Guides to using Flash abound (see Computer Media, LJ 1/02 and LJ 5/1/01), but these two do an exceptional job of highlighting more advanced techniques and helping developers push the boundaries of the software's capabilities. Helping intermediate Flash users learn by example, ActionScript focuses entirely on using Flash's built-in scripting language from a designer's perspective. All exercises and source code are located on a companion web site. For advanced developers, Samurai assumes a solid foundation in ActionScript, as well as additional web languages. Its useful features include "showcase" projects (available on the companion CD-ROM), which demonstrate covered techniques. Topics include 3-D, dynamic Flash, and integrating Flash with XML and JavaScript. Larger libraries should consider both where advanced design titles circulate.
