Simple AutoTool Mod

A client-side Minecraft Fabric mod for version 1.21.4 that automatically switches to the best tool in your inventory when mining blocks.

Features

• Automatic Tool Switching: Detects the block you're targeting and automatically selects the most effective tool from your hotbar
• Smart Detection: Recognizes different block types and matches them with appropriate tools:
  • Pickaxe for stone, ores, and other hard blocks
  • Axe for wood and wooden materials
  • Shovel for dirt, sand, gravel, and similar blocks
  • Hoe for farmland and plant-based blocks
• Manual Override: Hold Shift (sneak) to disable auto-switching and maintain manual control
• Toggle Functionality: Press R (configurable) to enable/disable the mod with on-screen feedback
• Client-Side Only: Works on any server without requiring server-side installation
• Hotbar Only: Only switches between tools in your hotbar (slots 0-8)

Installation

Download and Install:

• Download the latest release from the releases page
• Place the .jar file in your mods folder
• Launch Minecraft with the Fabric profile

Usage

1. Install the mod and launch Minecraft
2. Join any world (singleplayer or multiplayer)
3. Look at a block you want to mine
4. The mod will automatically switch to the best tool in your hotbar
5. Hold Shift to temporarily disable auto-switching
6. Press G to toggle the mod on/off (you'll see a chat message confirming the status)

Configuration

• Toggle Key: The default key to toggle the mod is G. You can change this in Minecraft's Controls settings under the "AutoTool" category.

How It Works

1. Block Detection: The mod continuously monitors what block you're looking at
2. Tool Analysis: It checks all items in your hotbar and calculates their mining efficiency for the target block
3. Smart Switching: It switches to the tool with the highest mining speed multiplier
4. Respect Player Intent: It won't switch when you're sneaking, allowing for manual control
