So apologies if this has been asked before,

I am looking to build a sentence with random strings that will be stored in a table.

For example:

    text = {}
names = {"a", "b", "c"}

name = names[rnd(2)] <-- doesn't work :(

foo = {
    str = "Hi my name is" .. name
}

Everything I have found is in the Non P8 version of Lua.

name = names[flr(rnd(#names))+1]

In Lua you can have non integer tables indices, you need to round the random value (float) to an int.

rnd() doesn't return an integer. also table indices start at 1:

name = names[1+flr(rnd(2))]

if you need this a lot you could use:

function rndt(t) return t[1+flr(rnd(#t))] end

name=rndt(names)

Thank you!

Can save a token by using ceil instead of flr

name = names[ceil(rnd(2))]

@Davbo: of course! ceil was (finally) added 6+ months ago. still not wired in my brain I guess ¯\_(ツ)_/¯

I'm not sure that's a good idea:

rnd() can return 0.0, and ceil(0) == 0.

Awjeez. I gotta find some tokens.

@Felice: of course! (－‸ლ)
