ComputerCraft 1.51 is released!

Posted on by

It really is!

Downloads:

ComputerCraft requires Minecraft version 1.5 and an up to date version of Minecraft Forge. Once forge is installed, drop ComputerCraft1.51.zip into your /mods/ directory, and launch the game.

New Features:

  • Ported to Minecraft 1.5
  • Added Wired Modems
  • Added Networking Cables
  • Made Wireless Modems more expensive to craft
  • New redstone API functions: getAnalogInput(), setAnalogOutput(), getAnalogOutput()
  • Peripherals can now be controlled remotely over wired networks
  • New peripheral API function: getNames()
  • New event: “monitor_resize” when the size of a monitor changes
  • Except for labelled computers and turtles, ComputerCraft blocks no longer drop items in creative mode
  • The pick block function works in creative mode now works for all ComputerCraft blocks
  • All blocks and items now use the IDs numbers assigned by FTB by default
  • Fixed turtles sometimes placing blocks with incorrect orientations
  • Fixed Wireless modems being able to send messages to themselves
  • Fixed turtle.attack() having a very short range
  • Various bugfixes

I’m quite proud of this update. Wired networks are something people having been asking for for a while, and I’m really excited to see what people can achieve with them, especially their ability to control peripherals at a distance. ComputerCraft is also a Minecraft 1.5 mod now, which means Computers and Turtles can interact with all cool new redstone features of the latest update. As always: Thanks to everyone who helped with beta testing, and Happy Hacking!

  1. I droped the ZIP-file into my mods folder. When I run Minecraft it works just fine until I try to open one of my worlds. I don’t know why it crashes. The mods that are already installed are: Minecraft Forge, Rei’s Minimap and Inventory Tweaks. If someone of you could help me it would be awesome.

      • that would be the case, but computercraft 1.51 requires minecraft 1.5 to run, and currently FTB runs on minecraft 1.47.

      • Now I know why it was not working
        It was because of Rei’s Minimap it needs an other Modloader. Well thanks for your help ^^

    • try to download it on skydaz i use skydaz to get all of my mod and the work great when i open the it on mine craft try using the mod loader the some come with you can drag them into the mod loader and they install onto your minecraft also it depends what system you use like forge the one i use and allot more

  2. Good job Dan and Cloudy! I was looking forward to the wired networking features and you also finished some bugs that bothered me 🙂 Though I’m not downloading, as RedPower hasn’t been updated to 1.5 (yet). Great job anyways!

  4. I know that this is still far off (based on the update to 1.3/4) but theoretically, would it be possible for the cables to be covered by either BC Facards or RP2 Microblocks?

  6. I found a bug: the front texture of the advanced computer looks, when the computer is turned off, like the other sides (has no screen)

  7. Thank you Dan200 for all of the hard work you put into this mod!! I love coding LUA with this mod, its very awesome :D.

  8. It would be nice in the future to have real network stuff integrated. Like routers and switches and computers us ips. Then one could make DHCP, DNS, SQL and web servers. Good progress though.

      • That is true, but if you did not want all your computers running on one network cable bus, then there would have to be a device that can connect 20 or 30 computers. Someone should make a mod or apis that integrate Cisco routers and switches.

  10. I noticed an error in this post.
    The new “setAnalogOutput()” function is listed two times in a row aside the 5’th bullet under “New Features”

  11. Hey there,
    Love the new update! One thing, can’t find the new wireless modem recipe anywhere. Just curious what that might be.
    Thanks!

  12. This is what i have been needing for a while, with misc peripherals aswell the wired connections are going to be a great help, good job cloudy and dan!

  13. hi this update looks EPIC but it will not work in 1.5.1 I installed forge that is fine but when I add cc mc will not load it say the FLM thing then mojang for 5secs then black screns
    please help me 🙂

  14. I have a Crash on Mac at Loading Minecraft:

    Minecraft 1.5.1 (Mac)
    Forge 1.5.1-7.7.0.602
    Java 7 Update 17 (Build 1.7.0_17-b02) Original not Apple Java

    Any Idea?

  15. Good job! I’m very interested in the new cables.
    Also I would like to ask you for some kind of hot-fix for 1.4.7 because of FTB and many mods that aren’t in 1.5 yet, and to be honest we both know that it would take time for FTB to get updated. so if you have the time just hot-fix for the bug fixes.
    Thank you :). (The bug with the melee turtle is annoying as hell)

  16. If I read the bug fix correctly you stopped the wireless modems from being able to send to themselves?

    I’m currently having an issue getting my elevator program to work and I think that might be the cause. I was writing it using variables so that I could write it once for all the computers and it would still function, but not being able to send a signal to itself makes me have to modify the code for each machine! Any way around this fix?

  20. Нave уou ever considered creating an e-boo&X6B; or g&X75;est authoring on other blogs?
    I have a blog based upon on the same iԁeas you dіscuss and w&X6f;uld lo&X76;e to
    have you share some ѕtοriеs/information.
    I κnoω my audie&X6E;cе would enjo&X79; your
    worκ. If yo&X75;’ге eνen remοte&X6c;y interested,
    feеl fre&X65; t&X6F; send me an e mail.

    Here is my ωe&X62; si&X74;e 3d cover maker software

  21. Hello there, just became aware of your blog through Google,
    and found that it’s really informative. I’m going to watch out
    for brussels. I will appreciate if you continue this in future.
    Numerous people will be benefited from your writing. Cheers!
