  - We use the self._action_to_direction to convert the discrete action (e.g., 2) to a grid direction with our agent location. To prevent the agent from going out of bounds of the grid, we clip the agent's location to stay within bounds.
  - We compute the agent's reward by checking if the agent's current position is equal to the target's location.
- - Since the environment doesn't truncate internally (we can apply a time limit wrapper to the environment during :meth:make), we permanently set truncated to False.

  - We once again use _get_obs and _get_info to obtain the agent's observation and auxiliary information.
