Can someone help me with this turtleprogram?

Im relatively new to CC and I try to get some programs, this is more or less my first.


The purpose of the program is to place a variable amout of blocks in the shape of a rectangle.
I know that the autorefill is not in there, but my problem right now is, that it turns itself around on the same block or that it builds an interesting construct, but either way it doesnt work right.

local arg1,arg2,arg3,arg4 = ...
  write "length="
  print (arg1)
  write "width="
  print (arg2)
  write "height="
  print (arg3)

fwdvar = tonumber(arg1)
sdevar = tonumber(arg2)
hgtvar = tonumber(arg3)
hgt = 0
while hgt < hgtvar do
fwd = 1
while fwd < fwdvar do
  turtle.select(5)
  turtle.placeDown()
  turtle.forward()
  fwd = fwd + 1
end
turtle.turnRight()
sde = 1
while sde < sdevar do
  turtle.placeDown()
  turtle.forward()
  sde = sde + 1
end
turtle.turnRight()
fwd = 1
while fwd < fwdvar do
  turtle.placeDown()
  turtle.forward()
  fwd = fwd + 1
end
turtle.turnRight()
sde = 1
while sde < sdevar do
  turtle.placeDown()
  turtle.forward()
  sde = sde + 1
end
turtle.up()
turtle.turnRight()
hgtvar = hgtvar +1
end

(sorry,if there is a spoiler thing, I cant find it)

What do you mean by "doesn't work right"?
Describe what it does that you think isn't correct.

You may want to look into for loops. They make this sort of thing much easier.

Aside from that, a picture of what it does do vs what you want it to do would be helpful.

it rotates at this block the whole time, the other thing I cant recreate


@KingofGamesYami Where exactly would you place a loop?

Does your turtle have fuel?

I pla with FTB Ulti, dont know the CC version, but i dont need fuels there afaik

Try typing this into your turtle:

> lua
> turtle.forward()

Does the turtle go forward?

nop. it returns false

Then you need fuel

Put something you can burn in the turtles inventorty like coal and then type refuel or in a program or Command Prompt call turtle.refuel(Amount)

But why did it work withotu fuel then?

Try typing this instead. Because I'm not so sure you do need fuel. Since the lua prompt didn't say that you needed fuel and only said false.

lua
turtle.getFuelLevel()

Say what that tells you

it tells me 0, before i needed no fuel though

Server probably changed the config then. Since it does say 0, then you do need fuel. Get something that you can put in a furnace for fuel and put it in the turtle, and then type refuel.

well, now it just places the first row of blocks :/

And then what does it do? Run out of blocks to place?

no, it runs arond crazy, but could fix it, it works now, thanks for the help!
