I will be direct on my question. How to detect pixel perfect collision? Just like a hitTest(), with alpha tolerance.
Or, I could be helped to use the bitmapData and make my own engine.
Yes, I have googled it. And please don't come with the normal "hitTest()" - it's not what I want.
use the bitmapdata hittest in conjunction with the bitmapdata draw() method to create a shape-based collision detection for your as2 objects.
Exactly what I was expecting you to teach me...
