Robert Zubeck 59086147e6 A signed 64-bit integer can be stored as two 32-bit integers in Actionscript, but converting
them to a single number becomes inconvenient for values larger than an single int, and tricky 
when the value is negative (i.e. in two's complement split into two words, with sign bit only
in the high int). 

Instead of splitting a long into two ints, we store it internally as a byte array that corresponds 
exactly to Java's serialized version (sequence of eight bytes, high byte first), and we provide 
accessors to convert to and from Actionscript numbers. This makes Java Long values readable in 
Actionscript, and vice versa.

Unfortunately, Actionscript does not have a native 64-bit integer - the closest equivalent is the 
Number class. Since this is a double float with a 52-bit mantissa, very large long values will 
suffer precision loss during conversion.

The Narya library
-----------------

The Narya library provides various facilities for making networked
multiplayer games. It's various packages include:

  * geom, util, io - basic tools for doing networked I/O, data structure
    manipulation and some geometry math
  * resource - tools for bundling, deploying and managing media (images,
    sounds, etc.) with a game
  * media - a framework for doing "active" rendering in Java
  * media.image - tools for loading, caching, manipulating and displaying images
  * media.sound - tools for loading, caching, and playing audio
  * media.animation, media.sprite - works in concert with the active
    rendering system and provides tools for defining and manipulating
    sprites (graphical entities that follow paths) and animations
    (graphical entities that affect the display in other ways)
  * miso - a framework for defining and displaying isometrically rendered scenes
  * presents - a framework for distributing information among a server and
    networked clients
  * crowd - builds on the presents framework to create the notion of
    bodies and rooms and provides chat infrastructure
  * whirled - builds on the crowd framework and defines a scene graph with
    portals to move between scenes and provides hooks for distributing and
    updating scene data (for example isometric rendering information) over
    the network
  * cast - a framework for defining and using recolorable, composited
    characters with different poses and actions
  * parlor - builds upon the crowd framework to create the notion of a
    game with players and provides tools for making turn based games
  * puzzle - builds on the parlor and media frameworks to provide tools
    for implementing puzzle games in a networked environment
  * micasa - builds on the parlor framework to provide lobbies and
    matchmaking for multiplayer games 

Documentation is somewhat sparse at the moment, but inspection of the code
in the tests/ directory shows examples of use of many features of the
library.

Building
--------

Building the library is very simple. First ensure that the necessary third
party jar files are available either in the lib/ directory or in the
system wide jar file location specified in build.xml. See lib/README for a
list of the necessary third party jar files and how to get them.

The library is built using ant, a modern build tool available from The
Jakarta Project. If you aren't already using ant for other projects, it
can be found here:

  http://jakarta.apache.org/ant/

Invoke ant with any of the following targets:

  all: builds the distribution files and javadoc documentation
  compile: builds only the class files (dist/classes)
  javadoc: builds only the javadoc documentation (dist/docs)
  dist: builds the distribution jar files (dist/*.jar)

Distribution
------------

The Narya library is released under the LGPL. The most recent version of
the library is available here:

  http://www.threerings.net/code/narya/

Contribution
------------

Contributions to Narya are welcome. Control of the CVS repository is
presently in the hands of mdb@threerings.net, who should be emailed about
submissions. Soon we will be migrating to Subversion and making the
repository publicly accessible. For now, source releases are available at
the above website.

Contact Information
-------------------

Narya is actively developed by the scurvy dogs at Three Rings Design,
Inc. Contact Michael Bayne <mdb@threerings.net> with questions, comments
and other wordly endeavors.
