Solved I have a problem with plugin implementation...

Fatal error: Class com\MCBE\MCommand contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (pocketmine\command\PluginIdentifiableCommand::getPlugin) in /storage/emulated/0/PocketMine-MP/plugins/PVPHUD-7Wdev/src/com/MCBE/MCommand.php on line 20

PHP:

<?php
namespace com\MCBE;

//pmmp libs!
use pocketmine\command\PluginIdentifiableCommand;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\utils\CommandException;
use pocketmine\event\player\PlayerCommandPreprocessEvent;
use pocketmine\event\server\ServerCommandEvent;
use pocketmine\plugin\Plugin;
use pocketmine\utils\TextFormat as C;
use pocketmine\Player;
use pocketmine\event\player\PlayerQuitEvent as Disconnect;

//mine libs!
use com\MCBE\Main;
use com\MCBE\MTask;

class MCommand extends Command implements PluginIdentifiableCommand {

    private $command;

    public function __construct(Main $plugin)
      {
         $cmd = Main::$cfg->get('cmd');
         parent::__construct($cmd, "displays pvp hud!", "/" . $cmd, []);
         $this->setPermission("pvphud.command");
         $this->command = $plugin;
      }

    public function execute(CommandSender $sender, string $commandLabel, array $args)
      {
         if($sender instanceof Player)
          {
             $task = new MTask($this, $sender);
             $this->command->getServer()->getScheduler()->scheduleRepeatingTask(task, 40);
          } else
              {
                 //nothing ...
              }
      }
    
    public function onDisconnect(Disconnect $e)
      {
         $e->getPlayer()->cancelMTask();
      }
}
?>

 

You have to add this function:

PHP:

public function getPlugin() : Plugin{
    return $this->plugin;
}

As seen by the error above:

Hope this helped

 

I did this before and got an error, this func isn't returning Plugin

 

In your case, the property that references your plugin is command (which is a hella confusing name, I recommend going with plugin instead)

 

Also this didn't work, anyway I fixed the code it had many mistakes thank you
