Trying to delete then regenerate a world.

Hey everyone, I have been stuck on this for hours. I am trying to delete a world, regenerate the world, then tp all players to that world, but whenever I regenerate the world after deleting, I get this:

Code:

21:20:39 [INFO] World Created!

Then when I teleport to that world, I just start falling and it's just blue sky.

Here is my code:

Code:java

 
public boolean deleteWorld(String file) {
if(Bukkit.unloadWorld(file, false))
System.out.println("Unloaded World");
 
System.out.println("Deleting PvP World");
 
try {
FileUtils.deleteDirectory(new File(file + File.separator));
} catch (IOException e) {
e.printStackTrace();
}
 
if(!new File(file + File.separator).exists()) {
return true;
} else
return false;
}
 
public static void createWorld(String world)
{
System.out.println("Creating New World!");
Bukkit.createWorld(new WorldCreator(world).environment(Environment.NORMAL));
System.out.println("World Created!");
}
 

I call it like so:

Code:java

 
deleteWorld("pvpworld")
createWorld("pvpworld")
 

Can anyone find what I am doing wrong? :/

Bump?

Bump again? I'm really stuck on this?

Create world must be delayed because when you create the world the thread is still asleep...

 

Can you give me an example of how I would do that xTrollxDudex ? Sorry I don't really know what you mean.

 

You are causing the thread to sleep to long.

Code:

 Thread.sleep(2000);

 

Ah OK, thanks.

Hm, removed that whole

Code:java

 
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
 

bit, but it still gives the same error, no change whatsoever...

Why does the thread need to be slept? Show us all the classes involving this.
Anyway:

Code:java

<main class name> plugin;
public <this class's name>(<main class name> plugin){
        this.plugin = plugin;
}
deleteWorld("pvpworld");
Bukkit.getScheduler().scheduleSyncDelayedTask(plugin, new Runnable(){
        @Override
        public void run(){
                createWorld("pvpworld");
        }
}, 2001L)

 

xTrollxDudex this is my current code, top function is where I call it from, and that is just called from another function which is just a timer, which is called from onenable

Code:java

 
 
public void startGame() {
// Set max game length
maxGameTime = getConfig().getInt("General.Game.MaxGameLength");
 
// Set current game length
gameTime = 0;
 
for(Player p : Bukkit.getOnlinePlayers()) {
p.getInventory().clear();
p.getInventory().setHelmet(null);
p.getInventory().setChestplate(null);
p.getInventory().setLeggings(null);
p.getInventory().setBoots(null);
p.teleport(new Location(Bukkit.getWorld(pvpworld), Bukkit.getWorld(pvpworld).getSpawnLocation().getBlockX(), 128, Bukkit.getWorld(pvpworld).getSpawnLocation().getBlockZ()));
ignoreFallDamage.add(p.getName());
}
 
Timer fallTimer = new Timer();
fallTimer.schedule(new TimerTask() {
@Override
public void run() {
for(Player p : Bukkit.getOnlinePlayers()) {
ignoreFallDamage.remove(p.getName());
}
}
}, 6*1000);
 
// Start the game timer, this runs every 10 seconds.
gameTimer = new Timer();
gameTimer.schedule(new TimerTask() {
@Override
public void run() {
if(gameTime <= maxGameTime)
Bukkit.broadcastMessage(ChatColor.BLUE + "Time left: " + (maxGameTime-gameTime) + " seconds.");
gameTime += 10;
if(gameTime >= maxGameTime) {
// Teleport everyone to lobby world and announce winner.
for(Player p : Bukkit.getOnlinePlayers()) {
p.getInventory().clear();
p.getInventory().setHelmet(null);
p.getInventory().setChestplate(null);
p.getInventory().setLeggings(null);
p.getInventory().setBoots(null);
World world = Bukkit.getWorld(lobbyworld);
p.teleport(world.getSpawnLocation());
}
gameTimer.cancel();
inProgress = false;
readyGame(cooldownOnStartup);
deleteWorld(pvpworld);
createWorld(pvpworld);
}
 
}
}, 0, 10*1000);
 
}
 
public boolean deleteWorld(String file) {
if(Bukkit.unloadWorld(file, false))
System.out.println("Unloaded World");
 
System.out.println("Deleting PvP World");
 
try {
FileUtils.deleteDirectory(new File(file + File.separator));
} catch (IOException e) {
e.printStackTrace();
}
 
if(!new File(file + File.separator).exists()) {
return true;
} else
return false;
}
 
public static void createWorld(String world)
{
System.out.println("Creating New World!");
Bukkit.createWorld(new WorldCreator(world).environment(Environment.NORMAL));
System.out.println("World Created!");
}
 

 

_8Bit You need to check to make sure the world is deleted at line 53 like.

Code:

if (deleteWorld(pvpworld){
 
createWorld(pvpworld)
 
}

Idk if that will fix your problem though.

Chances are you need to tell bukkit to stop running updates on the world. Every time bukkit does an update it is called a 'tick', by 'ticking' a world you are just updating it. There is probably a way to unload a world from bukkit.

Have you tried just using world.regenerateChunk(x, y) to regen it rather then deleting the whole world?

EDIT: Eh. Found unloading a world: http://jd.bukkit.org/rb/doxygen/d4/...Server.html#aa37af379fe2d4f8dc9052c556d2723aa

 

I'll try world.regenerateChunk(), what would be the best way to loop through chunks in a 1000 block radius? Also, anyone know a way to change the seed?

 

Changing world seed: https://forums.bukkit.org/threads/is-there-a-way-to-modify-a-worlds-seed.80069/#post-1157843
Iterating through chunks:

Code:

for (int x = -32; x <= 32; x++) {
  for (int z = -32; z <= 32; z++) {
    world.regeneratechunk(x, z);
  }
}
