Interface Block

All Superinterfaces:

Metadatable

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!!!!

The Location object provided or null

getChunk

@NotNull
Chunk getChunk()

Gets the chunk which contains this block

Returns:

Containing Chunk

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)

getFace

@Nullable
BlockFace getFace(@NotNull
                  Block block)

 current.getFace(target) == BlockFace.Up;

                        FluidCollisionMode fluidCollisionMode)

Performs a ray trace that checks for collision with this specific block in its current state using its precise collision shape.

Parameters:

fluidCollisionMode - the fluid collision mode

Returns:

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
