Get relative block from sign?

Hello,

While developing a new plugin, I encountered a problem when getting lines from a relative sign. Currently, I want to get the third line of the sign (the xp) if the first line is equal to [XpBank] and if the second line is the player's name.

Code:

            Block downblock = sign.getBlock().getRelative(BlockFace.DOWN);
 
            if (downblock.getType().equals(Material.WALL_SIGN) || downblock.getType().equals(Material.SIGN_POST)) {
               
                Sign downblocksign = (Sign) block.getState();
 
                if (downblocksign.getLine(0).equalsIgnoreCase("[xpbank]") && downblocksign.getLine(1).equalsIgnoreCase(player.getName())
                        && downblocksign.getLine(2).equalsIgnoreCase("Store")) {
 
                    String str = downblocksign.getLine(3);
                    if (str.equalsIgnoreCase("")) {
                       
                        plugin.tell(player, "No xp stored in bank!");
                    }
                    Float f = new Float(str);
                    player.setExp(f);
                    downblocksign.setLine(3, "");
                    downblocksign.update();
 
                }
            }
        }

 

You are using the wrong "Sign" class, it has 2; Material and Block. Material.Sign is used to get the "content" of a sign (lines), the Block.Sign is used to understand its global aspects (where it is in the world).

you need to use:
org.bukkit.block.Sign

Not:
org.bukkit.material.Sign

You can leave everything as is, but for the part where you need to get the relative make sure to cast your sign as block:

Code:

Block relative = (org.bukkit.block.Sign)OriginalBlockSource;
relative.getRelative( BlockFace.DOWN );
