Solved Set block direction

I want to know how to set the block facing. like how to rotate stairs and such...
Since the damage value has been removed I dont know how to do this.


EDIT:

This works

Code:

Block block = player.getLocation().getBlock();
block.setType(Material.STICKY_PISTON);
BlockData blockData = block.getBlockData();
if (blockData instanceof Directional) {
  ((Directional) blockData).setFacing(BlockFace.WEST);
  block.setBlockData(blockData);
}

 

@The_Spaceman

if(block instanceof Directional)
{
((Directional) b).setFacingDirection(BlockFace.EAST);
}
that should work i think

 

That doesn't work. You can't cast Block to Directional.

In the class Directional there is no .setFacingDirection, only .setFacing()

and block.getBlockData() is not castable to Directional.
