Player count on slapper

Hello, how to put the player count of an world on an slapper/npc?

 

I have the same question like yours

 

I found a code. It may help you:

PHP:

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

 

this is not working

 

That is working code
You just have to think about it

 

what exactly code? cuz not working on me?

 

[03:15:19] [Server thread/CRITICAL]: Error: "Call to undefined method slapper\entities\SlapperHuman::getServer()" (EXCEPTION) in "plugins/Slapper.phar/src/slapper/SlapperTrait" at line 83

i got this error i input this code

 

PHP:

"{CreativePlot}" => count($this->getServer()->getLevelByName("CreativePlot")->getPlayers());

this is my line 83

 

This code was fine for 2 years ago. Now I'm not interested in PMMP anymore.

 

help me for 1 sec pls?

 

PHP:

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

i input this and i got this error
[03:07:47] [Server thread/CRITICAL]: Error: "Call to undefined method slapper\entities\SlapperHuman::getServer()" (EXCEPTION) in "plugins/Slapper.phar/src/slapper/SlapperTrait" at line 84

[08:46:33] [Server thread/CRITICAL]: Error: "Call to undefined method slapper\entities\SlapperHuman::getServer()" (EXCEPTION) in "plugins/Slapper.phar/src/slapper/SlapperTrait" at line 87

how about this?

 

@RicardoMilos384's answer was wrong. Remove use pocketmine\Server; again and replace $this->getServer() with $player->getServer().

 

i got this code after i change and remove?
[18:01:01] [Server thread/CRITICAL]: Error: "Call to a member function getPlayers() on null" (EXCEPTION) in "plugins/Slapper.phar/src/slapper/SlapperTrait" at line 86

this is my line 86

PHP:

"{CreativePlot}" => count($player->getServer()->getLevelByName("CreativePlot")->getPlayers()),

 

You have to use valid level name, that means the level 'CreativePlot' must be generated and loaded

 

same error

[01:20:15] [Server thread/CRITICAL]: Error: "Call to a member function getPlayers() on null" (EXCEPTION) in "plugins/Slappcount.phar/src/slapper/SlapperTrait" at line 86

PHP:

"{PvP}" => count($player->getServer()->getLevelByName("PvP")->getPlayers()),

PS: i dont have PvP world

 

Then just use the level name that you have. Don't put name that will return null.

 

i cant understand? sorry how?
