(Check the gallery for a video demonstration [v2.0.3])

Last release   

V3.0.5

-Fixed and adjusted rotation of drill heads
-Fixed commands using item ID's on fabric 26.1
-Fixed all "missing texture" warnings (for particles) appearing in the log when lauching minecraft (maybe one or two survived concerning "air blocks" but it's minor)
-Added solidification of sand and gravel into sandstone and stone + a cleaning on the drill layer to definitively block all fluids infiltration into the drilled tunnel 
-Drills now emit light (like a vanilla light block)

What this mod does

• Adds drilling machines
• Automatically mines large straight tunnels
• Controlled mining in all directions

How to use?

• Place a drill
• Fill the tank with right click + redstone in hand
• ON/OFF with right click without nothing in hand
• Repair with right click + diamants in hand
• Retrieve your drill with Shift + right click without nothing in hand (or "mine" it)
• Limited of 1 drill active per player configurable with command (1-64)
• A drill placed with fuel in the tank is active and follow UUID of the last player who filled the tank

Drills

• Drill prototype: mines 3x3 with normal drops (t1)
• Advanced excavator: mines 5x5 and only whitelisted blocks drop (t2)
• Mountain piercer: mines 7x7 with the same whitelist logic and higher durability (t3)
• Can be upgrade with somes Enchanted Books (Unbreaking, Fortune, Silk touch, Mending)
• All the drills get now fire immunity

Drill behavior

• Moves forward in the direction it is facing
• One step equals one block forward and one full layer mined
• One step every 2 seconds
• Various visual and sound effects 

Fuel and durability

• Powered by redstones, use them directly on the block to fill the tank
• Fuel is consumed with each step directly from an integrated tank 
• A fuel gauje has been added and visible on the textures 
• Durability is consumed every step
• Repairable with diamants, use them directly on the block (33%, 20% and 12.5% respectively, depending on drill efficiency)

Block and terrain handling

• Unbreakable blocks stop the drill
• Whitelisted blocks drop normally
• Other blocks will be deleted
• Fluids are solidified before mining 
• Drill stop and drop when open air is detected ahead (3 "air" blocks in a raw)

Configuration

• Recipes can be modified in a .jar data/mountainpiercer/recipes
• You need to use correct item IDs if you do any change! (ex: minecraft:diamond)
• The .jar can be opened by any decompression software (7zip, WinRAR, etc.)

Command prompt (use /reload to validate any change):

/drill recipes on|off

/drill recipes status

/drill keep add|remove     ………………………………….… (whitelist, add|remove parent blocks; ex: to keep emerald, add emerald_ore_block; also you can edit the config file manually)   

/drill unbreakable add|remove     ……………………….. (same logic)

/drill config status

/drill config set max_active <1-64>   ………………… (1 by default)

/drill config set fuel_per_redstone <1-1024>    … (5)

/drill config set fuel_capacity t1     ……………………. (15)

/drill config set fuel_capacity t2     ……………………. (30)

/drill config set fuel_capacity t3     ……………………. (45)

⚠️Some functions may vary slightly depending on the version.

⚠️Although the drills are designed to withstand micro-lags, reactions in the event of prolonged lags are unknows.
