Teleport when spawned

What should I do to get a player to teleport a specific place after they die?

 

you want to either set the spawn location in PlayerRespawnEvent or schedule a task inside the PlayerRespawnEvent 1 tick later, teleporting them

 

Last time I tried that I did that I got an error. what should be the code with schedule a syncdelayed task

 

http://wiki.bukkit.org/Scheduler_Programming
Btw what error?

 

it couldnt pass the the event

whats wrong here?

Code:

  @EventHandler
    public void onPlayerRespawn(PlayerRespawnEvent event){
        Player p = event.getPlayer();
        Bukkit.getServer().getScheduler().scheduleSyncDelayedTask((Plugin) this, new Runnable() {
            @Override
            public void run() {
                event.getPlayer().teleport(arena1);
            }
           
        }, 1L);
        }
    }

I ment the stacktrace

Don't cast your Listener to Plugin, use an instance of the main class

 

Code:

/*@EventHandler
    public void onPlayerRespawn(final PlayerRespawnEvent event)  {
        Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable(){
 
            public void run(){   
                if (joined.contains(event.getPlayer())) {
                    event.getPlayer().teleport(arena1);
                } else {
                    event.getPlayer().teleport(Lobby);
                }
            }
        }, 10L);
 
    }*/

I still dont seem to figure it out

 

you should pass along an instance of the main class where you initialize the listener class, and use that instead of 'this'

 

I'm kinda new to coding so I'm not entirely sure how to do that :/

 

Code:java

private <main class> plugin;
public <other class>(<main class> plugin)
{
    this.plugin = plugin;
}

This is a basic snippet in Java. This way, you can use the instance of the main class (the one used to call onEnable() and onDisable()) in other classes (like Listeners and CommandExecutors). Now in the main class, you would create them like

Code:java

new <other class>(this);

Where you replace <main class> with your main class, and <other class> with any other class you use.

Btw 'this' is used to point to the current instance you are calling the method/constructor with. So if you use 'this' in the onEnable() method, it is the same instance as Bukkit uses, the same value retrieved by Bukkit.getPluginManager().getPlugin("name here");

 

Nice, thank you

Thats really messy, I can't even read some of it

 

Poppi you teleport a player to null somewhere, or a non-existant world

 

You first have to check if the player exists or not for them to teleport

Code:

if(player == null){
//Player does not exist
} else {
//Player Exists
}

 

I fixed it. apparently the server lagged and it wasnt registering that the player was there before after a few seconds...

what should I do to make it so the player is registered the instance they join, like updating it.
I unfortunately dont know what to update on that event

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

If your talking about when they join the server use

Code:

public void onPlayerJoin(PlayerJoinEvent event){
//Your code here
}

Oh you already used it

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

yes I have onPlayerJoin. My question is that my error when I use /join only fixes if I reload the server which is useless to do every time someone logs on.

 

can you show me the command code as i might be able to help you

 

Code:

public boolean onCommand(CommandSender sender, Command cmd,
            String commandLabel, String[] args) {
        if (commandLabel.equalsIgnoreCase("join")) {
            if (sender == null) {
               
            } else {
                if (sender instanceof Player) {
                    if (!(joined.contains(sender))) {
 
                        Player p = (Player) sender;
                        p.teleport(arena1);
                        PlayerInventory inv = p.getInventory();
                        inv.clear();
                        inv.setHelmet(new ItemStack(Material.LEATHER_HELMET));
                        inv.setChestplate(new ItemStack(
                                Material.CHAINMAIL_CHESTPLATE));
                        inv.setLeggings(new ItemStack(
                                Material.CHAINMAIL_LEGGINGS));
                        inv.setBoots(new ItemStack(Material.GOLD_BOOTS));
                        ((Player) sender).getInventory().addItem(
                                new ItemStack(Material.STONE_SWORD));
                        joined.add(p);
 
                    } else if (joined.contains(sender)) {
                        sender.sendMessage(ChatColor.DARK_AQUA
                                + "You are already in a game!");
                        sender.sendMessage(ChatColor.DARK_AQUA + "Type "
                                + ChatColor.AQUA + "/leave"
                                + ChatColor.DARK_AQUA + " in chat to leave!");
 
                    }
                } else {
                    sender.sendMessage(ChatColor.RED + "ONLY FOR PLAYERS!");
                }

 

Just the /join command code not the whole class file

 

that is the /join command

 

Ok so i will put a simpler code in for you that will work, As i developed a plugin slightly different to yours

Here

Code:

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
Player p = (Player) sender
if(commandLabel.equalsIgnoreCase("join")){
p.teleport(arena1);
p.getInventory().setHelmet(new ItemStack(Material.LEATHER_HELMET, 1));
p.getInventory().setChestplate(new ItemStack(Material.CHAINMAIL_CHESTPLATE, 1));
p.getInventory().setLeggings(new ItemStack(Material.CHAINMAIL_LEGGINGS, 1));
p.getInventory().setBoots(new ItemStack(Material.GOLD_BOOTS, 1));
p.getInventory().addItem(new ItemStack(Material.STONE_SWORD, 1));

Thats for the adding stuff in the inventory



EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

What I also do is adding them to an arraylist and checking if they are in it or not. my problem is that for some reason the player is null until I reload the server

 

well try removing this and not the code

Code:

if(player == null){
 
} else {
 
}

/\
|
Remove that and try it and see what error you get

Then post the error from your server log onto here if you get an error

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

I found the cause of the error. apparently I have to reload the server once before the plugin actully works correctly. that isnt dependent on if there is players online or not

 

:|

Poppi so are you ok?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Yeah, I seem to have figured out the errors even though I dont see why it must reload before working but I guess it isnt a huge issue

 

May i test it? If its ok with you

What version of bukkit are you using
