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.

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.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; 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.

Overrides:

onSyncedBlockEvent

public boolean onSyncedBlockEvent(BlockState state,
 World world,
 BlockPos pos,
 int type,
 int data)

Handles the block event, which is an event specific to a block with an integer ID and data.

Overrides:

onSyncedBlockEvent in class AbstractBlock

Returns:

whether the event was handled successfully

createBlockEntity

public BlockEntity createBlockEntity(BlockPos pos,
 BlockState state)

Returns a new block entity instance.

For example:

 @Override
 public BlockEntity createBlockEntity(BlockPos pos, BlockState state) {
   return new MyBlockEntity(pos, state);
 }
 

Specified by:

createBlockEntity in interface BlockEntityProvider

Returns:

a new block entity instance

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:
