How do you make your character fade after pressing a button on a gui?

I am making a gui that will play an animation (which I have done already) and then the body will fade away and the screen will fade white(which I have done also). I just need help with making my character fade away when the gui button is pressed.

local TweenService = game:GetService("TweenService")

local Time = 1 -- Time (in seconds) it takes to fade
local Remove_Character = false -- If it should remove the character after it finishes

function fadeChar(character)
	for i,v in pairs(character:GetDescendants()) do
		if v:IsA("BasePart") then
			TweenService:Create(v,TweenInfo.new(Time),{Transparency = 1}):Play()
		end
	end
	wait(1)
	if Remove_Character then
		character:Destroy()
	end
end
