    Computers, Programming and Robotics in Minecraft

    About ComputerCraft

    ComputerCraft is a modification for Minecraft that’s all about computer programming. It allows you to build in-game Computers and Turtles, and write programs for them using the Lua programming language. The addition of programming to Minecraft opens up a wide variety of new possibilities for automation and creativity. If you’ve never programmed before, it also serves as excellent way to learn a real world skill in a fun, familiar environment.

    Visit the official ComputerCraft Website to Download ComputerCraft

    ComputerCraft is funded by donations and merchandise. If you enjoy the mod, please consider making a donation, or buying a 3D printed pet turtle! The more I get, the more time I can afford to spend making the mod even better!

    Original thread lies below:

    Introducing ComputerCraft!

    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, Monitors adding external large external displays and Printers adding printing capabilities.

    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, kill monsters, mine resources, dig tunnels, control redstone on the move, craft, move and sort items, 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:

    1. Install [Minecraft Forge] version 601 or above for Minecraft 1.5.1
    2. Download ComputerCraft from one of the links above, and place it in the "mods" folder in your minecraft directory.
    3. You're done! You should now be able to run the game, and start crafting and placing computers.
    4. (Optional) If you wish to edit or add to the programs that come installed with ComputerCraft, create a new folder called "ComputerCraft" in your mods directory, extract ComputerCraft1.5.zip there, and delete the zip.
    First, build a Computer (or its Advanced counterpart):

    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 to craft some 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 and interact with the world. Add some coal to the turtle and fuel up your turtle with "refuel", then try experimenting with the "go", "excavate" or "craft" 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. 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!

    New in ComputerCraft 1.42 is the Printer:

    Place a printer down next to your computer, supply it with paper and ink, or dye of any colour, and print messages for your friends! Either interact with the printer yourself using lua, or print documents using the "edit" program! Try feeding a printed page back into the input and changing the ink to print in different colours!

    That covers the basic features of ComputerCraft, and the potential for amazing automated creations should be clear. Visit the forums at http://www.computercraft.info for help with Lua, programming, and to view and download programs and creations created by the community. If you make anything cool yourself, remember to share it with the world!

    For the full list of program and API changes, type "help whatsnew" at any computer ingame.

    • If you join an SMP server with different Block IDs in config/ComputerCraft.cfg or config/CCTurtle.cfg than the server, your game may crash. To rectify this, delete the config files, or set the IDs to their default values.
    • Reloading the game or restarting a server while a Computer or Turtle is running a program will reset that program, unfortunately this is an unavoidable result of the Lua scripting engine used, can cannot be fixed. If you want a computer that always runs the same program, set it as the "startup" script.
    I authorise and encourage people to create and distribute lua programs for ComputerCraft however they see fit (try the forums at computercraft.info!). I also give permission for ComputerCraft to be included in any and all mod packs, provided that the ComputerCraft files are included completely unmodified. If you include ComputerCraft in a popular modpack, please consider donating to the development of the mod.

    This looks pretty nice :smile.gif:
  • #7
    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.

    But what better reason to learn programming? :biggrin.gif: 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.

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

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

    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!"
    Playing Minecraft Since September 12th 2010 - Alpha 1.1

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

    org.luaj.vm2.LuaError: assertion failed!

    RvsB forevar!!!
  • #20
    And this...is compatible with everything?!?

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


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