Please help me with the following code if possible:

print("Press [Enter] To Unlock!")
event, key = os.pullEvent("key")
while not key == 13 do -- 13 is the key ENTER
os.sleep(0.1)
until key == 13 then
print("YAY")
end

It gives an error at startup, about a 'too close 'while' at line ...' I cut this out of some code so the number would be pointless to give, but if possible please help or correct this code. Thanks.

I am using notepad++ and I have closed the function it is in, and that is the only other thing that needs to be closed. I did try closing it but it seems as if "until" closes it as well... If that helps you.

While and Until are two separate types of loop, and Until .. then is not valid syntax.

print("Press [Enter] To Unlock!")
repeat
  event, key = os.pullEvent("key")
  os.sleep(0.1)
until key == 13 -- 13 is the key ENTER
print("YAY")

You got the while syntax wrong:

while <condition> do
  -- code
end
-- or repeat:
repeat
  -- code
until <condition>

So your code should be:

function someFunction() -- you said it's on a function
  print("Press [Enter] To Unlock!")
  repeat
	local event, key = os.pullEvent("key")
    -- removed the sleep, it's not necesary
  until key == 13 then
  print("YAY")
end

Ah, thanks.

Oh, a little detail: 13 is not the enter key, it's 28.

Unexpected symbol on the "Until" line.. I copied what you had said... :3

EDIT: fixed, sorry.

Derp, didn't see that you put a then after that. It should be:

function someFunction() -- you said it's on a function
  print("Press [Enter] To Unlock!")
  repeat
	local event, key = os.pullEvent("key")
  until key == 28 -- 28 is the enter key
  print("YAY")
end

Wow, thanks, I was just BARELY experiencing this problem. What had happened is I had found the correct key but got it confused from a thing for adobe keyboard IDs, which I though it was a static id for everything.

Minecraft (and CC) uses this key codes. In CC 1.4 there's a keys api that makes it easier.
