Disable autosaving of a world.

Here is what my friend used:

PHP:

$this->getServer()->getLevelByName("WorldName")->setAutoSave(false);

Here is the error:

Code:

Error: "Call to a member function setAutoSave() on null" (EXCEPTION) in "SkyWars/src/skywars/arena" at line 143

The line 143 is this line

 

Level with the name "WorldName" doesn't exist... or maybe that isn't the folder name (the level's folder name can differ from the level's name and multiple levels can have the same name but not the same folder name).

 

Ok, so the error isn't here. I will let you know when I fix this.
