players online slapper

is there a command in slapper where i can make the player count appear with a floating text

 

Hmmm I know FlaotingParticle

PHP:

/** var $level Level **/
/** var $x, $y, $z Postion **/
/** var $server Server **/
$online = count($this->getServer()->getOnlinePlayers());
$max_online = $server->getMaxPlayer();
$level->addPraticle(new pocketmine\level\praticle\FloatingTextParticle(new pocketmine\math\Vector3($x, $y, $z),  "Player online\n$online/$max_online");

This code can't update number players real
use in Task
