In this tutorial, you will learn how to recreate a Lua program that controls a Minecraft turtle for automated strip mining. The program takes inputs for the mining area size and length, calculates fuel requirements, and performs the mining operation while managing the fuel level and item drops.
Prerequisites
- A basic understanding of programming concepts.
- Access to a Minecraft world with turtles enabled.
- Lua programming knowledge (basic syntax and functions).
- Knowledge of using a computer terminal within Minecraft.
Step-by-Step Instructions
1. Create a New Lua Program
Open your computer terminal within the Minecraft game and create a new Lua program. You can use the in-game edit command or an external text editor to write the program.
2. Define Parameters and Functions
Copy and paste the following code into your program:
-- Define the size and length of the mining area
local size, length = ...
-- Define the strip function
local function strip(len, ret)
for i = 1, len do
turtle.dig()
turtle.forward()
turtle.digUp()
end
if ret == true then
turtle.turnRight()
turtle.turnRight()
for i = 1, len do
turtle.forward()
end
end
end
-- Define the fuelCost function
local function fuelCost(sz, len)
local cost = sz * (((len * 2) + 4) + len * sz)
return cost
end
3. Check Fuel Level
Add the following code snippet to check the turtle’s fuel level and compare it to the calculated fuel cost:
-- Check fuel level
local fuel = turtle.getFuelLevel()
if fuel < fuelCost(size, length) then
error("Not Enough Fuel")
end
4. Set Up the Terminal Display
Include the following code to set up the terminal display with relevant information:
-- Clear the terminal and set cursor position
term.clear()
term.setCursorPos(1, 1)
print("Size: " .. size .. " | Length: " .. length)
print("Fuel Cost: " .. fuelCost(size, length) .. "/" .. turtle.getFuelLevel())
5. Start Mining
Add the code to initiate the mining operation:
-- Move the turtle forward to start mining
turtle.forward()
-- Begin mining loop
for i = 1, size do
turtle.turnLeft()
strip(length, true)
strip(length, true)
turtle.turnRight()
strip(4, false)
end
-- Move back to the starting position
turtle.turnLeft()
turtle.turnLeft()
strip((4 * size) + 1, false)
6. Drop Mined Items
Include the code to drop the mined items:
-- Drop mined items
for i = 1, 16 do
turtle.select(i)
turtle.drop()
end
7. Return to Starting Position
Finally, add the code to return the turtle to its starting position:
-- Return to the starting position
turtle.turnRight()
turtle.turnRight()
8. Save and Execute
Save your Lua program and execute it in the computer terminal within the Minecraft game. Provide the values for the size and length parameters as prompted.
The turtle should now automatically perform strip mining in the specified area, managing its fuel level and item drops efficiently.
