1: We have no function called fs.setDir, what do you want to accomplish by calling that?
2: Are you sure disk.isPresent gives you attempt to call nil?

1. I fixed this.
2. That is the line it says. Maybe it is something near it.

AH! Got it. You don't close "dd" (the file handle) when you are done. That's the problem I think.

dd = fs.open("cookie/disk", "w")

local dd = fs.open("cookies/disk", "w")

LBPHacker, on 01 April 2013 - 07:37 AM said:

OK, tested it in-game, works perfectly. BUT you should change

dd = fs.open("cookie/disk", "w")

to

local dd = fs.open("cookies/disk", "w")

local is for the sake of Lua, cookies is for you are using the folder "cookies", not "cookie".

peripheral.getType(side) == "drive"

disk.isPresent(side)

Nope (I'm on CC 1.5 for MC 1.4.7), but disk API has been working the same for a long time now (except .getDiskID which is now .getID), I don't think that's the problem.

LBPHacker, on 01 April 2013 - 07:56 AM said:

Oh for goodness sake… I've just realized: you want to detect the disk drive itself, don't you? In this case:

Use

peripheral.getType(side) == "drive"

instead of

disk.isPresent(side)

That's because disk.isPresent checks the drive for a disk :D/>

I'm going to upgrade my version just for the sake of it. I'll post soon if it's either still broke or fixed.

The background color of the whole screen?

…

You mean how to wipe all the text and make the terminal full of one color? Just set the background color you want to use and then term.clear()
