AutoSwap

A client-side mod that automates inventory management and equipment swapping during gameplay. It detects durability loss, empty item stacks, and block-breaking actions to equip the correct items from your inventory automatically.

Client-side only (no server installation required). Fully compatible with singleplayer.

Features:

• Smart Tool Selection: Switches to the most efficient tool the moment you start mining a block, and won't replace a tool that's already the right type.
• Auto Weapon on Attack: Optionally draws your best sword from your inventory the instant you start hitting a mob — the combat counterpart of tool selection. Leave it off and AutoSwap simply never swaps off your weapon while a mob is in your crosshair.
• Gear Replacement: Automatically equips a matching tool, weapon, or armor piece from your inventory when the currently equipped one breaks.
• Offhand Replenishment: Keeps your off-hand stocked — when the held item is used up, AutoSwap refills it from a list you control. Add a Totem of Undying, shield, or any item through the built-in creative-style item picker (or by item id).
• Stack Refills: Automatically refills the active hotbar slot with identical blocks or torches when the current stack is depleted.
• Double-Jump Elytra: Equips an elytra from your inventory instantly upon performing a double jump, and swaps your chestplate back when you land.
• Restore After Auto-Tool: Puts the item you were holding back in your hand once you stop mining.

All features are completely modular. Each function can be enabled or disabled individually through the redesigned in-game settings screen, the configuration file, or via dedicated keybinds bindable under Controls → AutoSwap.

Translated into 10 languages — English and Russian are complete; other locales are in progress.
