Dominion object model

This package contains two abstract base classes for implementing players and client libraries for the dominion project.

You can implement a GUI client for humans to play the game or an AI computer player.

Usage

A dominion player must implement the Player interface. The dominion game engine will keep a reference to the player object and call its methods at the right time.

class Player(metaclass=ABCMeta):
    @abstractmethod
    def play(self):
        pass

    @abstractmethod
    def respond(self, action, *args):
        pass

    @abstractmethod
    def on_game_event(self, event):
        pass

    @abstractmethod
    def on_state_change(self, state):
        pass

A client library will implement the GameClient interface and a reference to it will be passed to concrete player implementations. When the concrete player who implements the Player interface receives the play() command from the game engine it will invoke various GameClient methods until it finally calls done() and their turn ends.

class GameClient(metaclass=ABCMeta):
    @abstractmethod
    def play_action_card(self, card_type: str):
        pass

    @abstractmethod
    def buy(self, card_type: str):
        pass

    @abstractmethod
    def done(self):
        pass

Examples

The dominion project itself contains several computer players.

The dominion-pygame project is an implementation of a GUI client that lets humans play against each other and or bots.

Build and publish

This section is for the Dominion developers. If you just want to implement a player or a client library you can stop reading.

Pre-requisites

• Install pyenv or pyenv-win
• Install poetry

Create a Python 3.8.2 environment

$ pyenv install 3.8.2
$ pyenv local
$ poetry init
$ poetry env use 3.8.2
$ poetry install

Building the package

Here is the command to build the package:

(🐙)/dominion-object-model
$ poetry run python setup.py bdist_wheel

The result is tar-gzipped file in the dist subdirectory:

(🐙)/dominion-object-model
$ ls dist
dominion_object_model-1.0.1-py3-none-any.whl

Save the following to ~/.pypirc

[distutils]
index-servers=
    pypi
    pypitest

[pypitest]
repository = https://test.pypi.org/legacy/
username = <your user name>

[pypi]
repository = https://pypi.org/legacy/
username = <your user name>

Next, we can upload the package using twine to PyPI.

(🐙)/dominion-object-model
$ poetry run twine upload -p <redacted> dist/*.whl
