Re: [Rails-devel] 18EU game option: unlimited plain track

[Stefan F. <ste...@we...>]

Bill & Erik:
just a short comment on the implementation:

As you know all options are duplicated in both the central GamesList.xml as in 
the game-specific Game.xml. 

However the default attribute of the GameOption element in Game.xml has a 
different effect for Rails than the default attribute for the Option element 
in GamesList.xml.

A) Default of Option in GamesList.xml
This is the default value suggested to use if a new game gets started.
A saved game always saves the concrete setting of each option regardless if 
this is the default or not.
This value will never effect loaded games.

B) Default of GameOption in Game.xml:
This is default value is ONLY used for loaded games that do not have the value
defined as the option was previously unimplemented for that specific game.
So a better name for this attribute would be undefined. Even better would be 
merging the two option elements and keep default and undefined attributes 
aside.

A rule of thumb if one introduces new values is simply setting the default in 
GamesList.xml to the value best suited for that game and the default in 
Game.xml to that value that existing games had been used implicitly. 

As both games with a changed option (1826 and 1851) had that option defined 
before it does not matter, as the save files will keep their selected option 
and will not change without players being aware.
