Title: OnDragOver event?
Post by: ryanscottmurphy on January 19, 2014, 06:49:02 PM

Is there an "NGUI way" to deliver information about the UIDragDropItem that is being held over a UIDragDropContainer?

I'm in a situation where I'd like to grab a handle to the GameObject and check what's being dragged over a container before deciding how the container should react in response. It seems like it might be a pretty common so I'm curious if NGUI might have a technique for handling this.

I should mention, I realize that there's an OnDrop(GameObject) message - but I'm looking for information about something before it's dropped. (In other words, when it's entering and exiting a container).

I think some combination of OnHover for your container and tracking which object's OnPress started the drag should take care of that?

UICamera.currentTouch.dragged tells you what's being dragged inside any NGUI event.

Thanks to both of you! A combination of UICamera.currentTouch.dragged and OnHover() is exactly what I was looking for.
