Is there a way to pick random values from a table that aren't numbers?

Help and Feedback Scripting Support
#1

I am trying to create a spinning effect on a name roll for a game im working on. I have a table with all the names but I dont know how to make it pick random ones before settling on whatever it lands on.

I’d like to avoid just running a set of names because you would then, see it every time.

local CNRs = {
	--Ult

	guy1= .05,
	guy2= .05,
	guy3  = .05,
	guy4= .05,
	guy5= .05,

I already have it to where it selects a name from a string, but I want it to randomly scroll through a set amount of names in my table before finishing, is that possible?

Thanks.

Not sure if this is what you mean, but I thought of a way

-- This section counts how many
-- elements are in the dictionary
local length = 0
for _, _ in (table) do
	length += 1
end

-- This section picks a random
-- element from the dictionary
local counter = 0
local chosenIndex = math.random(1, length)
for key, value in (table) do
	counter += 1
	
	if counter == chosenIndex then
		-- THIS WAS CHOSEN WOOHOO!!!
		
		-- break out so it doesn't go past the chosen value
		break
	end
end

Would this work if I already have code that picks the winner? If I dont change anything, and hit spin, it will give me a random name like I want. Just the idea of having it spin is what im looking for.

Can I see what your code that picks the winner looks like?
I really don’t understand what you’re asking

#5 
game.Players.PlayerAdded:Connect(function(Player)
	local Character = Player.Character or Player.CharacterAdded:Wait()
	local Humanoid = Character:WaitForChild("Humanoid")
	
	local CNRs = {
		--Ult
		
		guy1= .05,
		guy2 = .05,
		guy3  = .05,
		guy4= .05,
		guy5= .05,
	}
	
	local sum = 0
	for _,Values in pairs(CNRs) do
		sum = sum + Values
	end
	
	local function getRandomItem()
		local ClanValue = Random.new():NextNumber(0, sum)
		for item, value in pairs(CNRs) do
			ClanValue = ClanValue - value
			if ClanValue < 0 then
				return item
			end
		end
	end


local DataFolder = Instance.new('Folder',Player)
DataFolder.Name = "DataFolder"

local Clan = Instance.new("StringValue", DataFolder)
Clan.Name = "Clan"

local Clan1 = Instance.new("NumberValue", DataFolder)
Clan1.Name = "Spins"
Clan.Value = getRandomItem()
Clan1.Value = 5000

end)

local RS = game:GetService("RunService")


local debounce = false

RS.Heartbeat:Connect(function()
	if debounce == true then return end
	debounce = true
	script.Parent.Text = game.Players.LocalPlayer:WaitForChild("DataFolder").Clan.Value
	task.wait(1)
	debounce = false
end)

I don’t see an issue with this script? It looks like it gets the random item just fine

#7

Okay let me show you an example,

https://gyazo.com/ddaf5cc53e9daf53da21734f6e6c50a8

Here its spinning through random names, but its the same 5 names before it lands on the value its supposed to land on. I want it to display all different names at all times, if that makes sense.

#8

You can index like this or just access it without indexing:

table = {
  guy1 = 0.5,
  ["guy2"] = 0.5
}

table.guy1
table["guy2"]
#9

Doesnt that defeat the idea of it being random? If I am putting in select ones to loop through?

#10

Maybe you could do something like:

table["guy" .. tostring(random)]
#11

I used the guy1 naming stuff as an example, what about for just regular names?

#12

Maybe you mean something like this:

local randomKey = keys[math.random(1, #keys)]
local randomVariable = myTable[randomKey]
#13

Im not that great at scripting, what is the “key” referencing?

Here is what I have if this helps any more,

spinning script

As you can see from that, I have like 5 names that it circulates through, but its those same names every time. So what I am trying to do is make it go through any of the names in that clip to make it seem more genuine, if that makes sense.

#14

Well you don’t have to do it like that but you can do it like this:

local randomNumber = math.random(1,#table)
local chosenValue = table[randomValue]
#15

Basically, you have to convert the table into an array. Like this:

game.Players.PlayerAdded:Connect(function(Player)
	local Character = Player.Character or Player.CharacterAdded:Wait()
	local Humanoid = Character:WaitForChild("Humanoid")

	local CNRs = {
		--Ult

		guy1 = .05,
		guy2 = .05,
		guy3 = .05,
		guy4 = .05,
		guy5 = .05,
	}
	
	local keys = {}
	for k,v in pairs(CNRs) do
		table.insert(keys, k)
	end
	
	local DataFolder = Instance.new('Folder',Player)
	DataFolder.Name = "DataFolder"

	local Clan = Instance.new("StringValue", DataFolder)
	Clan.Name = "Clan"

	local Clan1 = Instance.new("NumberValue", DataFolder)
	Clan1.Name = "Spins"
	Clan.Value = math.random(1, #keys)
	print(Clan.Value)
	Clan1.Value = 5000
end)

If you need more information, you can check the following post, the OP explains in detail how it works.

I tested it so it should work.

#16

I couldn’t find out a way to incorporate this in my own…

https://gyazo.com/6986e26cb615baf11e0a19eeeb68b7f7

While there is no error, it is just giving me numbers. Was there something I was supposed to change?

#17

If you want to get the value instead of the index number, you can do the following:

game.Players.PlayerAdded:Connect(function(Player)
	local Character = Player.Character or Player.CharacterAdded:Wait()
	local Humanoid = Character:WaitForChild("Humanoid")

	local CNRs = {
		--Ult

		guy1 = .05,
		guy2 = .05,
		guy3 = .05,
		guy4 = .05,
		guy5 = .05,
	}
	
	local keys = {}
	for k,v in pairs(CNRs) do
		table.insert(keys, k)
	end
	
	local DataFolder = Instance.new('Folder',Player)
	DataFolder.Name = "DataFolder"

	local Clan = Instance.new("StringValue", DataFolder)
	Clan.Name = "Clan"

	local Clan1 = Instance.new("NumberValue", DataFolder)
	Clan1.Name = "Spins"
	Clan.Value = CNRs[math.random(1, #keys)]
	Clan1.Value = 5000
end)
#18

Isn’t this the same script as the one above?

#19

No, this line is different, now it assigns the value instead of the index.

#20

Yeah this isn’t working for me, and I dont understand.

I’ve scrapped the changes and just put it back to what I had, Here are the three scripts I am using.

https://gyazo.com/a8f957d6339b2ca48d7648f4679edb24

This last one is the one I don’t want to use, but am using to make the spin effect.
