public class PolycraftComponent extends DiarcComponent

  • Constructor Details

    • PolycraftComponent

      public PolycraftComponent()

  • Method Details

    • parseArgs

      protected void parseArgs(org.apache.commons.cli.CommandLine cmdLine)
      Description copied from class: DiarcComponent
      Called directly after construction to pass runtime values that will override default values. This should parse all the options that additionalUsageInfo provides.zs
      Overrides:
      parseArgs in class DiarcComponent

    • additionalUsageInfo

      protected List<org.apache.commons.cli.Option> additionalUsageInfo()
      Description copied from class: DiarcComponent
      Command line options available in sub-class. This should be paired with a parseArgs implementation.
      Overrides:
      additionalUsageInfo in class DiarcComponent
      Returns:

    • init

      protected void init()
      Description copied from class: DiarcComponent
      Perform any component initialization. This should not be used for setting local fields to default values as was the case in DIARC. This method is called after the constructor, and after parseArgs. Setting default values should be done in field declaration or in the constructor.
      Overrides:
      init in class DiarcComponent

    • initializeBeliefs

      public Set<Term> initializeBeliefs()
      This initializes the map and belief based on the initial state of the game. Also detects and returns a set of detected pre-game novelties.
      Returns:

    • senseNewMap

      public void senseNewMap()

    • observeDiscrepancies

      public List<Map<Variable,Symbol>> observeDiscrepancies(Term state)
      Checks for inventory novelties and at(object,x,y) novelties in agent's local area.
      Returns:

    • isInCurrentRoom

      public boolean isInCurrentRoom(Predicate location)
      Convenience method to filterPointsNotInCurrentRoom when only a single location needs to be checked. Location predicate needs to be of form: at(O,locX,locY)
      Parameters:
      location -
      Returns:

    • filterPointsNotInCurrentRoom

      public Set<Predicate> filterPointsNotInCurrentRoom(Set<Predicate> locations)
      Helper method to filter out locations that are not in the same room as our agent. Useful for checking for at() discrepancies, since our agent can't observe outside its current room. Location predicates needs to be of form: at(O,locX,locY)
      Parameters:
      locations -
      Returns:

    • reportNovelties

      public void reportNovelties(Set<? extends Term> novelties)
      Main entry point for reporting novelties to Polycraft. This checks if the novelty has already been reported, gets the novelty level, reports new unreported novelties to Polycraft, and updates Belief of any reported novelties.
      Parameters:
      novelties -
