Renaming a block? client sided..?

Is it possible to rename a block? even if it has to be done in pocketmine source code directly? So for example when a player holds a sword instead if it saying "Diamond sword" above the hot bar it will sayy..."Smite tool" i know anvils will be able to do this one day but it dont work as of right now..

Currently not as long as i am concirned.
But i saw setCustomName($name) once.
If that doesn't work, have a look at my Firecracker plugin: https://github.com/ImagicalCorp/Firecracker/blob/master/src/thebigsmileXD/Firecracker/Main.php

This will atleast "rename" them when you select them in your hotbar.

Well thats one way around it thanks!

I will try the setcustomename quick.

Not working /: ill just use the popup for now.

Setting a custom display name and much more is possible using the new NBT support for items! Even the built-in give command has support for it. Look at this interesting gist from Shoghi.
The easiest way to use this in your plugin:

PHP:

$tags = NBT::parseJSON('{display:{Name:"My custom item name!"}}');
// $item is the Item object you want to change the name from
$item->setNamedTag($tags);

I didn't know these NBT tags myself until I found that gist of shoghi couple weeks ago. You can even lock chests! It's insane!

Woah..lots of cool stuff i never saw there. Is that from one of the new pocketmine dev builds? bc everytime i try to check the new dev builds the website is offline /:

Should it also be like this? it had a syntax error before and i know nothing about JSON.

PHP:

$tags = NBT::parseJSON("{display:{Name:"."My custom item name!"."}}");

No apparently it has been added in august, but I've never noticed. I just found a thread about it: http://forums.pocketmine.net/threads/how-to-use-namedtag.14538/#post-143725

Oh sorry yes the quotation marks should be escaped:

PHP:

$tags = NBT::parseJSON("{display:{Name:\"My custom item name!\"}}");

Thanks! ill try it out.

How does it come that noone knows it need JSON file format lol.

This is the first time ive ran into a situation where i needed JSON lol but that didnt work /: is the json format wrong? bc it works with commands but i cant get that to work..no error or anything and ive tried switching up the format a bit.

Please someone help me here..lol ive tried so many different formats for the $json..looked up tutorials..i cant get it to work /:

PHP:

$json = '{"display":{"Name":"§r§6§lMy custom name!"}}';
                var_dump(NBT::parseJSON($json));


Code:

class pocketmine\nbt\tag\Compound#22291 (3) {
  protected $__name =>
  string(0) ""
  protected $value =>
  NULL
  public $"display" =>
  class pocketmine\nbt\tag\Compound#25251 (3) {
    protected $__name =>
    string(9) ""display""
    protected $value =>
    NULL
    public $"Name" =>
    class pocketmine\nbt\tag\String#25253 (2) {
      protected $__name =>
      string(6) ""Name""
      protected $value =>
      string(25) "§r§6§lMy custom name!"
    }
  }
}

Just parsed it into that.. seems alright

OHHMERRGRRD...i have to remove the item then clone the new "named one" and re add it to their inventory -_- alllll that head ache...will clone cause memory leaks? i hear it will..i will use the pm function to check if it has a custom name before adding it again tho.

Also had to move the string to a txt file..no idea why..but it works lol

Actually, most of the Inventory methods clone the items that got from parameters and return cloned Item instances.

CustomName
Thats what you want, not name

I dont get what you mean? isn't a custom name anything different than the real name? lol i just had to remove the old item and add the new one with the custom name..

PHP:

if($item->getId() === Block::SPONGE)
        {
            if($item->hasCustomName())
            {
                return;
            }
            $data = file_get_contents($this->getPlugin()->getDataFolder()."Sponge.txt");
            $tags = NBT::parseJSON($data);
            $player->getInventory()->removeItem($item);
            $items = $item->setNamedTag($tags);
           
            if($player->getInventory()->getItemInHand() !== Item::get(0))
            {
                $player->getInventory()->addItem(clone $items);
                return;
            }
                $player->getInventory()->setItemInHand(clone $items);
                return;
           
        }
