How to use math.random with brick colors? (ANSWERED)
I wanted to make a script so alot of different colored bricks come out of the ground but i dont know how to do math.random for brick colors i thought it was like this:
p.BrickColor = BrickColor.new(math.random(1,5), math.random(1,5), math.random(1,5))
Is that correct or no?

Use this
p.BrickColor = BrickColor.random()
You can use BrickColor.Random(), but note that it chooses from the available BrickColors; on average, it returns an RGB of (0.59, 0.56, 0.53), whereas a truly random colour generator should return an average of about (0.5, 0.5, 0.5). In other words, you'll be more likely to get a colour with a lot of red in it than you might expect (though it's unlikely you'd notice in practice).
If you want a more even distribution, use:
p.BrickColor = BrickColor.new(math.random(), math.random(), math.random())
The constructor is BrickColor.new(r,g,b), where r,g,b are between 0 and 1. math.random() without parameters gives such a number (though math.random() will never return precisely 1; it might return 0.999999 instead).
Using this method isn't perfect either, since the available BrickColors are not evenly distributed, but it's much closer, giving an average RGB of (0.50, 0.49, 0.50).
