How do I check for numbers in a certain part of a string?

Say this was the string: CHAN 1 AND 5 AT 255

How would I find only the number at the end or only 1 and 5? (I'm only using 1 and 5 as an example, other numbers will also be used)

Sorry if this isn't super clear, I can give more specific info if you need me to.

Hey AtlasTheFox,

You can easily achieve what you want with string patterns and string methods. There are many string patterns but, for your case you will need the one for digits which is "%d". There are also various string methods but, for your purposes string.gmatch() should do just fine. Also, you will need to learn about for each iterations. Anyways, below is a decent enough example of how you can just print numbers from a string.

####Example

local str = "CHAN 1 AND 5 AT 255"; -- The string with numbers.

for num in string.gmatch(str, "%d+") do -- For each iteration for all strings that are digits in the number. Also, if you notice I added a '+' at the end, that will get the part of the string where it first notices a number to the end where it reaches a space. If you were to change that to just '%d' it would print each number singularly. Try both out and you will see what I mean.
	print(num) -- prints the part of the string that is a number.
end -- end for the for each iteration.

##Well, I hope I helped in one way or another and the wiki pages are below.
