Split String

Hey,

i found this mod yesterday and im very impressed of it.
Now i am trying to make my own scripts.

The problem is: I want to split a string into chars.

Like: var = 13121012
To: var[1] = 1 var[2] = 3 … var[8] = 2

I am used to Java. ( i started learning lua after i found this mod )
- var.toCharArray();

Now i need the same function for lua, but i cant find it :/

Does anybody know it?

Thanks a lot, bepZ

I'm assuming you mean this:

var = "13121012"

You can use the following to obtain characters of it:

string.sub(var, 1, 1) -- Will return "1"

var:sub(2, 2) -- Will return "3"

var:sub(3, 4) -- Will return "12"

Note that in order to use var:sub, the type() of var is required to be string.
You can use string.sub(number, …), as this will internally convert the number to a string.

Thats what i was looking for, thanks!

I got a new problem, now it says "Infinity", maybe because my string is very long.

Here is my string: 001101100011111110111111111111111111011111111111111110011111111111111111111111111011111110001101100

I want to read one char at a time.

Is there any way to solve my problem?

Your 'string' is probably a number, try this:

local s = tostring(your string that is probably a number)
print(s:sub(1, 3)) -- or some other parameters to sub

Edit: Just did some testing; any numbers that are long will yield "inf" or "Infinity" when turned into a string; to solve this, make sure your variable is a string to start with, and not a number.

I am so dumb, i made a mistake.. i forgot the "" around my number..

Shame on me!

I dont understand why the turtle is not placing the blocks. Here the script.

buildnumber = "001101100011111110111111111111111111011111111111111110011111111111111111111111111011111110001101100"
count = 1
for x = 0, 5, 1 do
for y = 0, 10, 1 do
  for z = 0, 7, 1 do
   write(string.sub(buildnumber, number, number))
   -- block placement
	kind = string.sub(buildnumber, number, number)
	if kind == 1 then
	 turtle.placeDown(1)
	elseif kind == 2 then
	 turtle.placeDown(2)
	elseif kind == 3 then
	 turtle.placeDown(3)
	end
   -- block placement end
   turtle.forward()
   number = number + 1
  end
  for z = 0, 7, 1 do
   turtle.back()
  end
  turtle.turnRight()
  turtle.forward()
  turtle.turnLeft()
end
turtle.turnLeft()
for y = 0, 10, 1 do
  turtle.forward()
end
turtle.turnRight()
turtle.up()
end
for x = 0, 5, 1 do
turtle.down()
end

The turtle moves where i want it to move, but it doesnt place the block.

You need to put quotes around your 1, 1 ~= "1"

oh.. im blind.

thanks.

This will return a table containing all the chars.

function toCharTable(string)
	 local string = tostring(string)
	 local chars = {}
	 for n=1,#string do
		 chars[n] = string:sub(n,n)
	 end
	 return chars
end

vars = toCharTable(4523789)
--Will return:
--vars[1] = 4
--vars[2] = 5
--vars[3] = 2
--And So on.
