There
are many ways to create Flash animations in Illustrator. One of
the easiest is to place each animation frame on a separate Illustrator
layer, and select the AI Layers To SWF Frames option when you export
the artwork.
Create the artwork you want to animate. Use symbols
to reduce the file size of the animation and simplify your work.
Create a separate layer for each frame in the animation.
You can do this by pasting the base artwork into a new
layer and then editing the artwork. Or, you can use the Release
To Layers command to automatically generate layers consisting of
objects that build up cumulatively.
Make sure the layers are in the order in which you want
to display them as animation frames.
Do one of the following:
Choose File > Export, choose
Flash (SWF) for the format, and click Export. In the SWF
Options dialog box, select AI Layers To SWF Frames for Export As.
Set additional animation options, and click OK.
Choose File > Save For Web & Devices.
Choose SWF from the Optimized File Format menu. From the Type Of
Export menu, choose AI Layers To SWF Frames. Set additional options,
and click Save.
