Multiple File Configuration for Players

Hey there,

I am having lots of difficulties with NullPointerExceptions and what not with retrieving data from multiple configuration files for each player. The files are created normally when the player first joins the server, but I have problems getting the right player file, and retrieving data from it.

Any suggestions/improvements?

The main SettingsManager

Code:java

public class SettingsManager
{
    public static File file;
    public static FileConfiguration config;
 
    public SettingsManager(String fileName)
    {
        file = new File(UnderCovern.getPlugin().getDataFolder(), fileName + ".yml");
 
        if (!file.exists())
        {
            try
            {
                file.createNewFile();
            }
            catch (Exception e)
            {
                UtilLogger.exception(e, "[SettingsManager] Could not create new file.");
            }
        }
 
        config = YamlConfiguration.loadConfiguration(file);
    }
 
...

It will create a new file for each player. Here is the implementation I follow on a PlayerJoinEvent.

Code:java

        new SettingsManager(player.getName());
 
        if (!(player.hasPlayedBefore()))
        {
            SettingsManager.getConfig().createSection(player.getName());
 
            SettingsManager.getConfig().createSection(player.getName() + ".Coins");
 
            SettingsManager.getConfig().set(player.getName() + ".Coins", "0");
 
            SettingsManager.getConfig().createSection(player.getName() + ".Rank");
 
            SettingsManager.getConfig().set(player.getName() + ".Rank", Rank.STARTER.getRankName());
 
            SettingsManager.save();
        }

And lastly, here is my difficulty. I do not know how to retrieve data.

Code:java

    public static String getRank(Player player)
    {
        if (plugin.getDataFolder().getName().contains(player.getName()))
        {
            return SettingsManager.getConfig().getString(player.getName() + ".Rank");
        }
 
        return null;
    }

 

Use uuids not playernames,
Can we see stacktraces?
Thanks.

 

I think you should change the last part to:

Code:java

 public static String getRank(Player player)
{
new SettingsManager(player.getName());
if (SettingManager.get(player.getName() + ".Rank")!=null)
{
return SettingsManager.getConfig().getString(player.getName() + ".Rank");
}
 
return null;
}

plugin.getDataFolder().getName()
Would return something like "/plugins/PLUGIN_NAME", and:
plugin.getDataFolder().getName().contains(player.getName())
would never be true.
