This new tutorial from Netexl covers the process of creating a smooth transition from one Phaser State to another: "If you followed previous articles I wrote on making of a responsive game in Phaser, one task was to implement smooth transition from one state to another in the game. Phaser states work by loading new state in the view and removing old state from the view which happens instantly and does not give a transition effect as if we are changing the state (or screen). In a polished game you would want to implement something which gives an impression of a transition from one screen to another. For example a sliding effect where player sees one screen sliding out of the view and another screen sliding in giving impression that something is changing in the game."
