      This may cause loading of chunks! Some implementations may impose artificial restrictions on the maximum distance.

      Parameters:
      start - the start location
      direction - the ray direction
      maxDistance - the maximum distance
      Returns:
      the ray trace hit result, or null if there is no hit

    • rayTraceBlocks

      @Nullable RayTraceResult rayTraceBlocks​(@NotNull Location start, @NotNull Vector direction, double maxDistance, @NotNull FluidCollisionMode fluidCollisionMode)
      Performs a ray trace that checks for block collisions using the blocks' precise collision shapes.

      This takes collisions with passable blocks into account.

      This may cause loading of chunks! Some implementations may impose artificial restrictions on the maximum distance.

      Parameters:
      start - the start location
      direction - the ray direction
      maxDistance - the maximum distance
      fluidCollisionMode - the fluid collision mode

      @Nullable RayTraceResult rayTraceBlocks​(@NotNull Location start, @NotNull Vector direction, double maxDistance, @NotNull FluidCollisionMode fluidCollisionMode, boolean ignorePassableBlocks)
      Performs a ray trace that checks for block collisions using the blocks' precise collision shapes.

      If collisions with passable blocks are ignored, fluid collisions are ignored as well regardless of the fluid collision mode.

      Portal blocks are only considered passable if the ray starts within them. Apart from that collisions with portal blocks will be considered even if collisions with passable blocks are otherwise ignored.

      This may cause loading of chunks! Some implementations may impose artificial restrictions on the maximum distance.

      Parameters:
      start - the start location
      direction - the ray direction
      maxDistance - the maximum distance
      fluidCollisionMode - the fluid collision mode
      ignorePassableBlocks - whether to ignore passable but collidable blocks (ex. tall grass, signs, fluids, ..)
      Returns:
      the ray trace hit result, or null if there is no hit
    • rayTrace

      @Nullable RayTraceResult rayTrace​(@NotNull Location start, @NotNull Vector direction, double maxDistance, @NotNull FluidCollisionMode fluidCollisionMode, boolean ignorePassableBlocks, double raySize, @Nullable Predicate<Entity> filter)
      Performs a ray trace that checks for both block and entity collisions.

      Block collisions use the blocks' precise collision shapes. The raySize parameter is only taken into account for entity collision checks.

      If collisions with passable blocks are ignored, fluid collisions are ignored as well regardless of the fluid collision mode.

      Portal blocks are only considered passable if the ray starts within them. Apart from that collisions with portal blocks will be considered even if collisions with passable blocks are otherwise ignored.

      This may cause loading of chunks! Some implementations may impose artificial restrictions on the maximum distance.

      Parameters:
      start - the start location
      direction - the ray direction
      maxDistance - the maximum distance
      fluidCollisionMode - the fluid collision mode

    • locateNearestStructure

      @Nullable Location locateNearestStructure​(@NotNull Location origin, @NotNull StructureType structureType, int radius, boolean findUnexplored)
      Find the closest nearby structure of a given StructureType. Finding unexplored structures can, and will, block if the world is looking in chunks that gave not generated yet. This can lead to the world temporarily freezing while locating an unexplored structure.

      The radius is not a rigid square radius. Each structure may alter how many chunks to check for each iteration. Do not assume that only a radius x radius chunk area will be checked. For example, StructureType.WOODLAND_MANSION can potentially check up to 20,000 blocks away (or more) regardless of the radius used.

      This will not load or generate chunks. This can also lead to instances where the server can hang if you are only looking for unexplored structures. This is because it will keep looking further and further out in order to find the structure.

      Parameters:
      origin - where to start looking for a structure
      structureType - the type of structure to find
      radius - the radius, in chunks, around which to search
      findUnexplored - true to only find unexplored structures
      Returns:
      the closest Location, or null if no structure of the specified type exists.
    • getViewDistance

      int getViewDistance()
      Returns the view distance used for this world.
      Returns:
      the view distance used for this world
    • spigot

    • locateNearestRaid

      @Nullable Raid locateNearestRaid​(@NotNull Location location, int radius)
      Finds the nearest raid close to the given location.
      Parameters:
      location - the origin location
      radius - the radius
      Returns:
      the closest Raid, or null if no raids were found
    • getRaids

      @NotNull List<Raid> getRaids()
      Gets all raids that are going on over this world.
      Returns:
      the list of all active raids
    • getEnderDragonBattle

      @Nullable DragonBattle getEnderDragonBattle()
      Get the DragonBattle associated with this world. If this world's environment is not World.Environment.THE_END, null will be returned.

      If an end world, a dragon battle instance will be returned regardless of whether or not a dragon is present in the world or a fight sequence has been activated. The dragon battle instance acts as a state holder.

      Returns:
      the dragon battle instance
