Deleting and regenerating a World?

Does anyone know how I should go about deleteing and generating a world?

I think this may work, not tested though (For deleting worlds):

Code:java

Bukkit.getServer().getWorld("world").getWorldFolder().delete();

Using this to create worlds:

Code:java

Bukkit.createWorld(new WorldCreator("world"));

 

You can't delete worlds from a plugin.
If you unload a world Bukkit still hangs on to some resources and you can't delete it.
You have to start an external script after the server is fully stopped.

 

tommycake50 How does Multiverse delete worlds? "/mvdelete <worldname>"

EDIT: tommycake50 Max_The_Link_Fan
Would this work for erasing a world?

Code:java

public void deleteWorld(World world) {
Bukkit.unloadWorld(world, false);
File folder = world.getWorldFolder();
if(!folder.isDirectory()) return;
for(File file : folder.listFiles()) {
file.delete();
}
folder.delete();
Bukkit.getWorlds().remove(world);
}

You know, there's been lots of long topics regarding unloading a world. Apparently unloadWorld() doesn't fully unload the world, making the folder not editable. I'm not sure if that's changed since..

 

The_Doctor_123 I wasn't aware of that. Hopefully it's been patched so that the world will completely unload. If the method I put above does not work then I will make a loop to go through all aspects of the world (Chunks, Entities, etc..) and unload / remove them individually so that the world can be deleted.

 

Then how would I go about after finishing my game, it stops the game. Kicks everyone, and creates a new world?

 

As tommycake50 said, you need an external script. every plugin that has world deleting as a feature as some kind of script that accomplishes this. And in order to do this automatically, you can make a script that is called when the game is completed, then shuts down the server, deletes the world files and restarts it. i believe you can do this within a .bat script. you could probably do it in python as well. but until worldUnload() gets fix you need a script. sorry.

 

rbrick Max_The_Link_Fan JRL1004 The_Doctor_123 tommycake50 It's possible to delete a world when the server is still running without using some kind of weird script, I have the code somewhere on my PC, I'll show it once i get on it

 

Don't use .bat, Most servers are run on linux so an sh script would be better.
A external JAR would be ideal though I guess.

 

There is only one issue and that is that you can't delete your main world. With main world i mean the world that is defined in the server.properties. I hope you don't mind that

Code:java

public void resetmap() {
 
    for (Player p : Bukkit.getOnlinePlayers()) {
        p.kickPlayer("Kick reason....");
    }
 
    if (Bukkit.unloadWorld("worldname", true)) {
        System.out.println("Unloaded world");
    } else {
        System.err.println("Couldn't unload world");
    } 
    if (delete(new File("worldname"))){
        System.out.println("Deleted world!");
        WorldCreator wc = new WorldCreator("worldname");
        wc.environment(Environment.NORMAL);
        wc.createWorld();
        Bukkit.reload();
    } else {
        System.err.println("Couldn't delete world");
    }
}
 
private boolean delete(File file) {
    if (file.isDirectory())
        for (File subfile : file.listFiles())
            if (!delete(subfile))
                return false;
    if (!file.delete())
        return false;
    return true;
}

I'm not sure if you really need Bukkit.reload(), i do Bukkit.reload() just to make sure that the world is loaded again.

 

tommycake50 hehe i know. i have it setup on my linux system to run .bat and .sh files...i just went with the one most people are familiar with.

 

If I can find the code we use on Minecade, I'll toss it at ya.

 

Aaaand bash is 10x as powerful.
(Why cant windows users just get MinGW).
