I have a question about how angry birds was created. What I mean is when the bird hits the boxes or barriers how does that effect work? It seems when you hit them they fall,..well tumble is more like it. Very smooth and it looks like real boxes or whatever is falling to the ground,..not just straight down and they also can take a hit and not all fall until they are hit harder. Would this be some sort of physics code needed to do this? Does anyone have any idea of how it's done or have an example of this? Seems very complicated.
Thank you.....
