hello all ill make this question short it can get pretty long tho so bare with me here :P/>

im working on making a basic house building (10x10) program with while loops and if and elseifs so now my question is : on my program i have my functions and ifs and loops so far setup in this manner


function Fuel()
if turtle.getFuelLevel <= 1 then
  turtle.select(1)
  turtle.refuel(1)
 end
end
//other functions
i = 1
while i <= 10 do
if turtle.getItemCount(2) >= 20 then
  i = 1
  while i <= 10 do
	Fuel()
	Line()
	i = i + 1
  elseif turtle.getItemCount(2) <= 20
		  print("Need 20 in slot 2")
  end
end
end

and it seems after it finishes it stops and wont loop it over again please help me im a lua noob as you probably can tell mine is much bigger then this but i dont have access to the file to copy and paste if needed to i can finish the rest of it this is just the gist of it

let me format that for you:

Spoiler


function Fuel()
	if turtle.getFuelLevel <= 1 then
		turtle.select(1)
		turtle.refuel(1)
	end
end
//other functions
i = 1
while i <= 10 do
	if turtle.getItemCount(2) >= 20 then
		i = 1
		while i <= 10 do
			Fuel()
			Line()
			i = i + 1
		elseif turtle.getItemCount(2) <= 20
			print("Need 20 in slot 2")
		end
	end
end

alright. then theres a weird ending. so I'll fix that, too:

Spoiler



function Fuel()
	if turtle.getFuelLevel <= 1 then
		turtle.select(1)
		turtle.refuel(1)
	end
end
//other functions
i = 1
while i <= 10 do
	if turtle.getItemCount(2) >= 20 then
		i = 1
		while i <= 10 do
			Fuel()
			Line()
			i = i + 1
		end
	elseif turtle.getItemCount(2) <= 20
		print("Need 20 in slot 2")
	end
end

alright. now the problem you described. it appears because you are using a loop in a loop. no problem as far as they don't use the same index. in your case i. so so I'll fix that as well:

Spoiler



function Fuel()
	if turtle.getFuelLevel <= 1 then
		turtle.select(1)
		turtle.refuel(1)
	end
end
//other functions
i = 1
while i <= 10 do
	if turtle.getItemCount(2) >= 20 then
		k = 1
		while k <= 10 do
			Fuel()
			Line()
			k = k + 1
		end
		i = i + 1
	elseif turtle.getItemCount(2) <= 20
		print("Need 20 in slot 2")
	end
end

so. thats all i can do for now because i don't have enough information to test your program of functionality, so it's you turn. would be easier to help you if you posted the complete program. because i don't remember the function line(). correct me, but this function needs to be somewhere in your code, doesn't it?

ya my line function is just this


fucntion Line()
	turtle.select(2)  
	turtle.digDown()
	turtle.placeDown()
end

and i will try out every thing you have showed me there and see it its working

PS. Thank you so much i didnt even think about needing a different index XD shows how bad i am but im learning
