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 asSpongeBlock
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.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:

scheduledTick
Called server-side when a block receives a scheduled tick. This can be used like a timer. Scheduled ticks are added usingWorldAccess.createAndScheduleBlockTick(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; overrideAbstractBlock.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.

onUse
public ActionResult onUse(BlockState state, World world, BlockPos pos, PlayerEntity player, Hand hand, BlockHitResult hit) 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.
