[BrickColor] Why Does This Not Work? [Fixed]

doors is a list of Bricks.

Lists don't have BrickColors, so changing the BrickColor of a list won't do anything.

You want to set the .BrickColor of the elements of the list, that is, of the bricks listed in the list.

You can get the ith element of a list like this: list[i]. There are #list things in a list, so we can use a loop to have i go from 1 to #list:

for i = 1, #bricks do
    local brick = bricks[i]
    brick.BrickColor = BrickColor.new("Bright red")
end

There are other iterators defined that make this a little shorter/semantic:

for i, brick in pairs(bricks) do -- Figure out `brick` automatically
    brick.BrickColor = BrickColor.new("Bright red")
end

You want to be careful, though. If there are other things in the model that aren't Parts, this will error when you try to set their .BrickColor. We should add a check to be sure:

for i, brick in pairs(bricks) do
    if brick:IsA("BasePart") then
        brick.BrickColor = BrickColor.new("Bright red")
    end
end

Is the syntax corrected like

door.BrickColor = BrickColor.new("Cyan")

example??
