Method Details

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 BlockEntity.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

Returns:

the serialized state of this block entity that is observable by clients

readData

protected void readData(ReadView view)

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:

readData in class BlockEntity
