Item naming

How would I go about not changing an items custom name, but adding a new line to it with \n. Keep in mind, i dont want to change the original line, just add to it.

 

I think you could use something like this:

PHP:

 /*** @var Item $item ***/
 $item->setCustomName($item->getName()\n . /*"Your Text Here"*/); 

 

PHP:

$item->setCustomName($item->getName()."\n"."New Name");

 

it tells me to define $item do i do $item = Item::get(279, 0, 1);

 

That should work.

 

Yes
$item should be an instance of the Item class

PHP:

$item = Item::get(279,0,1);
$item->setCustomName($item->getName()."\n"."New Name");

 

Ok I added the code but I want it to be the item the player is holding not a diamond sword

 

This is the development section, you should know how to do it on your own before asking others to just give you code.

 

PHP:

 /*** @var Player $player ***/
$item = $player->getInventory()->getItemInHand();
