ExtendScript (.jsx) used to animate Adobe Illustrator’s layers in order to preview sequenced layer frames for animation.

Here’s a close-up of the script’s dialog window:

1. Animates layers based on user-defined frame rate.
2. Skips non-printable (template) layers.
3. Ascending or descending layer animation.
4. Automatic direction reversal (ping pong).
5. Restores layer visibility when done.

Put Layer Animation ⭐⭐⭐⭐⭐.jsx in /Applications/Adobe\ Illustrator\ CC\ 2014/Presets.localized/en_US/Scripts and run it directly in Illustrator via the File > Scripts menu.

There’s a couple of ways to develop/test this script:

1. See installation instructions above (not recommended).
2. Use Adobe’s free ExtendScript Toolkit (ESTK) app (see animated gif below).

1. Using a dialog window, from what I have discovered, there’s no way to let the user cancel a loop (tried this, didn’t work).
2. Related to the above, the built-in method $.sleep() blocks all other scripts from executing; that means spinning beach ball hell.
3. Once a palette displays it will break its connection with the Application; this limits the kind of interactivity a palette UI offers.
