cannot acess parent

Hi, I need help with the construction plugin. To console me writes error:

Code:

Notice: Trying to get property of non-object in /home/gamakk/GS/plugins/SurvivalGames/src/SurvivalGames/Config/SGConfig.php on line 28
[19:46:44] [Server thread/CRITICAL]: Error: "Cannot access parent:: when current class scope has no parent" (EXCEPTION) in "/SurvivalGames/src/SurvivalGames/Game/Arena/Arena" at line 29

SG\src\SG\Game\Arena\Arena:

PHP:

/** @var SurvivalGames  */
public $plugin;

/** @var  SGConfig */
public $config;

/*29*/ public function __construct(SurvivalGames $plugin) {
/*30*/    $this->plugin = $plugin;
/*31*/    $this->config = $this->plugin->loader->config;
/*32*/    parent::__construct($plugin);
}


SG\src\SG\Config\SGConfig:

PHP:

/*28*/public function __construct(Loader $loader) {
/*29*/    parent::__construct($loader);
/*30*/    $this->loader = $loader;
/*31*/    $this->arena = $this->loader->main->arena;
}


Thank you in advance .

 

You don't need to call the parent constructor (parent::__construct()) unless the parent has a constructor or you want to use the full functionality of the parent class (you wouldn't call the parent constructor from an abstract class, you'd do it from a class extending it).
