if hit particle on block ?

Hi

PHP:

public function onHit(EntityDamageEvent $event){
$player = $event->getEntity();
$snowball = $event->getDamager();
if($player instanceof Player){
  if($event->getCause() == EntityDamageEvent::CAUSE_PROJECTILE){
  if($snowball instanceof FlameParticle){
$player->kill();
  }
  }
}
}

its not work .

Can you explain more what would you do?

How should a particle be a damage cause? It's not solid, which means that it will just go through you, and anyways it is not related to projectiles. Change "FlameParticle" to "Snowball"

A particle is not an entity. The animation of a particle will only affect what the client sees. It won't even affect any physics on server-side, client-side or even singleplayer. To the server, the particle flashing for a moment and lingering for a whole minute is the same.

this on damage player not hit block
this hit block code

PHP:

public function onTouch(PlayerInteractEvent $event){
      $player = $event->getPlayer();
      $block = $event->getBlock()->getId();
 
      if($block == 1){ // 1 this stone block id
   
        $player->getLevel->addParticle(new FlameParticle($player));
      }
    }
// use pocketmine\event\player\PlayerInteractEvent;
