Re: [Swarm-Support] specifying Agent creation/actions through a .scm file

[Paul Johnson]

In Objective-C, I've used .scm files to introduce all kinds of info in a 
simulation.  I recently was reworking the Arborgames model and 
introduced .scm files to store various values, maybe these will give you 
a hint.  I'm not doing this in Java, but doubt that the issue is grossly 
different.

I've done "serialization" with .scm files in other projects.  You can 
have agents save their state to files, and then you can restart the 
entire simulation at that point.  I think I only have 2 more-or-less 
completely functional examples like that:

(That's the model described in Huckfeldt, Johnson, and Sprague, 
Political Disagreement, Cambridge University Press, 2004)

http://ArtStkMkt.sourceforge.net
The most recent version, ASM-2.4, implements serialization in .scm files.

As far as I know, we now can save Swarm lists and Arrays, either shallow 
or deep, and there are also special methods to save C arrays of doubles 
or ints (Opinion model demonstrates)
