 For old versions, if you cannot access ''BlockEntityType.Builder.create'', try ''FabricBlockEntityTypeBuilder.create''.
-The block entity type defines that only the ''TutorialBlocks.DEMO_BLOCK'' can have this block entity type. If you want the block entity type to support more blocks, just add them in the parameters of ''BlockEntityType.Builder.create''. If the method reference ''DemoBlockEntity::new'' does not parse, check if the constructor of ''DemoBlockEntity'' has the correct parameters.

As for loot tables, [[blockentity_sync_itemstack|subsequent tutorials]] will cover how to improve the loot tables to include block entity data.
