      The creature type's name if is set.

    • getDelay

      int getDelay()
      Get the spawner's delay.
      This is the delay, in ticks, until the spawner will spawn its next mob.

      The delay.

    • setDelay

      void setDelay(int delay)
      Set the spawner's delay.

      Parameters:
      delay - The delay.

    • getMinSpawnDelay

      int getMinSpawnDelay()
      The minimum spawn delay amount (in ticks).
      This value is used when the spawner resets its delay (for any reason). It will choose a random number between getMinSpawnDelay() and getMaxSpawnDelay() for its next getDelay().
      Default value is 200 ticks.
      Returns:
      the minimum spawn delay amount

    • setMinSpawnDelay

      delay - the minimum spawn delay amount
      See Also:

    • getMaxSpawnDelay

      int getMaxSpawnDelay()
      The maximum spawn delay amount (in ticks).
      This value is used when the spawner resets its delay (for any reason). It will choose a random number between getMinSpawnDelay() and getMaxSpawnDelay() for its next getDelay().
      This value must be greater than 0 and less than or equal to getMaxSpawnDelay().
      Default value is 800 ticks.
      Returns:
      the maximum spawn delay amount

    • setMaxSpawnDelay

      void setMaxSpawnDelay(int delay)

      the current spawn count

    • setSpawnCount

      void setSpawnCount(int spawnCount)
      Set how many mobs attempt to spawn.
      Parameters:
      spawnCount - the new spawn count

    • getMaxNearbyEntities

      int getMaxNearbyEntities()
      Set the new maximum amount of similar entities that are allowed to be within spawning range of this spawner.
      If more than the maximum number of entities are within range, the spawner will not spawn and try again with a new getDelay().
      Default value is 16.
      Returns:
      the maximum number of nearby, similar, entities

    • setMaxNearbyEntities

      void setMaxNearbyEntities(int maxNearbyEntities)
      Set the maximum number of similar entities that are allowed to be within spawning range of this spawner.
      Similar entities are entities that are of the same EntityType
      Parameters:
      maxNearbyEntities - the maximum number of nearby, similar, entities

    • getRequiredPlayerRange

      int getRequiredPlayerRange()
      Get the maximum distance(squared) a player can be in order for this spawner to be active.
      If this value is less than or equal to 0, this spawner is always active (given that there are players online).
      Default value is 16.
      Returns:
      the maximum distance(squared) a player can be in order for this spawner to be active.

    • setRequiredPlayerRange

      void setRequiredPlayerRange(int requiredPlayerRange)
      Set the maximum distance (squared) a player can be in order for this spawner to be active.
      Setting this value to less than or equal to 0 will make this spawner always active (given that there are players online).

      requiredPlayerRange - the maximum distance (squared) a player can be in order for this spawner to be active.

    • getSpawnRange

      Get the radius around which the spawner will attempt to spawn mobs in.
      This area is square, includes the block the spawner is in, and is centered on the spawner's x,z coordinates - not the spawner itself.
      It is 2 blocks high, centered on the spawner's y-coordinate (its bottom); thus allowing mobs to spawn as high as its top surface and as low as 1 block below its bottom surface.
      Default value is 4.

      the spawn range

    • setSpawnRange

      The weight will determine how often this entry is chosen to spawn, higher weighted entries will spawn more often than lower weighted ones.

      Parameters:
      snapshot - the snapshot that will be spawned
      weight - the weight

    • getPotentialSpawns

      @NotNull @NotNull List<SpawnerEntry> getPotentialSpawns()
      Gets a list of potential spawns from this spawner or an empty list if no entities have been assigned to this spawner.
      Changes made to the returned list will not be reflected in the spawner unless applied with setPotentialSpawns(java.util.Collection<org.bukkit.block.spawner.SpawnerEntry>)
      Returns:
      a list of potential spawns from this spawner, or an empty list if no entities have been assigned to this spawner
