adding info to items

[theoneandonly2004]

OK so to explain quickly what I want to do,I want to add information to items when they are crafted to say who the items owner is (for multiplayer to help prevent item stealing etc). I know how to add info to my own items but would also like it added to vanilla ones as well

So I have a crafting handler set up and am trying to add the info but i'm not sure if i'm adding it right to be called (mustn't be if it isn't working). I do however know that the handler works for its other purposes so it is set up right just not the adding info part.

 

so anyone know what i'm doing wrong with it? I'm sure it's something simple. But thanks for any help

 

public class CraftingHandler
{
   @SubscribeEvent
   public void onPlayerItemCrafted(PlayerEvent.ItemCraftedEvent event)
   {
      List<String> info=new ArrayList<String>();
      info.add(event.crafting.getItem().getUnlocalizedName()+ ": owned by " + event.player.getCommandSenderName());
      System.out.println(info.get(0));
      event.crafting.getItem().addInformation(new ItemStack(event.crafting.getItem()),event.player,info,false);
  }
}

Use the NBTTagCompound in the ItemStack (ItemStack#stackTagCompound).

 

To add to this:

To show info to vanilla items, you need to

- create an NBTTagList and storing each line of your info into that list

- create a new NBTTagCompound and save that list with the key

Lore

- get the item's NBTTagCompound (or create a new one) and store the new NBTTagCompound, which contains that list, into that with the key

display

. If you've created a new one, store the NBT in the item.

 

A note: it defaults to format this in dark purple and italic. If you don't want that, reset the formatting by prepending

EnumChatFormatting.RESET

to each of your info lines.

I am looking a tooltip so when the mouse rolls over it then it would display the owner under the name.

 

But am looking into the NBT compounds now so thanks for the help guys

For the tooltip itself you'll have to override addInformation

I know how to add info to my own items but would also like it added to vanilla ones as well

So you see, overriding addInformation is not applicable in this case

If you want to change the tooltip of a vanilla item, you can use the

ItemTooltipEvent

.
