Solved Block break time

I'm trying to modify block break time for coal ore.

I overrode Block::getBreakTime(Item) to return 3 (i.e will take block 3 seconds to break).
That made the block crack animation last for 3 seconds but didn't break the block once the block break animation ended.

I've noticed Level::useBreakOn() being fired when the client sends InventoryTransactionEvent::USE_ITEM_ACTION_BREAK_BLOCK which isn't being sent once the modified block break animation ends.

Am i missing something? Is there any way to modify a block's break time?

PHP:

<?php
namespace spacename;

use pocketmine\block\CoalOre as PmCoalOre;

class CoalOre extends PmCoalOre{
    public function getBreakTime(Item $item) : float{
        return 3;
    }
}


 

Awesome, thanks!
