Get Entities in a certain area.

Let's say, I have an area -

PHP:

$x = [100,200];
$z = [300,400];


How do I get the Entities within this area? I do know how to check whether a player is in the area - that is by using events.

I'm trying to count the Entities in this area and display it in a FloatingTextParticle.

 

tried this (ps: i don't tested)

PHP:

$entities = 0;

foreach($level->getEntities() as $ent){
    if($this->isInSide($ent)){ // check if entity is in area
        $entities++;
    }
}


 

I don't think that'll work. But you might have helped me there! This might work:

PHP:

<?php

$lvl = Server::getInstance()->getDefaultLevel();
$ents = $lvl->getEntities();
foreach ($ents as $ent) {
$x = $ent->getX();
$z = $ent->getZ();
$xx = [100,200];
$zz = [300,400];
if ($x() >= min($xx) && $x() <= max($xx) && $z >= min($zz) && $z <= max($zz)) {
//How can I count the number of Entities INSIDE this region?
//doing count($ent); would return 1, right?
}
}
?>

 

PHP:

public (int) $counter = 0;

If ($ent instanceof \pocketmine\Player) {
  while ($this->counter = count($ent)) {
    $this->counter++;
  }
}
Echo "Entities in the region: ".$this->counter;


Would this work SOF3? Thanks for helping me

 

look this:

PHP:

$entities = 0;
foreach($level->getEntities() as $ent){
    $entities++; // its is same that: $entities = $entities+1;
}
