Advanced Turtle Lumberjack (tutorial)

== Advanced Turtle Lumberjack ==
=== Introduction ===
Welcome to this [[:Category:Tutorials|tutorial]] about Advanced Turtle Lumberjacks.
See the [[Turtle_Lumberjack_(tutorial)|Turtle Lumberjack Tutorial]] first.

=== What are Advanced Turtle Lumberjacks? ===
Advanced Turtle Lumberjacks are basically [[Turtle_Lumberjack_(tutorial)|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 ==
<code>
turtle.dig()
turtle.forward()
while turtle.detectUp() do
turtle.digUp()
turtle.up()
end
while not turtle.detectDown() do
turtle.down()
end
</code>
This makes us check if there are no blocks to be dug, then we go down until we can't.
That's it!

'''Another Advanced Turtle Lumberjack'''

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- [http://www.youtube.com/watch?v=7rmB09b6wYk ComputerCraft-Turtle-Tree Lumberjack]
<code>
-- 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.up()
turtle.digUp()
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
</code>
