setDrops() on BlockBreakEvent?

Okay that really made me laugh. registerEvents(listener, plugin base)

Also thankyou so much @jasonwynn10 for explaining, constructive criticism is the best way to learn imo

 

Massive facepalms...

when attempting to register a class as a Listener in PocketMine, one must always implement the Listener Class and call the registerEvents() function. The reason it didn't work in your second attempt is because you didn't use any variables when you were registering the class. $this is the variable representation of the class. what you used $this->getServer()->getPluginManager()->registerEvents(listener, plugin base); are not variables or the proper inputs for the function.

It's good to see that you are attempting to learn. Keep it up, but I recommend posting i the facepalm section due to the nature of these small programming mistakes.

 

I think these are questions, but I want to learn:
1. What is a Listener in PMMP? When do I need to use it?

2. I don't understand what this part of the code means:
registerEvents($this, $this)

 

What is class Listener? Why do I need it or a plugin like this one? Does this have something to do with instanceof? If yes, what does that mean and do?

Plus, why $this, $this? Why do I need two of these '$this's? What does that exactly mean?

 

$this = if it's in a class, it's referred to the object that it's in

 

A double $this refers to the Listener and the PluginBase. The registerEvents require both the Listener and the PluginBase. If the Listener is in the PluginBase, both the Listener and the PluginBase will be $this. If your Listener is in a separated class, the first $this would be replaced by an instance of the Listener you want to register. (new ListenerName($this), $this)

 

Is this now correct? Still doesn't work!

PHP:

<?php

namespace pmmp\DropIt;

use pocketmine\event\block\BlockBreakEvent;
use pocketmine\plugin\PluginBase;
use pocketmine\Server;
use pocketmine\item\Item;
use pocketmine\block\Block;
use pocketmine\Player;
use pocketmine\inventory\Inventory;
use pocketmine\event\Listener;

class Main extends PluginBase implements Listener {

    $this->getServer()->getPluginManager()->registerEvents($this, $this);
  
    public function onBreak(BlockBreakEvent $event) {
        if($event->getBlock()->getId() === 14) {
            $drops = array();
            $drops[] = Item::get(Item::IRON_INGOT, 0, 1);
            $event->setDrops($drops);
        }
     }
}


I tried this here too, also didn't work:

PHP:

<?php

namespace pmmp\DropIt;

use pocketmine\event\block\BlockBreakEvent;
use pocketmine\plugin\PluginBase;
use pocketmine\Server;
use pocketmine\item\Item;
use pocketmine\block\Block;
use pocketmine\Player;
use pocketmine\inventory\Inventory;
use pocketmine\event\Listener;

class Main extends PluginBase implements Listener {

    public function onEnable() {
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
    }
    
    public function onBreak(BlockBreakEvent $event) {
        if($event->getBlock()->getId() === 14) {
            $drops = array();
            $drops[] = Item::get(Item::IRON_INGOT, 0, 1);
            $event->setDrops($drops);
        }
     }
}

 

I don't know... the console moves too fast for me to see.
But is there anything wrong in that code?

 

Looks like there are no errors. Is there something wrong in the code?

 

Try registering onDisable() maybe? As you're working with listeners

 

Like this?

PHP:

public function onDisable(CommandSender $sender) {
    $sender->sendMessage("DropIt turned off!");
}

 

No

Just like onEnable(), register the events.

 

This?

PHP:

public function onDisable() {
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
}


 

Finally, it works...
Question:
Can I do it like this too? Like @jasonwynn10 said?

PHP:

drops[] = new Item(155) // Gives you a Quartz Block as drop


Problem is, I cannot set how many Quartz Blocks it should drop...

 

Code:

$drops->setCount()
/* amount of drops goes in bracket */

 

Like this?

PHP:

$drops->setCount(3);
drops[] = new Item(155)
