Crate Plugin - My First EVER plugin

Hello, I've made a start on a Crate plugin at the moment I'm working on the recievement of a crate key.
Questions)
How to use the items add id setup?
How to name a custom item?
And how to use a $ parentheses that will be dependent on what argument is stated in the comman eg. /Crate common (gives common key) /crate rare etc.

Funny enough I am using notepad++. Those pictures were when I was trying to test it on a server.pro thing, I couldn't find the latest pocketmine version to test it on, so I alternatively used a cheap option. but I'll have a look at upgrading to brackets.io.

Cheers,

 

PHP:

$item = Item::get(Id, damage, count);
$player->getInventory()->addItem($item);
One Line
$player->getInventory()->addItem(Item::get(Id, Damage, Count));

$item = Item::get(Id, damage, count);
$item->setCustomName("string");
$player->getInventory()->addItem($item);
One Line
$player->getInventory()->addItem(Item::get(Id, damage, count)->setCustomName("string"));

just incase your new to the PMMP API https://github.com/pmmp/PocketMine-MP/blob/master/src/pocketmine/item/Item.php

also remember to add \pocketmine\item\Item

 

And afterwards I can use $item and in game it should display as the custom name?

 

the item will not display the customname until you add the custom name
