Saving location to config.yml

I want to save a location to a config.yml file.

Code:

public Location getArenaLocation()
    {
        this.config = loadConfig();
        World world = (World) config.get("world");
        Double x = config.getDouble("x");
        Double y = config.getDouble("y");
        Double z = config.getDouble("z");
        return new Location(world, x, y, z);
    }
 
    public void setArenaLocation(Location loc)
    {
        this.config.set("world", loc.getWorld());
        this.config.set("x", loc.getX());
        this.config.set("y", loc.getY());
        this.config.set("z", loc.getZ());
    }

That's what I currently have.

Any ideas?

 

Code:java

//Setting world
config.set("world", loc.getWorld().getName());
 
//Getting world
World world = Bukkit.getWorld(config.getString("world"));

Code:

        this.config.set("world", loc.getWorld().getName());

boolean is your config variable null?

 

boolean maybe remove this code?
this.config = loadConfig();
However, I'm not sure...

 

No, its "world: changeMe"

 

What's the loadConfig() method? Are you putting this in the main class?

 

This isn't in the main class.

Code:

private YamlConfiguration loadConfig()
    {
        try
        {
            YamlConfiguration config = new YamlConfiguration();
            config.load(this.configFile);
            return config;
        }
        catch (Exception e)
        {
            System.out.println(ChatColor.RED + "[SingleShot] An error occured! Please delete your SingleShot folder and reload the Plugin!");
        }return null;
    }

Hey there, please could you give us all of your code? It will help us to further analyse the problem!

P.S. Our usernames

 

Just for further reference. I think, this was the problem:

Code:java

private YamlConfiguration loadConfig()
    {
        try
        {
            YamlConfiguration config = YamlConfiguration.load(this.configFile);
            return config;
        }
        catch (Exception e)
        {
            System.out.println(ChatColor.RED + "[SingleShot] An error occured! Please delete your SingleShot folder and reload the Plugin!");
        }return null;
    }
