Unity UI completely transparent Image draw call

Questions & Answers

Hello!
I don’t know how to get touch events on the UI event system without having a graphic component attached. So what I usually do is have a Panel with zero alpha but does Unity actually draw this because if that’s the case then there will be a lot of overdraw. Is there a better way to get touch events with the event system?

Thanks

You don’t need to add ‘Image’ in Panel, you just add a component of implement ‘IPointerClickHandler’, so you can access click message in ‘OnPointerClick’ function.
