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

onUse

public ActionResult onUse(BlockState state,
 World world,
 BlockPos pos,
 PlayerEntity player,
 Hand hand,

Called when this block is used by a player. This, by default, is bound to using the right mouse button.

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().

If the action result is successful on a logical client, then the action will be sent to the logical server for processing.

Overrides:

onUse in class AbstractBlock

Returns:

an action result that specifies if using the block was successful.

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.

appendProperties

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