[Rails-devel] Tile orientations

[Erik V. <eri...@hc...>]

I have started checking the tile orientations in Tile Designer
vs. the files as provided with the games (1830 only so far).
(the standard is that the position of the tile number defines 
either the S or the SW edge of the unrotated tile).

It turns out that almost all 1830 tiles have a different orientation
in TileDesigner! However statistically unlikely it may be, the only
correct one (except the obvious tile #63) was tile #67!

I have made a new version of the TileDesigner database, which I will
send to Brett for conversion to .gif files. I have also doubled the sizes
of the tile numbers and revenue indicators, hoping that these would get a
bit
closer to being readable. I will change the XML accordingly. 

As said, only 1830 has been done so far. Tile #45 exists in two versions
in this game, I gave chosen one of these as the standard one, 
in line with the choice made in the PS18XX 1830 tile set.

In other games, tiles have been printed in different orientations
(i.e. with the tile number in a different position w.r.t the track).
So we'll have to make the unrotated tile position game-dependent
(it's a pity we can't move the tile number to different positions).

The base rotation per game will be defined in TileSet.xml, 
I think by a <Tile> attribute like  baseRotation="5" 
(the number 5 would apply to e.g. tile 7 in 1856).

The purpose if this all is to keep the orientation indications of laid
tiles,
as printed in the OR and Log screens, in line with those used by PBEM
players.
