If you want that ngui doesn't catch the events you can disable the component UICamera, this will not trigger any event of ngui
No, I mean how to avoid trigger the other events but still trigger the UI ?
If I have a cube in the scene, and if I click it, it would destroy.
However, now if the cube and the UI is overlapping and if I click on the UI, it would also destroy the cube too so I need to avoid it.
