hi guys, a facebook member wrote me this... but i have no idea how to do that..I post the his answer here:
the internal canvas resolution - the window size you've set for the project - can be set at runtime, which changes the size of the window the game renders to. The layers in each layout are then scaled based on the new window size to fill the screen. This allows the game to be full screen at any resolution, and it is no longer locked to the monitor resolution.
let me know
