Turtle Building program

What this basically does is allows a turtle to build structures.
Heres the code
http://pastebin.com/6H92CE13

How to use it:

1. Download the code from pastebin
2. name the code "build" for the turtle that will be building

execute it like this

build <Building code>

then it will read from the building code, and build the structure.
You will need fuel in slot 1, and building materials in slot 2,3,4,6,7,8

How to make custom buildings:

basically what it will do is read one variable at a time from a string.
Please note the entire code for the building must be on line 1, and have no spaces

0 - Move forward without placing a block
1 - Build a block from slot 2 or 6 (Will move forward then place the block)
2 - Build a block from slot 3 or 7 (Will move forward then place the block)
3 - Build a block from slot 4 or 8 (Will move forward then place the block)
r - Turn right
l - Turn left
u - Move up (also places a block under it)
d - Move down

so basically a code like this

11r1r1

will make a 2x2 box

Heres a code i wrote for a small 5x5x4 house House
Needs wood in slot 2&6, glass in slot 3, glowstone in slot 4

Features:
Stops when out of building materials in slot 2 and 6
Auto refuels itself
DOES NOT STOP IF SOMETHING IS IN THE WAY

See what kind of structures you can make love to see what people come up with :D/>



Thanks to Bomb Bloke for the help with the code that made this all possible
