MTropolis

mTropolis was a multimedia authoring tool debuting in 1995. mTropolis was bought in 1997 by Quark, which moved development from Burlingame, California to Denver and then cancelled the product one year later. [http://archive.salon.com/21st/feature/1998/06/10feature.html]

History

mTropolis (pronounced "metropolis") competed in the interactive multimedia product space dominated in the 1990s by Macromedia Director. The software's maker, mFactory (pronounced "em-factory"), variously positioned mTropolis as an alternative and as an adjunct to Director.

mTropolis was short-lived, being bought by Quark in 1997, who then discontinued the product a few months later, possibly in favor of QuarkImmedia. Many believe though that the use of behaviors in mTropolis spurred Macromedia on to introduce behaviors in Director 6.0.Fact|date=June 2008

While multimedia CD-ROM authoring has largely been rendered irrelevant by online content distribution, mTropolis remains an interesting study in application design, and held a loyal following for many years.Fact|date=June 2008

Paradigm

The development environment was very different from the other tools around at the time - Apple Computer's HyperCard and others had a card based metaphor, and Macromedia Director had a film metaphor (the content area is called The Stage, the time line The Score, an assets library named The Cast, etc). In mTropolis there were sections, subsections, and scenes. Assets would be placed onto the scene, and then combinations of behaviors and modifiers would be dragged onto the assets

Powerful interaction and animation could be created by making different modifiers send messages to each other, allowing a user to create something impressive fairly quickly, without any typing. There was a simple programming language, accessed via a Miniscript modifier, but most of the programming was achieved by attaching standard behaviors and modifiers, and making selections within the modifier pop-up menus.

Technical Issues

According to Starship Titanic author Douglas Adams, his team had originally selected mTropolis 1.0 for its development platform but it had to be abandoned for unspecified technical insufficiencies in favor of an in-house tool. [http://www.starshiptitanic.com/game/mac.html]

Miniscript Limitations

One criticism of the tool was that the integrated programming language, Miniscript, was lacking key features necessary for common tasks. Because mTropolis was conceived around a visual programming metaphor, mFactory engineers intentionally omitted control constructs such as conditional loops. To remedy such limitations, the third-party developer AX Logic produced the commercially-available Alien Studio modifier as a drop-in replacement for Miniscript.

File Format

The advent in version 1.1 of the mTropolis browser plug-in for Netscape Navigator, dubbed "mPire," exposed a core architectural shortcoming. The binary file format was not cross-platform; in order to make a mTropolis element available for embedding on a web page, the author was required to save a Macintosh version and a separate Windows version. Hence the web server had to store redundant copies of the same content, consuming disk space and necessitating the use of loader pages to serve the file appropriate for the end user's operating system.

Macintosh-Only Authoring

While playback engines existed for both the Macintosh and Windows platforms, the mTropolis authoring system itself only ran on the Mac.

Titles Created with mTropolis

A few CD-ROMs were created using mTropolis, including the BAFTA award winning MindGym, Scott Kim's Obsidian, A Sharp's King of Dragon Pass, the Muppets Treasure Island, Voyager's Fun With Architecture and The Magic World of Beatrix Potter.Fact|date=June 2008
