data Action Source #

Cartpole can only go left or right has an action space of "discrete 2" containing {0..n-1}.

FIXME: Migrate this to either a more generic "directions" actions (would need things like "up", "down" versions as well) or a "discrete actions" version. I'm a fan of the former.

GoLeft
GoRight
