Fade/Blackout GUI

So im trying to make a game and as your crashing you black out, I have a local script as my main handler and another gui for black out. You can see in the following picture of what I mean.

Capture

My code for when it happens as following, I want it to happen where it says blackf.Visible = true
button.Activated:Connect(function()

elc.Playing = true

e2c.Playing = true

wait(1)

p1:Play()

wait(7)

game.Players.LocalPlayer.PlayerGui.LocalScript:Destroy()

wait(10)

fire1.Enabled = true

fire2.Enabled = true

fire3.Enabled = true

wait(.1)

elc.Playing = false

engined.Playing = true

fires.Playing = true

fires.Looped = true

e1b:Destroy()

wait(3)

warna.Playing = true

warna.Looped = true

p2.Playing = true

wait(8)

blackf.Visible = true

atc1.Playing = true

wait(4)

p3.Playing = true

wait(1)

end)
