I haven't worked with strings in a while, and I'm trying to take the first 3 letters of a message that a player says.
I already have the function set up and everything. What is wrong with this?
game.Players.LocalPlayer.Chatted:connect(message)
if message.string.sub(1,3) == "abc" then
--code
end)
--Also, obviously don't worry about the LocalPlayer stuff, I have it set up with an actual playeradded event in the script. I just need help with line 2.
There are two ways to use string.sub:
string.sub(String, Beginning, End)
String:sub(Beginning, End)
Both these ways work fine. To use it in your script, you can do it like this:
game.Players.LocalPlayer.Chatted:connect(message)
if message:sub(1,3) == "abc" then
--code
end
end)
Or like this:
game.Players.LocalPlayer.Chatted:connect(message)
if string.sub(message,1,3) == "abc" then
--code
end
end)
NOTE: if you type "ABC", the if will return false because "ABC" is not the same as "abc". In order to detect uppercased messages, you'll have to make the string all lowercase, by using the string.lower(String) function
EDIT: I answered your comment
game.Players.LocalPlayer.Chatted:connect(message)
local Msg = string.lower(message) --This makes the message all lowercase
local P1 = string.find(Msg, "(") --This returns the first occurance of "(" in "Msg"
local P2 = string.find(Msg, ")") --This returns the first occurance of ")" in "Msg"
if P1 and P2 then --If both parenthesis are there...
local InMsg = string.sub(Msg, P1 + 1, P2 - 1) --This gets the text between the two parenthesis
if InMsg == "abc" then --If the message between the parenthesis is whatever...
--code
end
end
end)
Hope this helped!

Thanks!
Oh, also, one more question, how could I use strings to exclude certain characters? I want to excluded "msg", "(", and ")", and then only accept the things inside of it. I am currently using a string.sub to use all characters 5 and up, but that would include the parentheses at the end of the message. How could I get around this?
