Boolean (type)

Shuudoushi: fixed some wording and removed some un-needed bits

A '''Boolean value''' (or more commonly, "boolean") represents either a "true" or "false" value. A boolean value is not capable of holding any other data, such as ([[Int_(type)|integers]], [[Float_(type)|floating-point numbers]] and [[string (type)|strings]]) and is usually used by functions to state whether the function was successful.

Boolean values can be used in logic statements (as conditionals), and can also be expressed as binary, where <var>true</var> is a value of <var>1</var> and <var>false</var> is a value of <var>0</var>.

For a more in-depth and concise explanation of types, please consolidate with the [http://www.lua.org/manual/5.1/manual.html Lua 5.1 Official Manual].

Modems are blocks which can be used to transfer data between [[Computer|computers]], using the [[Rednet_(API)|Rednet API]] or the [[Modem_(API)|Modem API]].
To place a modem on a side of a computer, right-click to place the modem while sneaking.
To use the modems, you need to connect the modems to each other by placing cables.

== Example (Rednet API)==
* Place 2 computers and add modems to them by clicking the right mouse button while sneaking.
* Access them, and start Lua.
* Once Lua has started, type "[[rednet_(API)|rednet]].[[rednet.open|open]] ("<relative location to modem, e.g. left, right>")" on both computers.
* Check if there exists a connection: a dim, red ring should be found around the modem, closest to the computer/peripheral it is connected to.
* Type on one computer "[[rednet_(API)|rednet]].[[rednet.receive|receive]] (60)". This will make the computer freeze for 60 seconds, or until it has received a signal from the other computer(s).
* Now, type "[[rednet_(API)|rednet]].[[rednet.broadcast|broadcast]] ('<your message>')" on the other computer. This should send your message to all computers connected.
* Opening the first computer should show the message written on the second computer.

== Example 2 (Modem and peripheral) ==
* If you want to use a modem to communicate with a peripheral you might want to take a look at the [[Peripheral_(API)##Remote_Peripherals_using_Networking_Cables|Peripheral API]]

==Modem as a Peripheral==
To use a Modem as a peripheral, you need to either call a method directly using [[peripheral.call]](), or wrap the modem using the [[Peripheral_(API)|Peripheral API]]. Wrapped modems provide all functions listed in the [[Rednet_(API)|Rednet API]].

For this example, we have a Modem connected to the top of our [[Computer]]:

-- Immediately invoke a method without wrapping
peripheral.call("top", "open")

-- You can also "wrap" the peripheral side to a variable:
local modem = peripheral.wrap("top")
modem.open("top")

Shuudoushi: Minor spelling fixes.

__TOC__

== Missing & NeedsWork Pages ==
* The [[:Category:Pages_Needing_Changes|Pages Needing Changes]] list shows all the pages that have been tagged with <nowiki>{{NeedsWork}}</nowiki> or <nowiki>{{Stub}}</nowiki>. These pages either need more information, to be tidied, re-worded or adjusted, or just needs some TLC.
* The [[Special:WantedPages| Wanted Pages]] list shows all the pages that are missing (have been linked to, but aren't there). You should first check that the page being requested doesn't already exist (in case the person misspelled the page) and then, if you're feeling adventurous, put together a page. You can always come back, or tag the page with a <nowiki>{{NeedsWork}}</nowiki> or a <nowiki>{{Stub}}</nowiki> tag. If you need help, ask us! We don't bite.

== Additional Tasks ==
*[[Textutils_(API)|Textutils]] (Needs <s>5</s> 3 function pages, <s>2</s> 1 function description)
*[[Vector_(API)|Vector]] <s>(Needs link to page explaining or description explaining what a vector is and function pages)</s>
** <s>It now has a link to Wikipedia, but it doesn't use any of the method or example templates. Can we get this rectified? ''[[User:AfterLifeLochie|AfterLifeLochie]] 02:14, 29 November 2012 (MSK)''</s>
** Now has pages to every function in a standard template. May need to double check work for any broken links or missing pages. Examples and descriptions probably need work. ''[[User:MafiaMoe|MafiaMoe]] 18:38, 23 February 2013 (MSK)''
*[[Paintutils_(API)|Paintutils]] (Needs 3 function pages)
** It also doesn't use any of the methods or example templates. Can we get this rectified? ''[[User:AfterLifeLochie|AfterLifeLochie]] 02:14, 29 November 2012 (MSK)''
* Some links don't link to their correct pages, resulting in page duplication and wasting time deleting pages. Can sometimes be found in the [[Special:WantedPages| Wanted Pages.]]

== Wiki Admin Things ==
=== General Wiki Stuff ===
* <s>Random Links, such as mining_turtle via image links, any chance of removing them? </s>
** Uh, no. They're generated through templates doing weird things, and fixing them is a real pain (template re factorization, renaming files, etc). I have fixed some but not all. ''[[User:AfterLifeLochie|AfterLifeLochie]] 16:46, 29 December 2012 (MSK)''
