Example - Giving a player an enchantment on their current item

Say we want to give a player an enchantment on the item that the player is currently holding. We will use the following command syntax:

/enchantitem <enchantment> <level>

Since most enchantment levels range between 1 and 5, we will also make use of the IntegerArgument to restrict the level of the enchantment by usng its range constructor.

new CommandAPICommand("enchantitem")
    .withArguments(new EnchantmentArgument("enchantment"))
    .withArguments(new IntegerArgument("level", 1, 5))
    .executesPlayer((player, args) -> {
        Enchantment enchantment = (Enchantment) args[0];
        int level = (int) args[1];
        
        //Add the enchantment
        player.getInventory().getItemInMainHand().addEnchantment(enchantment, level);
    })
    .register();
