ComputerCraft - Now with Turtles and Monitors!



ComputerCraft is a Minecraft mod (with full multiplayer support) that adds in-game Computers. Each Computer has an operating system, a filesystem, a suite of builtin programs (including a text editor, a realtime Lua interpreter, and two games), and can be programmed to do anything you want with the easy-to-use Lua programming language. Computers can interact with redstone wiring and bundled cables from the RedPower2 mod, meaning they can be used to fully automate and control your worlds. With peripheral devices, the capabilities of computers can be expanded further, with Disk Drives adding the ability to transfer files between computers and play music, Wireless Modems adding Wireless Networking between machines, and Monitors adding external large external displays .

But that's not all!



Version 1.3 adds a new block to ComputerCraft: The Turtle. The Turtle is a small, portable robot, that can be programmed just as Computers, but with the added ability to move around the world, placing and destroying blocks as it goes. A Turtle with the right programs can be used to build structures, mine resources, dig tunnels, control redstone on the move, and a million and one things I haven't thought of yet. The machines have risen.

Since the release of 1.0, many prominent mod reviewers have recorded spotlight videos of ComputerCraft, and many talented players have recorded videos of their creations. Instead of cluttering up this thread with videos, here's some links to the best YouTube content:

INSTALL
For Players:

• Install [ModLoader] 1.2.5
  
• Install [Minecraft Forge] Recommended Client.
  
• Download ComputerCraft Client 1.33 from one of the links above, you will get a zip file called ComputerCraft1.33.zip
  
• Extract the contents of the zip somewhere on your computer, if you do this properly, there will now be a folder called ComputerCraft.
  
• Copy this new folder (not the zip) into the "mods" folder in your minecraft directory.
  
• If you've done all this right, you should now be able to run the game, and start crafting and placing computers.
  
• If you get error message about bios.lua when attempting to the use a computer or turtle, you've done something wrong, re-read the instructions and try again.

For Server Operators:

• Install [Minecraft Forge] Recommended Server.
  
• Download ComputerCraft Server 1.33 from one of the links above, you will get a zip file called ComputerCraftServer1.33.zip
  
• Follow steps 4-7 from the Player instructions above.

GET STARTED
First, build a Computer:

Then right click on its screen to interact. You're now in the command prompt. Type "help" for an introduction, then type "programs" to see the list of programs you can run. Try running some of them. Type "help" followed by the name of a program to find out what it does. Don't miss "worm" and "adventure"! When you're ready to start creating your own programs, type "help programming" for advice on learning the Lua programming language, then use "edit" to create programs or "lua" to just start entering code. All the programs and APIs on the system have their own help pages.

Want more? Build a Disk Drive and Floppy Disks like so:

Place the disk drive next to the computer, put a disk into the drive, and access your computer again. Type "list", and you'll see that each Floppy Disk has it's own folder. Now you can use the "copy" or "move" commands to move your programs onto disks, and carry the disks around to transfer files between machines! For some light entertainment, try putting a record into a disk drive and running the "dj" application.

Computer Disk Drives too static for you? Maybe you're ready for Turtles:

Access your Turtle like a computer, and you'll see the similarities. Turtles run programs just like Computers, but have access to new programs and a new API to make them move around. Try experimenting with the "go", "excavate" or "dance" programs. To write your own turtle programs, use "lua" or "edit" just as with the computer, and call functions from the "turtle" API. There's a lot these little guys can do.

For truly advanced worlds, try building Wireless Modems and Wireless Turtles:

Attach your modem to your computer (sneak-click to place it on the side), or craft it together with a Turtle, and you now have devices that can use the "rednet" API to wirelessly send each other messages to a range of 50 blocks. This is one of the more advanced areas of the Mod, and requires programming, but anybody who's used the internet knows the potential of wireless communication.

New in ComputerCraft 1.31 is the Monitor peripheral, build it like so:

Build lots of monitor blocks, and place them together, and you will see they expand to one contiguous display. If your computer is touching the display, it can be programmed to draw text to this screen, which will be visible to anyone who walks past. Try the monitor out by running the "monitor" program, like "monitor left hello". Try to find the secret program added in 1.31 designed especially for monitors!

That covers the basic features of ComputerCraft, and the potential for amazing automated creations should be clear.

If you make anything cool yourself, remember to share it with the world!

• The turtle cannot place all kinds of blocks correctly. Blocks with custom placement logic such as Pistons, Beds and redpower wires may misbehave.

I give permission for ComputerCraft to be included in mod packs, provided that I am notified, and the ComputerCraft files are included COMPLETELY UNMODIFIED, including all lua and text files.

Shit, son!

[Sunday13]

O_O I never thought this was possible, well, I never thought it would work well.

[RandomerJon]

Oh. My. Porking. God.

So downloading.

[Yadaization]

coooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooool bro just cool

[Pizxe45]

This looks pretty nice

[haveacold1]

how about iron blocks next time or iron ingots.

Hey looks beautiful, it would be cool if you could create a computer storage like they had in pokemon. It would only hold a certain amount of items and could lose item data if the computer screws up.

This would seem a little difficult for people who don't code in Lua, but over all, nice work!

[Amber Tonerre]

EPIC you just passed the boundaries of minecraft mods!

[pelican1015]

That looks awesome, I'll try it out sometime!

EDIT: Wow, this got popular fast!

[NOESHKY]

Looks very impressive

But what better reason to learn programming? It's a lovely language, used in loads of games, and I'd like to think i've made it as easy to use as possible in ComputerCraft. The source code to all the builtin programs is fully readable and modifyable, and there's an interactive lua prompt for experimenting in realtime.

[DanCraft]

Wow that is amazing, I guess anything is possible in Minecraft ^-^

[SwiftDeathSK]

I never thought minecraft could give me a nerdgasm but...

I've a suggestion. Can you make the text smaller on the prompt IMO it takes too much space.

[Joe.]

To be honest - when I first saw this I was like "Urgh, probably a really basic mod that adds nothing more than a block."

I saw it and my reaction was - "Genius, your my god!"

[Amber Tonerre]

this comes up when i use the computer mc doesnt crash though

org.luaj.vm2.LuaError: assertion failed!

[AznaktaX]

And this...is compatible with everything?!?

When I downloaded this, I expected that it would modify like ten or so base classes!

O_O

How many days or weeks(or even months, rofl) did it take you to make this mod?
