I was wondering how I could have a number separated from a string through script, Here's an example:
Word = "ROBLOX122"
print numbersof(Word) --Output would return "122"

So what I do here its creating function named what you want you can change that if you want but don't forgot to change the name when you calling your function too. Assert check if the type of the parametre taken is a string, after we're creating 2 table, 1 to got all of characters in the string and the other for returning the numbers.After, yeah after again, we're now taking all of letter in the text and insert it in the table named as > "String"> , then we're looking in the letter if the letter is a number and insert it in the table named as >"number"> else it does nothing.Finally we returning the table >number> and we're getting all numbers.
function findNumbersInString(text)
assert(type(text) == "string", "The parametre given should be a string !")
local String, number = {}, {};
local position = 0;
for i = 1, #text do
String[i] = string.sub(text, i, i);
end
for i = 1, #text do
if tonumber(String[i]) then
table.insert(number, position + 1, String[i])
position = position + 1
end
end
return table.concat(number, '')
end
local txt = "Hello152"
print(findNumbersInString(txt))
First of all, you would need to create a function that returns the numbers of this, which i assume you'd already known.
Anyways, let's get straight to the code. To do this, we'll need to set up a table of numbers, and we'll pick through the word to remove the letters. Try this:
function numbersof(Text)
local Digits={"0","1","2","3","4","5","6","7","8","9"}
local NumbersInText="" --Sets up string to return
for i=1,Text:len() do
local Valid=false --Sets up variable to decide if to keep the substring
for _,Digit in pairs(Digits) do
if Text:sub(i,i)==Digit then --Checks if the substring is a digit
Valid=true
end
end
if Valid==true then
NumbersInText=NumbersInText..Text:sub(i,i) --Adds to total string to return
end
end
return NumbersInText
end
Word = "ROBLOX122"
print(numbersof(Word))
Anyways, I hope this makes sense. I've tested it out and it works fine for me.

Based on the comments below (thanks so much for them, by the way!), I've decided to fix my answer;
example = "3Roblox122" -- Your string.
pattern = "%d+" Finds numerics in string
AllNumbers = {} -- Creates a table for you to store all of the numbers in
for match in example:gmatch(pattern) do -- Finds all matches in the pattern "%d+"
table.insert(AllNumbers, #AllNumbers+1, match) -- Inserts these values into a table
end
print(table.concat(AllNumbers, "")) -- prints them all out side-by-side and in order.
Again, thanks so much for helping me fix this answer :).

Its not work if Word = "3Roblox122" Its will only print 3.

This would work if you went ahead and did a loop.
