class SimpleTableTopEnv[source]#

Bases: TableTopEnv

A simple table-top environment that overrides two methods.

  • _reset_scene() is the method to be implemented by the subclass. This function will be called by reset(). This method should return a dictionary of metainfo of the objects in the environment. After the metainfo is returned, the environment will be saved by the WorldSaver.save() method, so that the scene can be restored using restore().
