Problems with setting location to the config

Hey guys, I m trying to make a Minigame game but I have issue setting Team locations in a specified arena.
My main class:

Code:

package me.grantis.arenas;

import org.bukkit.plugin.java.JavaPlugin;

public class MainClass extends JavaPlugin {
   
    private static MainClass inst;
   
    public void onEnable() {
        registerConfig();
        inst = this;
        ArenaManager.getManager().loadArenas();
       
        getCommand("create").setExecutor(new ArenaCommands());
        getCommand("remove").setExecutor(new ArenaCommands());
        getCommand("arena").setExecutor(new ArenaCommands());
       
    }
   
    public static MainClass getInst() {
        return inst;
    }
   
    public void registerConfig() {
       
        if(getConfig().isConfigurationSection("Arenas")) {
            return;
        }
       
        else {
            getConfig().createSection("Arenas");
            saveConfig();
            reloadConfig();
        }
       
    }
   
}

My Arena class:

Code:

package me.grantis.arenas;

import java.util.ArrayList;
import java.util.List;

import org.bukkit.Location;
import org.bukkit.entity.Player;

public class Arena {
   
    List<Player> players = new ArrayList<Player>();
   
    String name;
    private Location arenaLoc, blueSpawn, redSpawn;
   
    public Arena(String name, Location arenaLoc, Location blueSpawn, Location redSpawn) {
       
        this.name = name;
        this.arenaLoc = arenaLoc;
        this.blueSpawn = blueSpawn;
        this.redSpawn = redSpawn;
       
    }
   
    public List<Player> getPlayers() {
       
        return players;
       
    }
   
    public String getName() {
        return name;
       
    }
   
    public Location getArenaLoc() {
        return arenaLoc;
    }
   
    public Location getBlueSpawn() {
        return blueSpawn;
    }
   
    public Location getRedSpawn() {
        return redSpawn;
    }
   
    public void setBlueSpawn(Location l) {
        this.blueSpawn = l;
        MainClass.getInst().getConfig().set("Arenas." + name + ".blueSpawn", ArenaManager.getManager().serializeLoc(l));
        MainClass.getInst().saveConfig();
        MainClass.getInst().reloadConfig();
    }
   
    public void setRedSpawn(Location l) {
        this.redSpawn = l;
        MainClass.getInst().getConfig().set("Arenas." + name + ".redSpawn", ArenaManager.getManager().serializeLoc(l));
        MainClass.getInst().saveConfig();
        MainClass.getInst().reloadConfig();
    }
   
}

My ArenaManager class:

Code:

package me.grantis.arenas;

import java.util.ArrayList;

import org.bukkit.Bukkit;

            }
        }
        return null;
    }

    public Arena createArena(String name, Location arenaLoc, Location blueSpawn, Location redSpawn) {

        Arena a = new Arena(name, arenaLoc, blueSpawn, redSpawn);
        arenas.add(a);

        MainClass.getInst().getConfig().set("Arenas." + name + ".location", serializeLoc(arenaLoc));

        MainClass.getInst().saveConfig();
        MainClass.getInst().reloadConfig();

        }

        MainClass.getInst().saveConfig();
        MainClass.getInst().reloadConfig();

        return a;
    }


    public void loadArenas(){
        for(String name : MainClass.getInst().getConfig().getConfigurationSection("Arenas").getKeys(false)){


            Location arenaLoc = deserializeLoc(MainClass.getInst().getConfig().getString("Arenas." + name + ".location"));
            Location blueSpawn = null;
            Location redSpawn = null;

            if(MainClass.getInst().getConfig().getString("Arenas." + name + ".blueSpawn") == null) {
                return;
            }
           
            else {
                blueSpawn = deserializeLoc(MainClass.getInst().getConfig().getString("Arenas." + name + ".blueSpawn"));
            }

            if(MainClass.getInst().getConfig().getString("Arenas." + name + ".redSpawn") == null) {
                return;

            if(!arenas.contains(arena)){

    }

    public void removeArena(String name) {

        Arena a = getArena(name);
        if(a == null) {
            return;
        }

        arenas.remove(a);

        MainClass.getInst().getConfig().set("Arenas." + name + ".location", null);
        MainClass.getInst().saveConfig();
        MainClass.getInst().reloadConfig();
        MainClass.getInst().getConfig().set("Arenas." + name + ".blueSpawn", null);

        MainClass.getInst().saveConfig();
        MainClass.getInst().reloadConfig();

    }



    public String serializeLoc(Location l){
        return l.getWorld().getName()+","+l.getBlockX()+","+l.getBlockY()+","+l.getBlockZ();
    }
    public Location deserializeLoc(String s){
        String[] st = s.split(",");
        return new Location(Bukkit.getServer().getWorld(st[0]), Integer.parseInt(st[1]), Integer.parseInt(st[2]), Integer.parseInt(st[3]));
    }


}

My ArenaCommands class:

Code:

package me.grantis.arenas;

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

public class ArenaCommands implements CommandExecutor{

    Location arenaLoc, blueSpawn, redSpawn;

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {

        Player player = (Player) sender;

        if(commandLabel.equalsIgnoreCase("create")) {

            if(args[0] != null) {

                String name = args[0];
                arenaLoc = player.getLocation();
                ArenaManager.getManager().createArena(name, arenaLoc, blueSpawn, redSpawn);
                player.sendMessage(ChatColor.GREEN + "Arena created !");


            }


        }

        if(commandLabel.equalsIgnoreCase("arena")) {

            if(args[0] != null) {

                if(args[1].equalsIgnoreCase("bluespawn")) {

                    String name = args[0];
                    Arena a = ArenaManager.getManager().getArena(name);
                    a.setBlueSpawn(player.getLocation());
                    player.sendMessage(ChatColor.BLUE + "Blue spawn set !");



                }

                else if(args[1].equalsIgnoreCase("redspawn")) {

                    String name = args[0];
                    Arena a = ArenaManager.getManager().getArena(name);
                    a.setRedSpawn(player.getLocation());
                    player.sendMessage(ChatColor.RED + "Red spawn set !");


                }
            }


        }

        else if(commandLabel.equalsIgnoreCase("remove")) {

            if(args[0] != null) {

                ArenaManager.am.removeArena(args[0]);
                player.sendMessage(ChatColor.GREEN + "Arena removed !");

            }

        }

        return true;
    }

}

And I m having error in ArenaCommands class on lines:

Code:

a.setRedSpawn(player.getLocation());

Code:

a.setBlueSpawn(player.getLocation());

Can somebody fix that? If yes please show me the solution I really need this !
Thank you !

 

@JavaNaza without knowing what kind of error you get and better also the whole console error barely anyone will be able to help you!

 

The spawn location is saved to the config file of the plugin so, you have to get the player's x y and z and then to save it on config.yml! But first make them ints like:
Location loc = player.getLocation();
int x = loc.getBlockX();
int y = loc.getBlockY();
int z = loc.getBlockZ();
and then save them on config
