Problems with sign tap

Hi,

my core plugin teleports the player to a certain world when he taps certain a sign.
Here is my problem: it spams the console with world not found when tapping a not-world sign.

Here is my code:

PHP:

 public function playerBlockTouch(PlayerInteractEvent $event){
  if($event->getBlock()->getID() == 323 || $event->getBlock()->getID() == 63 || $event->getBlock()->getID() == 68){
  $sign = $event->getPlayer()->getLevel()->getTile($event->getBlock());
  if(!($sign instanceof Sign)){
  return;
  }
  $sign = $sign->getText();
  $kpw = $sign[1];
  $this->getServer()->loadLevel($kpw);
  $player = $event->getPlayer();
  if($sign[0]=='[KitPVP]'){
  $event->getPlayer()->sendMessage("-> Joining KitPVP match.");
  $event->getPlayer()->teleport(new Position("885", "65", "-358", $this->getServer()->getLevelByName($kpw)));
  }


Try it:

PHP:

 public function playerBlockTouch(PlayerInteractEvent $event)
 {
    if($event->getBlock()->getID() == 323 || $event->getBlock()->getID() == 63 || $event->getBlock()->getID() == 68)
    {
        $player = $event->getPlayer();
        $sign = $player->getLevel()->getTile($event->getBlock()); // Why not just use the event bock and cast it to sign?
        if(!($sign instanceof Sign))
            return;
   
        $sign = $sign->getText();
        if($sign[0]=='[KitPVP]')
        {
            $kpw = $sign[1];
            $this->getServer()->loadLevel($kpw);
            $player->sendMessage("-> Joining KitPVP match.");
            $player->teleport(new Position(885, 65, -358, $this->getServer()->getLevelByName($kpw)));
        }
    }
 }

Xd. Block I'd 323.

Just hope @PEMapModder does not see that. And, BTW it is an Item ID, not a blocks...

Yeah none of these work...

Wall sign/ Standing sign ids are 63/68 (I don't know what id is wall and what id is standing)
