" It's much better to pick an aspect ratio, then scale the game to fit that. For example, instead of 1280x720, target the 16:9 aspect ratio. (Just enter any 16:9 resolution for the window size in Project Properties.) "
When I change the windows size to 16:9 it's turned to 16,768... so when enter 16:9 I only see a thin line of the game. I would like to create an HD game that fit IOS, Android and PC.
why it's 16,768?
I would like that the screen will show all the layout. and in some areas will make a little bit zoom.
