Well, i made a game but to convert it to mobile platform takes time. i made the button, set the parallex to 0,0 and it stayed, but when my character moved downwards, it didnt follow! help please!
The button has to be on separate layer with 0,0 parallax. That means no character and such on that layer.
this layer usually called : HUD so when someone tells you should put the score in HUD it mean in a layer with property = 0,0 parallax
Also, the HUD is always the top layer. If you want make health bar, mana, points, etc, just create these objects one time and place is on the canvas as "Global", so, they will not change when changing layouts.

not always it should be the top layer you can make it the 2nd background layer for example there is games with a moon in the top-left corner without moving , it gives a good effect sometimes!
