[CC] Simple Password Lock Tutorial *

[sleawnis]

This Tutorial Is For People With Little/None Understanding Of ComputerCraft, Or Coding In LUA. Sorry If Its Too Simple, I Could Make It Better, But Want To Keep It As Simple As Possible (:

1) Making Your Program:

Code: Select all

edit startup

This Creates Your File, And As It Is Named Startup, The Computer Will Run The Program Each Time It Restarts.

2) Making Your GUI:


Print: This Makes The Computer Display The String, Sets Cursor To The Line Below
Write: This Makes The Computer Display The String, Sets Cursor To The End Of The String

3) Input:

Code: Select all

input = read("*")

This Makes The Computer Request A Input Of The User, In This Case A Password. The String Is Then Stored For Later.

3) If Statment:

Code: Select all

if input == "password" then

This Checks If The Input (defined earlier) Matches The Password

Code: Select all

rs.setOutput("left", true)

This Sets A Positive Redstone Output From The Left Side Of The Computer

Code: Select all

sleep(3)

This Keeps The Computer At The Current State (emitting redstone) For 3 Seconds

Code: Select all

rs.setOutput("left", false)

This Changes The Redstone Output On The Left To False

4) Else:

Code: Select all

else

Does The Following If The Input Does Not Equal The Password

Code: Select all

os.reboot()

Restarts The Computer

Code: Select all

end

Ends The Code

Fixes:

You'll Probably Notice, That When You Restart Your Computer It Sais This Above The Program:


You Can Fix It By Changing Your Code Accordingly:

Code: Select all

term.clear()

This Clears The Screen

Code: Select all

term.setCursorPos(1,1)

This Makes The Cursor Go Back To The Start Of The Screen


The Next Bit Allows Your Computer To Be Un-Hackable (well as much as possible)(sorry for no scrennies)

Add This At The Top Of Your Code:

Code: Select all

os.pullEvent =os.pullEventRaw
