I don't know what do you mean. But you can make an animated icon or whatever by writing a special method. Press Ctrl+Shift+F "animatedSprite" on the script window, and copy one of the instances of that method. You can use that as a reference. Se the notes.html for more information about using the arguments of that method. You must specify: the height and width of the frames, and the rows and columns of the animation.
BTW: I'm not too good writing in english.
