How do I get a random choice from a table? [closed]
The roblox developer website is not good for tables. How can I create a table with a few string texts, then it chooses and prints a random string from the table?

You can use math.random
Examples:
1 | local table = {"Apple","Orange","String"} -- Items table. |
2 |
3 | local value = math.random(1,#table) -- Get random number with 1 to length of table. |
4 | local picked_value = table[value] -- Pick value from table |
5 |
6 | print(tostring(picked_value)) -- Print picked value |
Pick a random player
01 | local players = {} -- Table |
02 |
03 | -- Add players to table |
04 | for i,v in pairs(game.Players:GetPlayers()) do |
05 | table.insert(players,v.Name) -- insert player names to table |
06 | end |
07 |
08 | if players[1] ~= nil then -- Check if table is not nil. |
09 | -- Pick random player |
10 | local value = math.random(1,#players) |
11 | local picked = players[value] |
12 |
13 | print("I got player " .. tostring(picked)) |
14 | else |
15 | print("Table nil") |
16 | end |
What does it do? takes a random number from 1 to the maximum length of the table.

1 | local table = {string1, string2, string3} -- make a table |
2 | local Chosen = math.Random(0, #table) -- random # |
3 |
4 | print(table[Chosen]) -- Print it |
I apologize for the lack of typing. Im on my phone right now so its very hard. Please leave any questions in the comments.

In Lua array indices start at 1. tab[0] will be nil unless explicitly defined User#24403 69 — 6y

yHasteeD also used this answer but whatever...
1 | local strings = {"hello", "hello2", "hello3"} |
2 | local random_number = math.rando({1, #strings) |
3 | local picked_string = strings[random_number] |
4 |
5 | print(picked_string) |
you can also combine strings like this:
1 | print("The chosen string is "..picked_string.."!") |
you can also change the variable names and what to print but I guess you already know that...
don't forget to type the previous variables otherwise Roblox won't know what picked_string is
