How to rename a world folder name?

Hi
I need that someone tell me how to rename any world folder name because I really don't know xD
Something like this:

PHP:

case 'rename':
$folder = $this->getServer()->getDataPath() . "worlds/" . $args[0]; //maybe?

//and rename it like
rename($folder, $args[1]); 

I don't know how to do it

 

Hmm... I'm not sure, but I don't think the folder is the level name, I think "level.dat" is what saves the level name.

 

Yes I know but is there any way to rename the folder name but nope inside folder files? like /worlds/lobby change it to /worlds/test

 

Try this:

PHP:

$worlds = $this->getServer()->getDataPath() . 'worlds/';
$oldWorldName = 'old';
$newWorldName = 'new';
rename($worlds . $oldWorldName, $worlds .  $newWorldName);

 

Some functions use the world name in level.dat and some use the folder name (don't know which one uses which one of those <-- dat English xD)
This could possibly help for changing the level.dat values: https://github.com/Muirfield/ManyWorlds/blob/master/src/aliuly/manyworlds/MwLvDat.php

 

Go to folder worlds right click folder name click rename and rename it
Best method :d

 

WTF XD

 

xDD

 

In your server.properties file you can change this

Code:

level-name=world

 

Yes I know just I wanted to know if its possible to rename a folder name by commands

 

That's something completely off-topic.

The poster wants to know how to change the name of an existing world via a plugin.

Just the folder, or the value in level.dat, too?

 

Just the folder

 

okay i just had this same problem today i wanted to change a world name or level whatever i renamed the world folder Server-lobby i went into server properties and changed level to Server.properties and opened the level.dat with a text editer and changed the name to Server-Lobby and now when i shut my server down it says unloaded level " " as if i didn't name it :d

its the small things that are a pain in the butt
