How can I generate FLI or FLC format animations?
See the Allegro.cc homepage (http://www.allegro.cc/) for some utilities, for example DTA and Smacker. Also, you can use ASE (Allegro Sprite Editor, http://ase.sourceforge.net/), which allows drawing/editing each frame of the animation and save it as a FLI. Or you can use The GIMP (http://www.gimp.org/) along with it's GFli plugin, using layers as frames, and saving your work as file.fli. The GIMP allows you to edit existent FLI files too.
