im having a hard time with my teleportation system because i need to use :sub() for it to work but idk how :sub() works, can someone pls explain here is a line of a script to better explain
if game.Players:FindFirstChild(msg:sub(6)) then
how does the :sub() work?
sub(start, end) is the shorter version of string.sub(). It returns the part of the string from start to end. If you only give it start, the end parameter will automatically be assigned to #string.
Example of using sub():
local string = "Hello World"
local subbed_string = string:sub(7) -- Returns "World"
print(subbed_string) -- "World"
The above example uses only the first parameter to extract a part of the string. The second parameter automatically gets the #string argument, which is why it returned World.
yeah, @RobloxWhizYT is correct
If you mean the string.sub function, then it is a function that returns the substring of the given string. For example,
print(string.sub("abcde", 2, 4))
would print
"bcd"
(Or at least that's how it remember it)
If you want more information, i suggest looking here: http://lua-users.org/wiki/StringLibraryTutorial
look at the code above

What do you mean by sub()? Is it string.sub() or something else? Also if you have a code, please put it on your question.
here is code
What it does is if msg == "Hi there people", msg:sub() would return "ere people", because like RobloxWhiz said, it returns a substring from the start number (6 in your case)to the end number, (end of string in your case, because you din't assign one)
