How to make the back image appear before the front image where it is scratched?
So I have 2 full screen sized images with different textures. One is on top of the other. What I want is to scratch on the screen over the top image which will cause the scratched portion of the top image to be banished, revealing the back image in the process.
One possible way that I found is to divide the front image texture into many small sprites than disable it when it is touched. It's not very efficient and doesn't give the effect I am looking for. Since I am doing it for mobile platform, I need more efficient solution. Are there any other better ways to do it?
