Epox Thanx 4 ur help, but i already used the same way u just explain above (0,0 with anchor behavior).
My problem is not with testing the game as html5 game, but the problem when i convert it to phone application using PhoneGap.
If i test it as a html5 game on a website it works fine, but when i export it to PhoneGap the problem starts.
As u know when i export a game to PhoneGap i should set the fullscreen mode to "on scale mode" and the problem starts here because the layer with 0,0 parallax and scale rate 0 or 100 appears differently from phone to phone depending on the resolution and the size of the screen.
So do u have any idea about fixing this issue?
Thanx in advance and wish u a nice day.
