Robert,

Thanks for the recommended reading for clean code. I'll check it out.

I have tried your example:

     MasonGeometry geometry = (MasonGeometry)object;
     Indv indv = (Indv)geometry.getUserData();
     int hColor = indv.getHealthStatus();

The Sim gives me the same error:
java.lang.ClassCastException: java.base/java.lang.Integer cannot be cast to disaster.Indv
