Re: [Repast-interest] Moving agents from a grid to another grid

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

Maurilio,

What shows up in a grid is determined by the context associated with that grid. If two grids have the same context, then all the agents in that context should show up in both grids. It sounds like you need two subcontexts -- each with its own grid. The agents would move between those subcontexts and show up in the grids appropriately.
