Hello everybody! 
Well, i´m developing a game where the player do not run, only can move up and down to catch objects that scroll horizontally), do you know where can i find a tutorial to do that or if someone know how to do it, can leave a few explication, i would be very grateful.
Thank you all 
You could simply make the player object only move up and down and spawn object that it catches outside the screen and add a force to them when they are created, in the direction you want with the speed you like.
For static backgroumd, just add it to another layer.
Hope it helps
Take a look on parallax scrolling example, it can be an idea, just according you would wish to adapt it vertically.
Hi man. Thank you for your answer 
So, i need to create 3 layers? one for the background, other for the player and other for the scroller objects?
