LockDoor - KOD_28

-- This code is copirighted and made by KOD_28 !
-- If you use publically you must quote its author

-- This code is meant to be used with the mod ComputerCraft for Minecraft

-- Before using the program you must go to root directory ( cd / )
-- Then create a data directory ( mkdir data )
-- then go in it ( cd data ) and create a pswd file ( edit pswd )
-- Inside pswd just write your password and save/exit the file
-- Then you can run the program and have fun with it ;)

local pullEvent = os.pullEventRaw -- These two lines prevent someone to stop your program using CTRL + T
os.pullEvent = os.pullEventRaw

local door = "left" -- This is the side of your output to the door
local jukebox = "right" -- This is the side where the disk drive used in guest function is attached to your computer
local otme = 5 -- otme = opentime, it's the time the door is openned
local ptme = 30 -- ptme = playtime, it's the time the computer plays the cd in the disk drive for the guest function
local guest = "guest"
local admin = "admin"
local adminpswd = "your admin password" -- This is your Admin pswd you can change as you want

local pswdFile = fs.open("/data/pswd", "r")
pswd = pswdFile:readLine()
pswdFile.close()

--Instead of explain all the function, I'll let you try the program and understand by yourself ;)
