canPlaceAt

protected 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 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

getStateForNeighborUpdate

protected 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 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 AbstractSignBlock

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

Returns a new block entity instance.

getTicker

@Nullable
public <T extends BlockEntity>
@Nullable BlockEntityTicker<T> getTicker(World world,
 BlockState state,
 BlockEntityType<T> type)

Returns the "ticker" for the block's block entity, or null if the block entity does not need to be ticked.

Ticker is a functional interface called every tick to tick the block entity on both the client and the server.

Tickers should validate that the passed type is the one this block expects, and return null if it isn't. This is to prevent crashes in rare cases where a mismatch occurs between the position's block and block entity. BlockWithEntity.validateTicker(net.minecraft.block.entity.BlockEntityType<A>, net.minecraft.block.entity.BlockEntityType<E>, net.minecraft.block.entity.BlockEntityTicker<? super E>) can be used to implement the check.

Example:

 public <T extends BlockEntity> BlockEntityTicker<T> getTicker(World world, BlockState state, BlockEntityType<T> type) {
   if (type != YourMod.MY_BLOCK_ENTITY_TYPE) return null;
   // This should be a static method usable as a BlockEntityTicker.
   return YourBlockEntity::tick;
 }
