Buggy Mining/Printing code.

Title: Buggy Mining/Printing code.

So, I’m completely new to code and have been working on a code to mine the ‘length and width’ chosen; however, it seems to be full of bugs. I’ve come to the point where I’m just scratching my head wondering why it’s not working. If I could get some help on this and any pointers you feel like sharing that would be great.

The bugs that I know about are:
o Printing amount of blocks stays at “Mined 1 block” when I was trying to get it to count and print the total blocks mined to that point.
o When mining a straight line turtle continues forever. (I believe this is because finish and length aren’t being compared correctly)
o When mining a length of 3 and width of 3 the turtle goes in a square like this:
>>>>
^__ v ← Start, forward being down.
<<<<
It's supposed to look like this:
__v ← Start, forward being down.
v<<
>>v
v<< ← And then come back to the starting position.

Anyway, here’s the code:

--Declare locals.
local tArgs = {...}
local length = tArgs[1]
local width = tArgs[2]
   width = width - 1
local face = 1
local blocks = 0
local finish = 0


--Create functions.
function left(face)
   if turtle then turtle.turnLeft() end
	  face = face - 1
   if face < 1 then face = face + 4 end
   return face
end

function right(face)
   if turtle then turtle.turnRight() end
   face = face + 1
   if face > 4 then face = face - 4 end
   return face
end

function addB(blocks)
   blocks = blocks + 1
   if blocks > 1 then
	  print (‘Mined ‘..blocks..’ blocks.’)
   end
   if blocks == 1 then
	  print (‘Mined ‘..blocks..’ block.’)
   end
   return blocks
end

function digWidth(width)
   For a = 1, width do
	  while turtle.detect() == true do
		  turtle.dig()
		  addB(blocks)
		  sleep(0.5)
	  end
	  turtle.forward()
	  while turtle.detectUp() == true do
		  turtle.digUp()
		  addB(blocks)
		  sleep(0.5)
	  end
	  while turtle.detectDown() == true do
		  turtle.digDown()
		  addB(blocks)
		  sleep(0.5)
	  end
   end
end

function walkWidth(width)
   For dNCT = 1, width do
	  turtle.forward()
   end
end

--Execute code.
while finish ~= length do
   if face == 1 then
	  while turtle.detect() == true do
		 turtle.dig()
		 addB(blocks)
		 sleep(0.5)
	  end
	  turtle.forward()
	  while turtle.detectUp() == true do
		 turtle.digUp()
		 addB(blocks)
		 sleep(0.5)
	  end
	  while turtle.detectDown() == true do
		 turtle.digDown()
		 addB(blocks)
		 sleep(0.5)
	  end
	  finish = finish + 1
	  if width > 0 then
		 right(face)
		 digWidth(width)
		 if finish == length then
			left(face)
			left(face)
			walkWidth(width)
			right(face)
		 end
	  end
   end
   if finish ~= length then
	  if face == 2 then
		 left(face)
		 while turtle.detect() == true do
			turtle.dig()
			addB(blocks)
			sleep(0.5)
		 end
		 turtle.forward()
		 while turtle.detectUp() == true do
			turtle.digUp()
			addB(blocks)
			sleep(0.5)
		 end
		 while turtle.detectDown() == true do
			turtle.digDown()
			addB(blocks)
			sleep(0.5)
		 end
		 finish = finish + 1
		 left(face)
		 digWidth(width)
		 if finish == length then
			right(face)
		 end
	  end
   end
   if finish ~= length then
	  if face == 4 then
		 right(face)
		 while turtle.detect() == true do
			turtle.dig()
			addB(blocks)
			sleep(0.5)
		 end
		 turtle.forward()
		 while turtle.detectUp() == true do
			turtle.digUp()
			addB(blocks)
			sleep(0.5)
		 end
		 while turtle.detectDown() == true do
			turtle.digDown()
			addB(blocks)
			sleep(0.5)
		 end
		 finish = finish + 1
		 right(face)
		 digWidth()
		 if finish == length then
			left(face)
			left(face)
			walkWidth(width)
			right(face)
		 end
	  end
   end
end

Again, any help or guidance would be much appreciated.

Hello!
I don't know really, what you want, but try this:

count=0
write("Width: ")
width=io.read()
write("Altitude: ")
alt=io.read()
mineFlat(width, alt)
function mineFlat(width, alt)
  print(width*alt.." blocks mined")
  for asd=1,alt do
  turtle.refuel(1)
  turtle.digDown()
  turtle.down()
	for asdx=1,width-1 do
	  turtle.dig()
	  turtle.forward()
	  count=count+1
	end
  turtle.turnLeft()
  turtle.turnLeft()
  end
end

Place a turtle on the ground


Put fuel into the first slot. Hope it will work :)/>

Try this… look at some errors

Thanks for the codes guys, I'll mess around with them to understand some things that work :)/> If anyone else has more ideas on this code I would love to learn more.
