Railway Turtle: Lua related

I am writing a code for a turtle to mine through various things and lay tracks along the way. I am stuck as to what I should do to allow it to place more then the 64 minecarts it has in its inventory. I need a way to have it switch to using a different inventory location that has more tracks. I am thinking I could do some sort of if and then statement for it but I am unsure as to how I would execute this.


– Sets program up –
while true do
term.clear()
term.setCursorPos(12,1)
print("Made by Jordan Sinn")
term.setCursorPos(1,2)
print("Still in Alpha")
term.setCursorPos(1,3)
print("Multiple of 10")
term.setCursorPos(1,4)
print("Distance:")
input=read()

– Laying tracks –
for i = 1, input do
for i = 1,9 do
turtle.dig()
turtle.forward()
turtle.digDown()
turtle.select(1)
turtle.placeDown()
end

– Laying powered tracks –
turtle.dig()
turtle.forward()
turtle.digDown()
turtle.down()
turtle.digDown()
turtle.down()
turtle.digDown()
turtle.select(3)
turtle.placeDown()
turtle.up()
turtle.select(4)
turtle.placeDown()
turtle.up()
turtle.select(2)
turtle.placeDown()
end
end

Could you use the "Code" button, please ? It would be easier to look at you code if you did so.

local selected = 1

local function select()
 
  for i=1,16 do
	if turtle.getItemCount(i) > 0 then
	  turtle.select(i)
	  return true
	end
  end
  error("There is no track left")
end

--Call this if the program fails to place a track like so:
if not turtle.place() then
    select()
end

Is that something like what you're looking for?

*shivers* Do not overwrite select please :D/> (I know it's local but still…)

I've never encountered select before, although I see from testing that it is indeed a function. Honestly it doesn't look that useful anyway. I suppose I can see it for things like filtering out the first argument of os.pullEvent or some such thing, but I always put the results of os.pullEvent in a table anyway so it's a bit pointless.

Thanks everyone and sorry about not using the code button. How would I go about incorporating this into my code, just place it at the top or…

you have to include everything Bubba said at the top of the code
and then put this:

if not turtle.place() then
    select()
end

whenever you want to place tracks

This is my updated code. The program stops when it goes to lay the powered track and returns a nil. Im over my head at this point

local selected = 1
local function select()

  for i=1,16 do
	    if turtle.getItemCount(i) > 0 then
		  turtle.select(i)
		  return true
	    end
  end
  error("There is no track left")
end
--Call this if the program fails to place a track like so:
if not turtle.place() then
    select()
end
--Sets program up
while true do
term.clear()
term.setCursorPos(12,1)
print("Made by Jordan Sinn")
term.setCursorPos(1,2)
print("Still in Alpha")
term.setCursorPos(1,3)
print("Multiple of 10")
term.setCursorPos(1,4)
print("Distance:")
input=read()

-- Laying tracks --
  for i = 1, input do
  for i = 1,9 do
  turtle.dig()
  turtle.forward()
  turtle.digDown()
  turtle.select(1)
    if not turtle.place() then
	  select()
    end
  turtle.placeDown()
  end
-- Laying powered tracks --
  turtle.dig()
  turtle.forward()
  turtle.digDown()
  turtle.down()
  turtle.digDown()
  turtle.down()
  turtle.digDown()
  turtle.select(3)
  turtle.placeDown()
  turtle.up()
  turtle.select(4)
  turtle.placeDown()
  turtle.up()
  turtle.select(2)
  turtle.placedown()
  end
end

.-.
i fixed some things, im not sure it will work though

EDIT:
lolderp, i forgot i had placedown instead of placeDown
syntax highlighting ftw!
EDIT2:
forgot something else

also a note: put all the rails on the last 8 slots kthx

How did you do that Pixel? :P/>

the syntax highlighting or the fix?

syntax highlighting. I mean, I doubt you spent your day highlighting every word perfectly :P/>

Actually, please indent your code properly. it makes it much easier for us to help and for you to understand the code after some time. Don't know what i mean? example:
Unindented:

if foo then
for k, v in ipairs(bar) do
print(k..", "..v)
end
end

Indented:

if foo then
    for k, v in ipairs(bar) do
	    print(k..", "..v)
    end
end

thanks for the help pixle. I tried to run the program but the turtle loses the items as moves. It spits them out and moves away. I think another way of getting this to work is needed.

Actually i dont know what you have in slot 1 to 9 but i think the problem is that in the code of Pixel there is a lot of turtle.drop()
change them to turtle.placeDown() or turtle.place() where you have tracks or torches etc. and it should work.
