Help Using table.find

#1

Hi, I am trying to make a system which will return the name of something from a table. Basically I want to check the table to see which name has a value of 1 from the list.

This is the table. (Ignore the fact all values are 0, It updates in game when something happens)

I would like to be able to check which one has a positive value for example if Godly = 1 I would like it to return the name Godly.

Folder1 = {
			Godly = 0,
			Eternal = 0,
			Unique = 0,
			Omega = 0,
			Demonic = 0,
			Zeus = 0,
			Artemis = 0,
			Frigg = 0,
			Loki = 0,
			Thor = 0,
			Unobtainable = 0,
			Impossible = 0,
			Broken = 0,
			Glitch = 0

		}

local function findPositiveValue()
for key, value in Folder1 do
if value > 0 then
return key, value
end
end

local itemName, count = findPositiveValue()

Assuming you only need to find the first value that is positive.

Yes, there would only be 1 positive value at a time, I will test this

So im trying to make it work when the player joins the server and for now im just trying to print the value so I can see it but it doesnt seem to have any result.

Players.PlayerAdded:Connect(function(Player)
	local function findPositiveValue()
		for key, value in ServerData[Player].Folder1 do
			if value > 0 then
			end
		end

		local itemName, count = findPositiveValue()

		print(itemName)
	end
end)

(only difference is the ServerData bit but thats just where the folder is stored)

local function getFirstNaturalKey(dictionary: {}): string
    for key, number in dictionary do
        if number > 0 then
            return key
        end
    end
end

local function getPlayerDataAsync(player: Player)
    local data

    while true do
        data = ServerData[player]
        
        if not data then
            task.wait()
        end
    end

    return data
end

local function onPlayerAdded(player: Player)
    -- There is a very good chance that the player's session data has not been set at this time.
    -- Consider handling this after setting the data rather than in a new event handler.
    local data = getPlayerDataAsync(player)
    local name = getFirstNaturalKey(data.Folder1)

    print(name)
end



for _, player in Players:GetPlayers()
    task.spawn(onPlayerAdded, player)
end

Players.PlayerAdded:Connect(onPlayerAdded)

Move this part out of the function to the end of the connection (between the two ends):

local itemName, count = findPositiveValue()

print(itemName)

And add return key, value to this condition:

if value > 0 then
end

Also make sure that Players is defined as game.Players. If not, replace Players.PlayerAdded with game.Players.PlayerAdded.

It should look like this:

game.Players.PlayerAdded:Connect(function(Player)
	local function findPositiveValue()
		for key, value in ServerData[Player].Folder1 do
			if value > 0 then
                return key, value
			end
		end
	end
       
    local itemName, count = findPositiveValue()
    print(itemName)
end)
