How to check the end of a string?

[onedaysnotice]

like suppose I have a string:

string = "abcdef"

how could I check a specific number of end characters so that I can do something like:

IF the end of string is "ef" THEN
....
END

thanks

Code: Select all

str = 'abcdef' --avoid using the global "string" as it's already used and you need it
if str:sub(-2) == 'ef' then --Thanks Kadoba (and Robin)
--etc.
end

Code: Select all

str = 'abcdef' --avoid using the global "string" as it's already used and you need it
if str:gsub(-1, -3) == 'ef' then
--etc.
end

I think you mean str:sub(-2).

Yep, I meant that

Yep, I meant that

Still sub, not gsub.

Oops, that's a typo

how do I truncate any excess chars?

like if i have
str = awasdawasd

how do I truncate every char after the 5th?

i've tried this

Code: Select all

		if player[i].actionString:len() > 5 then
			player[i].actionString:gsub(player[i].actionString:sub(6), "")
		end

among other things but none of them have worked

[Nixola]

Code: Select all

str = str:sub(1, 5)

This will keep the first 5 chars and cut away the others
