layout transitions

hi,

is there a tutorial here that makes a transition on every switch to layout like fade to black(fade in fade out)?

thanks in advance.

Can either do it with effects : https://www.scirra.com/tutorials/384/scene-transition-with-shaders

or

With opacity of a layer/sprite : http://www.scirra.com/forum/solvedfade-from-to-black-layout-transitions_topic63292.html

Vary useful thanks :)
