Where can i learn LUA?

I know this much

print 'this is all i know' -- outside of single
--[[ and muli-
line comments]]
print "BLAAAAAAAAAAAAH" --------- and its case sensitive and two dashes minimum NOT 2 EXACTLY

and that's it where did you learn?

Please try to search for your question to see if it already has an answer - this one especially has been asked countless times.

I'm going to start you off with saying that your use of print there is a function call with an argument.

What you wrote there is actually just syntactic sugar for this:

print('this is all i know')

The parentheses can be dropped because the only argument given is a single string, although I suggest that you never drop them. Using them adds readability without detracting from speed literally at all.

I suggest you try to read through this tutorial.
