Here is the code:
turtle.select(1) while turtle.detectUp() do while not turtle.up() do turtle.digUp() end end h = turtle.getItemCount(1) for i = 0, h do turtle.down() end print("Blocks that were mined: ".. h)
here is the command for pastebin:
pastebin get YA77iB9n [insert name here]
How does it work?
Place your turtle below the tree or noob tower you want to cut down and run the program. Make sure it has enough fuel.
EDIT: Just changed it so it doesn't need any blocks to figure out what it's going to dig, and it mines any block above it. I can't test this atm, I'm currently on an iPod.
