BlockProperties are what makes a block distinctive from other blocks. It mainly serves as superinterface to IBlockState, that means all these functions are also available to all IBlockState objects.

It might be required for you to import the package if you encounter any issues, so better be safe than sorry and add the import.
import crafttweaker.block.IBlockProperties;
