the image you want to make random.  If you're having trouble doing this, switch the view to Design mode, select the image with the mouse, and then switch back to Code mode to see the corresponding code highlighted.
If there's no id attribute set on the image, add one (so you can refer to it in code later).
If the tag is s:BitmapImage, change it to mx:Image (this is needed to make the contents dynamic)
If the root s:Application tag doesn't have a creationComplete handler, add one (type it partway, then hit Ctrl+Space, then choose "Generate Handler").
In the handler, add your code to randomly select an image filename.
Then set <your image's id>.source = <filename>
Hope that helps!
