Item Builder

Utility class for building ItemStacks with a fluent API. This is used to avoid having to duplicate code for creating ItemStacks across platforms. It provides methods for adding lore, setting custom data, hiding additional tooltip information, setting a custom name, and setting custom model data.

ItemBuilderExample.java

package com.example.item;

import net.minecraft.nbt.CompoundTag;
import net.minecraft.network.chat.Component;
import net.minecraft.world.item.component.CustomData;
import net.minecraft.world.item.ItemStack;

public class ItemBuilderExample {
  public static void main() {
    // Create a new ItemBuilder with a diamond sword
    ItemStack item = new ItemBuilder(Items.DIAMOND_SWORD);

    // Hide default additional tooltip information
    item.hideAdditional();

    // Set a custom name for the item
    item.setCustomName(Component.literal("Excalibur"));

    // Add lore to the item
    Component[] lore = new Component[] {
      Component.literal("A legendary sword"),
      Component.literal("with immense power")
    };
    item.addLore(lore);

    // Set custom model data for the item
    item.setModelData(123456);

    // Set custom data for the item
    CompoundTag customDataNBT = new CompoundTag();
    // Add custom data to the NBT tag then convert it to a CustomData object and set it to the item
    CustomData customData = new CustomData(customDataNBT);
    item.setCustomData(customData);

    // Modify the ItemStack directly if needed
    item.modifyStack(stack -> {
      // Perform modifications on the ItemStack here
      stack.setDamageValue(10); // Example: Set the damage value of the item
    });

    // Get the final ItemStack
    ItemStack finalItem = item.build();
  }
