irregular shapes that overlap - ignoring the transparency for click event

Getting Started Newbie Questions

I am building a simple puzzle coloring app. The pieces are irregular in shape and the transparencies obviously overlap each other. Any way to make the click target match the visible area only?

Hi Matthew,

At this time, the only way to ignore sensory click in the transparent region of an image is to apply a mask to it, and set it so that the masked region is ignored. This process is described under “Hit Masking” in the masking guide:
