Class Sewers

java.lang.Object
game.Sewers
public class Sewers extends Object
A sewer through which a sewer diver can move: a grid of Tile objects with a weighted graph of all non-floor tiles.

There is an entrance to the sewer system and a ring location (which may also be the entrance).

  • Method Details

    • digExploreSewer

      public static Sewers digExploreSewer(int r, int c, Random rand)
      Return a new random sewer system with r rows, c columns, and no coins, all edges have weight 1, and there is a ring a reasonable distance from the exit. rand is the source of randomness for the sewer-system generation.

    • digGetOutSewer

      public static Sewers digGetOutSewer(int r, int c, int currentRow, int currentCol, Random rand)
      Return a new random sewer system with r rows, c columns, and random coins and edge weights. It is guaranteed that (currentRow, {currentCol) will be an open floor cell. rand is the source of randomness to use for the sewer-system generation.

    • numOpenTiles

      public int numOpenTiles()
      Return the number of open floor tiles in this sewer system (this is the size of the graph).

    • rowCount

      public int rowCount()
      Return the number of rows in the grid.

    • columnCount

      public int columnCount()
      Return the number of columns in the grid.

    • graph

      public Set<Node> graph()
      Return the set of all nodes in the graph. This is an umodifiable view of the graph.

    • entrance

      public Node entrance()
      Return the node corresponding to the entrance to the sewer system.

    • ring

      public Node ring()
      Return the ring node in this sewer system.

    • tileAt

      public Tile tileAt(int r, int c)
      Return the Tile information for tile (r, c). Requires: (r, c) must be in the grid.

    • nodeAt

      public Node nodeAt(int r, int c)
      Return the node at the given (r, c). Requires: (r, c) must be in the grid.

    • serialize

      public List<String> serialize()
      Serialize this sewer system to a list of strings that can be written out to a file. The list of strings can be converted back into a Sewers using deserialize().

    • deserialize

      public static Sewers deserialize(List<String> nodeStrList)
      Convert nodeStrList, which was output by serialize(), back into a Sewers. Requires: The list of strings is of the format output by serialize().
