How to Restore a world

How can i restore a world in the new API?

In the old api if i remember was,

PHP:

  $this->restoreWorld();


What for the new API?

In old API, $this->blah() only exists when you declare

PHP:

public function blah(){
}


in your script.

In the new?
How to restore?

Where did you find that restore world function?

Maybe its a bit old

No. You have to write the restore world function yourself, in old API or new API. In whatever plugin you found that function, you should look at the function restoreWorld() in that plugin instead (search "function restoreWorld(").

Yes but u can save the world in a config
And then delete it and use the saved one
(How do u delete it?)
$this->saveWorld();?
$this->delete world();?

you're not really helping, he want to RESTORE it, not load it and delete and reload .-.

Oh restore meaning delete or like that backup plugin

Yes, restore or rollback, not reload.

And saving in a config is terrible. It will spend ages.

P.S. Off-topic: talking of spending ages, today at school I wrote a calculator program that calculates 1 / i + 2 / i^2 + ... + 1000 / i^1000, but since Casio calculators don't support i^1000 and they don't have the modular arithmetic operator, I had to do a loop to Lbl1:B×i→B:1M+:M≤1000=>Goto 1: to calculate i^199 nd it still hasn't finished calculating after I got back from lunch -_- xD (the bad ending of cheaters )
