Change item name through NBT

How can i change an item's name through nbt tags?

 

Here's how PocketMine does it. I honestly don't know why you would want to handle NBT when there is already a function for it, but that example should get you started.

 

Which function?

 

Item::setCustomName(), which I highlighted on the GitHub link.

 

Can I just ask you why you want to do this instead of using setCustomName()?

 

If a player sets custom name on an item by setcustomname() and puts in chest, it seems to be glitching like it disappears, could be due to lag.

 

Steps to reproduce issue? Just rename item with setCustomName and put in a chest?

 

But u will need 50+ players on server for lag

 

I have seen your other thread and your server runs 11GB Memory/RAM... This cannot be a lag related issue. I will reproduce the issue myself. If it persists, feel free to open an issue on GitHub @ the PocketMine resporitory which you can find here; https://github.com/pmmp/PocketMine-MP

 

Yea okay thanks

 

Honestly, why do you think would this solve "lag"? The only way to rename an item in Minecraft is by manipulation of nbt tags. Item::setCustomName() is just the better way. Don't reinvent the wheel.

 

Thats what almost every phone and car company in the world did.

 

Yes, however he isn't doing anything(that I know of) to make the wheel better. He is just doing what the setCustomName method already does. A better analogy would be driving a car with the convertible top down. It doesn't change the way the car functions, but it may cause you to have a bad time if it rains. If there are any NBT changes(Given what I've heard about the current NBT implementation, this is very possible), the setCustomName method in PMMP will most likely be updated to support those changes, possibly preventing you from having issues in your plugin.

 

PHP:

$item = Item::get(Item::BOW, 0, 1, NBT::parseJSON("{display:"));

is this laggy or setCustomName();?

 

Honestly, no idea why you want to do this when there is already a function for that, but

PHP:

$nbt = new CompoundTag("", [
  new CompoundTag("display", [
    new StringTag("Name", $customName)
  ])
]);
$item->setCompoundTag($nbt);
// or
Item::get($itemId, $itemDamage, $itemCount, NBT::parseJson("{display:{Name:'$customName'}}");

 

What function?
