Exactly Nick, the question is how can we get the getDirection on those Agents which are from another class in nested neighbourhoods. It is not straight forward like routine java for example saying: SAgent.getDirection on those Agents. It doesn't accept it.
Cheers,
Zahrieh

I think this is because you are calling this.getDirection which returns the direction of the agent whose step method is currently being called. If you want the direction of the agents in the cells, you'll have to call getDirection on those. Perhaps I'm missing something here though.
