Clone level

Hello everyone. How to clone(duplicate) level with changing name of level. Sorry for my bad english...

Copy level folder and edit level.dat

This is method (not my, but I have permission), I use in my BW plugin:

PHP:

public function addWorld($worldname){
  $base = ($worldname . "_base");
    $source = Server::getInstance()->getDataPath() . "worlds/" . $base . "/";
  $dest = Server::getInstance()->getDataPath() . "worlds/" . $worldname . "/";
 $count = 0;
 if ($this->xcopy($source,$dest)){
  try {
     Server::getInstance()->loadLevel($worldname);
    $level = Server::getInstance()->getLevelByName($worldname);
 }
}
function xcopy($source, $dest, $permissions = 0755) {
  if (is_link ( $source )) {
     return symlink ( readlink ( $source ), $dest );
  }

 if (is_file ( $source )) {
  return copy ( $source, $dest );
 }
 if (! is_dir ( $dest )) {
  mkdir ( $dest, $permissions );
 }
  $dir = dir ( $source );
     while ( false !== $entry = $dir->read () ) {
 if ($entry == '.' || $entry == '..') {
continue;
  }
            $this->xcopy ( "$source/$entry", "$dest/$entry", $permissions );
}
 $dir->close ();
 return true;
}
    public function recurse_copy($src, $dst) {
  $dir = opendir ( $src );
  @mkdir ( $dst );
        while ( false !== ($file = readdir ( $dir )) ) {
            if (($file != '.') && ($file != '..')) {
                if (is_dir ( $src . '/' . $file )) {
                    recurse_copy ( $src . '/' . $file, $dst . '/' . $file );
} else {
                    copy ( $src . '/' . $file, $dst . '/' . $file );
   }
  }
 }
 closedir ( $dir );
}


PS: I rewrite a bit this method, so It can be laggy and bad. PS: This copy the level called $worldname."_base" to level $worldname

Copy is no-problem. But how to edit level.dat?

use ManyWorlds

LoL. This is plugin development. "_"

WoW, you have own BedWars plugin. I also. Now l do SW plugin. I copy level folder with other function.

Did you know ManyWorlds has Github repository you could go and look how aliyuli did that

I think, rename source level to name of dest level, copy it, and rename source level to back name.

Yes, i know, but ManyWorlds loads levels for name, not folder name \:

ManyWorlds has function to change name in level.dat from folder name

Thank you!

Server::getInstance() is bad practice, use $this->getServer() instead

I also use this one!

Why are you using both then?

Yes, I found out Server::getInstance() is bad. Like loads of starting PocketMine developers, I learned something by minecraftgenius. However, now, I don't use any methods of minecraftgenius. Reason: LAGGGGGGGS

Yes, good for you. he has the best ideas and also the laggy and buggy plugins.

Wow. JoeJo is back from his ban. yay! [Off topic:This post is off topic.]

I say, I use "$this->getServer()".
