[Lua] Problem with orientation and position...

My head is burning with this code :D/>

Where is the error ? When I turn forward the turtle.. then it doing strange thinks :)/>

Thanks for the help !

rednet.open ("right")
PCID = 21

local positionx = 0
local positiony = 0

while true do
id, command = rednet.receive()
  if command == "go" then
    turtle.forward()

    turtle.back()

Well, your functions are all defined inside the command loop (so they get redefined every time the loop runs), but it looks like the only one that ever gets called is turtleforward. So you get a rednet command, execute it if it's in your list, and then you do a turtleforward(). What happens then depends on which direction the turtle can move.

What exactly are you trying to do?

Also, turtlerovno() seems entirely undefined. Should those calls be turtleforward()?

Oh, my bad. You're comparing turn to the function returns, so all those functions get called. And all of them return nil, which is what turn is, so all the stuff in them happens every time. That must be quite a dance your turtle performs after every command you give it.

No, wait, you change turn in the first thing. So only that sequence happens. Still a lot of nonsense happening there.

i tried to get into your code but i dont get why you do the things :D/>

here is a code that may gives you a clue what you should do. i will not guarantee that this code will work, but you should get a clue how it works.
i will check the code when im back home. and give update if not working :)/>

edit: note that im using Y as coordinate for the altitude level

Clueless: I dont now but your code doesnt work for me :/

I do this: It is ok ? :)/>

Take a look at my location API. It may give you a better sense of how this sort of thing should work.

i checked my code and its working
if you want the turtle to count up 1 from beginning when you tell him to go forward
just set Orientation to 3 in the script

To the OP, you still haven't explained what you want the turtle to do. If the program runs, then it runs (and hey, same thing if it doesn't run, really). That is to say, it does something, but without knowing what you want it to do we can't well find anything "wrong" with the program aside from things we simply assume you don't want it to do.

If it's now doing what you want, then congrats. If not, then please explain exactly what you want it to do and exactly what it does instead.
