[Rails-devel] Map.xml - Tile Orientation

[Scott P. <sc...@re...>]

I am modifying the 1830 xml files to put my prototype game into rails (and
having a great time of it!), but have hit a snag.  The map looks right, but
I am running into problems when I try to lay tiles--lots of "no valid
orientation" errors.

My game has the NS tile orientation unlike the EW orientation in 1830.
Things seem to play okay if I leave the orientation as EW in Map.xml
although the map is rotated and the orientations of the special tiles are
wrong.

Instead of the first line of the 1830 Map.xml, I am using the one from 18AL
which has the NS tile orientation.
<Map mapClass="rails.ui.swing.hexmap.NSHexMap" tileOrientation="NS"
letterOrientation="vertical" even="A">

What do the last two items in that line mean ("letterOrientation" and
"even").  Or maybe more helpful for me--what is the short list of things to
change when moving from the 1830 EW tile orientation to the NS orientation?
Thanks.
