   .. py:method:: __del__()

      Close the environment.



   .. py:method:: reset()

      Reset the environment to its initial state.



   .. py:method:: step(action)

      Step the environment applying the provided action.



   .. py:method:: render(mode=None)

      Render the environment.



.. py:class:: LunarLander(name = None, frameskip = 1, episodic_life = True, autoreset = True, wrappers = None, delay_setup = False, deterministic = False, continuous = False, render_mode = 'rgb_array', remove_time_limit=None, **kwargs)

   Bases: :py:obj:`plangym.core.PlangymEnv`


   Fast LunarLander that follows the plangym API.


   .. py:attribute:: _deterministic


   .. py:attribute:: _continuous


   .. py:property:: deterministic
      :type: bool

      Return true if the LunarLander simulation is deterministic.


   .. py:property:: continuous
      :type: bool

      Return true if the LunarLander agent takes continuous actions as input.


   .. py:method:: init_gym_env()

      Initialize the target :class:`gym.Env` instance.



   .. py:method:: get_state()

      Recover the internal state of the simulation.

      An state must completely describe the Environment at a given moment.



   .. py:method:: set_state(state)

      Set the internal state of the simulation.

      :param state: Target state to be set in the environment.

      :returns: None



   .. py:method:: get_image()

      Return a numpy array containing the rendered view of the environment.

      Square matrices are interpreted as a greyscale image. Three-dimensional arrays
      are interpreted as RGB images with channels (Height, Width, RGB).



   .. py:method:: process_terminal(terminal, obs=None, **kwargs)

      Return the terminal condition considering the lunar lander state.
