Why doesn't this part tween script work with multiple parts?

Hey greybird700,

The issue with your script is that you are putting in a table as the argument for TweenService's :Create() function and that can't happen because you need a UserData Value, not an Array. So, there's an easy fix for this, all you have to do is just use a for each iteration for the Array like so:

local TweenService = game:GetService("TweenService")

local parts = script.Parent:GetChildren()



local Info = TweenInfo.new(

3, -- Length

Enum.EasingStyle.Elastic, -- Easing Style

Enum.EasingDirection.Out, -- Easing Direction

2, -- Times repeated

true, -- Reverse

0 -- Delay

)



local Goals =

{

Transparency = 0.5;

Size = Vector3.new(15,15,15);

}

-- For each iteration with the 'next' method. Roblox calls it a 'generic for loop'. --
for _,part in next, parts do
local tween = TweenService:Create(part,Info,Goals)

tween:Play()
end

for _,part in next, parts do
	part.Transparency = 1;
end
-- For each iteration with the 'next' method. Roblox calls it a 'generic for loop'. --

##Well, I hope I helped in one way or another and have a great day/night.
