Player hit by Particle

how to check if a particle (Duster) and presents in a player

 

$bool = $player->asPosition()->equals($particle->asPosition());

 

I can use if i want player die?

PHP:

if($player->asPosition()->equals($particle->asPosition()));
$player->setHealt(0);


 

PHP:

if($player->asPosition()->equals($particle->asPosition()))
    $player->kill();

 

It is very unlikely Position->equals(Position) will return true, as it has to be precisely the same position (float precisely). You could first round the Vector3 to even make it possible for this to work.

 

PHP:

public function onIneract(PlayerInteractEvent $ev) {
            $player = $ev->getPlayer();
            if ($ev->getItem()->getId() === 369) {
               
                $directonVector = $player->getDirectionVector();
               
                for ($i = 3; $i < 20; $i++) {
                    $pos = $directonVector->multiply($i)->add($player);
                   
                    if ($player->getLevel()->getBlockIdAt($pos->x, $pos->y, $pos->z) !== 0) {
                        return;
                    }
                   
                    $particle = new DustParticle($pos, 0, 0, 0);
                    $player->getLevel()->addParticle($particle);
                   
                    foreach ($player->getLevel()->getEntities() as $ent) {
                        if ($ent === $player) {
                            continue;
                        }
                        if (!isset($temp)) {
                            $temp = $ent;
                        }else{
                            if ($ent->distance($pos) < $temp->distance($pos)) {
                                $temp = $ent;
                            }
                        }
                    }
                    if (!isset($temp)){
                    }elseif ($temp->distance($pos) < 2) {
                        for ($a=4; $a<5; $a++) {
                            $par = new FlameParticle($pos);
                            $par->setComponents(
                                $pos->x + (self::random() * 2 - 1) * 3, 
                                $pos->y + 0.3, 
                                $pos->z + (self::random() * 2 - 1) * 3
                            );
                            $player->getLevel()->addParticle($par);
                            if($player->asPosition()->equals($particle->asPosition())){
                                $player->kill();
                            }
                        }
                        return;
                    }
                }
            }
        }
    }


 

You can't move a particle in Bedrock Edition, nor can you listen to any packets that hold particles' position. But you can do assumption physics and figure out the position of a moving particle. Particle->asVector3() or Particle->asPosition() will return the initial position of the particle. The position doesn't update like it does in entities. Because unlike entities, position of particles cannot be found through packets.

 

As I previously mentioned, checking for equality without rounding the 2 vectors is not going to work out for you.
