Layout scale adjusts the scale of a layout. Indeed I would use this to control the zoom but before I can zoom I need to know how much. For that I need the resolution of the display....
For example. Lets say I have a game with 100x100. On a 200x200 device I would set the layout scale to 2. on a 300x300 device I would set the scale to 2... crop would fill out the edges... Basically I would scale by whole numbers but I need to know the display resolution to do this.
May question is - how do I find the resolution of the device?
