How can I get 10 random values out of a table?

forgot how tables worked but if i remember correctly why not just a loop with “table[math.random(num1, num2)]”?

then again i might be goign stupid here

oh phew so im not really going stupid

Perform a for loop and get random values out of a table with math.random(1, #table)

#4

Something like this?

local tab = {142,51,61,67,72,992,82,2,8,145,636,163,63}
local tab1 = {}

for i = 1,10 do
	table.insert(tab1,tab[math.random(1,#tab)])
end

print(#tab1)
#5

So something like this?

	local Queued = 1
	repeat
		table.find(PlayersInQueue, math.random(1, #PlayersInQueue))
     Queued += 1
	until Queued == 20

Yo why not just use Queued += 1 im pretty sure Lua supports that

No like

local players = game.Players:GetPlayers()
local playersInQueue = {}

local maxPlayers = 10

for i = 1, maxPlayers do
   local plr = players[math.random(1, #players)]

   if table.find(playersInQueue, plr) then
      repeat
         plr = players[math.random(1, #players)]
      until not table.find(playersInQueue, plr)
      table.insert(playersInQueue, plr)
   else
      table.insert(playersInQueue, plr)
   end
end

You can just do this:

repeat
	table.find(PlayersInQueue, math.random(1, #PlayersInQueue))
until #PlayersInQueue == 20
#9 
local t = {} --Array of values.
for _ = 1, 10 do
	if #t == 0 then break end --Break loop if array reaches 0 values.
	local v = table.remove(t, math.random(#t))
	--Do something with the pseudo-randomly removed value.
end
#10

Do you care about duplication (is it okay if you get the same value twice)? Can you modify the existing array?
