Config on sign help?

I am trying to pull a value from the config file onto a sign when a certain phrase is typed on the first line.

PHP:

package com.tammcd.troubleinminecraft;
 
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.SignChangeEvent;
 
public class SignListener implements Listener{
 
    public static Main plugin;
   
    public SignListener(Main instance){
        plugin = instance;
    }
   
    @EventHandler
    public void onSignCreate(SignChangeEvent sign){
        Player player = sign.getPlayer();
        if(sign.getLine(0).equalsIgnoreCase("example")){
            player.sendMessage(ChatColor.GOLD + "The sign has been changed");
            sign.setLine(0, .getConfig().getString("motd"));
 
        }
    }
}


But I get an error under the .getConfig() part. Saying: "The method .getConfig() is undefined for the type SignListener."

Any ideas how to get it working?

 

Code:

sign.setLine(0, .getConfig().getString("motd"));

Either add a "this" pointer in front of the ".getConfig()" method or remove the dot. Local methods don't need a dot. Becomes :

Code:

sign.setLine(0, this.getConfig().getString("motd"));

or

Code:

sign.setLine(0, getConfig().getString("motd"));

 

When I add the 'this' or remove the '.' I still get the same error saying "The method .getConfig() is undefined for the type SignListener."

 

You need to point it to where you originally defined the getConfig(), it is probably in your main, so use;

Main:

Code:java

 
public void onEnable(){
FileConfiguration config = getConfig();
}
 

Listener:

Code:java

 
sign.setLine(0, config.getString("motd"));
 

Or something like that.

 

Okay I have added the FileConfiguration config = getConfig(); line to the Main class and change the SignListener line.

I get an error below the word config on this line:

Code:

 sign.setLine(0, config.getString("motd"));

Saying: "config cannot be resolved" and there are fixes such as create local variable 'config' and create field 'config'

 

plugin.config.getString();

You need to tell it that config is in the main class, which is given the variable of plugin (If that makes sense).

Sorry.

 

Yes that makes sense, I have added plugin to that line to it is now:

Code:

sign.setLine(0, plugin.config.getString("motd"));

But I get an error under the config still, this time saying: config cannot be resolved or is not a field. And there are two fixes: create type 'config' in type 'Main' and create constant 'config' in type 'Main'

When ever I try and use either one of the fixes it gets rid of the error under config and the.getString() part has an error saying: The method getString(String) is undefined for the type Object and the fix is: Add cast to 'plugin.config'.

 

Code:

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.SignChangeEvent;
 
public class SignListener implements Listener{
 
    String motd = plugin.getConfig().getString("motd");
 
    public static Main plugin;
 
    public SignListener(Main instance){
        plugin = instance;
    }
 
    @EventHandler
    public void onSignCreate(SignChangeEvent sign){
        Player player = sign.getPlayer();
        if(sign.getLine(0).equalsIgnoreCase("example")){
            player.sendMessage(ChatColor.GOLD + "The sign has been changed");
            sign.setLine(0, motd);
 
        }
    }
}

I have it different in my plugin, can't remember how though.

Way above works though, tested it. You can do it with or without the motd variable.

 

I tried doing that but I get a lovely error in my console:

[SEVERE] Could not load 'plugins\TroubleInMinecraft.jar' in folder 'plugins'
org.bukkit.plugin.InvalidPluginException: java.lang.NullPoitnerException at org.bukkit.plugin.java.JavaPluginLoader.loadPlugin<JavaPluginLoader.java:153>

The error does reference some of my classes:

Caused by: java.lang.NullPointerException
at com.tammcd.troubleinminecraft.SignListsner.<init><SignListsner.java:1>
at com.tammcd.troubleinminecraft.Main<init><Main.java:54>

This is what is on line 54 of the Main class:

PHP:

public final SignListener sl = new SignListener(this);

 

Try;

Code:

public SignListener sl;
 
public void onEnable(){
sl = new SignListener(this);
//Everything else here
}

 

I did that, I then got another error in the console:

[SEVERE] Error occurred while enabling Trouble In Minacraft <Is it up to date?>
java.lang.NullPointerException
at com.tammcd.troubleinminecraft.SignListener.<init><SignListener.java:11>
at com.tammcd.troubleinminecraft.Main.onEnable<Main.java:71>

This code is at line 11 in the SignListener class:

PHP:

String motd = plugin.getConfig().getString("motd");

This code is at line 71 in the Main class:

PHP:

sl = new SignListener(this);

 

Mind posting everything then? (Both classes), will take a better look at it with eclipse.

 

Sure.

Here is the main class:

PHP:

Here is the SignListener class.

PHP:

package com.tammcd.troubleinminecraft;
 
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.SignChangeEvent;
 
public class SignListener implements Listener{
 
        String motd = plugin.getConfig().getString("motd");
 
        public static Main plugin;
 
        public SignListener(Main instance){
            plugin = instance;
        }
 
        @EventHandler
        public void onSignCreate(SignChangeEvent sign){
            Player player = sign.getPlayer();
            if(sign.getLine(0).equalsIgnoreCase("example")){
                player.sendMessage(ChatColor.GOLD + "The sign has been changed");
                sign.setLine(0, motd);
            }
        }
}


Any luck?

SignListener (open) SignListener (close)

Code:

package com.tammcd.troubleinminecraft;

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.SignChangeEvent;

public class SignListener implements Listener {

    public static Main plugin;

    public SignListener(Main instance) {
        plugin = instance;
    }
    
    @EventHandler
    public void onSignCreate(SignChangeEvent sign) {
        Player player = sign.getPlayer();
        if (sign.getLine(0).equalsIgnoreCase("example")) {
            player.sendMessage(ChatColor.GOLD + "The sign has been changed");
            sign.setLine(0, plugin.getConfig().getString("motd"));
