Re: makeProbeAtX$Y - Can I create a custom probe map for an object?

[Paul E Johnson]

Hey, Geoff:

You can control what things appear in a probe. Take a look at the
swarmapps for objective C, in the heatbugs, for example.  Or, I suppose,
look in jheatbugs, to see the same. THat part is pretty easy.

The source code for all swarm is available. Look on the ftp server and
there is a directory "src" and if you are using a newish swarm, it will
be under "testing". Now I'm running:

ftp://ftp.swarm.org/pub/swarm/src/testing/swarm-2002-05-14.tar.gz

I'm sorry to say I don't have more documentation to give about how the
jni works, but I think there are lots of Java books for that.
