How do i make A brick change transparency when A brick touches it?

function whenTouched(part)
	if part.Name = "Name of the Ball" then
		local x = script.Parent
		x.Transparency = 1

	end
end

script.Parent.Touched:connect(whenTouched)

This script will allow the brick to change transparency when the ball (any other brick will not work) touches the surface of the brick. On the if part.Name = "Name of the Ball" line of code, change the text inside the speech marks to the name of the ball on the workspace or where ever it is located, if it is Ball then your code would be

function whenTouched(part)
	if part.Name = "Ball" then
		local x = script.Parent
		x.Transparency = 1

	end
end

script.Parent.Touched:connect(whenTouched)

Hope this works. Remember to insert this code in to a normal script, which should be inside the brick that you want to become transparent.
