A simple quality-of-life Minecraft mod that lets you press a hotkey while hovering over any item to instantly duplicate it—non-stackable items are cloned with full NBT data, while stackable items have their quantity doubled.

Description

Mod Overview

This mod introduces a legendary tool—the Pointer Duplicator. It can duplicate items in your inventory and containers, and it can also duplicate the block you're looking at directly into your inventory. It's the ultimate "duplication master" for Survival Mode.


Items

Pointer Duplicator

  • Rarity: Epic (purple name)

  • Stack size: Up to 64

  • Durability: None (never wears out; never disappears from use)

Two Core Functions:

  1. Duplicate Hovered Items: Open any container interface (inventory, chest, crafting table, etc.), hold the Pointer Duplicator, hover your mouse over an item slot, and press R to duplicate that item.

  2. Duplicate Blocks: Simply hold the Pointer Duplicator and right-click on any block in front of you to receive a duplicate of that block as an item.

  • Location: Creative inventory → Tools & Utilities tab


Crafting Recipe

Open a 3×3 crafting table and place materials in the following positions:

 
 
Position Material
Top row, center (slot 2) Iron Ingot
Middle row, left (slot 4) Amethyst Shard
Middle row, center (slot 5) Ender Pearl
Middle row, right (slot 6) Redstone Dust
Bottom row, center (slot 8) Stick

Leave all other slots empty. You will receive 1 Pointer Duplicator.


How to Use

Duplicating Hovered Items

  1. Hold the Pointer Duplicator (main hand or offhand both work).

  2. Open your inventory, a chest, or any interface with item slots.

  3. Hover your mouse over the item you want to duplicate.

  4. Press R (rebindable in settings).

Duplicating Blocks

  1. Hold the Pointer Duplicator.

  2. Aim at the target block.

  3. Right-click on the block.


Effect Details

 
 
Item Type Effect
Non-stackable items (tools, weapons, armor) Perfect 1:1 clone. Enchantments, durability, and custom names are all preserved.
Stackable items (dirt, iron ingot, etc.) Quantity is doubled by default, capped by the item's max stack size.
  • Duplicated items automatically enter your inventory. If your inventory is full, they will first try to stack onto nearby identical items; if there's still no space, they will drop on the ground—never vanishing into thin air.

  • After each successful duplication, the Pointer Duplicator enters a brief cooldown (approximately 0.25 seconds) to prevent accidental spam.


Important Notes

  • Shift = Safety Lock: Holding Shift will prevent duplication from triggering, helping you avoid accidental copies while organizing items.

  • What cannot be duplicated: Blocks with no corresponding item form (such as air, flowing water/lava, etc.) cannot be duplicated. The Pointer Duplicator itself also cannot be duplicated.

  • Block duplication is "basic": It only duplicates the block's default form. It will not read or copy the contents stored inside containers like chests or furnaces.

  • No XP cost: Duplication is free by default. All settings (toggle on/off, multiplier, cooldown, XP cost, etc.) can be adjusted in the mod configuration file config/pointer_duplicator.toml.

Mod 简介
这个模组加入了一件神器——指针复制器。它能帮你复制背包、箱子里的物品,还能复制你面前方块的物品,是生存模式的"复制大师"。

物品列表
指针复制器(Pointer Duplicator)
一件史诗(紫色)品质工具,可堆叠 64 个,不消耗耐久、不会在使用中消失。
两大功能:
复制悬停物品:打开任意容器界面(背包、箱子、工作台等),手持指针复制器,鼠标悬停在某个物品槽位上,按下 R 键,即可复制该物品。
复制方块:直接手持指针复制器,右键点击面前的任意方块,就能得到该方块物品的复制。
它出现在创造模式物品栏的**"工具与杂项"**选项卡里。
合成配方
打开 3×3 合成台,按下面的位置摆放材料:

位置    材料
第一行中间(第 2 格)    铁锭
第二行左边(第 4 格)    紫水晶碎片
第二行中间(第 5 格)    末影珍珠
第二行右边(第 6 格)    红石粉
第三行中间(第 8 格)    木棍
其余格子留空。完成后得到 1 个指针复制器。

玩法说明
复制悬停物品
将指针复制器拿在手上(主手或副手均可)。
打开你的背包、箱子或任何有槽位的界面。
把鼠标悬停在想要复制的物品上。
按下 R 键(可在设置中改键)。
复制方块
手持指针复制器,对准目标方块。
右键点击该方块。
效果细节
单件/不可堆叠物品(如工具、武器、盔甲):完整复制 1 件,连附魔、耐久、名字都原样保留。
可堆叠物品(如泥土、铁锭):默认让数量翻倍,并受该物品最大堆叠数量限制。
复制出的东西会自动进入你的背包;如果背包满了,会优先堆叠到附近同类物品上,实在放不下就会掉落到地上,不会凭空消失。
每次复制成功后,指针复制器会进入短暂冷却(约 0.25 秒),避免连点误操作。
注意事项
Shift 安全锁:按住 Shift 时不会触发复制,防止你在整理物品时手滑误复制。
无法复制的东西:没有对应物品的方块(如空气、流动的水/岩浆等)不能复制;指针复制器本身也不能被复制。
方块复制是"基础版":它只复制方块的普通形态,不会读取箱子、熔炉这类容器内部存的东西。
复制不消耗经验,默认是免费的。所有设置(开关、倍率、冷却、经验消耗等)都可以在模组配置文件 config/pointer_duplicator.toml 中调整。
