The Hard Science of Making Videogames

PopSci delves into the 10 greatest technical challenges faced by game developers today, and the technology that will hopefully make them a thing of the past. At the top of every dev's wish list is increased realism: realisitic fire, water, enemy AI, material physics, etc. Here directly from the developers where the tech stands today, and where it will likely be tomorrow. '4. Artificial Intelligence - Problem: Once upon a time, the bad guys in videogames wandered around mindlessly, shooting at you while they waited to die. That doesn't cut it anymore. Players demand sophisticated enemies to fight and reliable in-game allies with which to fight them. Thing is, it's freaking complicated, and it eats up processor speed. "We're faking just enough smarts to make it work," says Mathieu Mazerole, lead engineer on Ubisoft's Assassin's Creed. Status: Imbuing characters in a game with lifelike decision-making ability involves employing the kind of high-level logic theories--learning decision trees, mobile navigation, finite-state machine models--used by top robotics engineers.'
