[Rails-devel] Terrain XML definitions

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

Hi Martin,
I suggest the following to use for Rails 2.0.

This is the result of a off-list discussion with Martin how to define 
terrain costs for 1846. The game features terrain cost on hex edges.

Stefan

* Define Terrain in Defaults:
<Defaults>
	<Terrain type="mountain" cost="80" />
	<Terrain type="river" cost="40" />
</Defaults>

* Terrain on Hexes:
<Hex name="D8" tile="0"/>
	<Terrain type="mountain"/>
</Hex>

* Terrain on Edges:
<Edge from="D8" to="E9">
	<Terrain type="river" />
</Edge>

* This also allows moving the impassable definitions from Hexes to Edges:

<Edge from="D8" to="E9">
	<Impassable />
</Edge>

The immediate advantage is that this avoids answering the question if 
double-definitions are required and (if not) what happens if there is a 
double-definition.

Remark: From and to have no effect here, but there might be other 
occasions there this might be helpful in the future.
