Override Item class

Hey, i have a new class named CItem.php
And i want to extend Item.php so i have CItem.php functions

I know you can do that with player class through $event->setPlayerClass(CPlayer::class);
But anyway with Items?

 

There's a large difference between PlayerCreationEvent and the ItemFactory class. As far as I know, when the server starts, the items are instantiated via the ItemFactory class at once, which means that every time that you use the function ItemFactory::get, or Item::get, an item that is already instantiated is being returned. In contrast, however, the Player class is not instantiated when the server starts, so, from my knowledge, you'd have to override that functions by the means of modifications. However, I do not know everything, so I may be wrong. Hope this helps

 

But why do you want to have a custom Item class?

 

if you want to override already existing function in item.php, it's not possible because pocketmine is mostly calling all functions and constants directly from Item.php

 

To add custom functions, such as $item->getWhateverIWant();

 

It isn't possible and there probably will never be a way to register a custom item class but you can create a masking class using reflections.

PHP:

class ItemMask{

    public function __construct(Item $item){
        $this->item = $item;
    }

    public function setId(int $id) : void{
        $property = new \ReflectionProperty(Item::class, "id");
        $property->setAccessible(true);
        $property->setValue($this->item, $id);
    }
}

/** @var Item $item */
$mask = new ItemMask($item);
$mask->setId(Item::BEDROCK);
var_dump($item->getId());//Item::BEDROCK


P.S. Changing an item's ID may cause unexpected behaviour because you aren't changing the Item class, just the item "graphic". This is just a demonstration.

 

Well, i have a custom enchant plugin, and i want to add a function $item->CE(CE instance);

 

Anybody else sense he's trying to re-invent the wheel?

 

Register a custom enchantment during startup then call Item->addEnchantment()?

 

I guess thats the only way then. I think they should add a method to override the class just like player class
