Instant Respawn

Hey, i want to have when a player odes to instantly respawn, with no screen. I've found this,

Code:java

        @EventHandler
        public void onPlayerDeath(PlayerDeathEvent e) {
          final Player p = (Player) e.getEntity();
                    new BukkitRunnable(){
                        public void run(){
                        try {
                        Object nmsPlayer = p.getClass().getMethod("getHandle").invoke(p);
                        Object packet = Class.forName("net.minecraft.server." + Bukkit.getServer().getClass().getPackage().getName().replace(".", ",").split(",")[3] + ".Packet205ClientCommand").newInstance();
                        packet.getClass().getField("a").set(packet, 1);
                        Object con = nmsPlayer.getClass().getField("playerConnection").get(nmsPlayer);
                        con.getClass().getMethod("a", packet.getClass()).invoke(con, packet);
                        } catch (Throwable e) {
                        e.printStackTrace();
                        }
                        }
                        }.runTaskLater(this, 2L);

but that seems to have changed in 1.7. What would be the Updated form of this?

 

Packet205ClientCommand has been changed to PacketPlayInClientCommand
You can find a list made by one of the DBO staff here: https://docs.google.com/spreadsheet...aU1RZUswZ2dqUFRpTTkyUEk1dXc&usp=sharing#gid=0

 

With this,

Code:java

        @EventHandler
        public void onPlayerDeath(PlayerDeathEvent e) {
          final Player p = (Player) e.getEntity();
                    new BukkitRunnable(){
                        public void run(){
                        try {
                        Object nmsPlayer = p.getClass().getMethod("getHandle").invoke(p);
                        Object packet = Class.forName("net.minecraft.server." + Bukkit.getServer().getClass().getPackage().getName().replace(".", ",").split(",")[3] + ".PacketPlayInClientCommand").newInstance();
                        packet.getClass().getField("a").set(packet, 1);
                        Object con = nmsPlayer.getClass().getField("playerConnection").get(nmsPlayer);
                        con.getClass().getMethod("a", packet.getClass()).invoke(con, packet);
                        } catch (Throwable e) {
                        e.printStackTrace();
                        }
                        }
                        }.runTaskLater(this, 2L);

It doesn't work and i get this error,

MrLizardDogMan A much simpler method than to go into packets is to just set the player's health to 20 a few ticks after they die. Works and is not that complicated. No method is perfect however, and it can contain bugs just as your method will have some as well. Just a suggestion.

 

spoljo666 Ok i implemented that, and nothing happens. I might have imported the wrong library, not sure

MrLizardDogMan

Code:java

        Player p = event.getEntity();
        try {
            Object nmsPlayer = p.getClass().getMethod("getHandle").invoke(p);
            Object packet = Class.forName(nmsPlayer.getClass().getPackage().getName() + ".PacketPlayInClientCommand").newInstance();
            Class<?> enumClass = Class.forName(nmsPlayer.getClass().getPackage().getName() + ".EnumClientCommand");
 
            for (Object ob : enumClass.getEnumConstants()) {
                if (ob.toString().equals("PERFORM_RESPAWN")) {
                    packet = packet.getClass().getConstructor(enumClass).newInstance(ob);
                }
            }
 
            Object con = nmsPlayer.getClass().getField("playerConnection").get(nmsPlayer);
            con.getClass().getMethod("a", packet.getClass()).invoke(con, packet);
        } catch (Throwable t) {
            t.printStackTrace();
        }

 

MrLizardDogMan You have to call that method somewhere (in the PlayerDeathEvent)

PHP:

        @EventHandler
        public void onPlayerDeath(PlayerDeathEvent event) {
            final Player player = event.getPlayer();
            Bukkit.getServer().getScheduler().runTaskLater(this, new BukkitRunnable() {
                public void run() {
                    forceRespawn(player);
                }
            }, 2L);
        }

 

Or.

Code:

@EventHandler
public void onDeathWithNoNMS(EntityDeathEvent event){
  //checks for player and nulls
  event.setCancelled(true);
  <playervar>.teleport(spot);

 

calebbfmv
That would break basically every plugin in existence

 

SuperOmegaCow
No it wouldn't, wait, it would? Doesn't for me.

 

MrLizardDogMan

Code:java

 @EventHandler (priority=EventPriority.HIGH)
public void onDeath(PlayerDeathEvent event)
{
if (event.getEntity() instanceof Player)
{
final Player player = event.getEntity(); //gets the player
final EntityPlayer ep = ((CraftPlayer) player).getHandle();
 
Bukkit.getScheduler().scheduleSyncDelayedTask(this, new Runnable() //delayed task
{
@Override
public void run() {
PacketPlayInClientCommand in = new PacketPlayInClientCommand(EnumClientCommand.PERFORM_RESPAWN); // Gets the packet class
ep.playerConnection.a(in);
}
}, 5L); //delay in ticks
}
}

Hope this helps! Make sure you add craftbukkit as an external jar!

 

You want it to work?

Try the following code:

Code:java

Bukkit.getScheduler().scheduleSyncDelayedTask(KitPVP.getInstance(), new Runnable(){
            public void run(){
                ((CraftPlayer)e.getEntity()).getHandle().playerConnection.a(new PacketPlayInClientCommand(EnumClientCommand.PERFORM_RESPAWN));
                Player player = e.getEntity();
                player.setFireTicks(0);
                    player.setFireTicks(0);

calebbfmv gj cancelling an event which doesn't implement Cancellable

 

This code is so flawed (You couldn't cancel it in the first place) it ruined mcpvp's gamemode smash. With this code the player can store items in their crafting space and they wouldn't lose them on death. For instant respawn this is what I use:

Code:java

 @EventHandler
public void onDeathEvent(PlayerDeathEvent event){
Player p = event.getEntity();
PacketPlayInClientCommand in = new PacketPlayInClientCommand(EnumClientCommand.PERFORM_RESPAWN); // Gets the packet class
EntityPlayer cPlayer = ((CraftPlayer)p).getHandle(); // Gets the EntityPlayer class
cPlayer.playerConnection.a(in); // Handles the rest of it
}

 

22vortex22 fireblast709 consider my code, it works, i've tested it before.

 

My code works too? I've used it multiple times.

 

ok lol, i just want you to consider it, don't push things too hardcore man
