    • generateTree

      boolean generateTree(@NotNull Location location, @NotNull Random random, @NotNull TreeType type)
      Creates a tree at the given Location
      Parameters:
      location - Location to spawn the tree
      random - Random to use to generated the tree
      type - Type of the tree to create
      Returns:
      true if the tree was created successfully, otherwise false

    • generateTree

      boolean generateTree(@NotNull Location location, @NotNull Random random, @NotNull TreeType type, @Nullable Consumer<BlockState> stateConsumer)
      Creates a tree at the given Location

      The provided consumer gets called for every block which gets changed as a result of the tree generation. When the consumer gets called no modifications to the world are done yet. Which means, that calling getBlockState(Location) in the consumer while return the state of the block before the generation.

      Modifications done to the BlockState in the consumer are respected, which means that it is not necessary to call BlockState.update()

      Parameters:
      location - Location to spawn the tree
      random - Random to use to generated the tree
      type - Type of the tree to create
      stateConsumer - The consumer which should get called for every block which gets changed
      Returns:
      true if the tree was created successfully, otherwise false

    • generateTree

      boolean generateTree(@NotNull Location location, @NotNull Random random, @NotNull TreeType type, @Nullable Predicate<BlockState> statePredicate)
      Creates a tree at the given Location

      The provided predicate gets called for every block which gets changed as a result of the tree generation. When the predicate gets called no modifications to the world are done yet. Which means, that calling getBlockState(Location) in the predicate will return the state of the block before the generation.

      If the predicate returns true the block gets set in the world. If it returns false the block won't get set in the world.

      Parameters:
      location - Location to spawn the tree
      random - Random to use to generated the tree
      type - Type of the tree to create
      statePredicate - The predicate which should get used to test if a block should be set or not.
      Returns:
      true if the tree was created successfully, otherwise false

    • spawnEntity

      @NotNull Entity spawnEntity(@NotNull Location location, @NotNull EntityType type)
      Creates a entity at the given Location
      Parameters:
      location - The location to spawn the entity
      type - The entity to spawn
      Returns:
      Resulting Entity of this method

    • spawnEntity

      @NotNull Entity spawnEntity(@NotNull Location loc, @NotNull EntityType type, boolean randomizeData)
      Creates a new entity at the given Location.
      Parameters:
      loc - the location at which the entity will be spawned.
      type - the entity type that determines the entity to spawn.
      randomizeData - whether or not the entity's data should be randomised before spawning. By default entities are randomised before spawning in regards to their equipment, age, attributes, etc. An example of this randomization would be the color of a sheep, random enchantments on the equipment of mobs or even a zombie becoming a chicken jockey. If set to false, the entity will not be randomised before spawning, meaning all their data will remain in their default state and not further modifications to the entity will be made. Notably only entities that extend the Mob interface provide randomisation logic for their spawn. This parameter is hence useless for any other type of entity.
      Returns:
      the spawned entity instance.

    • spawn

      @NotNull <T extends Entity> T spawn(@NotNull Location location, @NotNull Class<T> clazz) throws IllegalArgumentException
      Spawn an entity of a specific class at the given Location
      Type Parameters:
      T - the class of the Entity to spawn
      Parameters:
      location - the Location to spawn the entity at
      clazz - the class of the Entity to spawn
      Returns:
      an instance of the spawned Entity
      Throws:
      IllegalArgumentException - if either parameter is null or the Entity requested cannot be spawned

    • spawn

      @NotNull <T extends Entity> T spawn(@NotNull Location location, @NotNull Class<T> clazz, @Nullable Consumer<T> function) throws IllegalArgumentException
      Spawn an entity of a specific class at the given Location, with the supplied function run before the entity is added to the world.
      Note that when the function is run, the entity will not be actually in the world. Any operation involving such as teleporting the entity is undefined until after this function returns.
      Type Parameters:
      T - the class of the Entity to spawn
      Parameters:
      location - the Location to spawn the entity at
      clazz - the class of the Entity to spawn
      function - the function to be run before the entity is spawned.
      Returns:
      an instance of the spawned Entity
      Throws:
      IllegalArgumentException - if either parameter is null or the Entity requested cannot be spawned

    • spawn

      @NotNull <T extends Entity> T spawn(@NotNull Location location, @NotNull Class<T> clazz, boolean randomizeData, @Nullable Consumer<T> function) throws IllegalArgumentException
      Creates a new entity at the given Location with the supplied function run before the entity is added to the world.
      Note that when the function is run, the entity will not be actually in the world. Any operation involving such as teleporting the entity is undefined until after this function returns. The passed function however is run after the potential entity's spawn randomization and hence already allows access to the values of the mob, whether or not those were randomized, such as attributes or the entity equipment.
      Type Parameters:
      T - the generic type of the entity that is being created.
      Parameters:
      location - the location at which the entity will be spawned.
      clazz - the class of the Entity that is to be spawned.
      randomizeData - whether or not the entity's data should be randomised before spawning. By default entities are randomised before spawning in regards to their equipment, age, attributes, etc. An example of this randomization would be the color of a sheep, random enchantments on the equipment of mobs or even a zombie becoming a chicken jockey. If set to false, the entity will not be randomised before spawning, meaning all their data will remain in their default state and not further modifications to the entity will be made. Notably only entities that extend the Mob interface provide randomisation logic for their spawn. This parameter is hence useless for any other type of entity.
      function - the function to be run before the entity is spawned.
      Returns:
      the spawned entity instance.
      Throws:
      IllegalArgumentException - if either the world or clazz parameter are null.
