Re: [Rails-devel] Tile and Token Lay GUI Hints

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

Pending answers to the below questions, I have committed code that does the
following:
- In cases where a company has a defined home city, other companies are
prevented to lay tokens if there is no extra free space (be it never, as in
1830 Boston/Baltimore, or temporarily, as in yellow/green 1830 NE New York).
- In cases where a company must choose its home city, other companies are
prevented to lay any tokens until that home token has been laid. This
applies to 1830 Erie and 1835 BA.
- A special provision was needed for green 1835 Berlin, where the one free
token slot can be used even if PR has not yet started.

If I have overlooked other special cases, please let me know.

For now, these checks only apply during post-action validation. Once
Stefan's new route awareness feature is applied to the back-end code, these
checks can also be applied pre-action to prevent untokenable hexes to be
highlighted.

Erik.

>Ultimately the list of allowed locations will have to be prepared in
OperatingRound and put into the LayTile/LayBaseToken actions (which are
already prepared to contain such lists). Doing that will also make it easier
to avoid disallowed lays, such as a NYNH token on Boston in 1830. Such
checks don't yet exist (even in post-laying action validation), and are on
my list to be implemented soon. 

On this matter: I have recently implemented the blocking of token lays on
Mannheim/Ludwigshafen (1835) if BA has not yet laid its home token on that
hex. As a similar rule also applies to 1830 Erie, I think I will create a
generic option that can be set in the XML. 

My question is: does this rule apply to all similar cases, i.e. where an
OO-style two-city hex has a yet unspecified home base? The only other case
I'm currently aware of is 1856 Hamilton, the home base of THB. The 1856
rules and all rule clarifications I have found are silent on this matter,
i.e. on the question if another company may lay a token there before the THB
does. So I would think that it is allowed in this case.

Also, am I right in concluding that in none of the cases mentioned other
companies are prohibited to lay the first *tile* on such a hex?
