double tap on block or a mob

i wanna make something like this: when player hit once - something happens , but when player hit twice something else happens . Is it possible , i need it for my new public shop plugin=)

PHP:

if(!isset($this->test[$player->getName()])){
$name = $player->getName();
$this->test[$name] = true;

//1st time

}else{
$name = $player->getName();
unset($this->test[$name]);

//2nd time

}


What if they tap it once and decide not to tap it again until later

PHP:

public function onTap(PlayerInteractEvent $event){ // Or EntityDamageEvent
   $first = false
   if(isset($this->test[$event->getPlayer()->getName()])){
      if(microtime() - $this->test[$event->getPlayer()->getName()] < 3) $first = true; // I think this should make 3 seconds
   } else {
      $first = true;
   }
   if($first)
     // First time
     $this->test[$player->getName()] = microtime();
   } else {
     // Second time
   }
}


For such precise time comparison, try using microtime(true) instead. time() will round the time to an integer.

Something new to me, thanks.
