*sigh* Thanks guys. I had 5 kids (7 - 11yo) who wanted to learn how to code. I had basic knowledge of lua and minecraft and thought i could handle it... although I didn't think about placing around the spawn area. Luckily I had the kids spread out and I moved away when I changed the code. Serves me right for trying to teach kids before I understood the basics.

Sorry for wasting your time guys, but thanks for letting me know.

Just checked. It is a big area (32 x 32). (184,66,272), (184,71,241), (152,68,240), (152,68,272)

I still cannot seem to work out how to unprotect it. Only mod installed is computercraftedu on forge. Google seems to show other mods I need to use.

Bug reports must follow the following format:

VERSION:
1.74pr37
DESCRIPTION:
Teaching kids how to use the visual editor. Program stopped at "move forward" and said "cannot enter protected area". Can no longer work on (or move into) the square that turtle should have moved in to.
EXPECTED RESULT:
The turtle should have moved forward
REPRODUCTION STEPS:
Created from visual editor
for n = 1, 20 do
for n = 1, 4 do
if turtle.detect() then
turtle.dig()
end
turtle.forward()
turtle.turnRight()
end
if turtle.detectDown() then
turtle.digDown()
turtle.down()
end
end

Corrected code
for n = 1, 20 do
for m = 1, 4 do
if turtle.detect() then
turtle.dig()
end
turtle.forward()
turtle.turnRight()
end
if turtle.detectDown() then
turtle.digDown()
turtle.down()
end
end


Once I corrected the code, the program worked fine. Although I am unable to work out how to unprotect the areas the turtle previously protected. If anyone can help on this, please let me know

Not a bug. This was spawn protection
