The method getAttachedFace() is undefined for the type MaterialData

I have look for numerous hours on google, and come up with nothing. I simply want to find out if a sign is on a chest. After all my googling I have come up with the following:

Code:java

if (b.getType() == Material.SIGN_POST || b.getType() == Material.WALL_SIGN){
Sign sign = (Sign) b.getState();
if(sign.getBlock().getRelative(sign.getData().getAttachedFace()).equals(Material.CHEST)){
//do code blah blah blah
}

It simply comes up with

Code:

The method getAttachedFace() is undefined for the type MaterialData

Note: I am importing the Block, not Material, and the event is SignChangeEvent

EDIT: Whole class so far:

Code:java

package com.mc123isme1.post;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.block.Sign;
import org.bukkit.block.Block;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.SignChangeEvent;
import org.bukkit.material.Attachable;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener{
    public void onEnable(){
        Bukkit.getPluginManager().registerEvents(this, this);
    }
    @EventHandler
    public void onSignPost(SignChangeEvent e){
        Player p = e.getPlayer();
        Block b = e.getBlock();
 
        if(e.getLine(0).equalsIgnoreCase("[post]")){
                if(e.getLine(1).equalsIgnoreCase(p.getName())){
                    if (b.getType() == Material.SIGN_POST || b.getType() == Material.WALL_SIGN) {
                        Sign sign = (Sign) b.getState();
                        if(sign.getBlock().getRelative(sign.getData().getAttachedFace()).equals(Material.CHEST)){
                    e.setLine(0, "[" + ChatColor.GREEN + "Post" + ChatColor.RESET + "]");
                    }
                }
            }
        }
    }
}

 

Cast sign.getData() to org.bukkit.material.Sign:

((org.bukkit.material.Sign) sign.getData()).getAttachedFace()

 

Zupsub hmm, no errors, but it just doesn't work

 

Does it recognize the right block? Which checks it instead? Btw. Please update your posted code to the current one then.

 

Here it is Zupsub

Code:java

package com.mc123isme1.post;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.block.Sign;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.SignChangeEvent;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener{
    public void onEnable(){
        Bukkit.getPluginManager().registerEvents(this, this);
    }
    @EventHandler
    public void onSignPost(SignChangeEvent e){
        Player p = e.getPlayer();
        Block b = e.getBlock();
 
        if(e.getLine(0).equalsIgnoreCase("[post]")){
                if(e.getLine(1).equalsIgnoreCase(p.getName())){
                    if (b.getType() == Material.SIGN_POST || b.getType() == Material.WALL_SIGN) {
                        Sign sign = (Sign) b.getState();
                        if(sign.getBlock().getRelative(((org.bukkit.material.Sign) sign.getData()).getAttachedFace()).equals(Material.CHEST)){
                    e.setLine(0, "[" + ChatColor.GREEN + "Post" + ChatColor.RESET + "]");
                    }
                }
            }
        }
    }
}

Zupsub just a second, it seems that I am compiling and testing on different versions

Zupsub Tested on same versions, still doesn't work

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Your code won't work and shouldn't be compiling at all. You need to check if the block is a sign and if so perform the cast to org.bukkit.block.Sign *before* you try to check what lines the sign contains.

 

eh nvm, I sortof gave up on the plugin, ran into a dead end on another part.
