Plugin don't work

This Plugin dosn't work.

PHP:

<?php

use pocketmine\plugin\PluginBase;
use pocketmine\math\Vector3;
use pocketmine\level\particle\FlameParticle;
use pocketmine\scheduler\PluginTask;

class Main extends PluginBase {

    private $radius = 3;
    private $particles = 50;
    private $location, $level;
    private $sphere = false;

    public function __construct(Location &$location, bool $sphere)
    {
        $this->level = $location->getLevel();
        $this->location = &$location;
        $this->sphere = $sphere;
    }

    private static function getRandomVector() : Vector3
    {
        $x = 0; $y = 0; $z = 0;
        $x = (float)rand()/(float)getrandmax() * 2 - 1;
        $y = (float)rand()/(float)getrandmax() * 2 - 1;
        $z = (float)rand()/(float)getrandmax() * 2 - 1;
        $v = new Vector3($x, $y, $z);
        return $v->normalize();
    }

    public function onRun($tick) {
        for ($i = 0; $i < $this->particles; ++$i) {
            $vector = self::getRandomVector()->multiply($this->radius);
            if (!$this->sphere) {
                $vector->y = abs($vector->getY());
            }
            $this->level->addParticle(new FlameParticle($this->location->add($vector->x, $vector->y, $vector->z)));
            $this->location->add($vector->x, $vector->y, $vector->z);
        }
    }
}

 

Could you please please be more specific with your questions? 'Plugin don't work'+Code sounds like you want us to just fix everything and give it back to you. Include meaningful error messages, if any, or at least a description what doesn't work.

And from what i can see you did just copy random bits of code together and punch them into a Main class extending PluginBase and you expect it to work/be classified as a plugin? __construct is not called with anything for plugins and onRun() is belonging to a PluginTask.

 

This Plugin Create a sphere/hemisphere of particles but i dosn't work. It comes no Errors.

 

That's because nothing is ever called. Put the code you have in a Repeating Task and schedule that task in onEnable.
