Nullpointerexception with teleportation

Hi, i created an homes systemb but, when i'm teleporting the player to his home, i'm getting an error in my console:

Code:

package fr.Spadax.Commands;

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

import fr.Spadax.YTool.YTool;

public class Home implements CommandExecutor
{

    YTool pl;
  
    public Home(YTool pl) {this.pl = pl;}

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, final String[] args)
    {  
        if(sender instanceof Player)
        {
            Player p = (Player) sender;
          
            if(args.length == 0)
            {
                p.sendMessage("§8> §CBonne commande: /home <nom> ! (Fais /homes pour voir la liste de tes homes !)");
                return true;
            }
          
            if(pl.homes.containsKey(p.getName().toLowerCase()+";"+args[0].toLowerCase()) && args.length == 1)
            {
                p.playSound(p.getLocation(), Sound.ENTITY_ENDERMEN_TELEPORT, 1, 1);
                p.getWorld().spawnParticle(Particle.DRAGON_BREATH, p.getLocation(), 30, 1, 1, 1, 0.01, null);
                p.sendMessage("§8> §ATu as téléporté au home : §F"+args[0].toLowerCase()+" §A!");
                p.teleport(pl.homes.get(p.getName().toLowerCase()+";"+args[0].toLowerCase()));
            }else p.sendMessage("§8> §CCet home n'existe pas ! (/homes ou /sethome)");
          
          
        }else sender.sendMessage("> Tu dois executer cette commande en tant que joueur !");
      
        return false;
    }

}

My error is displaying to give me the line 37 (p.teleport(...)) and to teleport the player, i'm getting the location in a hashmap. I don't understand why i'm getting that error beacause i'm checking if my hashmap (pl.homes) contains my location. Thanks for your help and sorry for my english !

@ipodtouch0218

 

Erm, two things that I think are right...

In the p.teleport the location must be provided, not a name. Not sure how you have the running, but p.teleport requires a location.

You should put more than just that class, as it would make it easier on us

 

@EscapeMC My hashmap is <String,Location>

@timtower But i'm checking no ? whith my pl.homes.containsKey() !

 

Mmm, that makes sense.

Do note though, @Spadax , that it is pointing to line 43, which is return false;
Look into that

 

@EscapeMC the line 43 is like the 38 beacause i added a messages after.

Code:

public void setUpHomes()
    {
        FileConfiguration cgs;
        File folder = new File(getDataFolder()+"/Players");
        for(File f : folder.listFiles())
        {
            int i = 0;
            cgs = YamlConfiguration.loadConfiguration(f);
            if(cgs.contains(f.getName().replace(".yml", "")+".Homes"))
            {
                ConfigurationSection cs = cgs.getConfigurationSection(f.getName().replace(".yml", "")+".Homes");
                for(String home : cs.getKeys(false))
                {
                    i++;
                    String[] part = cs.getString(home).split(";");
                    homes.put(f.getName().replace(".yml", "").toLowerCase()+";"+home.toLowerCase(), new Location(Bukkit.getWorld(part[0]), Double.valueOf(part[1]), Double.valueOf(part[2]), Double.valueOf(part[3]), Integer.parseInt(part[4]), Integer.parseInt(part[5])));
                }
            }
            homenb.put(f.getName().replace(".yml", ""), i);
        }
       
        if(getConfig().getStringList("Limite Homes") == null)
        {
            getConfig().set("Limite Homes", Arrays.asList(new String[] {"ytool.home;1"}));
            saveConfig();
        }
        for(String perm : getConfig().getStringList("Limite Homes"))
        {
            homelimit.add(perm);
        }
    }
