Hey, im a newbie at lua and i got a possible error because turtle didnt move

This is the code

function down()
  if turtle.detectDown() ~= false then
	turtle.down()
  end
end

down()

[remiX]

Your turtle needs fuel. Add coal to slot one and in a code add turtle.refuel()

Also, make sure to call the function. If you declare it, but never call it, the turtle would obviously never be told to move.

No... I have got fuel but turtle just ignore the program

Is that all the code in the program you're trying to run?

yes... should it be:

if turtle.detectDown() == false then
turtle.down()
end

?

Either that, or just make sure to call the function. Which you seem to (now) do in your edited first post.

I just forget to put on this topic the call of the function

[Lyqyd]

Oh, also, your original code would only have tried to move down if there were a block below it. Try this instead:

function down()
    if not turtle.detectDown() then
        turtle.down()
    end
end

down()

[civilwargeeky]

Yeah, like Lyqyd said, your program would make the turtle go down only if it DID detect a block.
You could use

 if not turtle.detectDown() then

like he said, or

 if turtle.detectDown() == false then 

or

 if turtle.detectDown() ~= true then 

or maybe even

--Pretty Risky here, I honestly don't know if this would work
if not turtle.detectDown() == true then

[PedroBarbosa]

It work! Thanks alot guys
