Class Column

java.lang.Object
net.minecraft.world.level.levelgen.Column
Direct Known Subclasses:
Column.Line, Column.Range, Column.Ray
public abstract class Column extends Object
A representation of an integer valued interval, either bounded or unbounded. While the class itself does not imply any coordinate in particular, this is practically used to represent a column in the Y direction.

  • Method Details

    • around

      public static Column.Range around(int floor, int ceiling)
      Returns:
      A column of the closed interval [floor, ceiling].

    • inside

      public static Column.Range inside(int floor, int ceiling)
      Returns:
      A column of the open interval (floor, ceiling).

    • below

      public static Column below(int ceiling)
      Returns:
      A column of the unbounded interval (-infinity, ceiling).

    • fromHighest

      public static Column fromHighest(int ceiling)
      Returns:
      A column of the unbounded interval (-infinity, ceiling].

    • above

      public static Column above(int floor)
      Returns:
      A column of the unbounded interval (floor, infinity).

    • fromLowest

      public static Column fromLowest(int floor)
      Returns:

    • withFloor

      public Column withFloor(OptionalInt floor)

    • withCeiling

      public Column withCeiling(OptionalInt ceiling)

    • scan

      public static Optional<Column> scan(LevelSimulatedReader level, BlockPos pos, int maxDistance, Predicate<BlockState> columnPredicate, Predicate<BlockState> tipPredicate)
      Scans for a column of states satisfying columnPredicate, up to a length of maxDistance from the origin, and ending with a state which satisfies tipPredicate.
      Returns:
      A column representing the tips found. The column will be bounded if a tip was reached in the given direction, unbounded otherwise.

    • scanDirection

      private static OptionalInt scanDirection(LevelSimulatedReader level, int maxDistance, Predicate<BlockState> columnPredicate, Predicate<BlockState> tipPredicate, BlockPos.MutableBlockPos mutablePos, int startY, Direction direction)
      Scans for a sequence of states in a given direction, up to a length of maxDistance which satisfy columnPredicate, and ending with a state which satisfies tipPredicate.
      Returns:
      The y position of the tip, if found.
