How to get the last character of a string

[xMagmaDev (Terrainny)]

How would I get the last letter of any string using Sub()? Would I have to use a hashtag? If so, how?

You can start from the end using negative endpoints, so doing str:sub(-1, -1) will get you the last character.

You could use the length of the string to find the end: str:sub(#str, #str).

return string.sub(str, #str)
