🔹 Features
⛏️ Mining Modes
3x3 Mining – Breaks blocks in a 3x3 area around the targeted block.

10x10 Mining – Breaks blocks in a 10x10 area around the targeted block.
Tunnel Mining – Mines blocks in a straight line into the wall from the selected face.
Stairs Mining – Mines blocks diagonally to create a staircase while following the player's direction.
Adaptive Mining – Automatically searches for connected blocks of the same type using an adaptive vein-mining system.
🔗 Adaptive Mining
The Adaptive mode uses a connected-block search system to find blocks of the same type as the targeted block.
Supports mining connected ores, logs and other identical blocks.
Maximum limit of 128 blocks.
Press C to switch between:
64 blocks
128 blocks
This allows you to quickly choose between a smaller or larger mining limit depending on the situation.
🎮 Controls

Keybind to switch between mining modes.
C – Switch the Adaptive mining limit between 64 and 128 blocks.
Mining state, selected mode and other information are displayed through the HUD.
🛡️ Tool Durability & Safety
LTB Ultimine includes server-side durability protection to prevent the tool from being completely consumed during an Ultimine operation.
Tool durability is checked for every block mined.
Mining stops when the tool reaches the safety limit.
Client-side durability monitoring warns the player when the tool has 10 durability or less.
Normal Minecraft drops are preserved.
Supports normal tool behavior, including Fortune and Silk Touch.
🖥️ HUD & Block Highlight
The mod provides a client-side HUD showing:
Current LTB Ultimine status.
Selected mining mode.
Low tool durability warning.
Before mining, affected blocks can also be highlighted with a white outline, allowing the player to see which blocks will be mined.
🌐 Server & Network
LTB Ultimine uses client-server synchronization to keep the player's mining state synchronized.
The server tracks:
Whether LTB Ultimine is enabled.
The selected mining mode.
The current maximum block limit.
Mining operations are validated and executed on the server to provide consistent behavior in multiplayer.
