Block Water

How to query if you are currently in water

 

Getblock at player's position

 

And what is the listener for that?

 

There is no listener, you can call that from anywhere as long as you know the player's level
If you want to know when the player enters water, you should use a task to check

 

And how do you do that!?

 

PHP:

$this->getScheduler()->scheduleRepeatingTask(new class () extends \pocketmine\scheduler\Task{
   public function onRun(int $currentTick) : void{
      foreach(\pocketmine\Server::getInstance()->getOnlinePlayers() as $player){
         if($player->getLevel()->getBlock($player) instanceof Water){
            //do stuff
         }
      }
   }
}, 1);


 

PHP:

public function onMove(PlayerMoveEvent $event){
     if($event->getPlayer()->isUnderWater()){
         // code
     }
}

 

P.S. isUnderwater = player's eye height is under water.
Player can still have their feet in water but isUnderwater will return false
