getPlayers() isn't working :(

Hi,

I have another problem with my first plugin: getPlayers() does not work for me!

I am using this code

Code:

 $count = count($this->getServer()->getLevelByName("PVP")->getPlayers()); 

And every time I am using this my server crashes.

Error: Call to a member function getPlayers() on null
File: /TwinPVP/src/kjjnetwork/TwinPVP/Main
Line: 35
Type: E_ERROR

Am I doing something wrong?

Thanks at all for your patience with me

Because there is no such level called "PVP".

I'm sure there is. Command "/mw tp PVP" does also work.

Then it has not been loaded yet, and it only loads when you run /mv tp PVP.

PHP:

$this->getServer()->loadLevel("PVP");

You are my lifesaver!!!!
It finally WORKED!!!! Thank you very much!
