CompoundTag not supported

Hi, what's wrong with my code, does not the compound tag seem to work?

PHP:

    public function getItemTier($id, $meta, $tier) : Item{
        $block = new Item($id, $meta);
        $nbt = $block->getNamedTag() ?? new CompoundTag("", []);
        $nbt->tier = new StringTag("tier", $tier);
        $block->setCompoundTag($nbt);
        return $block;
    }

 

Not sure this will fix it but try

PHP:

  public function getItemTier($id, $meta, $tier) : Item{
        $block = new Item($id, $meta);
        $nbt = $block->getNamedTag() ?? new CompoundTag("", []);
        $nbt->tier = $nbt->setString("tier", $tier);
        $block->setCompoundTag($nbt);
        return $block;

 

Not work, the problem i think is NBT

 

Use CompoundTag::setString().
Also:
- Always prefer Item::get() over new Item().
- The ?? operator is not needed because Item::getNamedTag() must always return a CompoundTag.

PHP:

public function getItemTier($id, $meta, $tier) : Item{
    $block = Item::get($id, $meta);
    $nbt = $block->getNamedTag();
    $nbt->setString("tier", $tier);
    return $block;
}
