How can I save data in a YAML file?

So I have plugins on my server for an example Bedwars. and to make an arena you must select a region and then create the arena. I was wondering how to save data in like a file named "arenas.yml" and if someone can help me hook my plugin with WorldEdit that would be much appreciated.

Thanks in advance.

EDIT: If this helps I am trying to create a minigame plugin based on the minigame Wool Wars on munchymc.com. I am also inexperienced so please explain how your solution works thanks!

 

Are you looking for help with creating the yml file or how to save and load data from it?

 

How to save and load data from it @MightyOne

EDIT: What I'm trying to do is set positions for an "arena"

 

@Jakob de Guzman
To create a YAML file:

Code:Java

 
File file = new File(getDataFolder()+File.separator+"arenas.yml");
FileConfiguration config = YamlConfiguration.load(file);
if (!file.exists()) {
    file.createNewFile(); //This needs a try catch
}

To set something in the file:

Code:Java

config.set("Location.World", location.getWorld().getName());
config.set("Location.X", location.getX());
config.set("Location.Y", location.getY());
config.set("Location.Z", location.getZ());
//To remove something do 'config.set("Whatever.Path-Here", null)'
config.save(file); //This needs a try catch

To get something from the file:

Code:Java

config.getString("Whatever.Path-Here");
config.getInt("Path-To.Some.Integer-Here");
config.getLong(""); //etc

 

@KarimAKL I've seen this post before, I don't understand it and I do not know where it goes. Sorry as I said I am new

 

Maybe you can start showing some code. Where are you trying to implement a custom yml file? How does your Arena class look like? At which point exactly can we help you?

Create Command

Code:

package me.Proximitynow.WoolWars.Commands;

import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

import me.Proximitynow.WoolWars.Main;
import me.Proximitynow.WoolWars.utils.utils;

public class CreateCommand implements CommandExecutor    {

    private Main plugin;
   
    public CreateCommand(Main plugin) {
       
        this.plugin = plugin;
        plugin.getCommand("wwcreate").setExecutor(this);;
       
    }
   
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
       
        if (!(sender instanceof Player)) {
           
            sender.sendMessage("Only players can execute this command!");
            return true;
           
        }
       
        Player p = (Player) sender;
       
        if (p.hasPermission("ww.create")) {
       
            if (args.length == 0) {
           
                p.sendMessage(utils.chat(plugin.getConfig().getString("prefix") + " " + plugin.getConfig().getString("missingargs")));
               
            } else {
               
                p.sendMessage(utils.chat(plugin.getConfig().getString("prefix") + " &aArena &e" + args[0] + " &ahas been created!"));
               
                // Create an arena here and save in arenas.yml
               
            }
           
        return true;
       
        } else {
           
            p.sendMessage(utils.chat(plugin.getConfig().getString("prefix") + " " + plugin.getConfig().getString("noperms")));
           
        }
       
        return false;
       
    }
   
}

Delete Command:

Code:

package me.Proximitynow.WoolWars.Commands;

import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

import me.Proximitynow.WoolWars.Main;
import me.Proximitynow.WoolWars.utils.utils;

public class DeleteCommand implements CommandExecutor    {

    private Main plugin;
   
    public DeleteCommand(Main plugin) {
       
        this.plugin = plugin;
        plugin.getCommand("wwdelete").setExecutor(this);;
       
    }
   
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
       
        if (!(sender instanceof Player)) {
           
            sender.sendMessage("Only players can execute this command!");
            return true;
           
        }
       
        Player p = (Player) sender;
       
        if (p.hasPermission("ww.delete")) {
       
            if (args.length == 0) {
           
                p.sendMessage(utils.chat(plugin.getConfig().getString("prefix") + " " + plugin.getConfig().getString("missingargs")));
               
            } else {
               
                p.sendMessage(utils.chat(plugin.getConfig().getString("prefix") + " &aArena &e" + args[0] + " &ahas been deleted!"));
           
                //Delete arena with ID/NAME
               
            }
           
        return true;
       
        } else {
           
            p.sendMessage(utils.chat(plugin.getConfig().getString("prefix") + " " + plugin.getConfig().getString("noperms")));
           
        }
       
        return false;
       
    }
   
}

 

@Jakob de Guzman
In the CreateCommand class you can set the arena in the 'arenas.yml' file like this:

Code:Java

File file = new File(plugin.getDataFolder()+File.separator+"arenas.yml");
FileConfiguration config = YamlConfiguration.load(file);
config.set("Arenas."+args[0]+".World", p.getWorld().getName());
//etc
config.save(file); //Try catch for this line

Put that code at the comment you made saying "// Create an arena here and save in arenas.yml"
For the DeleteCommand just do this:

Code:Java

File file = new File(plugin.getDataFolder()+File.separator+"arenas.yml");
FileConfiguration config = YamlConfiguration.load(file);
config.set("Arenas."+args[0], null);
config.save(file); //Try catch for this line

That should set the arena to null (remove it)
Again, that code goes where you said "//Delete arena with ID/NAME"

EDIT: Also, create the 'arenas.yml' file in the onEnable() to create it on startup
EDIT2: My bad, it's not 'YamlConfiguration.load(file)' but 'YamlConfiguration.loadConfiguration(file)'

 

@KarimAKL where do i put the arenas.yml in the onEnbale do i do it like the saveDefaultConfig or...

EDIT: and with the create command when i use it, it says "The method load(File) is undefined for the type YamlConfiguration"

 

Yes, do it like the 'saveDefaultConfig()'

Yeah that was my bad, it's 'YamlConfiguration.loadConfiguration(file)'
