Solved Event on Player $args[0]

I wanted to perform some event with the Player that was informed in $args[0], I tried to use this but it did not give...

public function execute(CommandSender $sender, $label, array $args){
if(!isset($args[0])){
$sender->sendMessage("Use: /test <player>");
return true;
}

$player = $this->pl->getServer()->getPlayer($args[0]);

if($args[0] == $player){
$player->sendMessage("TEST");
}
}

 

I'm edit if(isset($player))

my pl Run!

 

You don't need verify this, only do:

PHP:

 if(!is_null($player)){ # IF PLAYER IS ONLINE
       $player->sendMessage("TEST");
}else{
$sender->sendMessage("Player offline");
}


 

PHP:

if(!$player = $this->pl->getServer($args[0])){
//player not found 
return false;
}

//do what u want

 

PHP:

$user = $args[1];
$target = Server::getInstance()->getPlayer($user);
if ($target == null) {
$sender->sendMessage("§c{$user} is offline.");
} else {
//do what you want
}

that should work
