Code :

PHP:

    public function onCommand(CommandSender $sender, Command $cmd, $lbl, array $args):bool{
        if($cmd->getName() == "topfarm"){
            $item = Item::get(Item::STICK, 0, 1);
            $item->setCustomName("§r§7TopFarm MAGIC");
            $sender->getInventory()->addItem($item);
            $sender->sendMessage("§9[ §6MARCOS §9]§7 Varinha adiciona ao seu inventário");
        }
    }

public function onCommand(CommandSender $sender, Command $cmd, $lbl, array $args):bool{
if($cmd->getName() == "topfarm"){
$item = Item::get(Item::STICK, 0, 1);
$item->setCustomName("§r§7TopFarm MAGIC");
$sender->getInventory()->addItem($item);
$sender->sendMessage("§9[ §6MARCOS §9]§7 Varinha adiciona ao seu inventário");
}
}

 

Add a return true at the last line of the function

 

No, no and no.
return statement stops the execution of a function.
when onCommand is returned false, it sends the usage.

So, at the end return false, so if the if condition is not met it sends the usage.
After "$sender->sendMessage("§9[ §6MARCOS §9]§7 Varinha adiciona ao seu inventário");", add a return true.

 

PHP:

    public function onCommand(CommandSender $sender, Command $cmd, $lbl, array $args):bool{
        if($cmd->getName() == "topfarm"){
            $item = Item::get(Item::STICK, 0, 1);
            $item->setCustomName("§r§7TopFarm MAGIC");
            $sender->getInventory()->addItem($item);
            $sender->sendMessage("§9[ §6MARCOS §9]§7 Varinha adiciona ao seu inventário");
        }
        return true;
    } 

 

Read what I said, stop pasting code and you don’t understand.
