### Introduction

Welcome to this tutorial about Advanced Turtle Lumberjacks. See the Turtle Lumberjack Tutorial first.

### What are Advanced Turtle Lumberjacks?

Advanced Turtle Lumberjacks are basically Turtle Lumberjacks that can dig blocks above them. We first make the turtle dig the block in front of it and then move forward so the rest of the tree is directly above it.

## The Code

``` ```

``` turtle.dig() turtle.forward() while turtle.detectUp() do turtle.digUp() turtle.up() end while not turtle.detectDown() do turtle.down() end ```

This makes us check if there are no blocks to be dug, then we go down until we can't. That's it!

This is a lot more complex BUT this can create a row of trees and constantly monitor them to see if they have grown or not. Here is a link to a video showing what it does- ComputerCraft-Turtle-Tree Lumberjack ``` ```

``` -- advanced turtle lumberjack shell.run('clear') print("Please put Dirt in Slot 1, Saplings in Slot 2, and a log in Slot 3.") print("Number of Trees To Plant?") local x = io.read() local dirt, sapling, log = 1, 2, 3 -- get into position turtle.up() turtle.turnLeft() turtle.turnLeft() turtle.back() turtle.back() turtle.back() -- initial planting for i = 0, x do turtle.digDown() turtle.select(dirt) turtle.placeDown() turtle.back() turtle.select(sapling) turtle.place() turtle.back() turtle.back() turtle.back() end turtle.turnLeft() turtle.forward() turtle.turnRight() --chop trees while true do -- sleep for 30 seconds os.sleep(30) -- check all trees for any that have grown for i = 0, x do turtle.forward() turtle.forward() turtle.forward() turtle.forward() turtle.turnRight() turtle.select(log) -- if the tree has grown if turtle.compare() then turtle.dig() turtle.forward() -- harvest the tree while turtle.detectUp() do turtle.digUp() turtle.up() end -- return to the ground while not turtle.detectDown() do turtle.down() end -- plant a new sapling turtle.back() turtle.select(sapling) turtle.place() end turtle.turnLeft() end -- round the corner turtle.forward() turtle.turnRight() turtle.forward() turtle.forward() turtle.turnRight() turtle.forward() end ```

(Helpful tip: Save this to your computercraft/lua/rom/programs folder, then it will be on all turtles.)

``` --[[ Simple lumberjack program for the wiki. Assumes the turtle is in the bottom left corner of a 10 ahead and 3 to the right area of clear dirt or grass. Also, only works for oak saplings, since they can grow next to each other. ]]-- local saplings = 1 -- the slot where the saplings are turtle.select(saplings) -- select the saplings while turtle.getItemCount(saplings) > 0 do -- while more saplings in inventory for i = 1, 8 do -- plant 8 saplings in a row turtle.turnRight() if not turtle.compare() then -- if not a sapling, then a tree grew turtle.dig() turtle.forward() while turtle.detectUp() do -- dig tree out turtle.digUp() turtle.up() end while not turtle.detectDown() do -- back down to ground turtle.down() end turtle.back() turtle.place() -- put down new sapling end turtle.turnLeft() turtle.forward() end -- turn around and line up for next pass turtle.turnRight() turtle.forward() turtle.forward() turtle.turnRight() turtle.forward() os.sleep(30) -- sleep for 30 seconds to allow trees to grow end ```
