I've been thinking about the basic tasks:
- Rules for mapping cursor position onto cell coordinates
- Rules for mapping cell coordinates to cursor position
- Create the IsometricGrid class
- Modify GridFactory to allow access of the IsometricGrid class
- Modify the MapPropertiesDialog class and xml to allow the selection of the new map type
- Modify SightType so that vision areas are ellipses and rectangles rather than circles and squares
- Modify Light so that vision areas are ellipses and rectangles rather than circles and squares
- Modify Zone.TOKEN_Z_ORDER_COMPARATOR to order tokens by isometric depth rather than an arbitrary Z value
- Modify ZonePoint getNearestVertex. Seems like this should inherit for Grid class, not sure why it doesn't. Existing code doesn't look like it would work well for hexes?
- Think about how best to position the different tokens types on the isometric cell
If you want to have a play with what I have done so far, you can pull my "Isometric" branch from my Github repository (https://github.com/Jaggeroth/maptool)
Obviously there is still a lot to do before this would be of much benefit. It might even be necessary to create a new Token Type. Anyway, I am finding this a fun little project for someone that has written in java for years but has never ever touched Swing!
