canPlaceAt

public boolean canPlaceAt(BlockState state,
 WorldView world,
 BlockPos pos)

Returns whether the block can be placed at pos.

Blocks with supporting block requirements should override this method. Note that this should also be checked manually during AbstractBlock.getStateForNeighborUpdate(net.minecraft.block.BlockState, net.minecraft.util.math.Direction, net.minecraft.block.BlockState, net.minecraft.world.WorldAccess, net.minecraft.util.math.BlockPos, net.minecraft.util.math.BlockPos) in order to break the block that lost its supporting block.

This is only checked during the use of block items or by endermen, falling blocks, etc that can place blocks. This does not affect block state changes performed through World.setBlockState(BlockPos, BlockState) call.

This method is called on both the logical client and logical server, so take caution when overriding this method. The logical side can be checked using World.isClient.

Overrides:

canPlaceAt in class AbstractBlock

Returns:

whether the block can be placed at pos

onBlockAdded

public void onBlockAdded(BlockState state,
 World world,
 BlockPos pos,
 BlockState oldState,
 boolean notify)

Called server-side on the new block when the block state is changed. This includes block placement. When overriding this method, AbstractBlock.getStateForNeighborUpdate(net.minecraft.block.BlockState, net.minecraft.util.math.Direction, net.minecraft.block.BlockState, net.minecraft.world.WorldAccess, net.minecraft.util.math.BlockPos, net.minecraft.util.math.BlockPos) or AbstractBlock.neighborUpdate(net.minecraft.block.BlockState, net.minecraft.world.World, net.minecraft.util.math.BlockPos, net.minecraft.block.Block, net.minecraft.util.math.BlockPos, boolean) should also be overridden. The method is used in the following cases:

• When activating a redstone component on placement (used along with AbstractBlock.neighborUpdate(net.minecraft.block.BlockState, net.minecraft.world.World, net.minecraft.util.math.BlockPos, net.minecraft.block.Block, net.minecraft.util.math.BlockPos, boolean)
• When resetting a position-dependent state (see TargetBlock)
• When converting a block on placement (see WetSpongeBlock)
• When fire lights a portal

neighborUpdate

public void neighborUpdate(BlockState state,
 World world,
 BlockPos pos,
 Block sourceBlock,
 BlockPos sourcePos,
 boolean notify)

Called when a neighboring block is updated. This method should be overridden to perform an action with a side effect, most notably an activation of a redstone component. This can also be used to perform an action changing block states of other blocks, such as SpongeBlock which absorbs water.

To replace the state of the block itself, override AbstractBlock.getStateForNeighborUpdate(net.minecraft.block.BlockState, net.minecraft.util.math.Direction, net.minecraft.block.BlockState, net.minecraft.world.WorldAccess, net.minecraft.util.math.BlockPos, net.minecraft.util.math.BlockPos) instead.

private static boolean shouldDropRail(BlockPos pos,

getPistonBehavior

public PistonBehavior getPistonBehavior(BlockState state)

Returns how the piston should handle the block.

Notes on piston behavior:

• PistonBehavior.IGNORE is ignored for blocks.
• PistonBehavior.DESTROY and PistonBehavior.PUSH_ONLY causes pistons to ignore the block entity restriction.
• If the hardness equals -1.0f like bedrock, it blocks the piston regardless of the return value.
• Behavior of several unpushable blocks are hardcoded at PistonBlock.isMovable(net.minecraft.block.BlockState, net.minecraft.world.World, net.minecraft.util.math.BlockPos, net.minecraft.util.math.Direction, boolean, net.minecraft.util.math.Direction) instead.

Overrides:

onStateReplaced

public void onStateReplaced(BlockState state,
 World world,
 BlockPos pos,
 BlockState newState,
 boolean moved)

Called server-side on the old block when the block state is changed. This includes block removal. This is used to update neighboring blocks when an active redstone power source is removed, or to drop the contents of an inventory. The check state.isOf(newState.getBlock()) can be used to see if the block was removed or not.

getStateForNeighborUpdate

public BlockState getStateForNeighborUpdate(BlockState state,
 Direction direction,
 BlockState neighborState,
 WorldAccess world,
 BlockPos pos,
 BlockPos neighborPos)

Returns the state of the block after a neighboring block's state change.

Returning Blocks.AIR breaks the block. This is useful to implement supporting block requirement for blocks (if used along with AbstractBlock.canPlaceAt(net.minecraft.block.BlockState, net.minecraft.world.WorldView, net.minecraft.util.math.BlockPos)).

Side effects like activating a redstone component (but not scheduling a tick) should be performed in AbstractBlock.neighborUpdate(net.minecraft.block.BlockState, net.minecraft.world.World, net.minecraft.util.math.BlockPos, net.minecraft.block.Block, net.minecraft.util.math.BlockPos, boolean) instead. If the block supports waterlogging and currently has water, this method should be overridden to tick the fluid at the block's position.

This method is called on both the logical client and logical server, so take caution when overriding this method. The logical side can be checked using World.isClient. This is not called if Block.FORCE_STATE flag is set in the setBlockState call.

This method can be used for multiple purposes. Here are some examples:

• FenceBlock uses it to update the fence's connection when a horizontally neighboring block's state is changed.
• PlantBlock uses it to break the plant if the state change causes it to lose its supporting block.
• DoorBlock uses it to copy the state of the other half of the door.
• SlabBlock uses it to schedule the fluid to tick if waterlogged.
• SoulSandBlock uses it to schedule the water block above to tick so that it becomes a bubble column.
• FallingBlock uses it to schedule the block to tick so that it can fall if needed.

Overrides:

getStateForNeighborUpdate in class AbstractBlock

Parameters:

state - the state of this block

direction - the direction from this block to the neighbor

neighborState - the state of the updated neighbor block

world - the world

pos - the position of this block

neighborPos - the position of the neighbor block

Returns:

the state of the block after a neighboring block's state change

getFluidState

public FluidState getFluidState(BlockState state)

Returns the state's associated fluid state.

Waterloggable blocks must override this to return Fluids.WATER.getStill(false) when waterlogged.
