Method Details

appendProperties

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

Appends block state properties to this block. To use this, override and call StateManager.Builder.add(net.minecraft.state.property.Property<?>[]) inside the method. See Properties for the list of pre-defined properties.

Overrides:

onSteppedOn

public void onSteppedOn(World world,
 BlockPos pos,
 BlockState state,
 Entity entity)

Called when an entity steps on this block.

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.

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.

Overrides:

onStateReplaced in class AbstractBlock

• ItemScatterer.spawn(World, BlockPos, net.minecraft.inventory.Inventory)

scheduledTick

public 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). Additionally, AbstractBlock.randomTick(net.minecraft.block.BlockState, net.minecraft.server.world.ServerWorld, net.minecraft.util.math.BlockPos, net.minecraft.util.math.random.Random) by default calls this method; override AbstractBlock.randomTick(net.minecraft.block.BlockState, net.minecraft.server.world.ServerWorld, net.minecraft.util.math.BlockPos, net.minecraft.util.math.random.Random) to disable this behavior.

Scheduled ticks are often used inside 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).

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.

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

onStacksDropped

public void onStacksDropped(BlockState state,
 ServerWorld world,
 BlockPos pos,
 ItemStack tool,
 boolean dropExperience)

Called server-side when the stacks are dropped by mining or explosion. This is mostly overridden to drop experience orbs. To change the dropped item stacks, use loot tables or AbstractBlock.getDroppedStacks(net.minecraft.block.BlockState, net.minecraft.class_8567.class_8568). To drop inventory contents, use AbstractBlock.onStateReplaced(net.minecraft.block.BlockState, net.minecraft.world.World, net.minecraft.util.math.BlockPos, net.minecraft.block.BlockState, boolean) instead.

Experience orbs should only be dropped if dropExperience is true. Block.dropExperienceWhenMined(net.minecraft.server.world.ServerWorld, net.minecraft.util.math.BlockPos, net.minecraft.item.ItemStack, net.minecraft.util.math.intprovider.IntProvider) can be used to drop experience orbs. ExperienceDroppingBlock provides the implementation for experience-dropping blocks.

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.checkType(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;
 }
 

Specified by:

getTicker in interface BlockEntityProvider

Returns:

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