Stop repeating task when arrow hits player or block

I have this function that makes it so when a player shoots an arrow particles follow the arrow. However, when the arrow hits a block or a player, it still continues the repeating task. Can someone help me, please?
My function:

PHP:

public function shootBow(EntityShootBowEvent $event){
        $arrow = $event->getProjectile();
        $player = $event->getEntity();
        if($player instanceof Player){
            $this->getScheduler()->scheduleRepeatingTask(new ClosureTask(function (int $currentTick) use ($player, $arrow) : void{
                if($arrow !== null){
                    $player->getLevel()->addParticle(new LavaParticle(new Vector3($arrow->getX(), $arrow->getY(), $arrow->getZ())));
                }
            }), 1);
        }
    }

 

i dont think this idea is that simple
you may need to use both 2 events ProjectileHitBlockEvent and ProjectileHitEntityEvent and the event in your code (or ProjectileLaunchEvent)

PHP:

public $saveId = [];
public function shootBow(EntityShootBowEvent $event){
        $arrow = $event->getProjectile();
        $player = $event->getEntity();
        if($player instanceof Player){
            $this->getScheduler()->scheduleRepeatingTask(new ClosureTask(function (int $currentTick) use ($player, $arrow,$saveId) : void{
                if($arrow !== null){
                    $player->getLevel()->addParticle(new LavaParticle(new Vector3($arrow->getX(), $arrow->getY(), $arrow->getZ())));
                    $saveId[$arrow->getSaveId()] = [$this->getTaskId()];
                }
            }), 1);
        }
}
public function onHitBlock(ProjectileHitBlockEvent $event){
        $entity = $event->getEntity()->getSaveId();
        if(array_key_exists($entity,$this-->saveId()){
           $this->getServer()->getScheduler()->cancelTask($this-->saveId()[$entity]);
        }
}

im not sure if that idea will gonna work but that what i think

 

I figured it out by using isFlaggedForDespawn
My current code:

PHP:

public function shootBow(EntityShootBowEvent $event){
        $arrow = $event->getProjectile();
        $player = $event->getEntity();
        $saveId = $this->saveId;
        if($player instanceof Player){
            $this->getScheduler()->scheduleRepeatingTask(new ClosureTask(function (int $currentTick) use ($player, $arrow, $saveId, $event) : void{
                if(!$arrow->isFlaggedForDespawn()){
                    $player->getLevel()->addParticle(new LavaParticle(new Vector3($arrow->getX(), $arrow->getY(), $arrow->getZ())));
                }
            }), 1);
        }
    }
   
    public function onHitBlock(ProjectileHitBlockEvent $event){
        $entity = $event->getEntity()->getSaveId();
        $event->getEntity()->flagForDespawn();
       
    }

It also works when the arrow hits a player, since it's flagged for despawn when it hits a player.

Edit: I don't know why an image is there, just ignore it.

 

A simpler way would be to create an entity extending arrow, set it as the projectile in EntityBowShootEvent, then have it spawn the particle while it's not flagged for despawn
