For something like a turn-based card game, you can model the game with
functions like:
(update state & args) => new-state
I'm not familiar with Samurai Sword, but I have played Bang!, which is
supposedly similar. To model this in a functional language, consider how
you'd describe the state of the game at any instance in time.
At a minimum, players will typically have some life counter and a set of
cards in their hand. So one might imagine the game state to look something
like:
(def state
{:players
{:alice {:life 4, :hand [:bang! :bang! :miss]}
:bob {:life 3, :hand [:bang! :miss :miss]}}}
Now you just need a function that will take the current game state and
return a new state:
(play state :alice :bang! :bob)
=> {:players
{:alice {:life 4, :hand [:bang! :miss]}
:bob {:life 2, :hand [:bang! :miss :miss]}}}
