  • Method Details

    • readNbt

      protected void readNbt(NbtCompound nbt, RegistryWrapper.WrapperLookup registries)
      Reads data from nbt. Subclasses should override this if they store a persistent data.

      NBT is a storage format; therefore, a data from NBT is loaded to a block entity instance's fields, which are used for other operations instead of the NBT. The data is written back to NBT when saving the block entity.

      nbt might not have all expected keys, or might have a key whose value does not meet the requirement (such as the type or the range). This method should fall back to a reasonable default value instead of throwing an exception.

      Overrides:
      readNbt in class BlockEntity

    • toUpdatePacket

      public BlockEntityUpdateS2CPacket toUpdatePacket()
      Description copied from class: BlockEntity
      Returns the packet to send to nearby players when the block entity's observable state changes, or null to not send the packet.

      If the data returned by initial chunk data is suitable for updates, the following shortcut can be used to create an update packet: BlockEntityUpdateS2CPacket.create(this). The NBT will be passed to BlockEntity.readNbt(net.minecraft.nbt.NbtCompound, net.minecraft.registry.RegistryWrapper.WrapperLookup) on the client.

      "Observable state" is a state that clients can observe without specific interaction. For example, CampfireBlockEntity's cooked items are observable states, but chests' inventories are not observable states, since the player must first open that chest before they can see the contents.

      To sync block entity data using this method, use serverWorld.getChunkManager().markForUpdate(this.getPos());.

      Overrides:
      toUpdatePacket in class BlockEntity
      Returns:
      the packet to send to nearby players when the block entity's observable state changes, or null to not send the packet

    • toInitialChunkDataNbt

      public NbtCompound toInitialChunkDataNbt(RegistryWrapper.WrapperLookup registries)
      Returns the serialized state of this block entity that is observable by clients.

      This is sent alongside the initial chunk data, as well as when the block entity implements toUpdatePacket() and decides to use the default BlockEntityUpdateS2CPacket.

      "Observable state" is a state that clients can observe without specific interaction. For example, CampfireBlockEntity's cooked items are observable states, but chests' inventories are not observable states, since the player must first open that chest before they can see the contents.

      To send all NBT data of this block entity saved to disk, return BlockEntity.createNbt(net.minecraft.registry.RegistryWrapper.WrapperLookup).

      Overrides:
      toInitialChunkDataNbt in class BlockEntity

    • copyItemDataRequiresOperator

      public boolean copyItemDataRequiresOperator()
      Returns whether the block item should require the player to have operator permissions to copy the block entity data on placement.

      Block entities that can execute commands should override this to return true.
