How would I shorten this script? Please help me with this transparency script! Thank you!

Alright.. So I'm new to programming and I'm wondering, how would I shorten this script..?

What I'm trying to achieve is to change the transparency of a texture as a way to present different advertisements.

My script should explain it all.

Script:

AdvertisementBoards = game.Workspace.AdvertisementBoards
Part = AdvertisementBoards.Part
Part2 = AdvertisementBoards.Part2
Part3 = AdvertisementBoards.Part3
Part4 = AdvertisementBoards.Part4
Part5 = AdvertisementBoards.Part5
WaitTime = 0.01

while wait() do
	
	
	Part.BloxyCola.Transparency = 0
	Part2.BloxyCola.Transparency = 0
	Part3.BloxyCola.Transparency = 0
	Part4.BloxyCola.Transparency = 0
	Part5.BloxyCola.Transparency = 0
	
	wait(45)
	
	Part.BloxyCola.Transparency = 0.05
	Part2.BloxyCola.Transparency = 0.05
	Part3.BloxyCola.Transparency = 0.05

You should look into the principles of iteration. What you're looking for here is a series of for loops, I believe.

I would also like to add that using while wait() do is very bad practice. I see a lot of developers doing this. They look at it, they think "ah that's fancy". It's not, it's bad practice. The reason for this being bad is because you're relying on the fact wait() returns a number, which is a "truth" value. Therefore, while wait() do technically doesn't fail. If for whatever reason the implementation of wait() changed, and it returned nil instead, this is going to fail immediately and the loop will never work. Imagine you have multiple of these across your game and many games, everything will break. You want full control of your condition. You don't want some global function controlling that - it could change at any time. It's bad code for many reasons.

As for your code, I wrote something which I'm not sure if it works, but here goes it:

local AdvertisementBoards = game.Workspace.AdvertisementBoards:GetChildren()
-- This will return a table {} of all of the children in AdvertisementBoards

local WaitTime = 0.01

local function fade(obj, args)
	local i,ii,iii = unpack(args) -- from, to, increment
	
	for val = i,ii,iii do
		
		obj.Transparency = val
		wait(WaitTime)
		
	end
end

while true do
	
	for _, part in ipairs(AdvertisementBoards) do
		
		coroutine.wrap(function()
			
			part.BloxyCola.Transparency = 1
			
			wait(45)
			
			fade(part.BloxyCola, {0, 1, 0.05})

			fade(part.LegendaryStudios, {0.95, 0, -0.05})
			
		end)()
			
	end
	
	wait(45)
end
