Returns what additional information should be made available at each game step.
Requested information will be included within the `infos` dictionary
passed to `CustomAgent.act()`. To request specific information, create a
:py:class:`textworld.EnvInfos <textworld.envs.wrappers.filter.EnvInfos>`
and set the appropriate attributes to `True`. The possible choices are:
* `description`: text description of the current room, i.e. output of the `look` command;
* `inventory`: text listing of the player's inventory, i.e. output of the `inventory` command;
* `max_score`: maximum reachable score of the game;
* `objective`: objective of the game described in text;
* `entities`: names of all entities in the game;
* `verbs`: verbs understood by the the game;
* `command_templates`: templates for commands understood by the the game;
* `admissible_commands`: all commands relevant to the current state;
In addition to the standard information, game specific information
can be requested by appending corresponding strings to the `extras`
attribute. For this competition, the possible extras are:
* `'recipe'`: description of the cookbook;
* `'walkthrough'`: one possible solution to the game (not guaranteed to be optimal);
Example:
Here is an example of how to request information and retrieve it.
>>> from textworld import EnvInfos
>>> request_infos = EnvInfos(description=True, inventory=True, extras=["recipe"])
...
>>> env = gym.make(env_id)
>>> ob, infos = env.reset()
>>> print(infos["description"])
>>> print(infos["inventory"])
>>> print(infos["extra.recipe"])
Notes:
The following information *won't* be available at test time:
* 'walkthrough'
