Wierd bugs with multiWorld teleporting

Heres my code:

Code:

package com.Snowl.bukkit.exodusNether;

import java.util.List;

import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.World;
import org.bukkit.World.Environment;
import org.bukkit.entity.Player;
import org.bukkit.event.player.PlayerChatEvent;
import org.bukkit.event.player.PlayerListener;
import org.bukkit.event.player.PlayerMoveEvent;

/**
 * Handle events for all Player related events
 * @author Snowl
 */
public class exodusNetherPlayerListener extends PlayerListener {
    private final exodusNether plugin;
    exodusNether exodusNetherInstance;

    public exodusNetherPlayerListener(exodusNether instance) {
        plugin = instance;
    }
  
    @Override
    public void onPlayerCommand(PlayerChatEvent event) {
        String split = event.getMessage();
        String split1[] = split.split(" ");
            if (split.toLowerCase().startsWith("/goto")) {
                //List worlds = exodusNetherInstance.getServer().getWorlds();
                if (split.toLowerCase().equals("/goto list"))
                {
                    int index = 0;
                       while (index < plugin.getServer().getWorlds().size()) {
                    event.getPlayer().sendMessage(plugin.getServer().getWorlds().get(index).getName());
                    index++;
                       }
                }
                else
                {
                    int index = 0;
                       while (index < plugin.getServer().getWorlds().size()) {
                    if (plugin.getServer().getWorlds().get(index).getName().equalsIgnoreCase(split1[1]))
                    {
                        event.getPlayer().teleportTo(plugin.getServer().getWorlds().get(index).getSpawnLocation());
                    }
                    index = +1;
                       }
                }
            }
            if (split.toLowerCase().startsWith("/worldcreate")) {
                int index = 0;
                   while (index < plugin.getServer().getWorlds().size()) {
                if (plugin.getServer().getWorlds().get(index).getName().equalsIgnoreCase(split1[1]))
                {
                    break;
                }
                index = +1;
                   }
                   if (index == plugin.getServer().getWorlds().size())
                   {
                       plugin.getServer().createWorld(split1[1], Environment.NORMAL);
                   }
            }
      }
}

(Ignore the non yaml command)
when I create a new world, that works fine, but once I tp to the world, it seems that if I try and tp back to my old world, it never spawns? o.o and then /goto list provides two "world" instead of one "world" and one "testworld".
And once you restart the plugin doesn't find the extra world at all

Does anyone know why?

 

Try using index++ or index += 1 instead of index = +1 as that will cause index to be 1 all the time, which is not the intended behaviour.

 

Thanks, I dont know why I used the other one. I'll test it out now
