Attempt to call nil -- after running a program

Hello dear Pro's,

I have a problem with error "Attempt to call nil". It comes after running a program.
The program runs without problem, but then I can't use the Lua-console at the turtle.

For example: I let the program run and then I want the turtle to go back with turtle.back(). Then there is the error.

Why is this always coming after running a program?


Greetings

That'd likely depend on the content of your program. Odds are it's replacing the regular "turtle" table with one that doesn't contain the "back", "forward", "turnLeft", etc keys.

This is my program:

weitermachen = true
tiefe = 1
while weitermachen do
-- Graben
turtle.digDown()
turtle.down()
-- Graben abbrechen
success, table = turtle.inspectDown()
if table.name == "minecraft:bedrock" or table.name == "minecraft:lava" then
  weitermachen = false
end

tiefe = tiefe + 1
end
for j = 1, tiefe-1 do
turtle.up()
end

What can I do? What is wrong?

You are overwriting the "table" api with the results of turtle.inspectDown(). Use another name, such as tbl.

Thanks :)/>
