deleting old world and creating new one

i need to delete an old world or at least delete the files inside the world folder and then i need to generate new files or a new world file that is new and has completely different terrain.
this happens after every game of my hg like game is done.
i currently found this:
Bukkit.getServer().unloadWorld("arena", (Boolean) null);
Bukkit.getServer().unloadWorld("arena_nether", (Boolean) null);
and then when a new game starts i do this:
if(Bukkit.getWorld("arena") == null){
Bukkit.getServer().createWorld(new WorldCreator("arena").environment(World.Environment.NORMAL));
Bukkit.getServer().createWorld(new WorldCreator("arena_nether").environment(World.Environment.NETHER));

oops. after i unload the world do i have to delete the file?

help!!!

To delete a world fully, you are going to need some form of recursion as File only has a method to delete one file at a time. There are some other libraries out there that does this already.

so how can i do this.

teej107
is this the way?

Code:

                Bukkit.getServer().unloadWorld("arena", (Boolean) true);
                Bukkit.getServer().unloadWorld("arena_nether", (Boolean) true);
                Bukkit.getWorld("arena").getWorldFolder().delete();
                Bukkit.getWorld("arena_nether").getWorldFolder().delete();

lrdemolition You need to delete all of the files/directories in each folder and sub-folder

 

lrdemolition

Code:

function delete(file)
{
    if file is directory
        foreach f in file // There is a method for getting all the files in a directory!
            delete(f) // Whooh! Recursion!
    delete(file)
}

This is basically what you do, but then written in pseudo :3

 

ohhh
ive seen this before
lemme go see if i can find it fireblast709 fireblast709 teej107

if (f.isDirectory()) {
for (File c : f.listFiles())
delete(c);

lrdemolition that is indeed the recursive part. Now add the last part, wrap it in a delete method, and you should be good to go.

 

@lrdemolition Close but you get the idea. Assuming delete(file) is your method, you also need to check if the file is a file or a directory. If it is a directory, use recursion (make sure you delete the folder too). If not, then just delete the file.
