Look at Direction.java for clarification, although ISTR there are better commented places which I can not bring to mind. The way the grid is laid out is not something I can comment on with any confidence as it was in place from years before I joined the project. I certainly recall finding it surprising initially, however it clearly works, and knowing nothing much about map projections I am happy to credit the elder developers with knowing what they were doing. Generally I think it is best not to have to think about the map embedding detail, and use abstractions like getSurroundingTiles() that hide that from you. Cheers, Mike Pope
