I am working on trying to update my 1.7.10 mod to Minecraft 1.8.9 and I am trying to use the json modelling system to implement the different facing directions in my blocks. My block originally worked fine before I attempted this but now I have messed it up and I can no longer place the block. I tried following the Intro to Blockstates guide on Read The Docs and I looked at the BlockFurnace vanilla code, but there must still be something I am missing. Here is what I have so far.

    {
        EnumFacing enumfacing = EnumFacing.getFront(meta);

        if (enumfacing.getAxis() == EnumFacing.Axis.Y)
        {
            enumfacing = EnumFacing.NORTH;

            Block block2 = worldIn.getBlockState(pos.west()).getBlock();
            Block block3 = worldIn.getBlockState(pos.east()).getBlock();
            EnumFacing enumfacing = (EnumFacing)state.getValue(DIRECTION);

            if (enumfacing == EnumFacing.NORTH && block.isFullBlock() && !block1.isFullBlock())
            {
                enumfacing = EnumFacing.SOUTH;
            }
            else if (enumfacing == EnumFacing.SOUTH && block1.isFullBlock() && !block.isFullBlock())
            {
                enumfacing = EnumFacing.NORTH;
            }
            else if (enumfacing == EnumFacing.WEST && block2.isFullBlock() && !block3.isFullBlock())
            {
                enumfacing = EnumFacing.EAST;
            }
            else if (enumfacing == EnumFacing.EAST && block3.isFullBlock() && !block2.isFullBlock())
            {
                enumfacing = EnumFacing.WEST;
            }

            worldIn.setBlockState(pos, state.withProperty(DIRECTION, enumfacing), 2);
        }
    }
}

Thanks for any help!

Problem was solved

1. In your call to setDefaultState, don't create a new BlockState instance, just call setDefaultState with blockState.withProperty(DIRECTION, EnumFacing.NORTH)

2. You should have @Override on your onBlockAdded method, if you did you'd see that you've got the signature wrong. It takes several additional parameters and returns the IBlockState to place in the world. Instead of calling setBlockState, you'd simply return the correct state.

Thanks that fixed everything. My code for future reference.
