How do I prevent turtles from breaking tall grass?

[Pitaya4]

I'm making a system similar to Google Maps. I have got it working perfectly, however, turtles break tall grass when they move. Is there a way to not do that? They already avoid opaque blocks, is there an option to include transparent blocks too?

I belive that a turtle will be able to detect or inspect the grass, you could try using either of those functions before every movement, it will slow the movement down as the detect and, especially, inspect take a little bit of time to return.

Thanks! That did the trick. I just changed the statement for going down from:

Code Select Expand

repeat
  turtle.down()
until turtle.detectDown()
to

Code Select Expand

if not turtle.detectDown() then
  repeat
      turtle.down()
  until turtle.detectDown()
end

you could combine the if and the repeat until into a while loop

Code Select Expand

while not turtle.detectDown() do
    turtle.down()
end
