randomTick

public void randomTick(BlockState state,
 ServerWorld world,
 BlockPos pos,
 Random random)

Called server-side when a block gets ticked randomly. This can be overridden to implement various logics, most commonly plant growth. Default implementation calls AbstractBlock.scheduledTick(net.minecraft.block.BlockState, net.minecraft.server.world.ServerWorld, net.minecraft.util.math.BlockPos, net.minecraft.util.math.random.Random). To control the rate of the action, use random.

Random tick speed is controlled by the game rule randomTickSpeed and can be disabled. Only blocks within 128-block cylinder (i.e. ignoring Y coordinates) around players receive random ticks.

Blocks overriding this must use AbstractBlock.Settings.ticksRandomly() block settings.

Here are some examples:

• SugarCaneBlock uses this to grow sugar cane.
• OxidizableBlock uses this to oxidize.
• NetherPortalBlock uses this to spawn zombified piglins.
• LeavesBlock uses this to decay when far from logs.

getFluidState

Returns the state's associated fluid state.

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

getDroppedStacks

public List<ItemStack> getDroppedStacks(BlockState state,
 LootContext.Builder builder)

Returns the block's dropped item stacks.

The default implementation uses loot tables. Blocks with custom drops should not hardcode the drops; instead, make a new loot table. If the loot table needs an additional context, override this method and modify builder before calling super.getDroppedStacks. An example of this is ShulkerBoxBlock. Note that to prevent item duplication, when appending item stacks to the builder, ItemStack.split(int) should be called.

This method should not be used for dropping inventory contents (AbstractBlock.onStateReplaced(net.minecraft.block.BlockState, net.minecraft.world.World, net.minecraft.util.math.BlockPos, net.minecraft.block.BlockState, boolean) should be used instead) or to drop experience orbs (AbstractBlock.onStacksDropped(net.minecraft.block.BlockState, net.minecraft.server.world.ServerWorld, net.minecraft.util.math.BlockPos, net.minecraft.item.ItemStack, boolean) should be used instead).

Overrides:

getDroppedStacks in class AbstractBlock

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

Overrides:

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

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.
