fading frame by enabling gui?

how make to frame fade out when parent gui enables

Misinterpreted your question as a request. You could use a simple loop to increase transparency every X seconds

for i = 1,10 do
	wait(0.05)
	--do thing
end

OR

repeat wait(0.05)
	--do thing
until frame.Transparency == 1

A repeat until loop

I Suggest You Use A Tween , Do It Like This

local TweenService = game:GetService("TweenService")

First, We Get The Tween Service, Then After That, We Make Info By

local Info = TweenInfo.new()

You can learn What to put on Parenthesses on :

After You Make the Info, What You Want to Do Is call A Reference For A Gui, Example

local Gui = script.Parent

Or wherever the GUI might be

Now Create A Goal, I usually make a table since i got used to it since i watched TheDevKing Videos

local Goal = {
	Transparency = 1
}

Now We Create, And Play The Tween By Using

local FadeOutTween = TweenService:Create(Gui , Info , Goal)
FadeOutTween:Play()

When using :Create(), The First Parameter Will be the Instance, Or What Part You Want to Change, Since We Want to Change GUI transparency to 1 smoothly, We put GUI, Second Parameter is the Info, Which We already made by Using "TweenInfo.new()", Third Parameter is the Goal, Or What Property You Want to Change Smoothly
