Hello! I need help I want to add this rabbithole effect where like the gui leaves in like a circle. Here is my code:



script.Parent:WaitForChild("BlackoutEvent").OnClientEvent:Connect(function()
	print("blackout")
	if db == false then
		db = true
		for i = 0, 20 do
			script.Parent.Blackout.BackgroundTransparency = script.Parent.Blackout.BackgroundTransparency -0.05
			wait(0.01)
		end
		wait(0.5)
		script.Parent["Baseball Bat Swing 6 (SFX)"]:Play()
		for i = 0, 20 do
			script.Parent.Blackout.BackgroundTransparency = script.Parent.Blackout.BackgroundTransparency +0.05
			wait(0.01)
		end
		db = false
	end

end)```

Does anyone have advice or is there a tweening style?
