We plan on supporting all aspect ratios and orientations for our project. We've gotten the basics down on how to use all the NGUI stuff, but what we were curious about was how the UIRoot deals with orientation changes. For example, right now our UIRoot is set to 1024x768, Contrained, and both "Fit" buttons are unchecked. So if we're working on a screen that's at that size, positioning a UISprite at 0,-768 will position the sprite at the bottom of the screen with the bottom half cut off (pivot is all centered). That makes sense since the screen height is 768. However, when we switch to Portrait mode, the screen size is now 1024, but to get the sprite positioned at the bottom, you don't set the Y to -1024, you still set it to -768. I'm sure there's lots of behind the scenes that explains this but it's a bit confusing for laying stuff out, especially with our less technical staff members who want to set up things at the bottom of a Portrait screen but the numbers don't make sense in the current orientation.
What we were thinking of doing is (both at edit time and run time) if an orientation change is detected, we'd update those numbers accordingly. So in landscape it's 1024x768 and in portrait it's 768x1024, so the layout positions would make more since.
However, since we're still not 100% sure how the UIRoot works behind the scenes, we were wondering if doing this is a horrible idea, a great idea, and what the reasons would be either way. We're going ahead with testing this but please let us know if there's any reason why this would be bad.
Thank you!!
