Introduction to Programming with ComputerCraft

Note

This article is still a work in progress.

Open Minecraft, go into a singleplayer creative world, then place down an "Advanced Mining Turtle". A turtle is essentially a robot that can move around, break and place blocks, and a couple of other things depending on what tools you give it.

SwitchCraft 3 introduction for new players

SC3 is a minecraft server built around computercraft. Apart from CC:Tweaked, Plethora, and a few homebrewed mods, there is not much else in the modpack. This gives the game a very vanilla+ feel which manages to have a rather extended endgame due to progression not being the main focus. You probably joined for the computercraft mod, and this tutorial will get to it eventually, but first let me introduce you to all (most) of the new items from all of the mods:

Computers

Computers: Blocks that execute arbitrary Lua code.

Rules:

You will be given the coordinates of the cache (aka. chest), but they will intentionally be slightly (or not so slightly) wrong. The coordinates listings will be paired with a measure of how accurate they are. (measured using chebyshev distance)

Example:
Listed coords: 100 69 420 (10 blocks accuracy)
Actual coords: 97 79 412

While searching you are not allowed to use a block scanner, chorus fruit, ender pearls, or break blocks, unless the cache specifies you may do so.

	-- SETUP:
	-- have a turtle with an entity sensor on its right (to detect player presence) and wireless modem on its left (for shopsync)
	-- have slots 2-16 full of dummy items (gold swords, for example), only leaving slot 1 empty
	-- and finally, place a chest below the turtle (that's where received diamonds will be stored)

	Exchange is a programming language in which atoms traverse lines and exchange numbers.

	Atoms:
	Atoms are unordered lists of positive integers (1, 2, 3, etc.). You can create a constant stream of new empty atoms with a >> symbol at the beginning of a line, or a single empty atom with a > symbol at the beginning of the line. You can also destroy atoms with a > symbol at the end of a line.
	Example:
	>----------->
	Here an empty atom is created and then immediately destroyed.
