What exactly is the difference between "window size" and "layout size?"
I generally just have both of them to be exactly the same: 640 by 480. I never figured out what the difference was between the two and I never really found a need to care. My crappy games seemed to work fine on various computers, and also on tablets after being downloaded from Amazon. I also always set the margins to 0,0 since I never figured out a use to have margins anyway. As you can tell, I am definitely a novice and don't really have a clue what the heck I am doing.
The only real reason I'm asking now is because I am trying to have the screen shake by using the "scroll to" effect. And evidently the only way to do that is to have the layout size larger than the window size. (I cannot use the 'unbounded scrolling' option enabled because it screws up the placement of my graphics -- I'm guessing because I generally have graphics float in/out of the screen).
Without getting into the specifics and likely confusing me even more, could somebody simply let me know what the precise measurements should be generally when creating a game for tablets for both the "window size" and "layout size" so that I can easily use the 'shake' effect without complicating things terrible. I'm guessing the same measurements can be used pretty much all the time.
Thank you greatly in advance.
