Action Spaces

Every MOOG Environment has an action space. This action space is given to the environment's constructor, and must satisfy the API of AbstractActionSpace.

In this directory are a few example action spaces for common interfaces. In particular, it contains:

Grid. This is an [up, down, left, right, donothing] action space commonly used for grid-world environments.
Joystick. This is a continuous 2-dimensional ([0, 1] x [0, 1]) joystick action space, commonly used to impart a continuous force (or velocity) to move an agent.
SetPosition. This is a continuous 2-dimensional ([0, 1] x [0, 1]) action space that sets the position of a sprite. It can be used to simulate a touch-screen interface (e.g. by controlling the position of a perhaps transparent sprite that serves as a finger).
Composite. This provides a way to compose action spaces for multiple interfaces or multiple agents. For example, if your experiment involves joystick motion and eye-tracking, you could have a composite action space with a Joystick and a SetPosition component, where the SetPosition controls a transparent sprite that serves as a marker of eye position and the Joystick controls an agent avatar.
