I was looking at some other scripts, and looked on the actual wiki, and didn't seem to find out what "~" meant. Can anyone help me answer this?

What does the "~" symbol do?

~ is part of a conditional operator. It is also known as "Not"
Example of '~':
~= is like saying "Not equal"
if (x ~= 0) then --If x "Is NOT equal to" 0
--Code
end
You can also use not in other parts of the conditional statement to determine if something is "Not".
Example of 'not':
if (not x) then --If NOT true, then
--Code
end
Let me know if you have any other questions!

So using ~ means anything besides that number?

Yes, in a nutshell. Remember that ~ by itself is not enough. You need to have the full operator ~= for it to detect if something not equal. You can also use it for strings or error checking! x ~= nil can check if something exists too!
