I think about adding menus in my games. There will be two kind of menus:
- full screen menus.
- pop-up in-game (for example the pause menu... the game scene will still be viewable behind).
How should I proceed? Everything put into the game scene, and I move/hide/Show according to the events? Or a very new layout including all the concerned assets.
Your opinion? Any examples?

Thanks in advance!
