Unload World, Replace World, Load World

Hello, ( TOPIC NAME ).

Code:java

public void RestoreWorld() throws IOException {
for (Player h : Bukkit.getOnlinePlayers()) {
       Bukkit.broadcastMessage("xx");
       plugin.unload(h); // TELEPORT TO ANOTHER WORLD
        }
Bukkit.unloadWorld("BattleLance", false); // UNLOAD WORLD
restore = true;
final File CopyWorld = new File("BattleLance_COPY");
final File World = new File("BattleLance");
   Bukkit.getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable(){
int i = 21;
@Override
            public void run(){
i--;
if(i == 20) {
Bukkit.broadcastMessage(ChatColor.RED + "xx");
try {
copyFolder(CopyWorld,World); // COPY WORLD
} catch (IOException e) {
e.printStackTrace();
}
} else if(i == 10) {
Bukkit.broadcastMessage(ChatColor.RED + "xx");
Bukkit.createWorld(new WorldCreator("BattleLance")); // LOADWORLD
} else if(i == 5) {

}  else if(i == 0) {
restore = false;
for (Player h : Bukkit.getOnlinePlayers()) {
       Bukkit.broadcastMessage("xx");
       plugin.spawn(h);  // TELEPORT BACK TO SPAWN
       }
}
}
   }, 0L, 20L);

public static void copyFolder(File src, File dest) throws IOException{
 
   if(src.isDirectory()){
 
   //if directory not exists, create it
   if(!dest.exists()){
     dest.mkdir();
     System.out.println("Kopiruju svet " + src + "  do " + dest);
   }

   //Use bytes stream to support all file types
   InputStream in = new FileInputStream(src);
      OutputStream out = new FileOutputStream(dest); 
 
          byte[] buffer = new byte[1024];
 
          int length;
          //copy the file content in bytes 
          while ((length = in.read(buffer)) > 0){
        out.write(buffer, 0, length);
          }
 
          in.close();
          out.close();
          System.out.println("Zkopirovano z " + src + " do " + dest);
 
   }
   }

I destroy spawn. Use command which call RestoreWorld()
Teleport me to other world.
When teleport me back to spawn, all is always destroyed. Why ?
I Got this error: ( I don't know how this fix )!

The final error means you're trying to modify world files of a world that is still loaded (I believe).

 

But:

Code:

Bukkit.unloadWorld("BattleLance", false); // UNLOAD WORLD

 

unloadWorld doesn't remove all the world files if the server is still running because the files are still used. You can try unloading all of the chunks first, but I'm not sure. Still trying to figure out a way of my own too.

 

That little code snippet has actually worked for me before when I was attempting to reset a map.
I unloaded it then just loaded it again and it seemed to work fine. Could just be circumstantial but I dont know.

 

I changed:

Code:java

World w = Bukkit.getWorld("BattleLance");
for(Chunk c : w.getLoadedChunks())
c.unload(true, false);
 
Bukkit.unloadWorld(w, false);

But always throws error.

 

don't you have to move every player to another world before it will give up the ghost and actually remove all traces of it? Try running it from the console with nobody logged into the game.

 

Without login, restore is sucesfull, I login, destroy two block, Logout and Error...

I've run into this problem on some of my plugins as well. I haven't tested it yet, but this might be relevant.

 

infects someone else?

 

Unload fails if the world has players in it but still returns true.

heres my Unload or else!

Code:java

 
public boolean UnLoadWorld(String Name) {
World world =  plugin.getServer().getWorld(Name);
List<World> w = Bukkit.getServer().getWorlds();
Location loc = w.get(0).getSpawnLocation();
if (world != null){
plugin.info(plugin.getName(), world.getName() +" was not null");
 
 
for (Player p: world.getPlayers()){
p.teleport(loc);
}
 
 
 
 
if (plugin.getServer().unloadWorld(Name, true));
plugin.info(plugin.getName(),Name +" unloaded via Unload");
 
 
}else plugin.info(plugin.getName(),Name +" not loaded");
 
 
 
world =  plugin.getServer().getWorld(Name);
 
 
 
 
if (world != null){
 
plugin.info(plugin.getName(),Name +" Still Loaded, Stage 2 Evac!");
 
 
for (Player p: Bukkit.getServer().getOnlinePlayers()){
 
if (p.getWorld().equals(world)) p.kickPlayer("Dont be dead");
 
}
 
plugin.getServer().unloadWorld(Name, true);
}
 
 
world =  plugin.getServer().getWorld(Name);
 
 
 
return world == null;
 
 
}
