how can i add permission to player using addAttachment?

my try:

PHP:

public function onCommand(CommandSender $sender, Command $command, string $label, array $args): bool{
        if($command->getName() == "ok"){
            if(count($args) > 1){
                $player = $this->getServer()->getPlayer($args[0]);
                $perm = $args[1];
                $this->addAttachment($player, $perm, true);
            }else{
                $sender->sendMessage("/ok name perm");
            }
        }
        return true;
    }

 

Where is function addAttachment() defined?

 

PHP:

$player->addAttachment($plugin, $perm, true);

 

PHP:

/** @var Permission $permission **/
$attachment $player->addAttachment($pluginBase, $permission, true);
// or
$attachment = $ev->getplayer()->addAttachment($pluginBase);
$attachment->setPermission($permission, true);

just make sure you save the attachment for later use

 

what is $plugin?

 

Your main class

 

What if I'm doing this in my main class?

 

Then use $this
