Color3 pick from a table not working?

Help and Feedback Scripting Support
#1

so i have a table which the color3 for the gui takes from but it is not working, what did i do wrong?

local Variables = {
	"0.986007, 0, 0.0538186",
	"0.133196, 0.328206, 0.998352",
	"0.16817, 0.789593, 0.182605",
	"0.985275, 0, 0.720073",
	"0.99765, 0.875898, 0.0387579",
	"0.988525, 0.358038, 0.0314183",
	"0.48365, 0, 0.998444",
}



gui.TextColor3 = Color3.new(Variables[math.random(1,#Variables)])

This will not work because the Color3.new function requires 3 numeric parameters, not one string. In order to achieve this, using the table you have provided, feel free to use the added function below:

local Variables = {
	"0.986007, 0, 0.0538186",
	"0.133196, 0.328206, 0.998352",
	"0.16817, 0.789593, 0.182605",
	"0.985275, 0, 0.720073",
	"0.99765, 0.875898, 0.0387579",
	"0.988525, 0.358038, 0.0314183",
	"0.48365, 0, 0.998444",
}

local function convert(str)
    local spl = string.split(str, ", ")
    for i,c in pairs(spl) do spl[i] = tonumber(c) end
    return table.unpack(spl)
end

gui.TextColor3 = Color3.new(convert(Variables[math.random(1,#Variables)]))

hmmm i don’t think its working, theres an error saying

Players.foxnoobkite.PlayerGui.Cooldown.Frame.Shoot.Cooldown.LocalScript:20: attempt to index function with '0.133196, 0.328206, 0.998352'

maybe i have to just get the whole color3.new function in the table too?

Yeah, I made a mistake with my syntax. I made an edit.

#5

hmm nope, still the same black letter

gui.TextColor3 = Color3.new(unpack(Variables[math.random(#Variables)]:split(", ")))

You could probably just store the values as Color3 instead of a string.

#7

Their code works fine. Maybe you don’t have the gui variable set to the UI instance you are trying to change the color of?

#8

That wouldn’t work because the parameters are string, hence why I used a for loop in my function to convert the strings to numbers.

#9

If the string can successfully be converted to a number (where tonumber doesn’t return nil), it is counted as a number.

#10

You are correct, my apologies.

#11

Just so you’re aware a color channel to 2 decimal places is essentially the same as a color channel to 6 decimal places (at least in respect to the naked eye).

#12

This is the best way to handle this.

local Variables = {
    Color3.new(0.986007, 0, 0.0538186),
    Color3.new(0.133196, 0.328206, 0.998352),
    Color3.new(0.16817, 0.789593, 0.182605),
    Color3.new(0.985275, 0, 0.720073),
    Color3.new(0.99765, 0.875898, 0.0387579),
    Color3.new(0.988525, 0.358038, 0.0314183),
    Color3.new(0.48365, 0, 0.998444),
}



gui.TextColor3 = Variables[math.random(1,#Variables)]
