Hiding Rails and Blocks

Hello Guys, So ive been trying to make this for a while and I figured out it was sendBlockChange() I tried multiple ways of doing this like doing a command and it sends the block change but it doesn't work any ideas? I tried using worldedit too but that failed? any ideas!?

 

@floop222 @timtower has made that before, when he is available. I am sure he will help you.

 

@bwfcwalshy ok thx, I just need to learn the hiding bit

 

@timtower ProtocalLib wont work

 

@floop222

 

Code:

@SuppressWarnings("deprecation")
     @EventHandler
     public void getGrave(PlayerDeathEvent e) {
        System.out.println("event found");
    for(Player p : Bukkit.getOnlinePlayers()) {
             Location loc = e.getEntity().getLocation();
         Block block = loc.getBlock();
        
            Block signBlock = block.getRelative(BlockFace.NORTH).getRelative(BlockFace.EAST);
            p.sendBlockChange(signBlock.getLocation(), Material.SIGN_POST, (byte) 0xD);
                          String[] lines = {
                ChatColor.translateAlternateColorCodes('&', "&F&lR.I.P"),
                e.getEntity().getName(),
                "RIP",
            };         
            EntityPlayer player = ((CraftPlayer) p).getHandle();
        player.playerConnection.sendPacket(new PacketPlayOutUpdateSign(signBlock.getX(), signBlock.getY(), signBlock.getZ(), lines));
        p.sendBlockChange(block.getLocation(), Material.MOSSY_COBBLESTONE, block.getData());
             Block blockSkeleton = block.getRelative(BlockFace.UP);
             p.sendBlockChange(blockSkeleton.getLocation(), Material.SKULL, (byte) 0);
            Block redstone1 = block.getRelative(BlockFace.EAST);
            p.sendBlockChange(redstone1.getLocation(), Material.REDSTONE_WIRE, redstone1.getData());
             Block redstone2 = redstone1.getRelative(BlockFace.EAST);
            p.sendBlockChange(redstone2.getLocation(), Material.REDSTONE_WIRE, redstone2.getData());
             Block redstone3 = redstone2.getRelative(BlockFace.SOUTH);
            p.sendBlockChange(redstone3.getLocation(), Material.REDSTONE_WIRE, redstone3.getData());
            Block fire = redstone3.getRelative(BlockFace.WEST);
            p.sendBlockChange(fire.getLocation(), Material.FIRE, fire.getData());
        }
    }
}

That wont work

 

@floop222 Errors?

 

@bwfcwalshy it says it shouldn't be decapreated but I thought it should be

 

@floop222 Deprecated will still work.

 

@bwfcwalshy ok
