Peripheral (API)

2012-07-10T20:07:30Z

Techzune:

The peripheral API is for interacting with external [http://en.wikipedia.org/wiki/Peripheral peripherals], such as the disk drive and monitor. 
[[Console|Consoles]] and [[Turtle|Turtles]] are also considered peripherals and you can interface two adjacent computers, although in a more limited fashion compared to [[Rednet (API)|rednet]]. Both Computers and Turtles provide the same methods: ''turnOn'', ''shutdown'', ''reboot'', ''getID''.

==Methods==
{| border="1" cellpadding="2" cellspacing="0"
!style="background:#EEE" width="210px"|Method name
!style="background:#EEE" width="*"|Description
|-
|[[peripheral.isPresent]]( side )
|Returns '''true''' if a peripheral is present on ''side''.
|-
|[[peripheral.getType]]( side )
|Returns the type or peripheral present on ''side'', nothing returned if ''side'' is empty.
|-
|[[peripheral.getMethods]]( side )
|Returns a table containing all methods for peripheral on ''side''.
|-
|[[peripheral.call]]( side, methodName, param1, param2, ... )
|Sends a function call to peripheral located on ''side''. Return values match those of called method. 
'''Note:''' ''methodName'' is a string.
|-
|[[peripheral.wrap]]( side )
|Returns a handle to the peripheral located on ''side''. If assigned to a variable, it can be used to call all methods available from that peripheral, as if calling '''peripheral.call()''', e.g.: 
fdd = peripheral.wrap("left") 
fdd.someMethod() 
''- is the same as -'' 
peripheral.call("left","someMethod")
|}

Techzune: /* Cleanup */

Here is a bunch of tutorials!

== Cleanup ==

This tutorials section is badly in need of a cleanup. The only page here ''that is actually a tutorial'' is the "Hello World!" script, and everyone who's ever coded in any language knows that is the most basic script you can create, and always the first script for new languages.
''Every'' other page here is just throwing scripts at the user. The "Password protected door" page screenshots are ignoring ''all'' best practices. I'll be rewriting this section, if you want to help, use the current pages as an example of what ''not'' to do.
Tutorials should be for teaching, not showing off. [[User:My hat stinks|my_hat_stinks]] 11:13, 15 May 2012 (UTC)

I agree with you on that. I noticed that when I read through most of the tutorials, I was the one who wrote the Hello World tutorial and I will be helping with cleaning up the other "tutorials"...--[[User:Techzune|Techzune]] 21:06, 16 May 2012 (UTC)

== Hole digging turtle ==

=== Hole digging turtle ===

Here is a quick little code i made, it makes a turtle dig a hole, 4x4 and 4 deep.

local function Digpart()
turtle.digDown()
turtle.down()
turtle.dig()
turtle.forward()
turtle.dig()
turtle.forward()
turtle.dig()
turtle.forward()
turtle.turnRight()
turtle.dig()
turtle.forward()
turtle.turnRight()
turtle.dig()
turtle.forward()
turtle.dig()
turtle.forward()
turtle.dig()
turtle.forward()
turtle.turnLeft()
turtle.dig()
turtle.forward()
turtle.turnLeft()
turtle.dig()
turtle.forward()
turtle.dig()
turtle.forward()
turtle.dig()
turtle.forward()
turtle.turnRight()
turtle.dig()
turtle.forward()
turtle.turnRight()
turtle.dig()
turtle.forward()
turtle.dig()
turtle.forward()
turtle.dig()
turtle.forward()
turtle.turnRight()
end

Digpart()
Digpart()
Digpart()
Digpart()
turtle.up()
turtle.up()
turtle.up()
turtle.up()
turtle.turnRight()
turtle.turnRight()
turtle.forward()

Lets break it down, its quite simple, the first part creates a function, a function can be reused whenever you want, its just a good way of making things more, Tidy, next we have 4 parts that call the function, this makes the turtle dig the hole 4 times, making it 4 deep.
the next part, is very simple, it gets the little turtle out of the hole, so you don't have to climb down there to get your little friend back.
well, that's my little code, hope you enjoy it!

----
You know, you can use loops to run that function instead of having to type so many lines. --[[User:Onionnion|Onionnion]] 19:26, 15 May 2012 (UTC)

Hello World Tutorial

Techzune: Undo revision 1025 by Wukl (talk)

[[Category:Tutorials]]
This tutorial is for those who are just getting started with ComputerCraft.

== Creating the Program ==

Creating a Hello World program is a simple task and does not require much knowledge in Lua or ComputerCraft.
The first step is to create the program so we can edit it. Access your computer and type:
edit helloworld

You will now have a blank program that you can edit.

We can make the computer print "Hello World!" in three different ways.

To print it letter by letter, type:
textutils.slowPrint("Hello World!")
Please don't overuse slowprint as it can annoy some users.

To just print it, type:
print("Hello World!")

You can also use:
write("Hello World!\n")
Using \n will make the console go to the next line. (print does this automatically!)

Now, press '''CTRL''' and make sure Save is selected, then press '''ENTER''' or '''RETURN'''.
The program is now completed and saved, so let's exit edit mode.
Press '''CTRL''' and select Exit by using the arrow keys. Once selected press '''ENTER''' or '''RETURN'''.

To test it, type:
helloworld

Simple isn't it?

== What We Learned ==
* How to create a program.
* How to edit a program.
* How to "slow print" text.
* How to print text.
* How to save a program.
* How to run a program.

== Code ==
textutils.slowPrint("Hello World!")
print("Hello World!")

Startup

2012-02-15T02:54:03Z

Techzune:

[[Category:Lists]]
== Startup Scripts ==

If, upon booting, a computer terminal detects a script named "startup" in its root directory, this script will be run.

Similarly, if a disk is present in an attached disk drive containing a script named "startup" that script will be run.

=== Very simple auto-install script to set up a single-use terminal (e.g. password-protected door): ===
Disk contents:

/disk/startup (installer script)

/disk/startup.file (program to be installed on terminal)

The script could look like:

fs.copy("/disk/startup.file", "/startup")
shell.run("startup")

When the disk is placed into a drive attached to a terminal, and the terminal is rebooted - the startup file on the disk will run. This startup file serves only to copy the program you've named "startup.file" to the root directory of the terminal with the new name "startup" - this will then run each time the terminal is booted, eliminating the need for the disk drive.

Floppy Disk

2012-02-14T02:09:53Z

Techzune: Added usage and release changes.

The floppy disk does what floppy disks in real life did. It holds files, and computers with a [[Disk Drive]] attached can read it and write to it. This is useful for transferring files[[File:Wwc1P.png|frame|right|The recipe for a floppy disk.]]

== Usage ==
Access (Right-Click) a disk drive and place the floppy disk into the slot.

== Release Changes ==
*'''1.3''': Used for [[Turtle]]s' programming.
*'''1.2''': Initial Release

Place the console wherever you please, and just right click it to use.

This tutorial is for those who are just getting started with ComputerCraft.

== Creating the Program ==

Creating a Hello World program is a simple task and does not require much knowledge in Lua or ComputerCraft.
The first step is to create the program so we can edit it. Access your computer and type:
edit helloworld

You will now have a blank program that you can edit.

We can make the computer print "Hello World!" in two different ways.

To print it letter by letter, type:
textutils.slowPrint("Hello World!")

To just print it, type:
print("Hello World!")

Now, press '''CTRL''' and make sure Save is selected, then press '''ENTER''' or '''RETURN'''.
The program is now completed and saved, so let's exit edit mode.
Press ''CTRL'' and select Exit by using the arrow keys. Once selected press ''ENTER'' or ''RETURN''.

To test it, type:
helloworld

Simple isn't it?
