  • Method Details

    • getResult

      @NotNull public @NotNull TreePathResult getResult()
      Description copied from interface: IPathJob
      Get the path result holder for this job
      Specified by:
      getResult in interface IPathJob
      Overrides:
      getResult in class AbstractPathJob
      Returns:

    • computeHeuristic

      protected double computeHeuristic(int x, int y, int z)
      Description copied from class: AbstractPathJob
      Compute the heuristic cost ('h' value) of a given position x,y,z.

      Returning a value of 0 performs a breadth-first search. Returning a value less than actual possible cost to goal guarantees shortest path, but at computational expense. Returning a value exactly equal to the cost to the goal guarantees shortest path and least expense (but generally. only works when path is straight and unblocked). Returning a value greater than the actual cost to goal produces good, but not perfect paths, and is fast. Returning a very high value (such that 'h' is very high relative to 'g') then only 'h' (the heuristic) matters as the search will be a very fast greedy best-first-search, ignoring cost weighting and distance.

      Specified by:
      computeHeuristic in class AbstractPathJob
      Returns:
      the heuristic.

    • isAtDestination

      protected boolean isAtDestination(@NotNull @NotNull MNode n)
      Description copied from class: AbstractPathJob
      Return true if the given node is a viable final destination, and the path should generate to here.
      Specified by:
      isAtDestination in class AbstractPathJob
      Parameters:
      n - Node to test.
      Returns:
      true if the node is a viable destination.

    • getEndNodeScore

      public double getEndNodeScore(MNode n)
      Description copied from class: AbstractPathJob
      Calculates a score for potential points where the path may end given no destination By default the heuristic for the closest node is used
      Specified by:
      getEndNodeScore in interface ISearchPathJob
      Overrides:
      getEndNodeScore in class AbstractPathJob
      Parameters:
      n - Node to test.
      Returns:
      score for the node, lower is better

    • isPassable

      protected boolean isPassable(@NotNull @NotNull net.minecraft.world.level.block.state.BlockState block, int x, int y, int z, MNode parent, boolean head)
      Description copied from class: AbstractPathJob
      Is the space passable.
      Overrides:
      isPassable in class AbstractPathJob
      Parameters:
      block - the block we are checking.
      parent - the parent node.
      head - the head position.
      Returns:
      true if the block does not block movement.
