NullCycle Auto-Restock

The Ultimate Building & Mining Quality-of-Life Mod for Fabric

Never get interrupted while building a massive wall, and never swing bare fists when your diamond pickaxe breaks mid-grind.

NullCycle Auto-Restock monitors your hand slots in real time. The moment a block stack runs out or a tool breaks, the mod instantly scans your inventory in milliseconds and pulls a matching item or tool directly into your active hand.

No screen openings. No flow interruptions. Pure uninterrupted gameplay.

The Problem & The Solution

• Running out of building blocks: You are bridging or building a wall, your stack hits zero, and you place air or fall off your scaffolding. Solution: The next stack of the exact same block is swapped into your active hotbar slot in under a tick (50 ms).
• Breaking tools while strip mining: Your pickaxe breaks while mining deepslate, and you punch solid rock with your bare hand. Solution: An identical tool - or the next best tool tier with healthy durability - is equipped instantly.
• Heavy inventory mods: Bloated inventory managers with complicated GUIs often reorder your entire inventory against your will. Solution: NullCycle does one job with zero bloat. It only touches the slot that just became empty, leaving your custom hotbar layout intact.

Core Features

1. Instant Block Restocking

• Works with all building blocks (Stone, Deepslate, Wood, Glass, Terracotta, Concrete, etc.).
• Prioritizes full stacks from inventory slots 9-35 so you can build longer without reloading.

2. Intelligent Tool Replacement & Tier Fallback

• Supports Pickaxes, Axes, Shovels, Hoes, Swords, Shears, Bows, Crossbows, and Fishing Rods.
• Exact Match First: If you have another duplicate tool, it gets equipped immediately.
• Smart Tier Fallback: If you run out of Diamond Pickaxes, NullCycle safely equips the next best available pickaxe (Netherite > Diamond > Iron > Stone > Wood).
• Durability Guard: Tools with 3 or fewer durability points remaining are automatically skipped to prevent accidentally breaking precious gear.

3. Offhand Support

• Keep placing torches while mining without manually reloading your offhand slot.
• Also supports offhand building blocks, food, fireworks (for Elytra flight), and consumables.

4. Smart Anti-Glitch & Intentional Action Safeguards

• Drop Protection: Intentionally dropping an item with the 'Q' key will never trigger an auto-restock.
• Container Safety: When you open a Chest, Furnace, Anvil, Crafting Table, or your own Inventory GUI, restock is paused so your manual sorting is never disturbed.
• Hotbar Immunity: Other hotbar slots (such as your sword in slot 1 or food in slot 2) are preserved. The mod only pulls replacements from main backpack slots 9-35.

5. Non-Intrusive Audio & HUD Feedback

• Subtle audio feedback confirming successful restocks.
• Clean Action-Bar message above your hotbar displaying remaining inventory stacks (e.g., Auto-Restock: Cobblestone - 4x remaining) without cluttering the chat log.

6. Quick In-Game Toggle

• Press 'V' (customizable under Options -> Controls -> Key Binds) to enable or disable the mod instantly at any time.
