Maze solver using Turtle – Nullharp's Blog

Step 1: Open the ComputerCraft Computer
First, you’ll need to open the CC computer in the game. Right-click on the computer to access its gui.

Step 2: Create a New Program
In the computer’s interface, type edit maze_solver and press Enter. This command will create a new program file called maze_solver.

Step 3: Initialize Variables
Inside the program, start by initializing some variables:

				
					local complete = false
local facing = 0 -- 0: North, 1: East, 2: South, 3: West

These variables will help us keep track of the turtle’s orientation and whether the maze has been solved.

Step 4: Define Turn Functions
Define functions to turn the turtle right and left while updating its orientation:

				
					local function turnRight()
turtle.turnRight()
facing = (facing + 1) % 4
end

local function turnLeft()
turtle.turnLeft()
facing = (facing - 1) % 4
end

Step 5: Define Move Function
Create a function to move the turtle forward, handling obstacles and digging through blocks if necessary.

				
					local function moveForward()
    while not turtle.forward() do
        if turtle.detect() then
            turnRight()
        else
            turtle.dig()
        end
    end
end

Step 6: Main Maze-Solving Loop
Set up the main maze-solving loop:

				
					while not complete do
    moveForward()
    turnLeft()
    
    if turtle.detect() then
        turnRight()
    end
    
    while turtle.detect() do
        turnRight()
    end
    
    local success, data = turtle.inspectDown()
    if success and data.name == "minecraft:lime_concrete" then
        complete = true
    end
end

This loop will make the turtle navigate through the maze, turning left and right when necessary to explore the paths.

Step 7: Additional Actions
You can add any additional actions or logic you need after the maze is solved. For example, you can return the turtle to the starting point or print a success message.

Step 8: Save and Exit
To save your program, press Ctrl + Enter

Step 9: Run the Program
To run your maze-solving program, type maze_solver and press Enter in the computer’s interface.

That’s it! You’ve created a simple maze-solving program using CC:Tweaked in Minecraft. The turtle will navigate through the maze and stop when it finds a block named “minecraft:lime_concrete.”
