Description

Auto Replace

image

Select a region · mass-break · mass-fill — server-side, so blocks stay gone.

image

AutoReplace is a lightweight Fabric utility for Minecraft 26.2. Select a box like Litematica and break or fill the entire area in one action. Breaks and fills are executed on the server, so nothing reverts in singleplayer or multiplayer.

📋 Features

  • Area selection — right-click two corners (cyan outline, Litematica-style)
  • Mass break — break one block inside the selection → matching blocks in the box break server-side
  • Mass fill — pick a block from your hand or the world and fill the selection automatically
  • Simple Z menu — clean panel with toggles, tooltips, and a fill block preview
  • Server authority — no ghost blocks / no "blocks come back" failure
  • Paper plugin (optional) — same-network support for Paper/Spigot multiplayer servers
  • Safety caps — max 4096 blocks per action, range checks, unbreakable blocks ignored

🎮 How to Use

image

  1. Press Z to open the menu
  2. Enable Selection mode
  3. Right-click the first corner, then right-click the second corner
  4. Choose what you want:

🔨 Break

  • Turn Auto-break on
  • Mine one block inside the selection
  • The server breaks the rest (same block type if "Same block only" is on)

🧱 Fill

  • Hold a block → Use held block or Pick from world and right-click a block
  • With Fill on select enabled, the selection fills automatically
  • Or press ▶ Fill selection

⚙️ Menu Options

Option Description
Auto-break Mass-break when you mine a block inside the selection
