This allows you to add items to the game!

Create the Item Representation

Before you can add the item, you need to create an Item Representation which will allow you to set the properties of the item you want to add.
This is where the VanillaFactory comes in:

mods.contenttweaker.VanillaFactory.createItem(String unlocalizedName);

Import the representation Package

It might be required for you to import the package if you encounter any issues, so better be safe than sorry and add the import.
import mods.contenttweaker.Item;


To get/set the properties you can either use the respecting ZenGetters/Setters or the ZenMethods:

//property name: maxStackSize
item.maxStackSize = 16;
Property Name Type Required Default Value Description/Notes

Registering the item

You need to call this method to register the item in the game!
Otherwise nothing will happen!
After you have called this function, you cannot un-register the item or change any of it’s properties!


Example Script

#loader contenttweaker
import mods.contenttweaker.VanillaFactory;
import mods.contenttweaker.Item;
import mods.contenttweaker.IItemRightClick;
import mods.contenttweaker.Commands;

var zsItem = VanillaFactory.createItem("zs_item");
zsItem.maxStackSize = 8;
zsItem.rarity = "rare";
zsItem.creativeTab = zsCreativeTab;
zsItem.smeltingExperience = 10;
zsItem.toolClass = "pickaxe";
zsItem.toolLevel = 5;
zsItem.beaconPayment = true;
zsItem.itemRightClick = function(stack, world, player, hand) {"scoreboard players set @p name 5", player, world);
    return "Pass";

Localising the item

You will need to add Name to the responding language files.
Example in en_us.lang file itemName Here will show Your itemName Here in the game.

Alternatively, you could use CraftTweaker’s localization feature, though it’s recommended using the language files!
