A better way to get a random letter over choose("A" through "E")

[Bentley]

Hello. I want to make a typing game and I have a quick question.

1. I'm going to use random letters to make a string. These are my first thoughts on how to do it:

letter_total = 10;

for (var i = 0; i < letter_total; i += 1)
{
    letter[i] = choose("A", "B", "C"); // ...all the way to "E"
}

In the above example, each word would be 10 letters long, and each letter is randomized. Is there
an easier way to randomize the letter rather than choose("A"..."E")

Thanks for reading!

There is.

If you want any random capital letter, you can just use this:

chr(irandom_range(ord('A'), ord('Z')))

You can also do this:

var letters = "ABCDE";
var rand = irandom_range(1,string_length(letters));
var rand_letter = string_char_at(letters,rand);

chr(irandom_range(ord('A'), ord('Z')))

Wow, so that returns a random letter from A to Z?

Edit: Thanks jo-thijs, answered my question perfectly : )

Yeah, it does indeed. You have to convert that integer to a character with the chr function:

letter[i] = chr(irandom_range(ord("A"), ord("Z")));

Thanks for the reply. Your way looks much better.

Thank you lol, I didn't know "chr" was a function. I'll code it now.
