My EXTREMELY simple password program.

I know it's very simple so please don't comment saying so, I am a not very good at lua and this is the first working program i have made.

The code:

Spoiler

local oldPull = os.pullEvent;
os.pullEvent = os.pullEventRaw;
function MyOs()
term.clear()
term.setCursorPos(1,1)
print("------------------------------------------------------------------------------------------")
print("	   MyOS v 1.1")
print("------------------------------------------------------------------------------------------")
print(" ")
end
user = "sabian"
pass = "cheese"
repeat
MyOs()
write "Enter username: "
un = read()
print(" ")
write"Enter password: "
pw = read("*")
print(" ")
if un == user and pw == pass then
MyOs()
textutils.slowPrint "Access Granted!"
print(" ")
end
until un == user and pw == pass

So.. MyOS?
A CC OS??
Or just a login?

Nice. Challenge: add an ability to register multiple users with tables.

Little hint… you wanted to make a new line by putting

print(" ")

Instead of doing that you can take that print out and write this in the enter password thing:

write("\nEnter password: ")

Putting \n in a string makes a new line, that that makes a new line AND THEN types new password.

That would be cool, databases.

it's just a password program, I might make it into an OS though.

So if I put that would it leave a line out and then put the text or would it just put the text on the new line?

@EatenAlive3 I don't really understand tables in computercraft, thanks for the suggestion though.

Tables.. Like databases

It will put a new line then write on the new line but since you used wire and not print the password will enter and te same line, the console will look like this:

Enter username: admin
Enter password: pass

You really should learn to use tables, or else when you start to do complex things, you are going to have a lot of trouble.
