Why am I getting the wrong order on this team color table?

TeamColors = {
    Red = BrickColor.new("Bright red"),
    Blue = BrickColor.new("Bright blue"),
    Yellow = BrickColor.new("Bright yellow"),
    Green = BrickColor.new("Bright green"),
    Orange = BrickColor.new("Bright orange"),
    Teal = BrickColor.new("Teal"),
    Purple = BrickColor.new("Royal purple"),
    Pink = BrickColor.new("Pink")
} --Max teams: 8

function AddTeams(numberOfTeams)
    if type(numberOfTeams) == "number" then
        local number = 1

        for i,v in pairs(TeamColors) do
            if (number > numberOfTeams) then return end
            print("Index:" .. i, "Value:" .. tostring(v))

            local team = Instance.new("Team", game:WaitForChild("Teams"))
            team.Name = tostring(i)
            team.TeamColor = v

            number = number + 1
        end
    end
end

AddTeams(3)




--Output:
Index:Pink Value:Pink
Index:Purple Value:Royal purple
Index:Blue Value:Bright blue

The above script add teams to the game. However, when I test out the script, the order is wrong. I wanted the table to be like it is (Red, Blue, Yellow, Green, etc.). Why is it in the wrong order?

do you get different results if you change pairs to ipairs? vanilla_wizard 336 — 6y

Nothing really appeared in the output when I changed "pairs" to "ipairs". MrHerkes 166 — 6y

Oh now I feel stupid for asking that, it's a dictionary. You can't exactly sort a dictionary into a desired order. There's the problem. vanilla_wizard 336 — 6y

When you're using a dictionary, the index is no longer "1", "2", "3", "4", etc. As your output shows, it's now "Pink", "Purple", "Blue", etc. Unfortunately, you can't sort that in order.

"in pairs" doesn't care about the order of the indices, whereas "ipairs" does. You can't use "ipairs" on a dictionary.

One approach if you absolutely must have red come before blue is to simply have two tables and have their values match their indices so index 1 of one table corresponds to index 1 of another table.

local teamColors = {
    BrickColor.new("Bright red"), -- index 1
    BrickColor.new("Bright blue") -- index 2
}
local teamNames = {
    "Red", -- index 1
    "Blue" -- index 2
}

function AddTeams(numberOfTeams)
        if type(numberOfTeams) == "number" then
            local number = 1

            for i,v in pairs(TeamColors) do
                if (number > numberOfTeams) then return end
                print("Index:" .. i, "Value:" .. tostring(v)) -- output now 1, Bright red

                local team = Instance.new("Team", game:WaitForChild("Teams"))
                team.Name = teamNames[i] -- changed
                team.TeamColor = v

                number = number + 1
            end
        end
    end

I'd suggest using a nested table instead. RubenKan 3615 — 6y
