Attempt to Call Nil Error

Keep getting an "Attempt to Call Nil" error in line 6. Nothing I seem to do fixes it, though..

g = 0

print("Welcome to MineHall 2.0")

print("How long would you like the tunnel:")

len = tonumber(read())

turtle.select(1)

turtle.refuel()

while g < len do

turtle.dig()

turtle.forward()

turtle.digUp()

turtle.digDown()

g = g+1

end

print("Finished mining.")

Any and all help is appreciated. :)/>

You need to select the quantity to refuel in turtle.refuel(), like: turtle.refuel(1) will refuel with 1 unit from selected slot

But if left blank, it refuels with the entire stack, no?

EDIT: Tried with (1) in the spot, still a nil value.

Yes.

What version of CC are you using, and have you maybe changed the settings for turtles to NOT use fuel.

I am using 1.3, as it is on a tekkit server, and although i am looking up how to, I have not altered the settings.

EDIT: Oh wait.. You don't even need fuel in 1.3, right? Or is that in both 1.3 and 1.4?

You don't need fuel in 1.3.

Wow. What an idiot.. Thanks guys! Hahaha..

Also, a good way to test whether a function exists is to fulfill its parameters (such as putting fuel in the selected slot, in this case), and then using it in an if statement. Most functions return true if they fire.

Just check if turtle.refuel then or print(type(turtle.refuel)).

But yeah, no refuel function in 1.3.
