I used the tutorial taught this page here:
( just put http:// in front)
(By the way very good tips on various issues)
The instructions were these:
"*Firstly, Sep. your project window size to: 640, 960 (640px wide by 960px in height)
*Set in fullscreen browser mode to scale: Scale outer (Please note with outer scale, make sure any off canvas objects / sprites are far away from the edges or They Could be visible on larger screens)
*Set to orientations: Portrait
*Set Unbounded scrolling on all layers to: Yes
*Set layer to all sizes: 640, 960 (same as project window size) "
Unfortunately, when it test in Intel XDK emulator, I have white edges on the top or side of my game. Depending of the phone model, they changed position, did not understand exactly why.
Any tips on how I can make the scale of my game correctly? Obviously it will be in Portrait.
