function MineTunnel()

local a = io.read()
print("Name the tunnel: ")
local  name = io.read()
a = tonumber(a)
local b = 0
while true do
turtle.digUp()
turtle.digDown()
turtle.down()
if turtle.detectDown() == false then
turtle.select(1)
turtle.placeDown()

turtle.up()

turtle.dig()
sleep(1)

turtle.forward()
b = b+1
if b >= a then
print("Tunnel "..name.." mined!")
rednet.open("right")

end

I copied this code from my API text. Wrote it myself with the help of some tutorials and stuff />. Everything is working EXCEPT the turtle wont place stuff when there is nothing under it when it is checking. I tried everything I know of but cant get it to work so im asking your help on this one.

The code works fine when I run. Everything looks good too. No typo's, proper syntax, with the exception of a couple of extra else's. But even with those it should work.

You don't need to do

else
end

you can just do

if 123 == abc then
do stuff
end

Works for me. Won't work at the bottom of the world on the admin layer. Just wondering if you're testing on a superflat.

Maybe it would be a good idea to check the sides and top as well? There might be lava or water spilling into the tunnel.

[PyromancerVx]

um what is the admin layer? I was testing in a normal world but near bedrock.

[OminousPenguin]

Turtle can't place blocks on level 0. I doubt you were that low... there's normally bedrock blocks on 2 and 3 as well.

[Luanub]

0-4 can have bedrock and are considered the "admin layer" if I remember correctly. You would have to be pretty deep for that to be the issue. Have you tried it anywhere else?

[PyromancerVx]

I think I tested it on ground level too. Didn't work

[libraryaddict]

This is working fine for me as well.

You can use

if not turtle.detectDown() then

instead of

if turtle.detectDown() == false then
