Get player name in a world

I need to get the player'a name in a world what I did is

PHP:

$name = Server::getInstance()->getLevelByName("knockback")->getPlayers()->getName();

Error: "call to a member function getName() on array"
I've been searching on Google how to fix this but no luck

PHP:

public function onDeath(PlayerDeathEvent $ev){
  $return = Server::getInstance()->getLevelByName("spawn");
  foreach(Server::getInstance()->getLevelByName("knockback")->getPlayers() as $all){
 
   if(count($all) == 1){
  
    $name = Server::getInstance()->getLevelByName("knockback")->getPlayers()->getName();
    foreach($this->getServer()->getOnlinePlayers() as $onlineplayers){
                                        $onlineplayers->sendMessage("§b[KB]§e$name has won KB!");
                                                              }
                            $all->teleport($return->getSpawnLocation());
                      }
                      }
                      }
                      }


 

The error is self-explanatory. $level->getPlayers() returns an array of Players. How can you get a single name of a group of players? Even if there is only one player in a level, it will still return that name in an array.

 

PHP:

$name = Server::getInstance()->getLevelByName("knockback")->getPlayer()->getName();

Error: Call to undefined method pocketmine/level/level::getPlayer()
Sorry I'm new to this thing I usually get the sender name

 

How do I get it, when the player dies of fall damage or being pricked by a cactus will it find the player who last hit the dead player?

 

My KillCounter plugin has this implemented. The code isn't too neat but you can see it here: https://github.com/BlockHorizons/Ki...KillCounter/listeners/PlayerEventListener.php
Look for lastPlayerDamageCause

 

If the player fell or killed by a cactus but you hit the player before it happened will it still register as you who killed the player

 

Yes it will, as I mentioned. Look at the EntityDeathEvent where it checks if the death cause it NOT another entity.

 

Thanks I'll try this

 

PHP:

public function onDeath(PlayerDeathEvent $ev){
  $return = Server::getInstance()->getLevelByName("spawn");
  $lastPlayerAttacker = null;
  $entity = $ev->getPlayer();
  foreach(Server::getInstance()->getLevelByName("knockback")->getPlayers() as $all){
 
   if(count($all) == 1) {
    $cause = $entity->getLastDamageCause();
   if($cause !== EntityDamageEvent::CAUSE_ENTITY_ATTACK) {
    $lastPlayerAttacker = $this->getServer()->getPlayer($this->getLastPlayerAttacker($entity));
   if($lastPlayerAttacker !== null) {
          $name = $lastPlayerAttacker->getName();
    foreach($this->getServer()->getOnlinePlayers() as $onlineplayers){
                                        $onlineplayers->sendMessage("§b[KB]§e$name has won KB!");
                                                              }
                            $all->teleport($return->getSpawnLocation());
                      }
                      }
                      }
                      }
                      }

Dunno what I did wrong
Call to undefined method KnockBack\Main::getLastPlayerAttacker()

 

The error says exactly the issue you are having... You shouldn't need someone to tell you.
You have an undefined function in your class. That is a php issue, not something about PMMP API. Issues such as those should go to StackOverflow.

 

Yeah I'm noob at this, I'm still learning I just recognize a few errors by having the errors repeatedly

 

How do I get the instance of player death in a level
