The Guardian's games blog convened a panel of engineers and other experts to talk about the current state of video game physics. A great deal of research is currently going on to make better use of multiple cores so that advanced physics tools and engines can take advantage of all the processing power available in modern computers. Many of those tools are being put to work these days to find more realistic ways of breaking things, and game developers are trying to wrap their heads around destructible environments. Mike Enoch, lead coder at Ruffian Games, said, "This idea of simulating interactions and constructing the game world similar to how you would construct the real world generates more emergent gameplay, where the game plays out in a unique way for each player, and the player can come up with solutions to problems that the designer might not have thought of." Another area that still sees a lot of attention is making game characters more human, in terms of moving and looking as realistic as possible, as well as how a game's AI perceives what's happening. "The problem is not necessarily in having the most advanced path-finding technique with large-scale awareness; we need to have more micro behaviors, with a proper physics awareness of the environment," said software engineer George Torres.
