Please provide more explanation in your question. If you explain exactly what you are trying to accomplish, it will be much easier to answer your question correctly.



local allPlayers = {}
for a,v in pairs(game.Players:GetPlayers(2)) do
        table.insert(allPlayers,v)
end
local plrAmount = game.Players.NumPlayers
math.randomseed(tick())
local val1 = game.Players.NumPlayers, plrAmount 
local val2
repeat wait(5)
    val2 = game.Players.NumPlayers 
until val2 ~=val1

allPlayers[val1].Character.Torso.CFrame = CFrame.new (0,0,0)
allplayers[val2].Character.Torso.CFrame = CFrame.new(665.995,7.1,-115.005)

its not changing into lua form sorry ): berrythebetta 20 — 9y

Select the whole script, press the Lua button. There should be one row of tildes (~~~~) above and one row below. You can edit your post by pressing the button at the right. BlueTaslem 18071 — 9y

First of all, you can't use HTML tags in Lua.

<pre class="brush: lua"> -- ... ... ...
 </pre> -- This isn't HTML, so this can't go in your script

Also, you can't put 2 in game.Players:GetPlayers(2). GetPlayers() is a function that gives you a table of the Players. It doesn't have any parameters.

I've added some annotations so you can read what is happening.

-- Pick two random players.
-- This is accomplished by creating a table of all Players, then picking two random numbers to correspond with players in the table. 


local allPlayers = game.Players:GetPlayers() --Create a table of all the players

-- #allPlayers is the amount of players in the game

math.randomseed(tick()) -- Seed the randomizer so we can get a different sequence each time we generate one

local val1 = math.random(1, #allPlayers) --Pick a random number between 1 and the amount of players (inclusive)


local val2;  --Predefine a variable for later

repeat val2 = math.random(#allPlayers) --Pick a random number again
until val2 ~=val1 --Keep picking a random number until it is different from the first random number

-- Now teleport the players that correspond with the two random numbers

allPlayers[val1].Character.Torso.CFrame = CFrame.new (0,0,0)
allplayers[val2].Character.Torso.CFrame = CFrame.new(665.995,7.1,-115.005)

Also keep in mind this script will not work very well if there is only 1 player in the server. Be sure the script doesn't run unless there are two players in the server. I recommend checking the value of NumPlayers

if game.Players.NumPlayers > 1 then
    -- Code
end
