update slapper player status

I addes this in slapper

PHP:

$lobby = $this->getServer()->getLevelByName("world");
$lobbyp = count($lobby->getPlayers());
$name = str_replace("{color}", "§", str_replace("{line}", "\n",
str_replace("{lobby}", $lobbyp, trim(implode(" ", $args)))));


when I put {lobby} it shows how many players have in this world "0" but if I enter the world "0" does not change, how do I update every time someone enters this world?

 

You can either use EntityLevelChangeEvent or a task

 

I tried, but I can not get the Entity, not the error but also not the results.

 

Slapper is not intended for this use. Use a FloatingText that updates each ticks/ onLevelChange.

 

So what do I have to add and where?

 

Remove your code from Slapper plugin.
Create a new Plugin that spawns a FloatingText and saves his ID. Then each Ticks/LevelChange, check Number in Level and if different, update the ID Entity text

 

Could not use the aFloatingText itself?

 

There are already made plugins, you can use them
