Hi. I am making available some JavaScript code which helps make dialogs for scripts in After Effects (also Photoshop and Illustrator).
Just a few lines can bring up a dialog; it wraps up some of the ScriptUI functionality for you, for certain kinds of dialogs.
For example,
can be displayed with:
var omd = newOminoDialog("Example Omino Dialog");
omd.number("a number","n",88.21);
omd.string("a string","s","your name here");
var result = omd.run();
Here's a link to further explanation on me blog, including how to read the results of the dialog (it's easy). Hope someone finds it useful! Feel free to contact me with questions &c.
