"I continue to develop Dr Nicâ??s Civilizations game. This lead me to
develop a DSL for the specification of game rules. You need to see this.
"Hereâ??s an example definition of some terrain:
class Desert < Terrain
title “Desert”
letter “d”
graphic “desert”
movement_cost 1
defense_bonus 10
food 0
shield 1
trade 0
end
class Oasis < Desert
title “Oasis”
special_code 1
food 3
shield 1
trade 0
graphic “oasis”
end
“An Oasis is a special version of the Desert terrain, so Ruby subclasses
offer a compatible relationship.”
I’ve written up why I used a Ruby DSL for this static configuration, and
how it is implemented here:
