Monitor

2013-01-09T18:24:26Z

Pokepal101: "Damage value: unused" needs no clarification... It's just a regular block.

{{Block
|name=Monitor
|image=Iso_Monitor.png
|id=4094
|damage-value=Un-used
|is-peripheral=Yes
}}
The '''Monitor''' is a block that can display text on its front side. When several screen blocks are placed on the same plane, it will form a single monitor. It is useful for displaying information at a server spawn, showing a program on the monitor, and even showing the status of an IC2 reactor! (provided you have [[CcSensors]] installed)

==Recipe==
{{Crafting grid
|A1=stone |B1=stone |C1=stone
|A2=stone |B2=glass_pane |C2=stone
|A3=stone |B3=stone |C3=stone
|Output=Monitor
}}

==Using the Monitor==
[[File:Computer_w_DiskDrive_w_Monitor.png|frame|428x241px|right|A 2x2 [[Monitor]], connected to a [[Computer]], with a [[Disk Drive]] connected.]]
The command used to control a monitor: monitor [top, bottom, left, right, front or back] [the name of the command to display]

So, in this case, if you typed "hello" in the name of the program part, the monitor would display "Hello World!".

==Using the Monitor within the Lua interface==
The monitor can be summoned through a command or through coding with the Lua command.

The command used to control a monitor within the Lua interface: shell.run("monitor" "[top, bottom, left, right, front or back]" "[the name of the command to display]")

For example, here is a way of summoning the monitor through a command:

<tt>[[print]]("Hello Monitor!")

[[Shell (API)|shell]].[[Shell.run|run]]("monitor", "right", "hello")</tt>

== Peripheral Functions ==
'''''monitor'' stands for the variable you wrapped the monitor to.'''
''Example:'' monitor = peripheral.wrap( "top" )

Methods in ''italic'' are available on [[Advanced Monitor|Advanced Monitors]] only.

Coroutine (type)

2012-12-31T23:35:10Z

Pokepal101: Fixed example code. Added {{NeedsWork}}.

{{NeedsWork|Why is the safeguard there? What is its purpose? ''[[User:Pokepal101|Pokepal101]] 03:35, 1 January 2013 (MSK)''}}

''This is for the coroutine object. For the API, visit [[Coroutine (API)]].

Coroutines are objects that allow you to form multiple tasks at the same time.

== How to Make a Coroutine ==

Type 'lua' in the terminal.

To create a variable, you use the function [[coroutine.create|coroutine.create()]]. Inside the parentheses, you need to add a function.
First, make a function:

lua> function helloWorld() for i = 1,10 do sleep(1) print(i) end end

This will create a function named ''helloWorld'' that will print a consecutive number every second for 10 seconds.
Now that you have a function, create the coroutine using the function:

lua> local c = coroutine.create(helloWorld)

Note that you don't use the parentheses in the command. This is how a function looks like in variable form.
Now, let's run it:

lua> coroutine.resume(c)

First, is gives 1, but then returns... "timer"? What's that all about?

the "timer" you see there is a safeguard in case something harmful happens. However, assuming that the safeguard wasn't there, you will be able to both type commands and see the text appear there!

== Why Use Coroutines? ==

Coroutines are used to do multiple things at the same time.

However, only use coroutines when you believe you have no other choice, because many issues can occur with coroutines.
