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.

Overrides:

copyItemDataRequiresOperator in class BlockEntity

Returns:

whether the block item should require the player to have operator permissions to copy the block entity data on placement

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

writeNbt

protected void writeNbt(NbtCompound nbt,

Writes data to 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.
