Interface Block

public interface Block
extends Metadatable
Represents a block. This is a live object, and only one Block may exist for any given location in a world. The state of the block may change concurrently to your own handling of it; use block.getState() to get a snapshot state of a block which will not be modified.
Note that parts of this class which require access to the world at large (i.e. lighting and power) may not be able to be safely accessed during world generation when used in cases like BlockPhysicsEvent!!!!

    • setBlockData

      void setBlockData​(@NotNull BlockData data)
      Sets the complete data for this block
      Parameters:
      data - new block specific data
    • setBlockData

      void setBlockData​(@NotNull BlockData data, boolean applyPhysics)
      Sets the complete data for this block
      Note that applyPhysics = false is not in general safe. It should only be used when you need to avoid triggering a physics update of neighboring blocks, for example when creating a Bisected block. If you are using a custom populator, then this parameter may also be required to prevent triggering infinite chunk loads on border blocks. This method should NOT be used to "hack" physics by placing blocks in impossible locations. Such blocks are liable to be removed on various events such as world upgrades. Furthermore setting large amounts of such blocks in close proximity may overload the server physics engine if an update is triggered at a later point. If this occurs, the resulting behavior is undefined.
      Parameters:
      data - new block specific data
      applyPhysics - false to cancel physics from the changed block
    • setType

      void setType​(@NotNull Material type)
      Sets the type of this block
      Parameters:
      type - Material to change this block to
    • setType

      void setType​(@NotNull Material type, boolean applyPhysics)
      Sets the type of this block
      Note that applyPhysics = false is not in general safe. It should only be used when you need to avoid triggering a physics update of neighboring blocks, for example when creating a Bisected block. If you are using a custom populator, then this parameter may also be required to prevent triggering infinite chunk loads on border blocks.

      Parameters:
      type - Material to change this block to
      applyPhysics - False to cancel physics on the changed block.
    • getFace

      @Nullable BlockFace getFace​(@NotNull Block block)
      Gets the face relation of this block compared to the given block.

      For example:

      
       Block current = world.getBlockAt(100, 100, 100);
       Block target = world.getBlockAt(100, 101, 100);
      
       current.getFace(target) == BlockFace.Up;
       

      If the given block is not connected to this block, null may be returned
      Parameters:
      block - Block to compare against this block
      Returns:
      BlockFace of this block which has the requested block, or null
    • getState

    • getBoundingBox

      @NotNull BoundingBox getBoundingBox()
      Gets the approximate bounding box for this block.

      This isn't exact as some blocks Stairs contain many bounding boxes to establish their complete form. Also, the box may not be exactly the same as the collision shape (such as cactus, which is 16/16 of a block with 15/16 collisional bounds). This method will return an empty bounding box if the geometric shape of the block is empty (such as air blocks).

      Returns:
      the approximate bounding box of the block
