scheduledTickCalled server-side when a block receives a scheduled tick. This can be used like a timer. Scheduled ticks are added usingScheduledTickView.scheduleBlockTick(BlockPos, Block, int).Scheduled ticks are often used inside getStateForNeighborUpdate(net.minecraft.block.BlockState, net.minecraft.world.WorldView, net.minecraft.world.tick.ScheduledTickView, net.minecraft.util.math.BlockPos, net.minecraft.util.math.Direction, net.minecraft.util.math.BlockPos, net.minecraft.block.BlockState, net.minecraft.util.math.random.Random).Here are some examples: - SugarCaneBlockchecks the placement requirement.
- DispenserBlockdispenses its content.
- CommandBlockexecutes its command.
- FrogspawnBlockspawns a tadpole.
- SoulSandBlockupdates a bubble column.
- FallingBlocktries to fall.

getStateForNeighborUpdateprotected BlockState getStateForNeighborUpdate(BlockState state, WorldView world, ScheduledTickView tickView, BlockPos pos, Direction direction, BlockPos neighborPos, BlockState neighborState, Random random) Returns the state of the block after a neighboring block's state change.Returning Blocks.AIRbreaks the block. This is useful to implement supporting block requirement for blocks (if used along withAbstractBlock.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.world.block.WireOrientation, 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 ifBlock.FORCE_STATEflag is set in thesetBlockStatecall.This method can be used for multiple purposes. Here are some examples: - FenceBlockuses it to update the fence's connection when a horizontally neighboring block's state is changed.
- PlantBlockuses it to break the plant if the state change causes it to lose its supporting block.
- DoorBlockuses it to copy the state of the other half of the door.
- SlabBlockuses it to schedule the fluid to tick if waterlogged.
- SoulSandBlockuses it to schedule the water block above to tick so that it becomes a bubble column.
- FallingBlockuses it to schedule the block to tick so that it can fall if needed.
 - Overrides:
- getStateForNeighborUpdatein class- AbstractBlock
- Parameters:
- state- the state of this block
- world- the world
- pos- the position of this block
- direction- the direction from this block to the neighbor

onBlockAddedprotected 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,getStateForNeighborUpdate(net.minecraft.block.BlockState, net.minecraft.world.WorldView, net.minecraft.world.tick.ScheduledTickView, net.minecraft.util.math.BlockPos, net.minecraft.util.math.Direction, net.minecraft.util.math.BlockPos, net.minecraft.block.BlockState, net.minecraft.util.math.random.Random)orAbstractBlock.neighborUpdate(net.minecraft.block.BlockState, net.minecraft.world.World, net.minecraft.util.math.BlockPos, net.minecraft.block.Block, net.minecraft.world.block.WireOrientation, 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.world.block.WireOrientation, boolean)

onStateReplacedprotected 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 checkstate.isOf(newState.getBlock())can be used to see if the block was removed or not.For most block entities, ItemScatterer.onStateReplaced(net.minecraft.block.BlockState, net.minecraft.block.BlockState, net.minecraft.world.World, net.minecraft.util.math.BlockPos)provides a good implementation of this method.
