How do you pick a random value from a table?
Trying to get used to tables, and this won't work.
color = {"Bright red","Bright green","Bright blue"}
rand = math.random(1,#color)
for i=1,3 do
script.Parent.BrickColor = BrickColor.new(color[rand])
wait(1)
end
The brick starts out as black and changes to one of the colors and stops. No error in output, and I've tested multiple times. It should be changing colors 3 times, and it can't be changing to the same color 3 times in a row because I've tested it over 10 times and it always stays one color.

You're on the right track, within those brackets "[]" you would want to put math.random(1,#color) 1 is the index value of the first object in color, and #color is the amount of objects in color. math.random will then in this case chose a number between 1 and 3. M39a9am3R 3210 — 9y

I did what you said and it worked, so I'm guessing you can't use variables inside the "[]"? ghostblocks 74 — 9y

You can use variables *anywhere* you want. Perci1 4988 — 9y

Why is it that when I use the variable "rand" inside the brackets it doesn't change colors 3 times but when I use math.random(1,#color) inside the brackets it works? ghostblocks 74 — 9y

You are already setting rand to a number before you do the loop so in that loop rand is already set to that number, to make rand a different number each time you would declare rand = math.random(1,#color) inside your for loop :3 Ryzox 220 — 9y

end
You would have to declare the rand variable in the loop as you declare it as a random number outside the loop meaning once that loop starts it's using that same random number it picked at the start and not changing it every time it loops.

Thanks, this is the answer I was looking for. ghostblocks 74 — 9y

-- You wont need the table with this script, but if you want it, I'm sure this script is off-topic
--color = {"Bright red","Bright green","Bright blue"}
rand = math.random (1,3)
scriptname = Script --Insert script name here for error message (not important)
if rand = 1 then
script.Parent.BrickColor = BrickColor.new ("Bright red")
else
if rand = 2 then
script.Parent.BrickColor = BrickColor.new ("Bright green")
else
if rand = 3 then
script.Parent.BrickColor = BrickColor.new ("Bright blue")
else
print ("Error: Random number was not found. This script is now prepared to be deleted!")
print (scriptname.."is containing this error. Please go there as soon as possible")
end
