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 AbstractRedstoneGateBlock.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 AbstractRedstoneGateBlock.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

scheduledTick

protected void scheduledTick(BlockState state,
 ServerWorld world,
 BlockPos pos,
 Random random)

Called server-side when a block receives a scheduled tick. This can be used like a timer. Scheduled ticks are added using WorldAccess.scheduleBlockTick(BlockPos, Block, int).

Scheduled ticks are often used inside 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).

Here are some examples:

• SugarCaneBlock checks the placement requirement.
• DispenserBlock dispenses its content.
• CommandBlock executes its command.
• FrogspawnBlock spawns a tadpole.
• SoulSandBlock updates a bubble column.
• FallingBlock tries to fall.

Handles the block event, which is an event specific to a block with an integer ID and data.

Overrides:

createBlockEntity

public BlockEntity createBlockEntity(BlockPos pos,
 BlockState state)

Returns a new block entity instance.

For example:

 @Override
 public BlockEntity createBlockEntity(BlockPos pos, BlockState state) {
   return new MyBlockEntity(pos, state);
 }
 

Specified by:

createBlockEntity in interface BlockEntityProvider

Returns:

a new block entity instance

Implementation Note:

While this is marked as nullable, in practice this should never return null. PistonExtensionBlock is the only block in vanilla that returns null inside the implementation.

appendProperties

protected void appendProperties(StateManager.Builder<Block,BlockState> builder)
