[SOLVED] Any help with GetChildren() error ? [closed]

Hello, I am getting an error with my code when I use GetChildren(), but I don't know why that happens. I don't work with this type of function normally, and so I don't know how to fix it. Here's the entire code :

1local Color = script.Parent.TeamColor   -- TeamColor is a BrickColor value
2local P = script.Parent.Team:GetChildren()   -- Looks for the children of "Team" group
3 
4for i, #P do   -- This part I'm not sure if it works or not
5    P.BrickColor = BrickColor.new(Color.Value)
6    wait()
7end

Where is this script inside of? VariadicFunction 335 — 10y

Your code was just about right except two parts of it. When you use this method your going through a table of objects. So P is considered a table, and "i" is the loop (count). In tables there are numbered objects.

Example: P[1]

So when using this method you want to do P[i]. Also you want to do "for i = 1,#P". # means "Number" basically.

1local Color = script.Parent.TeamColor
2local P = script.Parent.Team:GetChildren()
3 
4for i = 1,#P do   --Use "for i = 1,#P do"
5    P[i].BrickColor = BrickColor.new(Color.Value) --Don't forgot P[i]
6    wait()
7end

UndiscoveredLimited's answer was more sufficient, I thought it was gone, but I guess it's not so I will just keep what I just edited. If you don't understand what for _ ,v in pairs(EXAMPLE:GetChildren()) do means then I suggest you take a look at the link below. Its the best that I could find in a flash.

1local Color = script.Parent.TeamColor
2 
3for _,v in pairs(script.Parent.Team:GetChildren()) do --This is more sufficient!
4    v.BrickColor = BrickColor.new(Color.Value)
5    wait()
6end

I hope you understand it better now.

Thank you very much for your answer. I never understood Pairs very well, but maybe I can get a head start now. TheArmoredReaper 173 — 10y
