Copyblock: The Ultimate Building Automation Mod for Minecraft
If you have ever spent hours placing the same block over and over while building a massive wall or floor, you already know the pain. Copyblock is a utility mod that solves this problem by letting you define an area and fill it with a template block instantly. Whether you are a survival player tired of tedious repetition or a map creator working on a huge project, this mod delivers serious time savings. It works with Forge and NeoForge on modern Minecraft versions, including 1.20.x and 1.21.x, so most players can jump right in.
What Does Copyblock Do?
Copyblock introduces two functional blocks and a history system that together handle repetitive construction tasks. The mod is designed for builders, redstone engineers, and map makers who want precise control over large regions without placing every block by hand.
Area Fill Mode
Place a Cloning Block to mark the first corner of your area. Put a template block above the base, then place a second Cloning Block at the opposite corner. The game instantly fills the entire selected region with that template block. This is perfect for laying floors, building walls, or duplicating patterns across a large zone.
Area Delete Block
The Delete Block works in the opposite direction. Use it to clear every block within a defined area and automatically remove the item drops that would normally clutter your world. This is a lifesaver when you need to excavate a large space or clean up an old build without leaving a mess behind.
History System with Undo and Redo
Mistakes happen, and Copyblock has your back. The mod supports Undo and Redo functions with a logic lock mechanism that prevents accidental triggers. By default, you have a 20-second window to undo an action, and you can adjust this timer to suit your workflow. The history system supports up to 20 steps, so you can roll back several operations if needed.
Controls and Commands
Getting started with Copyblock is straightforward once you know the hotkeys. The mod is disabled by default, so you need to activate it before the block logic will work.
- J – Enable or disable the mod logic (disabled by default)
- U – Undo the last action within the default 20-second window
- R – Redo a previously undone action
- K – Clear all mod base blocks from the world
- /copyblock undo_timer <sec> – Adjust how long undo remains available
One important note for multiplayer fans: on a server, the /copyblock command requires Operator permission. Without OP status, you cannot change the undo timer, so plan accordingly if you are playing on someone else's server.
Crafting Recipes
Both blocks use simple, early-game materials, which means you can craft them without grinding for rare resources.
- Copy Block: Three Cobblestone on the top row, Iron Ingot – Redstone Dust – Iron Ingot in the middle row, and three Cobblestone on the bottom row.
- Delete Block: Three Cobblestone on the top row, Stick – empty slot – Stick in the middle row, and three Cobblestone on the bottom row.
