In a worldgen.generate() function, this returns null:

IBlockState stone = Block.getBlockFromName("minecraft:polished_diorite").getDefaultState();

 

but this returns a valid state:

IBlockState stone = Block.getBlockFromName("minecraft:stone").getDefaultState();

 

Also this returns a valid state:

IBlockState stone = Blocks.STONE.getDefaultState();

 

So how would I create a polished diorite? As far as I can tell "minecraft:polished_diorite" is the correct name, but it is not recognized. Also there is no Blocks.POLISHED_DIORITE or anything like it.

 

Thanks!

Blocks have states.

Those states contain extra information.

Like what kind of stone the stone is.

 

Polished diorite is a variant of minecraft:stone.

 

Also, stop using getFromName and just use the constants in the Blocks class.

Thanks! That led me to this, which works:

IBlockState stone = Blocks.STONE.getDefaultState().withProperty(BlockStone.VARIANT, BlockStone.EnumType.DIORITE_SMOOTH);
