Map Games Proto: A Framework for Reinforcement Learning in Games

Map Games Proto is a fork of OpenSpiel, maintained by LogitGames. This package is available on PyPI as map-games-proto.

OpenSpiel is a collection of environments and algorithms for research in general reinforcement learning and search/planning in games. OpenSpiel supports n-player (single- and multi- agent) zero-sum, cooperative and general-sum, one-shot and sequential, strictly turn-taking and simultaneous-move, perfect and imperfect information games, as well as traditional multiagent environments such as (partially- and fully- observable) grid worlds and social dilemmas. OpenSpiel also includes tools to analyze learning dynamics and other common evaluation metrics. Games are represented as procedural extensive-form games, with some natural extensions. The core API and games are implemented in C++ and exposed to Python. Algorithms and tools are written both in C++ and Python.

Installation

Install from PyPI:

pip install map-games-proto

Note: The package is installed as map-games-proto but imported as open_spiel:

import open_spiel

• Make CC analogs of these classes: class DeckStatus(PClass): idx = field(type=int) uuid = field(type=str) faceup_stack = field(type=(FaceupCardStack, type(None)), initial=None) faceup_spread = field(type=(FaceupCardSpread, type(None)), initial=None) facedown_stack = field(type=(FacedownCardStack, type(None)), initial=None) facedown_spread = field(type=(FacedownCardSpread, type(None)), initial=None) discard_faceup_stack = field(type=(FaceupCardStack, type(None)), initial=None) discard_facedown_stack = field(type=(FacedownCardStack, type(None)), initial=None)

The command to run the tests is:

python open_spiel/python/tests/games_interstate_test.py

You can also run specific test methods if you want:

Run just one test

python open_spiel/python/tests/games_interstate_test.py GamesInterstateTest.test_default_parameters

Run with verbose output

python open_spiel/python/tests/games_interstate_test.py --verbose

If you want to run all Python tests in the test suite, you could do:

Run all tests (if you have pytest installed)

pytest open_spiel/python/tests/

Or run all game tests matching a pattern

python -m unittest discover open_spiel/python/tests/ "games_*_test.py"

The test uses absltest which is Google's testing framework, so it can be run directly as a Python script as shown above.

When you encounter a build error like "No rule to make target", follow these steps:

1. Try running make games directly from the build directory: cd /Users/jh/Projects/map_games_proto/build make games
2. This often resolves stale build state issues.
3. If that doesn't work, try a clean rebuild: cd /Users/jh/Projects/map_games_proto/build rm -rf games/CMakeFiles/games.dir/interstate/* make games
4. For more serious issues, do a full clean and reconfigure: cd /Users/jh/Projects/map_games_proto/build rm -rf * cmake ../open_spiel make games
5. Use the build script from the project root: cd /Users/jh/Projects/map_games_proto ./open_spiel/scripts/build_only.sh interstate

Quick Rebuild and Test Commands:

Single command chain: ./open_spiel/scripts/build_only.sh interstate && pip install -e . --no-build-isolation && python open_spiel/python/tests/games_interstate_test.py

Or broken down:

1. Rebuild just the interstate game (fastest C++ build): ./open_spiel/scripts/build_only.sh interstate
2. Update Python bindings (development install): pip install -e . --no-build-isolation
3. Run the test: python open_spiel/python/tests/games_interstate_test.py

Even Faster (if you're iterating):

After the first build, you can often skip the pip install step if you're only changing C++ implementation (not headers or interfaces):

./open_spiel/scripts/build_only.sh interstate && python open_spiel/python/tests/games_interstate_test.py

This typically takes less than 10 seconds for rebuilding just the interstate game and running the tests!

Most Common Commands

./open_spiel/scripts/build_only.sh interstate ./build/examples/console --game=interstate python open_spiel/python/tests/games_interstate_test.py ./open_spiel/scripts/buildpiptest.sh interstate ./open_spiel/scripts/buildtest.sh interstate

TODO:

• Figure out how to enumerate (or assign action indices) to all the ways that someone can claim a path. Maybe it means discrete actions for selecting resources? There needs to be some 1-n translation of web-site actions to granular game actions.
• Figure out "MaxChanceOutcomes" for InterstateGame.
• Finish implementing "DoApplyAction" for the Faceup Spot Actions
