    Calculates a destination for the Entity to navigate to to reach the target entity, but does not set it as the current target.
    Calculates a destination for the Entity to navigate to, but does not set it as the current target.
     
     
    boolean
    If the entity is currently trying to navigate to a destination, this will return true
    default boolean
    Takes the result of a previous pathfinding calculation and sets it as the active pathfinding with default speed.

    Takes the result of a previous pathfinding calculation and sets it as the active pathfinding,
    default boolean

    default boolean
    moveTo​(@NotNull LivingEntity target, double speed)
    Calculates a destination for the Entity to navigate to to reach the target entity, and sets it with specified speed.
    default boolean
    Calculates a destination for the Entity to navigate to, and sets it with default speed as the current target.
    default boolean
    moveTo​(@NotNull Location loc, double speed)
    Calculates a destination for the Entity to navigate to, with desired speed as the current target.
    void
    setCanFloat​(boolean canFloat)
    Makes this pathfinder assume that the mob can float, or not
    void
    setCanOpenDoors​(boolean canOpenDoors)
    Allows this pathfinder to pass through closed doors, or not
    void
    setCanPassDoors​(boolean canPassDoors)

    void
    Instructs the Entity to stop trying to navigate to its current desired location
  • Method Details

    • getEntity

      @NotNull @NotNull Mob getEntity()
      Returns:
      The entity that is controlled by this pathfinder
    • stopPathfinding

      void stopPathfinding()
      Instructs the Entity to stop trying to navigate to its current desired location
    • hasPath

      boolean hasPath()
      If the entity is currently trying to navigate to a destination, this will return true
      Returns:
      true if the entity is navigating to a destination
    • getCurrentPath

      Returns:
      The location the entity is trying to navigate to, or null if there is no destination
    • findPath

      Calculates a destination for the Entity to navigate to, but does not set it as the current target. Useful for calculating what would happen before setting it.
      Parameters:
      loc - Location to navigate to
      Returns:
      The closest Location the Entity can get to for this navigation, or null if no path could be calculated
    • findPath

      Calculates a destination for the Entity to navigate to to reach the target entity, but does not set it as the current target. Useful for calculating what would happen before setting it. The behavior of this PathResult is subject to the games pathfinding rules, and may result in the pathfinding automatically updating to follow the target Entity. However, this behavior is not guaranteed, and is subject to the games behavior.
      Parameters:
      target - the Entity to navigate to
      Returns:
      The closest Location the Entity can get to for this navigation, or null if no path could be calculated
    • moveTo

      default boolean moveTo(@NotNull @NotNull Location loc)
      Calculates a destination for the Entity to navigate to, and sets it with default speed as the current target.
      Parameters:
      loc - Location to navigate to
      Returns:
      If the pathfinding was successfully started
    • moveTo

      default boolean moveTo(@NotNull @NotNull Location loc, double speed)
      Calculates a destination for the Entity to navigate to, with desired speed as the current target.
      Parameters:
      loc - Location to navigate to
      speed - Speed multiplier to navigate at, where 1 is 'normal'
      Returns:
      If the pathfinding was successfully started
    • moveTo

      default boolean moveTo(@NotNull @NotNull LivingEntity target)
      Calculates a destination for the Entity to navigate to to reach the target entity, and sets it with default speed. The behavior of this PathResult is subject to the games pathfinding rules, and may result in the pathfinding automatically updating to follow the target Entity. However, this behavior is not guaranteed, and is subject to the games behavior.
      Parameters:
      target - the Entity to navigate to
      Returns:
      If the pathfinding was successfully started
    • moveTo

      default boolean moveTo(@NotNull @NotNull LivingEntity target, double speed)
      Calculates a destination for the Entity to navigate to to reach the target entity, and sets it with specified speed. The behavior of this PathResult is subject to the games pathfinding rules, and may result in the pathfinding automatically updating to follow the target Entity.
