TextWorld

Build Status PyPI version Documentation Status Join the chat at https://gitter.im/Microsoft/TextWorld

A text-based game generator and extensible sandbox learning environment for training and testing reinforcement learning (RL) agents. Also check out aka.ms/textworld for more info about TextWorld and its creators. Have questions or feedback about TextWorld? Send them to [email protected] or use the Gitter channel listed above.

Installation

TextWorld requires Python 3 and only supports Linux and macOS systems at the moment. For Windows users, docker can be used as a workaround (see Docker section below).

Requirements

TextWorld requires some system libraries for its native components. On a Debian/Ubuntu-based system, these can be installed with

sudo apt update && sudo apt install build-essential libffi-dev python3-dev curl git

And on macOS, with

brew install libffi curl git

Note: We advise our users to use virtual environments to avoid Python packages from different projects to interfere with each other. Popular choices are Conda Environments and Virtualenv

Installing TextWorld

The easiest way to install TextWorld is via pip:

pip install textworld

Or, after cloning the repo, go inside the root folder of the project (i.e. alongside setup.py) and run

pip install .

Visualization

TextWorld comes with some tools to visualize game states. Make sure all dependencies are installed by running

pip install textworld[vis]

Then, you will need to install either the Chrome or Firefox webdriver (depending on which browser you have currently installed). If you have Chrome already installed you can use the following command to install chromedriver

pip install chromedriver_installer

Current visualization tools include: take_screenshot, visualize and show_graph from textworld.render.

Docker

A docker container with the latest TextWorld release is available on DockerHub.

docker pull marccote19/textworld
docker run -p 8888:8888 -it --rm marccote19/textworld

Then, in your browser, navigate to the Jupyter notebook's link displayed in your terminal. The link should look like this

http://127.0.0.1:8888/?token=8d7aaa...e95

Note: See README.md in the docker folder for troubleshooting information.

Usage

Generating a game

TextWorld provides an easy way of generating simple text-based games via the tw-make script. For instance,

tw-make custom --world-size 5 --nb-objects 10 --quest-length 5 --seed 1234 --output tw_games/custom_game.z8

where custom indicates we want to customize the game using the following options: --world-size controls the number of rooms in the world, --nb-objects controls the number of objects that can be interacted with (excluding doors) and --quest-length controls the minimum number of commands that is required to type in order to win the game. Once done, the game custom_game.z8 will be saved in the tw_games/ folder.

Playing a game (terminal)

To play a game, one can use the tw-play script. For instance, the command to play the game generated in the previous section would be

tw-play tw_games/custom_game.z8

Note: Only Z-machine's games (*.z1 through .z8) and Glulx's games (.ulx) are supported.

To visualize the game state while playing, use the --viewer [port] option.

tw-play tw_games/custom_game.z8 --viewer

A new browser tab should open and track your progress in the game.

Playing a game (Python + Gym)

Here's how you can interact with a text-based game from within Python using OpenAI's Gym framework.

import gym
import textworld.gym

# Register a text-based game as a new Gym's environment.
env_id = textworld.gym.register_game("tw_games/custom_game.z8",
                                     max_episode_steps=50)

env = gym.make(env_id)  # Start the environment.

obs, infos = env.reset()  # Start new episode.
env.render()

score, moves, done = 0, 0, False
while not done:
    command = input("> ")
    obs, score, done, infos = env.step(command)
    env.render()
    moves += 1

env.close()
print("moves: {}; score: {}".format(moves, score))

Note: To play text-based games without Gym, see Playing text-based games with TextWorld.ipynb

Documentation

For more information about TextWorld, check the documentation.

Visual Studio Code

You can install the textworld-vscode extension that enables syntax highlighting for editing .twl and .twg TextWorld files.

Notebooks

Check the notebooks provided with the framework to see what you can do with it. You will need the Jupyter Notebook to run them. You can install it with

pip install jupyter

  • game created with GameMaker doesn't understand 'fridge'

    game created with GameMaker doesn't understand 'fridge'

    Hello, I was trying to create a game with the GameMaker. However, when I create a container named either 'fridge' or 'refrigerator' and I record the quest for the game I get the following message: You can't see any such thing. But it actually appears on the quest:

    -= Kitchen =-
You arrive in a kitchen. A typical kind of place. I guess you better just go and
list everything you see here.

You can make out a refrigerator. You bend down to tie your shoe. When you stand
up, you notice a stove. The stove is usual. On the stove you make out a keycard.

    If I leave like that when I run the game to play it that element is replaced with other name such as 'Microsoft box' or 'formless chest':

    -= Kitchen =-
You've entered a kitchen.

You can make out a safe. Hmmm... what else, what else? You make out a closed
formless chest. You can make out a stove. The stove is usual. On the stove you
can make out a cuboid passkey and an American limited edition keycard.

    Do you know what could be causing this problem?

    Thank you in advance,

  • Can we obtain the game map in a data format?

    Can we obtain the game map in a data format?

    Hi, I've found out the --overview and --save-overview option which can generate an image representation of the generated game map with the locations and the inventory/objective. Is there a way to obtain the generated game graph/map? Which contains the different rooms and the connection label between the rooms? For example, Kitchen and a connection west to room..etc. in a text/JSON/graph format etc.. something other than an image..

    Or maybe there is someplace in the repo. from where I can obtain this information? Thanks.

  • Negation of a state in defining a new command

    Negation of a state in defining a new command

    While defining a new command in the logic file, is it possible to mention that certain state cannot be satisfied? For example, I have a game scenario where, you can ask a information to a person. The question can be asked until the person gives the answer. When the person has given the information, you cannot ask the question again. So, I have defined a predicate "asked(pr)", which represents the state when the question has been asked already. And the rule is "ask/pr(pr)" which will be available only when the question was not asked before. So how can I add not "asked(pr)" state in the rule definition?

    Install errors with TextWorld 1.10

    I ran into another build issue installing TextWorld 1.10 (the version pushed to PyPI earlier today).

    To replicate in a clean Conda environment on macOS:

    brew install libffi curl git
conda create --name textworld python=3.7
conda activate textworld
pip install textworld

    This fails with the following error:

  • Hotfix winning conditions

    Hotfix winning conditions

    The win_condition property as part of the generator.game.Game class (found in textworld/generator/game.py) was calling the wrong member variable for the quests. This PR fixes this by calling [Quest].win_events, not [Quest].winning_conditions as it previously was.

    Further, mirrored the win_condition property to create the analogous fail_condition property, if that info is ever needed by the user.

    Lastly, renamed win_condition -> win_conditions and fail_condition -> fail_conditions to more accurately represent their return values, which are a list of conditions (which are in fact, generator.game.Events)

    Note (Sanity Check): winning_conditions isn't a member variable that exists, and only appears in this one file in the whole code base.

    ⏵ grep -r winning_conditions --include=\*.py

    Disable Inform7 debugging commands by default

    This PR makes sure we cannot use the Inform7 testing commands by default. One can enable them by setting the environment variable TEXTWORLD_I6_DEBUG=True.

    This PR adds a modified version of Actions.i6t so we can still get the Inform7 action events that are used for our state tracking.

  • Missing dependency: git

    Missing dependency: git

    In the requirements list for the programs you need to have installed, git is missing. This might be not that obvious untill you try to put a docker container together to run this and fail on the very last part, where it tries to git clone frotz.

    Just as an idea: how about you provide a docker-image already setup with the neccessary requirements such that users can immediately start it?

    Accessing oracle policy commands for tw-cooking games

    Hey,

    I'm unable to access oracle policy commands for tw-cooking games which were introduced a couple of months ago: https://github.com/microsoft/TextWorld/pull/261

    I generated a game with:

    tw-make tw-cooking --recipe 3 --take 3 --cook --cut --open --go 12 --split train --output tw_games/tw-game.z8 --seed 11985

    and tried to play it with:

    tw-play --hint tw_games/tw-game.z8

    but oracle policy commands are not displayed.

    Am I doing something wrong with the game generation or the play command?

  • Using Action-based to create repeatable reward only when the action is executed

    Using Action-based to create repeatable reward only when the action is executed

    Hi @MarcCote we have a follow-up question on issue #296. Is there a way to make the reward repeatable but only occur once with the action? The problem when I tested the "eat apple", "take apple" approach is that the reward keeps occurring as long as the apple is in the inventory (i.e. until "drop apple"). We want the quest to be repeatable so that the agent is rewarded with each time it takes the apple, but only with the action "take". Is there a way to do that?
