ChunkMiner

--Written by Jacob Christensen, 11/26/2022
--Program Description: This program will mine out a 16x16 chunk starting from (0,16).

--Program Start--
print("Mmm I'm so hungry, let my feast begin!")

--Function Definition--

--LeftProcess - Turn Left: When the turtle is at the end of a line and needs to turn left. Turtle will turn left, mine, move forward, turn left again.
function LeftProcess()
    turtle.turnLeft()
    turtle.dig()
    turtle.forward()
    turtle.turnLeft()
end

--RightProcess - Turn Right: When the turtle is at the end of a line and needs to turn right. Turtle will turn right, mine, move forward, turn right again.
function RightProcess()
    turtle.turnRight()
    turtle.dig()
    turtle.forward()
    turtle.turnRight()
end

--MineLineProcess - Mine 15 blocks: This is where the turtle will mine out the line in front of it. Looping through mine, move forward 15 times.
function MineLineProcess()
    for i=15,1,-1 do
        turtle.dig()
        turtle.forward()
    end
end

--EndOfLayerProcess - 180 and mine: This is where the turtle is at the end of the layer, it will turn around, mine down one block and be ready for next layer start.
function EndOfLayerProcess()
    turtle.turnRight()
    turtle.turnRight()
    turtle.digDown()
    turtle.down()
end

--StartingProcess - Mine/Move Down turn left: This is where the turtle starts. It will mine one block down and move there it will then turn left and be ready to begin.
function StartingProcess()
    turtle.digDown()
    turtle.down()
    turtle.turnLeft()
end

--LayerOneProcess: This process will have the turtle make it's first turn right & last turn right.
function LayerOneProcess()
    MineLineProcess()
    for i=7,1,-1 do
        RightProcess()
        MineLineProcess()
        LeftProcess()
        MineLineProcess()
    end
    RightProcess()
    MineLineProcess()
    EndOfLayerProcess()
end

--LayerTwoProcess: This process will have the turtle make it's first turn left & last turn left.
function LayerTwoProcess()
    MineLineProcess()
    for i=7,1,-1 do
        LeftProcess()
        MineLineProcess()
        RightProcess()
        MineLineProcess()
    end
    LeftProcess()
    MineLineProcess()
    EndOfLayerProcess()
end

--Starting Sequence--

StartingProcess()

--Turtle will go down 128 blocks with current i value, feel free to change. (Future program upgrade, prompt turtle to ask for i value.)
for i=64,1,-1 do
    LayerOneProcess()
    LayerTwoProcess()
end
