RE: [Repast-interest] RE: Different types of signals

[Nick C. <nic...@ve...>]

I'm not sure I follow what you said below, but the idea here is that all
the agents reside in the world (the Object2DTorus). The ImmuneSpace
handles the dispersion of signalA (or whatever it actually is called).
Agents look in the Immunspace for signal A. To disperse another signal
(signalB), you need to create another space. This could probably be
another instance of an ImmuneSpace. So,

spaceA =3D new ImmuneSpace(diffusionConstant, evapRate, worldXSize,
worldYSize);
spaceB =3D new ImmuneSpace(diffusionConstant, evapRate, worldXSize,
worldYSize);

Use spaceB to disperse the other signal. Agents that disperse signalA
will work with spaceA. Agents that disperse signalB will work with
spaceB. The agent that can detect signalA and signalB will know about
about both spaces and look in each for both types of signals.

hope this is clear,

nick
