General Information
The minerl package includes several environments as follows.
This page describes each of the included environments, provides usage samples,
and describes the exact action and observation space provided by each
environment!
Caution
In the MineRL Competition, many environments are provided for training,
however competition agents will only
be evaluated in MineRLObtainDiamondVectorObf-v0 which has sparse rewards. See `MineRLObtainDiamondVectorObf-v0`_.
Note
All environments offer a default no-op action via env.action_space.no_op()
and a random action via env.action_space.sample().
Environment Handlers
Minecraft is an extremely complex environment which provides players with visual, auditory, and informational observation of many complex data types. Furthermore, players interact with Minecraft using more than just embodied actions: players can craft, build, destroy, smelt, enchant, manage their inventory, and even communicate with other players via a text chat.
To provide a unified interface with which agents can obtain and perform
similar observations and actions as players, we have provided
first-class for support for this multi-modality in the environment:
the observation and action spaces of environments are
gym.spaces.Dict spaces. These observation and action
dictionaries are comprised of individual fields we call handlers.
Note
In the documentation of every environment we provide a listing
of the exact gym.space of the observations returned by and actions expected by the environment’s step function. We are slowly
building documentation for these handlers, and you can click those highlighted with blue for more information!
Basic Environments
Warning
The following basic environments are NOT part of the 2020 MineRL Competition! Feel free to use them for exploration but agents may only be trained on MineRL competition environments!
