Abstract [en]

When Apple first introduced the iPhone it was thought by many to be groundbraking. The main visible difference was that the phone had no keypad, just a touch screen. Another interesting feature in this phone was the addition of accelerometers. With this the device knows the forces applied to it and therefore knows how it is tilted. In april 2010 Steve Jobs announced 85 million iPhone OS devices sold. This makes it a very interesting OS from a developers point of view.This project aims to explore those two new key features and the iPhone OS by implementing a simplified version of the game Mad Skills Motocross by Turborilla. This is a fast paced sideways scrolling motocross game with demanding physics simulation. The physics is modeled via high frequency (1000 Hz) Verlet integration. Important aspects of the project are therefore also if the iPhone can handle the game and if it still will be a fun game considering the changes going from desktop to iPhone.The results were a game playable on one track with accurate physics, running with a visible frame rate of 30 frames per second and some interesting insights in what you need to think about when developing for iPhone OS.
