code to seperate a letter out of a word

[stepping stone]

Hi,

 

Does somebody knows how to program this :ex. if I have the word "Wherigo", I want to look what the first letter of the word is, so in this example it's "w". Is there a way to check it?

Someone gives a word in player and I want to check the first letter of this word and use this letter to compare to another letter.

 

Thank you all

According to what I found in the Lua Programming Reference, you'd do this:

local s = "Wherigo"
if Wherigo.NoCaseEquals(string.sub(s,1,1),"w") then
 Wherigo.MessageBox{Text=[[This is the right answer.]]}
end

Perhaps I should have elaborated. The arguments in string.sub are:

1) The string from which you're getting a substring (i.e. getting the letter)

2) Counting from the left, the number of the first character you want to include. The numbering starts at 1.

3) The third argument tells lua the number of the last character, inclusive, to stop. I used 1 because you wanted just the first character. Alternatively, you could use a negative number to start counting from the back of the string. For instance string.sub(s,1,-2) would have returned "Wherig".

Thanks Ranger Fox, that's just what I wanted!

How will be the code if you do this with a variabel? Or isn't this possible?

 

Thanks

In my example, "s" is the variable. Remove the first line (where I set the variable) and change "s" in the second to the name of the variable you're using.
