About alpha

[shokinhan]

I want to let the picture in some area's alpha, and the special area can triger can receive events.

I want to the new player gameguide. Because the guide need lock screen , but some special area need hilight and can receive event.

I'm sorta having a hard to figuring out what you mean, but colliders can exist independently of sprites and forward events to whatever object you want.
