I have implemented throwprops functionality.also I am using blit mask but when I Implement scrolling using blit mask I want that user scroll using Blank area covered by blitmask i want that it should scroll.
I tried to set hitArea of Blit mask but then It stopped working.
TweenPlugin.activate([ThrowPropsPlugin]);
