Config not writing properly

Main:

Code:

package comParkourMain;

import java.util.logging.Logger;

import org.bukkit.Bukkit;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;

import commands.JoinCourse;

import events.PlaceSign;
import events.SignClick;

public class Parkour extends JavaPlugin {

    public static Parkour plugin;
  
    public void onEnable() {
        plugin = this;
        PluginDescriptionFile pdffile = getDescription();
        Logger logger = Logger.getLogger("Minecraft");
        logger.info(pdffile.getName() + " has been enabled! (V." + pdffile.getVersion() + ")");
      
        PluginManager pm = Bukkit.getPluginManager();
        pm.registerEvents(new PlaceSign(this), this);
        pm.registerEvents(new SignClick(this),this);
      
      
        getCommand("parkour").setExecutor(new JoinCourse());
      
        getConfig().options().copyDefaults(true);
        this.saveDefaultConfig();
    }
}

PlaceSignEvent:

Code:

package events;

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

import comParkourMain.Parkour;

public class PlaceSign implements Listener{
    public PlaceSign(Parkour plugin) {}
    
    @EventHandler
    public void onSignChange(SignChangeEvent e) {
            if (e.getLine(0).equalsIgnoreCase("[parkour]")) {
                e.getPlayer().sendMessage("Check");
                e.setLine(0, "§3[Parkour]");
                if(e.getLine(1).equalsIgnoreCase("")) {
                    e.setLine(1, "§4ERROR");
                    e.getPlayer().sendMessage(ChatColor.RED + "Please enter the name of the parkour course!");
                } else {
                    e.getPlayer().sendMessage(ChatColor.AQUA + "Added the Parkour course " + e.getLine(1));
                    Parkour.plugin.getConfig().set("course", e.getLine(1));
                    e.setLine(2, "§9Click to Join");
                }
              
              
              
            }
     }
}

Config:

course:
name:
startlocation:

 

@MrAserFiles
And whats your problem? What have you tried? Have you debugged? What is the line that is causing the problem? We need to know these things in order to help you.

 

@MrAserFiles listen to @Zombie_Striker, hes right.

Code:

Parkour.plugin.getConfig().set("course", e.getLine(1));

Anyway, you have to save the config after changing it.

 

I think it may have been literally not saving the config file xD
