getRelative()

Hi so im trying to make a barbed wire plugin and I dont whant to use a block place event, I whant to use the iterract, then get the clicked side then add a web on it, but the problem is that it places 6 webs all around...

help?

Code:

@EventHandler
    public void onWebPlace(PlayerInteractEvent e)
    {
      
        Player p = e.getPlayer();
        final Block b = e.getClickedBlock();
        ItemStack i = e.getItem();
      
        if ((e.getAction() == Action.RIGHT_CLICK_BLOCK) &&
                (i != null) &&
                (b.getType() != Material.WATER) &&
                (i.getType() == Material.WEB))
                {
                   Location Web = new Location(p.getWorld(), b.getX(), b.getY(), b.getZ());
                  
                   //
                   if(b.getLocation().getBlock().getRelative(BlockFace.EAST, 1) != null)
                   {
                      Web.add(-1, 0, 0).getBlock().setType(Material.WEB);
                      Webs.put(Web, b.getType());
                   }
                   if(b.getLocation().getBlock().getRelative(BlockFace.WEST, 1) != null)
                   {
                      Web.add(2, 0, 0).getBlock().setType(Material.WEB);
                      Webs.put(Web, b.getType());
                   }
                   //
                   if(b.getLocation().getBlock().getRelative(BlockFace.NORTH, 1) != null)
                   {
                      Web.add(-1, 0, -1).getBlock().setType(Material.WEB);
                      Webs.put(Web, b.getType());
                   }
                   if(b.getLocation().getBlock().getRelative(BlockFace.SOUTH, 1) != null)
                   {
                      Web.add(0, 0, 2).getBlock().setType(Material.WEB);
                      Webs.put(Web, b.getType());
                   }
                   //
                   if(b.getLocation().getBlock().getRelative(BlockFace.UP, 1) != null)
                   {
                      Web.add(0, -1, -1).getBlock().setType(Material.WEB);
                      Webs.put(Web, b.getType());
                   }
                   if(b.getLocation().getBlock().getRelative(BlockFace.DOWN, 1) != null)
                   {
                      Web.add(0, 2, 0).getBlock().setType(Material.WEB);
                      Webs.put(Web, b.getType());
                   }
                
                  
                    p.getWorld().playSound(p.getLocation(), Sound.ANVIL_LAND, 1.0F, 1.0F);
                  
                }
    }

 

the query "b.getLocation().getBlock().getRelative(BlockFace.NORTH, 1) != null" will never exist, cause a bock on a location is never null. It might be the type (b.getLocation().getBlock().getType()) "Material.AIR".
