Trying to create my own /back command (not from death, but from a teleport)

Hey folks, I am trying to create a plugin that returns you back to your last known position after you /tp to a player.

I have an SMP server where my mods play legitimately, and they need to return to where they were before checking up on people with /tp.

Currently, it sometimes works, but mostly it just teleports you to the person you just ported to again.

Help is appreciated, thanks!

Code:java

package me.agent.BukkitArc;
 
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;
import java.util.logging.Logger;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.Location;
 
public class BukkitArc extends JavaPlugin {
 
    Logger l = Bukkit.getLogger();
    public tpListener entityListener = new tpListener(this);
    public static Map<UUID, Location> DL = new HashMap<UUID, Location>();
 
    HashMap<String, Location> playerHomes = new HashMap<String, Location>();
 
    @Override
    public void onEnable()
 
    {
        l.info("ArcaneSurvival has been enabled!");
        new ListenerClass(this);
        PluginManager pluginManager = getServer().getPluginManager();
        pluginManager.registerEvents(this.entityListener, this);
 
    }
 
    @Override
    public void onDisable()
 
    {
        l.info("Disabling ArcaneSurvival!");
        Bukkit.broadcastMessage(ChatColor.GREEN + "Reload complete.");
    }
 
    // tpback
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
      {
        if ((sender instanceof Player))
        {
          Player player = (Player)sender;
          UUID uuid = player.getUniqueId();
          if ((cmd.getName().equalsIgnoreCase("tpback")) && (sender.hasPermission("arcane.mod")))
          {
            player.teleport((Location)DL.get(uuid));
 
 
            return true;
          }
          sender.sendMessage("You cannot do that.");
          return true;
        }
        return true;
      }
 
 
 
 
 

And here is the listener:

Code:java

package me.agent.BukkitArc;
 
import java.util.UUID;
 
import org.bukkit.Location;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerTeleportEvent;
 
// tpback listener
 
public class tpListener
  implements Listener
{
  public tpListener(BukkitArc instance) {}
 
  @EventHandler(priority=EventPriority.NORMAL)
  public void onTeleport(PlayerTeleportEvent event)
  {
      UUID uuid = event.getPlayer().getUniqueId();
      Player player = event.getPlayer();
      Location loc = player.getLocation();
      BukkitArc.DL.put(uuid, loc);
  }
}
 

 

Moved to a more appropriate forum.

 

What happens when you debug the calls to your onTeleport method?

 

It is teleporting you to the spot you just teleported to because you have teleported to that spot multiple times. To see what I send a message to a player whenever they teleport. Idk why bukkit does this but the teleport event seems to be fired more than once. To counter act this simple check if the location they teleported too is either in another world or further away then 3 blocks before you set this location as their last location.

 

Forseth11 I don't have that problem. You probably have something else going on, or you registered the event twice.

 

On playerTeleportEvent, wich of the locations does getLocation returns? Have you tried to replace it with e.getFrom()?

 

If you have a command to teleport, and to teleport back you should...
Save the location in an arraylist when the player types the teleportcommand.
And if they do /back they will be teleported to the location in the arraylist. Simple as it is.

 

Then it wouldn't be compatible with other plugins. DarkRangerMC

 

Arg, then you just save it in the arraylist at the Teleport event...

 

Well it has seemed to happen to me in like 30 different plugins.

 

Forseth11 make a thread describing your problem, because I've never seen it happen.

 

Necrodoom It's not really a problem I always have just worked around it and btw it only seemed to happen when something was lagging and when you teleport you bounce a bit then you can move.

 

Well I'm frustrated at this point, either nothing you guys suggested worked or I just didn't understand it.

I've been googling and troubleshooting this thing for a few hours now, it's such a simple command but I can't seem to figure it out... Can somebody please walk me through this like I'm an idiot?

 

Erm.... Sorry... Could you replace your line registering your events with this one...

getServer().getPluginManager().registerEvents(new tpListener(this), this);
And see if that works?
