Sign knockback

How can I check if a player is near a sign with "knockback" on the first line an give the player knockback?

 

Incorrect. You can call the Living::knockback() function to knock back a living entity.

 

PHP:

const RADIUS_SQ = 16;
/** @var Player $player */
foreach($player->getLevel()->getTiles() as $tile){
    if($tile instanceof Sign){
        if($player->distanceSquared($tile) <= self::RADIUS_SQ){
            $player->setMotion($tile->add($player)->normalize()->multiply(4));
        }
    }
}


 

This isn't working. Nothing happens and no errors

PHP:

public function onPlayerMove(PlayerMoveEvent $event) {

$player = $event->getPlayer();


//const RADIUS_SQ = 16;
foreach($player->getLevel()->getTiles() as $tile){
    if($tile instanceof Sign){
        if($player->distanceSquared($tile) <= 3){
        $player->sendMessage("Test");
            $player->setMotion($tile->add($player)->normalize()->multiply(4));
        }
    }
}
}

 

Oh huh. I didn't know that.
