Flash Catalyst is a standalone tool that makes it easy for non-coding designers to create basic interactivity for their Flash-based projects before handing projects to programmers for integration work – or to complete simple projects without a programmer’s help.
Here's how to create your first project in Flash Catalyst CS5.
Create a mockup in Illustrator for your Flash-based application, then save the file and open Flash Catalyst.
Choose New Project from Design File > From Adobe Illustrator AI File. Catalyst asks you about some options, including how gradients and effects are applied. Click OK to continue.
Now you can start applying behaviours to elements. Right-click on each part individually and select Convert Artwork to Component, picking what it should do from the list of available components.
