Any way to generate random letters?
I was wondering if there is any way to generate random letters, kind of like math.random(1,5) except for letters. Any help appreciated.

1 | function doText(numLetters) |
2 | local totTxt = "" |
3 | for i = 1,numLetters do |
4 | totTxt = totTxt..string.char(math.random(97,122)) |
5 | end |
6 | print(totTxt) |
7 | end |
8 |
9 | doText(12) -- Prints a string of a random 12 letters, this number can be changed; this is one of my outputs with 12: 'avbaajquwzgj' |
If you're curious, 65 to 90 happens to be the alphabet capitalized, while 97 to 122 is lowercase.

This is a very inefficient method since you have to perform a concatenation every iteration. See table.concat(). User#6546 35 — 9y

+1 point for the satire, but since I'd be adding the strings to a table anyway through every for loop to concat it at the end, it doesn't actually affect the efficiency. Still upvoting because I like satire. Legojoker 345 — 9y

doesnt really have much difference from mine.. lol TheDeadlyPanther 2460 — 9y

table.concat will actually be faster for very large input, but for this application there's not going to be big numbers (and concatenation's not that slow anyway) BlueTaslem 18071 — 9y

01 | local letters = {"a","b","c","d"} -- etc. |
02 | local length = 5 |
03 | local text = "" |
04 |
05 | for i = 1,length do |
06 | text = text.. "" ..letters[math.random(1,#letters)] |
07 | if i == length then |
08 | print(text) |
09 | end |
10 | end |
This prints a 5 randomly generated letters.

This is a very inefficient method since you have to print out all the letters of the alphabet into that table. See string.char(). Legojoker 345 — 9y
