It is unanimous, that one of the most popular iPhone and iPad app till date is Angry Birds. Starting from its highly amusing and catchy music and sound effects, to the adorable animated character and the highly engaging game itself, there is hardly an Apple user who hasn’t played this game.
The popularity of this game can be estimated by the fact that this game is now playable in web browsers too, Google Chrome being the pioneer web browsing application to allow its users to play a mini-version of the game.
Have you ever wondered how to actually play and master the game? Have you ever wondered whether the birds and the catapults along with your swing, acceleration and tap have a relationship or is there just a random pattern the shots follow? Have you ever wondered whether physics or math comes into play when taking an aim at the pigs on the other end of the screen? If you have, you are thinking along the same lines as Wired’s Rhett Allain.
He has been consistently applying the concepts and theories of physics and math to this game, which to the masses appears to be a mere source of entertainment and game play. By measuring the vertical and horizontal velocity and acceleration of the birds, Rhett Allain, tries to undercover the dynamics of this successful app.
But what about the physics? Do the birds have a constant vertical acceleration? Do they have constant horizontal velocity? Let’s find out, shall we? Oh, why would I do this? Why can’t I just play the dumb game and move on? That is not how I roll. I will analyze this, and you can’t stop me.
A small excerpt for math lovers:
Just to check, let me make a plot of the magnitude of the velocity right before the tap vs. the acceleration during the tap. Oh, it looks like all of the shots have the yellow bird accelerating (due to the tap) for 0.067 seconds. Of course this acceleration could just be due to the screen capture frame rate.
It doesn’t look like there is a simple relationship here. It also doesn’t look like the tap-acceleration is constant. The magnitude of this acceleration ranged from 124 m/s2 to 336 m/s2.
