How would I randomly get more than one value from a table?

So basically I have a bunch of parts in the workspace all under a folder, I make a table by doing :GetChildren() of the folder, and I want to pick three random parts from the folder, how would I do that?

I think you would have to rename all the parts with the same name and at the end put a number, then use math.random to pick a random one between them, repeat this tree times and you will get a what you nees, something like this:

for 1, 3 do
math.random(“toolname”.. “toolname”..)

I have already tried this but I don’t know how to put it all into one variable, because I want to have all the random parts I chose under a variable

I don’t try ink you are able to do that because they are all different parts, I’m not a programmer so

local t = {"test1", "test2", "test3", "test4", "test5"}

local choiceIndex = math.random(1, #t)
local choice = t[choiceIndex]

print(choice)

You can make a loop after this to choose 3 values.

that only gets one value… lol rip

You would have to do for 1,3 do Before that

Then create a loop to give you 3 values.

how would I do that sorry im not that good with for loops tbh rip

local t = {"test1", "test2", "test3", "test4", "test5"}


for i = 1, 3 do
	local choiceIndex = math.random(1, #t)
	local choice = t[choiceIndex]
	print(choice)
end

but what if it chooses the same value? I want three different random values

This should do…

local function getItemsFromTable(t: {[any]: any}, n: number): {[any]: any}
	n = n or 1
	n = n < #t and n or #t
	t = table.clone(t)

	local _t = {}

	for i = 1, n do
		local v = table.remove(t, math.random(1, #t))

		table.insert(_t, v)
	end

	return _t
end

local t = {1, true, "Hello, World!", {}, "something else", false}

print(getItemsFromTable(t, 3))
local Partsfolder = game.Workspace.Folder -- Put the folder location here

local RandomParts = {} -- Table for storing the random parts

for i = 1, 3 do -- Get 3 random parts
	table.insert(RandomParts, Partsfolder:GetChildren()[math.random(1, #Partsfolder:GetChildren())])
      -- Insert each random part into the table RandomParts
end

You can do this (if you’re wondering how I can use table.remove like that as the object to insert into the table, fun fact that table.remove returns the instance you’re removing :slight_smile:):

local randomPartAmount = 3

local folderChildren = FOLDER:GetChildren()
local selectedChildren = {}

-- For a sanity check, we can just set randomPartAmount to the amount of parts in the folder, hence the script should never break, hence there's no need for a check in the for loop below.
if randomPartAmount > #folderChildren then
    randomPartAmount = #folderChildren
end

-- For loop iterating from 1 to the randomPartAmount (3 in this case).
for i = 1, randomPartAmount  do

    -- Get a random index between 1 and the length of the children table, which should be the number of parts in the folder.
    local randomIndex = Random.new():NextInteger(1,#folderChildren)

    -- Now, insert into the selectedChildren table the part from 'folderChildren' at a random index of the table.
    table.insert(selectedChildren, table.remove(folderChildren, randomIndex))
end

-- Print it out to see the results.
print(unpack(selectedChildren))

	if not table.find(chosen, choice) then
		table.insert(chosen, choice)
	end
end

Btw, in your script if the part was already in the table then it would just skip and the for loop would continue, meaning there’s a chance you get less than 3 parts in the table.

@xmthl’s script should be the solution here I’m pretty sure

I just clocked onto that, @xmthl’s script is much better than mine. I wrote it on phone.
