Smart Stack Refiller

Never run out mid-action again.

Smart Stack Refiller automatically refills your selected hotbar slot with matching items when a stack runs out. It’s lightweight, client-side, and designed to feel completely natural during gameplay.


✨ Features

  • 🔄 Automatically refills your hotbar when a stack is depleted
  • 📦 Only affects stackable items (blocks, food, etc.)
  • 🎯 Pulls matching items directly from your inventory
  • ⚡ Instant and seamless — no delay, no menus
  • 🧠 Smart behavior that avoids interfering with normal gameplay
  • 🛑 Prevents accidental refill when dropping items
  • 🚫 Disabled while inventory or other screens are open

⚙️ How It Works

When your held item reaches zero:

  1. The mod searches your inventory for a matching item
  2. If found, it swaps it into your hotbar
  3. You keep playing without interruption

No setup required. Just install and play.


🎮 Example Use Cases

  • 🧱 Building without constantly restocking your hotbar
  • ⛏️ Mining with uninterrupted block placement
  • 🍖 Eating food without manual switching
  • 🔥 Keeping torches or utility items ready at all times

🔌 Compatibility

  • ✔ Client-side only
  • ✔ Works in singleplayer and most multiplayer servers
  • ❌ Does not require installation on the server

⚠️ Some servers with strict mod rules may restrict automation mods.

⚠️ Limitations

💡 Design Philosophy

This mod is built to be:

  • Minimal
