Detecting whether or not a UITexture is completely on screen?
« on: May 13, 2015, 10:00:00 PM »
Hey Everyone,

I'm trying to make a draggable camera only active when the user has zoomed in enough that a particular UITexture no longer completely fits on the screen.  Is there a way to detect when any of the UITexture's edges are no longer visible by the camera?

Thanks in advance!

Okay, I just attached a collider to it and used the collider's bounds to get this information through Camera.WorldToViewportPoint().

If anyone knows if it's possible just through NGUI functions, it'd be cool to hear.

Have a look at UIPanel.IsVisible(a, b, c, d).
