Testimonials
I'm not sure what that is [...] I don't know where that came from.
It is basically ComputerCraft. It has the turtles, and the computers, and writing Lua programs and all that stuff.
Features
Controlled using the Lua programming language, CC: Tweaked's computers provides all the tools you need to start
writing code and automating your Minecraft world.
While computers are incredibly powerful, they're rather limited by their inability to move about. Turtles are the
solution here. They can move about the world, placing and breaking blocks, swinging a sword to protect you from zombies,
or whatever else you program them to!
Not all problems can be solved with a pickaxe though, and so CC: Tweaked also provides a bunch of additional peripherals
for your computers. You can play a tune with speakers, display text or images on a monitor, connect all your
computers together with modems, and much more.
Computers can now also interact with inventories such as chests, allowing you to build complex inventory and item
management systems.
Getting Started
While ComputerCraft is lovely for both experienced programmers and for people who have never coded before, it can be a
little daunting getting started. Thankfully, there's several fantastic tutorials out there:
Once you're a little more familiar with the mod, the wiki provides more detailed documentation on the
various APIs and peripherals provided by the mod.
