Config help (a few questions)

I have a few questions about generating config files.

• Is it possible to create more than one yml file?
• If so, how can I create a yml file which has its name defined in a String var?

Thanks, also, I am quite a noob with this, only started a week ago but I'm learning fast

File configFile = new File(getDataFolder(), "fileName.yml");
FileConfiguration config = YamlConfiguration.loadConfiguration(configFile);

Thank-you! What about creating a file with a name stored in a var?

EDIT: Didn't seem to work for me. I put that exact code into a command and ran it. No file was made. I must be missing something obvious...

String fileName = "filename.yml";
File configFile = new File(getDataFolder(), fileName);

Put that in your main class:

Code:

private static final String CONFIG_NAME = "myconfig.yml";
 
private FileConfiguration config;
private File configFile;
 
public void reloadConfig() {
 
    if(configFile == null) {
        configFile = new File(getDataFolder(), CONFIG_NAME);
    }
 
    config = YamlConfiguration.loadConfiguration(configFile);
 
}
 
public FileConfiguration getConfig() {
 
    if(config == null) {
        this.reloadConfig();
    }
 
    return config;
 
}
 
public void saveConfig() {
 
    if(config == null || configFile == null) {
        return;
    }
 
    try {
        getConfig().save(configFile);
    } catch(IOException e) {
        getLogger().log(Level.SEVERE, "Could not save config to " + configFile, e);
    }
 
}

Now you can use the custom config as the normal config with getConfig(), reloadConfig() and saveConfig()

you gotta save it config.save(configFile);

YES! Thank-you so much! Also, how can I setup the default stuff. The tutorials all say to do this:

Code:java

 if(!.exists())
                {
                    cfg.addDefault("config.baserep", 1);
                    cfg.options().copyDefaults(true);
                    saveConfig();
                }

But your method is a bit different?

Nope. Same thing, just saveConfig is replaced with config.save(configFile)

Ok, I did this and also changed the cfg to config. But the only error left is on .exists - its asking me if I want to make a method named exists()

But if I removed the whole if line its fine...

if(file.exists()) {

You weren't checking if anything existed.

Brilliant. Any idea how to check if a file with that players name already exists and cancel the file generation?

Code:java

 
if file exists {
    cancel creation
    tellplayer(You are already activated)
}
 

Assuming the file name is the name of the player....

Player p = // Your player;

for (File f : getDataFolder().listFiles()) {
if (f.getName().equalsIgnoreCase(p.getName()) {
p.sendMessage("You are activated!");
}
}

Hmm, fine in terms of java... internal error in bukkit. I'm sure I must have implemented it wrong.

Code:java

String name = sender.getName();
 
            sender.sendMessage(ChatColor.RED + "You are set-up for reputation!");
 
            String fileName = name + ".yml";
 
            Player p = null;
 
                    for (File f : getDataFolder().listFiles()) {
                    if (f.getName().equalsIgnoreCase(p.getName())) {
                    p.sendMessage("You are already activated with reputation!");
                    }
                    }
 
              File configFile = new File(getDataFolder(), fileName);
                FileConfiguration config = YamlConfiguration.loadConfiguration(configFile);
                try {
                    if(configFile.exists())
                    {
                        config.addDefault("config.rep", 0);
                        config.options().copyDefaults(true);
                        config.save(configFile);                    }
                    config.save(configFile);
                } catch (IOException e) {
                    e.printStackTrace();
                }
 

Because p is null and you are trying to execute a method on a null object, thus you got an NPE. Assign Player p to sender, after running an instanceof Player and casting it properly.

Ok. More errors.


First Run of command: Fine, config file made but nothing in it! Get message: You are set-up for reputation! As expected.
Second run of command: The contents is added to the config file. Get message: You are set-up for reputation!
Third run of command: Nothing changes. Get message: You are set-up for reputation!

Here is a few points that need to be understood.
1. The object in memory is a copy of the file on disk when the object was created.
2. Changes to the object in memory are not reflected in the file unless saved.
3. Saves are manual.
